Setting up Wi-Fi on the ZTE H118N Ethernet router

Setting up a ZTE router is one of the main stages of connecting to the network.

Moreover, regardless of what connection is used to access the network - wired or wireless - it will take a little time.

It does not affect the settings and models of routers - only the speed of Internet access and the method of distributing it to computers and other equipment depend on this characteristic.

Choosing a Router

Today, ZTE is one of the world's largest manufacturers of network equipment and other electronics. Of course, 3G/4G models are more popular, but there are still many adherents of universal modifications. The peculiarity of such devices is that they receive, process and transmit signals using fiber optic cable and mobile communications, Wi-Fi. The devices are manufactured in white and black colors.

It is worth noting that the manufacturer’s relatively inexpensive models fully meet the requirements of the average user.

ZTE E5501

The main advantages of the model are its attractive appearance, despite the fact that for many this is not the primary selection criterion, support for wireless communication technology, and the device is equipped with two external antennas that can amplify the signal up to 10 dBi.

As for the disadvantages, it is worth noting the lack of the ability to connect a 3G modem, as well as the use of other alternative methods of connecting to mobile high-speed Internet.

ZTE ZXHN H118N

This model is one of the latest. The average cost on the domestic market ranges from 1000-1200 rubles*. The device is equipped with a USB port for a modem, which makes it possible to connect to the mobile Internet. There are also WAN ports for organizing wired access.

ZTE 5502

Another modification, which in terms of functionality and price is reminiscent of the first model. The price is about 900 rubles. The appearance is quite stylish, but the device has practically no advantages over other routers - only wired access is possible, and Wi-Fi network distribution can be carried out exclusively in one band, with an average speed of about 300 Mbit/s.

It is worth highlighting another significant advantage of the model - reliable encryption of streaming information using WPA2, WPA/PSK technologies, etc.

ZTE MF283

This model is already capable of receiving the Internet using 3G and 4G LTE (that is, connecting via a SIM card), as well as simultaneously with two wired connections via a patch cord. In addition, you can connect a USB drive to the device to retrieve information from the Internet directly without using a personal computer.

ZTE MF283 is an ideal option for organizing a network infrastructure in a large home or office. External antennas are removable, which allows you to replace them with more powerful modifications.

ZTE MF28D

A universal router that works with both a mobile network and a wired connection.

Note! A wireless high-speed connection is provided by a SIM card installed in the router, and not by using 3G and 4G modems.
Additionally, the device can be equipped with two antennas, each of which can amplify the signal up to 3 dBi.

Features of setting parameters

There are 2 main ways to connect the device:

1. Organizing shared access to a 3G/4G Internet connection using a secure wireless network. You must first insert a SIM card.
2. Use any 10/100 Mbit/s Ethernet cable.

The ZTE MF283 router is capable of providing data transmission speeds of up to 50 Mbit/s, and when receiving it increases to 100 Mbit/s. An access point using a router is created quickly, without much effort. The device is designed for use in places where there are problems with Internet access.

Before starting to set parameters, it is prohibited to reset the factory settings through the control panel or using the Reset button. This action may make it impossible for the router to function in the networks of some providers. In addition, the original warranty for the device will no longer apply.

The ZTE MF283 model allows you to connect memory drives via USB to directly receive information and files from the Internet without using a PC.

Device characteristics and features

There are no special secrets or tricks in setting up and using the device. In recent years, network equipment from ZTE has been in great demand, despite high competition. This is due to the following features of routers:

• The device case is equipped with a special connector for connecting an external antenna, and modems also have a powerful internal antenna.
• All modems are high-speed and can operate in 3G and 4G modes in any corner of the planet.
• Ability to interact with a large number of operating systems: iOS, Android, Linux, MAC OS, Windows XP, Vista, 7, 8 and 10.
• Ability to interact with memory stores.
• All modifications are compact in size and light weight, making them easy to transport and take with you.

Additional advantages of routers from ZTE are the presence of slots for memory cards and SIM cards. Visually, their design is quite laconic, which is characterized by practicality and reliability. The surface is matte, so the device will not slip in your hands. The average weight of various modifications is 35-50 grams. Some models are equipped with batteries (rechargeable batteries), which can be replaced after time.

