How to extend your Wi-Fi network with a second ZTE router

The situation where the main router's signal fails to reach distant rooms or penetrates thick concrete walls is familiar to many home internet users. Instead of purchasing an expensive mesh system or running long cables, using an old or spare router is often an effective solution. ZTE as an access point. This not only increases coverage but also allows you to connect more wired devices via LAN ports.

Setup process secondary router This process requires attention to detail, especially when working with IP addresses and the DHCP server. An error at any stage can lead to network conflicts, which will result in the internet being down on all devices. However, by following a clear sequence of steps, you can connect two devices into a single local network in minutes.

In this article we will look at a universal method that is suitable for most models. ZTE, including the popular F660, F670, and AX series routers. We'll cover the physical connection, web interface login, and proper configuration to ensure your second router becomes a fully functional extension of your main network, rather than a problem.

Equipment preparation and compatibility testing

Before you begin working with the software, you need to ensure that your hardware is physically ready. You'll need a primary router that already distributes internet, and a second router. ZTE, which will operate in access point mode. It is desirable that both devices support the standard 802.11ac or higher, so that the wireless data transfer speed does not drop critically.

Be sure to check the presence of a network cable Ethernet (twisted pair). It's best to use Category 5e or Category 6 cable to connect two routers, as they provide stable gigabit speeds. If the cable is old or damaged, setup may be successful, but the actual internet speed will be slow or unstable.

⚠️ Important: Make sure you know the login and password for the main router's administrative panel, as we may need to find out the connection type or reserve a static IP address.

It's also important to understand the difference between operating modes. We'll be setting up Access Point mode, in which the second router simply broadcasts the signal, while the main device distributes IP addresses. This prevents the creation of "double NAT," which is critical for online gaming and some smart home apps.

Don't forget to reset the second router ZTE to factory settings before starting. This will prevent conflicts with old configurations. To do this, press and hold the button Reset on the back panel for 10-15 seconds until the indicators flash simultaneously.

Physical connection diagram of devices

A proper cable connection is the foundation for a stable network. Unlike setting up a router as the primary connection, here we'll use LAN ports on both devices. Connect one end of the cable to any available LAN port on the main router, and the other end to the router's LAN port ZTE.

Important: Do not use the port WAN (or Internet) on the second router ZTE With this connection scheme, if you configure it manually by disabling DHCP. Using the WAN port is only possible if the firmware has a dedicated mode switch, but the classic method requires a LAN-to-LAN connection.

• 🔌 Take an Ethernet patch cord and insert it into the yellow LAN port of the main router.
• 🔌 Connect the other end of the cable to any LAN port on the router ZTE (usually they are also yellow).
• 💻 Connect your computer or laptop to any other LAN port on the router ZTE for customization.
• 🔋 Make sure both routers are plugged into a power outlet and the power indicators are on.

After turning on the LAN indicator on the router ZTE The indicator should light up or start blinking, indicating physical contact between the devices. If the indicator doesn't light up, check the cable's integrity or try a different port.

Logging into the ZTE router web interface

To begin configuration, you need to access the control panel. Open any browser on the connected computer and enter the router's default IP address in the address bar. ZTEMost often it is 192.168.1.1 or 192.168.0.1The exact address is indicated on the sticker on the bottom of the device.

The system will request authorization. The default credentials are also on the label: usually, this is the login admin and password admin (or a unique password provided by the manufacturer). If you have changed the password previously and do not remember it, a full reset will be required using the button Reset.

Interfaces ZTE may differ depending on the firmware version and carrier (for example, Rostelecom versions have a modified design). However, the menu structure is generally the same: look for sections Network, LAN or Local Network.

⚠️ Note: If the page doesn't open after entering the correct IP address, check your PC's network card settings. It should receive an IP address automatically (DHCP mode).

In some modern models with Wi-Fi 6 support, you can log in using a domain name, for example zte.home or my.zte, but using a digital IP address remains the most secure way to access the admin panel.

Changing the IP address of a local network

This is a critical step. By default, both routers may have the same IP address (e.g. 192.168.1.1), which will cause a conflict and crash the network. You need to change the IP address of the second router. ZTE so that it is in the same subnet as the main one, but does not coincide with it.

Find the section in the menu LAN or Network SettingsIn the field IP Address Change the last digit. If the address of the main router 192.168.1.1, then ask the second one 192.168.1.2 or 192.168.1.254The main thing is that the first three digits (subnet) match.

After changing the IP address, the router will prompt you to reboot or automatically redirect you to the new address. You'll need to enter the new IP address in your browser again to continue setup. Remember or write down the new address, as you'll need it for future management of this device.

• 📝 Go to the menu Network → LAN Settings.
• 📝 Find the field IP Address and change the host part (the last number).
• 📝 Make sure the subnet mask (Subnet Mask) is set to the value 255.255.255.0.
• 📝 Save the settings with the button Apply or Save.

If you don't change the IP address, you won't be able to control both devices at the same time, and in the worst case, one of them will block the other's network traffic.

Disabling the DHCP server

Only one IP address-distributing server can operate on any network. Since this role is performed by the primary router, the second router ZTE function DHCP Server It must be forcibly disabled. Otherwise, devices will receive incorrect gateway settings and will not be able to connect to the internet.

In the LAN settings menu, find the subsection DHCP ServerThere will be a check mark or a switch in the position EnableYou need to choose Disable or uncheck the box. After applying the settings, the router will stop issuing addresses.

From now on, your computer connected to the router ZTE, will receive an IP address from the main device. This means that your PC's IP address may change, and connection to the second router's admin panel may be temporarily interrupted until the page is refreshed.