Description of the router

ZTE MF90 is a mobile router with LTE support.
The MF90 device is developed by the Chinese company ZTE and sold by the mobile operator Beeline with proprietary software. The model can operate in LTE 4G networks at frequencies of 2.4 GHz and 5 GHz. The average price of a router is 3 thousand rubles. at the provider's official outlets.

Under the body of the device there is a 2300 mAh battery, which allows it to work uninterruptedly for 6-7 hours. By default, it is possible to install an additional microSD memory card up to 32 GB. The router supports simultaneous connection of up to 10 gadgets.

Positioning and model range

The range of Beeline routers is represented by 3 models:

1. ZTE MF90+.
2. ZTE MF90.
3. Huawei E5573.

The MF90 model is positioned as a standalone access point with different use cases. You can take it with you to your dacha, educational institution, office or other place with an unstable connection. In addition, the device is suitable for landline Internet access.

Packaging and equipment

The router is sold in a small package with the traditional design of the provider. At the back there is information about model specifications, basic equipment and system requirements for installing software.

The kit includes a battery, charger, router, connecting cable, instructions and SIM card.

By default, a charging unit with a 1 m cable is provided. The package contains a warranty service card and operating instructions. The user manual is quite informative. The battery is offered in a separate box.

Appearance

Externally, the ZTE MF90 is a small white box, comparable in size to a pack of cigarettes. The body is devoid of any decorative elements or design accents. In front there is a miniature display with an indication, and below it there are 2 control buttons. The first is intended to turn the router on and off, and the second is to activate a connection using the VPS method.

At one end there are 2 connectors for connecting an antenna with special plugs, and also microUSB for communication with a computer.

How to connect a router

Neither beginners nor advanced users should have any difficulties with how to connect a ZTE Wi-Fi router. Setting up a ZTE router is not fundamentally different from the step-by-step algorithm for setting up routers from other manufacturers.

First of all, you need to check the equipment. ZTE routers come with:

• router;
• power unit;
• patch cord (network cable);
• warranty card, brief operating instructions and disk with software components.

The patch cord is connected to the WAN port. A cable is also inserted into the LAN port, but it must interface with the PC.

Important! When connecting several providers to a modem at once, you need to additionally install a splitter to filter the signal, and to amplify the signal, the network equipment can be equipped with external antennas.

After connecting all the cables, the device can be turned on using the button located on the back of the case. For example, when setting up a zxhn f670 (670) router, when you plug in the power supply, the indicators on the display light up; after a few minutes, the device will be ready for use. In some cases, the router may be presented in the form of a network card, and it may also require manual installation of software components and drivers stored on the disk that comes with the network equipment.

As for the web interface, there are no differences. In most cases, users do not need to configure anything on their own to operate normally. If you need to change the settings manually, you can enable the web interface or use the mobile application; just go to/log in to the device control panel.

Features of settings for different providers

Setting up ZTE routers differs slightly depending not only on the device model, but also on the service provider.

Among domestic providers, users most often choose the services of Rostelecom, Beeline and MGTS.

In addition to the fact that these operators have maximum coverage of the country, you can find a wide range of tariffs in their list of services.

When setting up a router to work with the Rostelecom network, you need to not only enable Wi-Fi (according to the standard method), but also perform the following steps:

For the correct operation of the ZTE router, which must work in the MGTS or Beeline network, the same steps are performed as for standard connection setup.

That is, entering a password and login, activating Wi-Fi and setting the parameters of Multi-SSID sections. At the same time, routers of this brand are no longer used for ADSL connections.

Creating an Internet connection and additional sections

After all the preparatory activities have been completed, all that remains is to set up the Internet connection. Configuration must be done directly through the device’s web interface. To open the control panel, you need to open any browser installed on your PC and enter the router management IP address in the address bar - 192.168.1.1. It is always written on a sticker located on the back of the device.

The first thing that will open is a welcome window, where you will need to enter your default username and password. After authorization, the control panel will appear on the screen. The general principles of all devices are similar; as a rule, the differences are only visual.

ZXHN H118N: setting

In order to set up the device and gain access to the World Wide Web, you will need to do some simple manipulations:

• First step. Open a browser on your PC. Enter the IP address. It is indicated on the router case. After which a window should appear with the text “Pre-flight preparations in progress!” If the connection was correct, then after a few minutes this message will be replaced by another with the approximate content “Your router is being configured.”
• Second step. User authorization is carried out in the portal at ya.ru. Here you will need to indicate the data provided by the provider in the contract, for example, number, city, login. It is also possible to change the name and password of the wireless network created in the menu of the ZXHN H118N router. Wi-Fi can be configured without entering user data. In this case, the default settings set by the developers will be used.
• Third step. Save the information and reboot the router. After that, all that remains is to check the Internet signal.

How to download and install firmware on a router

If the router starts to work incorrectly, for example, the Internet periodically disappears for no apparent reason on your phone or PC, then it is strongly recommended to update the software components on the device.

Important! If the owner decides to reflash the router, he should be aware that the factory warranty is lost, and if the software update is unsuccessful, difficulties may arise with unlocking. Sometimes it’s easier to change the device to a new one and reconnect.

You can download and install the firmware on the ZTE Wi-Fi router on the manufacturer’s official website. There are also many other third-party resources, but you should download files from them very carefully, otherwise there is a possibility that your PC system and modem will be damaged by malicious components. Run the file downloaded to your PC and that’s it, all you have to do is wait for the download and installation of updates to complete.

When choosing a remote access point, it is strongly recommended that you familiarize yourself with ZTE network equipment in more detail. The devices combine reliability, functionality and excellent build quality with an affordable price.

Source

Device firmware

To link the router to any other operator, you must first unlock it. This process is accompanied by some difficulties and requires skills.

For all operators

To unlock the device, you need to write several operations using the computer command line:

1. Enter the value cd/823ADB/adb in the command line menu that opens.
2. Type adv devises and launch adb shell.
3. After opening the router console, paste the value mv/etc/init.d/zlocknetapp /etc/init.d/zlocknetapp.bak.
4. To reboot the device, just type reboot in the console.

Ttl=64

Initially, this option was used for the MF823 series modems, but today it is also suitable for the MF90 line. The software package includes drivers and a firmware tool.

First of all, you should install the factory drivers. To do this, go to “Device Manager” and manually specify the path to the software source. The system will then automatically install the missing drivers. If the process does not start for some reason, you need to restart the program or device.

To link the router to another operator, you need to unlock it.

List of changes in DL_MF90_DECKER_SU_EUV1.00.00:

1. The firmware is based on software for MF90 version B10 from Beeline.
2. The TTL=64 patch in the kernel is used, i.e. TTL correction check.

Unlocking nuances

The simplest and safest unlocking method is to enter a special code, after which the router will be completely unlocked, and SIM-Lock will not return to its previous settings. In addition, the procedure performed according to such instructions will not void the warranty service.

To generate the code, you need to know the IMEI number of the device. Enter *#06# on the keyboard or remove the battery from the router. IMEI is located on the information label and contains 15 digits.

Then you need to go to the router settings and find the unlock code window.

Preparatory measures

First, let's spend a little time on the preparatory steps that need to be completed before moving to the router's web interface. If you haven't already unboxed your device and connected it to your computer, now is the time to do so. When choosing the location of the router, take into account the future laying of cables from the provider and provision of the local network. Thick walls and the presence of active electrical appliances such as a microwave oven can affect the quality of the wireless network signal, so take these aspects into account when choosing a location for ZTE products.

Now that the equipment is installed in the optimal location in your home or apartment, look at its back panel. Connect the cable from your provider to the connector labeled “WAN” or “ADSL”, and the local network wires to one of the four available ports, which are most often marked in yellow. Connect the power cable and click on “Power” to turn on.

Before logging into the web interface on the host computer, you should check some settings so that during the configuration process you do not cause network conflicts. This applies to methods for obtaining IP addresses and DNS servers. You need to open the adapter settings and make sure that this data is received automatically. For more detailed information on this matter, see a separate guide on our website by clicking on the link below.

We start this guide on the home page of the ZTE router. Want to change your IP address? You've come to the right place. We'll show you how:

Start by clicking Quick Settings on the left side of the page. Then click on LAN and DHCP Server just below that.

Step-by-step setup of ZTE routers

Unfortunately, most existing firmware for ZTE devices does not have an automatic configuration mode, so all further actions will be performed manually. When using specific models, the appearance of the Internet center may differ slightly from what you see in the images below. Don’t be scared, because you just need to get comfortable with it by finding the menu items, which we will discuss when analyzing each step. Before starting the first stage, you will need to log into the web interface. To do this, open your browser and write 192.168.1.1 or 192.168.0.1 in the address bar, which depends on the model you are using.

A login form will appear in which you need to enter your username and password. By default, each has the value admin, so you just need to indicate it in both lines and click on “Login” to log in to the web interface.

After a new window appears with information about the network status, proceed to the first step, thereby starting manual configuration of the device.

Step 1: Network Setup

First of all, it is necessary to ensure correct Internet reception from the provider. To do this, configure WAN or ADSL, which depends on the type of cable connected. Each Internet service provider should provide its customers with a form with information about indicating the correct parameters or post this information on its official website, because this is what they need to start from when taking further actions.

In the ZTE web interface, navigate to the “Network” section.

First, let's look at the most popular type of connection - WAN. If this is your connection type, open the "WAN Connection" category. Select the first profile or create a new one if there is none. If the IP address is obtained automatically and you have not received any instructions from your provider to change the standard settings, leave all default values. Owners of the PPPoE connection type will need to enter a login and password to log in to the network. The Internet service provider provides this information immediately after purchasing a tariff plan. Additionally, pay attention to the NAT option. It is enabled if virtual networks are enabled.

ADSL owners should switch to the appropriate category, where only the modulation type is selected. As is already clear, this information is also provided by the provider. If you are unable to find it yourself, contact the company's support service.

Set up the LAN section of your ZTE

zte password
This will take you to a new page.

You can now change IP address . Enter the desired address in the field. Don't know what you should change? Try 10.0.0.1

After this Subnet Mask. By default it is 255.255.255.0, and you should leave it at that.

Congratulations! That's all. Just remember to save your changes before closing the page.

Possible problems when changing the IP address of your local network

When you change your local network IP address, you are making a fundamental change to how your network functions and all the computers on your network will operate. When you apply these changes, you will lose your internet connection. Your router may reboot and take a couple of minutes to start responding again.

Also note that some computers may need to be rebooted after making this change before they can connect to the router or the internet again.

• While continuing to hold the button, turn off the power, and hold the button for another 30 seconds.
• Connect the device to the network again and hold the button down for another 30 seconds.

If everything is done correctly, the router should return to factory settings.

Appearance Features

What can definitely be attributed to the advantages of the ZXHN H118N is its design. The manufacturer did their best in this matter. Compared to most faceless models, this router looks impressive. Non-standard design solutions were used for the body. In appearance, it can be compared to a small pillow, which is mounted on a stand. Unlike other devices, this router is installed in a vertical position, which can be considered an advantage, since air access to the ventilation holes always remains open.

The body is made of simple plastic. The color of the device is white. Dimensions: width – 110 mm, height – 50 mm, depth – 125 mm. Weight – 145 g. There are nine indicators on the front panel at the top. There are corresponding symbols next to them. There is a USB connector on the side, but it does not work with the firmware from Dom.ru. On the back panel there are holes for wall mounting, just below them there are control buttons and ports, which we will look at later. Here you can also see a lattice opening for ventilation.

Now let's look under the bottom of the ZXHN H118N stand. Password, MAC and IP addresses, firmware version, country of origin and other information are listed here. It is recommended to pay attention to these stickers, since some of the items listed will be needed to set up the device. Also, it is in the stand that there are hidden bolts that hold the case together.

How to download and install firmware on a router

If errors appear on the router, for example, during regular Wi-Fi shutdowns, for no apparent reason, the router can be reflashed. But this is done at your own peril and risk, since this will void the factory warranty. According to the MGTS agreement, the router belongs to the provider company, not the user. And in case of unsuccessful firmware, the user will have to pay the cost of the router.

In order to flash the router, you need to download the official version from the website of the equipment manufacturer ZTE, or contact MGTS technical support.

A few words about the manufacturer

The ZXHN H118N router is produced by the Chinese company ZTE, well-known in Russia. The domestic buyer may not even know that they belong to this brand, since providers, when purchasing devices for rent to the end user, stick on their logos. For example, “Dom.ru” icons are displayed both on the box and on the body of the router. But, undoubtedly, you need to know at least basic information about the manufacturer.

ZTE was founded in 1985. Engaged in the production of various types of communication devices (phones, tablets, modems, routers, etc.). The controlling stake is owned not by a private individual, but by the state. The products of this brand, in particular, routers, occupy leading positions in the budget segment. According to experts and users, they have the optimal balance of price and quality.

Common Problems

Saving readers' time, the thoughtful admin installed a plugin that draws convenient navigation according to the generated subheading tree. Therefore, we will devote a separate small section to each problem. ZTE primarily produces mobile modems, sometimes supplemented with a GPON fiber optic line interface.

Doesn't turn on

First of all, we remember whether the flashing was carried out. If unsuccessfully carried out manually, the operation completely removes access to the router. It is noteworthy that the appearance of the device (indication, backlighting of the Ethernet interface) is the same. However, it is impossible to connect a PC or equipment to the router. The browser writes: Unable to connect.

The hardware reset button is powerless to solve the problem. The firmware needs to be updated. Reputable manufacturers provide specialized utilities that help savvy technicians solve the problem. However, the Chinese manufacturer is keeping mum for now. Hackers have released the ZTE Unlocker utility, but the interface deals exclusively with the issue of unlocking (unlinking from a specific provider). The software actively exploits the diagnostic port specification.

A working device understands the terminal language, including the Windows command line. The operating system allocates a virtual directory to the device, within which commands stored in the router's memory are executed. For example, adb shell. However, standard management paths will refuse to help restore the firmware on the router. Enthusiasts offer the following option.

Sometimes the desire to unblock is caused by someone else. For example, the developer removed support for the FTTB protocol from the H108N model. All users of the interface were forced to immediately rollback. Only now... the manufacturer has released one utility that performs an upgrade. One way ticket.

Recovery utility

Often a broken ZTE modem is detected by the diagnostic interface. The official website (ztedevice) provides owners of MF30 (Beeline) exclusively with an update utility. There are no other models at all! The site 3ginfo.ru offers those who wish to download: “ZTE MF30 recovery kit”.

We disclaim liability by recommending this software. However, readers are free to try the effectiveness of the proposed measures themselves. We present an algorithm of actions according to the recommendations of the mentioned RuNet resource.

1. Install the ZTE Diagnostic Interface driver.
2. Unzip the downloaded recovery kit (firmware image).
3. Install the latest version of the QPST modem file system boot driver (2.7.323).
4. Launch the configuration dialog. Click the Add new port button of the QPST interface. Select the diagnostic one suggested by the operating system (see above).
5. If the utility is unable to detect what you need, manually open Device Manager (Windows) and look at the number of the COM port containing the diagnostic interface. Write the appropriate settings to the utility.
6. Launch QPST Software Download. Provide the program with the following basic information:

• Firmware port.
• Multi-image: location of the unpacked image file.
• Boot System: Multi Img 1.0.
• Advanced: if autodetection fails, check the firmware files.
• Trusted mode: check the box.

• Start the process with the Start button.
• The device will then reboot on its own, and Windows will begin installing the drivers.

Now the folder containing the previously unpacked firmware image needs correction. The software read the device memory, adjusting the contents of the internal directory. However, the utility is powerless to enter IMEI. Therefore, edit the Channel1.nvm file yourself. Please enter the correct IMEI.

Now run any flashing utility (for example, 3ginfo.ru/downloads127.html). Feed the program the files, including the edited Channel1.nvm. Now the router is finally restored.

A similar sequence of actions helps to revive some other mobile access points (for example, MF90).

It helps bring back life to many dead devices. Let's briefly describe the essence. In the 80s of the twentieth century, integrated circuit switching standards were deprived of a debugging interface. Therefore, in 1985, a special JTAG group was created to solve the problem. The industry standard became commercial (IEEE 1149.1-1990) in 1990. Intel immediately provided the 486 generation of processors with a debugging interface.

Now the standard is used by electronics manufacturers everywhere. Initially, the interface was solely for testing purposes. Then the opportunity became of interest to debuggers, including the machine code level. Later, manufacturers figured out how to exploit JTAG by updating the firmware of flash memory chips. Real boards use the number of pins:

The latter options are more often used when there are many parallel-connected microcircuits. The first option accompanies the star topology. Therefore, the problem is limited to calculating the pin layout of the JTAG port. Modern interfaces often contain 10 or more contacts, so take the trouble to find technical documentation that explains the meaning of the contact pads. The contacts themselves are round or rectangular in shape, often located along the edges, sometimes in two rows.

The pinout is difficult to find, since the subject is the bread and butter of repair shops. Try to puzzle thematic forums (for example, gsmforum.ru). You will also need a complete memory dump, take, for example, here 4pda.ru/forum/index.php?showtopic=255231&st=3040#entry36468746. The current memory dump (in reserve) is merged by the H-JTAG utility. You will need an adapter connector (the type is entirely determined by the utility used for recovery). Craftsmen usually adapt the now outdated LPT. Solder the adapter with shunt resistors, get specialized software (for example, Z_Flasher Reanimator is used to restore cellular USB modems).

A memory dump using the Giveio utility helps determine the processor type. This will be needed later when flashing. So, for work you need:

1. A utility for backing up the current memory dump.
2. Compatible modem firmware version. Try going to byfly. The FTP server provides a certain choice: H208N, ZXHN H208L, H201L, W300. By the way, the Belarusians took the trouble to post a beginner resuscitator kit, including instructions, in the shared server folder (ftp.byfly.by/byfly/firmware_modem/ZTE/).
3. Flashing utility via JTAG interface.
4. DIY connector. The utility sets detailed requirements for the adapter. An example of using LPT was given above.

Along the way, they exploit the capabilities of supporting software. For example, determining the type of processor.

Doesn't allow me to access settings

The live router is accessible via a browser or remote administration interfaces (TelNet, SSH). However, the admin panel does not launch inside. The factory settings have probably been changed. After making sure that you have the ISP password written down, try resetting the device with the Reset key (otherwise you will lose the Internet until your mother arrives). Then the previous equipment characteristics will return:

1. IP address.
2. Login.
3. Password.
4. SS >Refuses to distribute Wi-Fi
   Ukrtelecom subscribers have flooded the TP with complaints: ZTE H108L refuses to connect wireless subscribers. You will need to change your settings.
5. Open the admin panel (192.168.1.1 in the browser).

Enter your login/password (admin).

6. Click Administration → System Management → Restore Factory Settings.
7. Apply the changes and wait until you reboot.
8. Re-enter your ADSL connection login/password.
9. Set the following settings on the Administration → TR-069 page:

1. ACS URL – https://localhost
2. Login – loose
3. Password – 12345678

Reviews about the model

ADVANTAGES: Design, reliability, functionality DISADVANTAGES: The wi-fi setup could have been done better. The DSL device “raises” slowly, but holds the line well. Setting up the router did not cause any difficulties. Wi-Fi is also quite satisfactory - the ZTE ZXHN H208N reliably distributes it through a couple of walls and to 2-3 devices. The main precaution when working with a modem is that during a thunderstorm it must be disconnected not only from the electrical network, but also from the telephone line! If this is not done, when the clouds clear, you may find that the modem does not “see” DSL, or even shows no signs of life at all. How did this happen for us, by the way... :(( And the second important nuance - the design and specifics of operation of the ZTE ZXHN H208N, as, in principle, all modems with IMS support, provide for regular _automatic_ firmware updates. So if you are stuck Internet and ZALA, and when you approach the modem you see that the lights on it are blinking synchronously - three on the right, two on the left, if sclerosis does not change, touch the power button, let the device blink! Otherwise, you risk being left without the above-mentioned services until until the master comes and flashes the modem manually... :((

ADVANTAGES: Compact, efficient. DISADVANTAGES: connection via phone, little information on the Internet Not the most familiar design, but practical. The antenna will not be damaged and the signal transmission will not be lost in the apartment. It reaches neighboring apartments and works well. This is how it works day after day and has been working around the clock for over a year now. No complaints. We'll see what happens in the future, but for now there is no desire to change it. Dust:) Collects on horizontal surfaces.

This model suits me quite well. The Internet is fast enough, no problems have been noticed so far after a month of use. Of course, I’m not an expert, but it seems like a good router.

The ZTE ZXHN H208N device can be configured in the web shell in the Internet Explorer browser - in bridge or router mode. After setting up the Internet, set a long, complex password for the Wi-Fi network to protect your network from loss of traffic - no one will be able to enter your access point and waste your paid Internet.

ZTE routers are known to Russians. Megafon supplies subscribers with mobile options that cover exclusively the cellular network. Reception speed reaches 150 Mbit/s. The modem distributes wireless Internet. The portable option is often the choice of remote, relatively small settlements. Residents of Udmurtia are now familiar with the MR150-5. A region to the north of which there are only forests and tundra.

Chinese ZTE products are characterized by relatively low cost and availability. Even prisoners appreciated the benefits of 4G mobile communications. Recently, attackers tried to transfer 29 ZTE routers to the Tula colony. Valiant law enforcement officers managed to prevent the illegal transaction. Let's see exactly how to configure the router. Often the audience is interested in instructions for changing the password.

Checking the connection to the WiFi repeater

You need to make sure that the repeater works with the device. To check, enter the Wireless category Wireless Statistics. We see a list of equipment connected to the repeater.

The MAC address of this equipment is written here.

If the required device is not visible, but the Internet appears, it means it has connected to the main router. It is possible that the router software simply determined that the signal in this location from the base router is stronger. Move the main router with the access point further and try to connect again. If an attempt to connect to the repeater is unsuccessful, it means that the encoding type or password was entered incorrectly in the repeater’s security settings.

Port forwarding

It is often necessary to set up a home PC from the outside and organize a server. Network protocols use communication ports everywhere. The modem was originally designed with protection against hackers. Access inside (Intranet) is completely absent. Therefore, port availability needs to be configured. Let's demonstrate the technique of making adjustments using the example of H118N.

Note. The specified model shares Ethernet. The previous one (H108N) is equipped with two interfaces: FTTB, ADSL.

The simplest option to defeat Rostelecom hardware is to use the built-in Application menu. Activate the UPnP subkey. The port number is specified as a number. A little lower is a specialized section. The Port Forwarding menu will help you set the required numbers. Take the trouble to check the Enable box.

The third way is to set up a demilitarized zone. Creating a dedicated service helps limit the damage of a possible hacker attack. The settings are the same:

1. Connection type + port (in one line).
2. Local IP address of the PC.

Note. Sometimes translators call port forwarding redirection.

First check the functionality of the service provided externally within the network. Helps reduce setup time.

Unlock

It happens that sometimes a subscriber wants to change provider. I bought an MF823D, I was eager to switch to Iota, or I was tired of MGTS, and the F670 refuses to eat someone else’s SIM card. To change service provider, you must unlock the hardware. Megaphone MF823 is called M100-3 - the essence is the same. Unlocking is closely related to flashing issues. A provider-neutral binary image is selected.

Attention! Before installing the firmware, carefully study the forums. Some home-grown versions of the software partially break functionality. Example - H118NV2.0.1d_E04_OV DOMRU removes the web interface (via browser). Telnet access remains. I have to reflash it.

Instruction: Model MF823D

You will need a firmware image. Get it using search engines.

1. Download the PuTTY terminal emulator.
2. Install the ZTE diagnostic mode driver.
3. We turn on the equipment.
4. We feed the browser an intricate link 192.168.0.1/goform/goform_process?goform >The hardware should go into diagnostic mode. Check by opening Windows Task Manager. The properties contain the number of the serial port; opposite the corresponding COM there should be the inscription ZTE Diagnostic Interface.

Open a PuTTY terminal, copy the image to the serial port, the number of which is shown in the task manager. All that remains is to rescue the device from diagnostic mode. Open the terminal again, set the mode parameters:

The terminal window will be completely blank. Enter the commands one by one, pressing Enter each time:

Each time a device response may occur containing the number of successful and failed operations. The operation is completed. Reboot your device.
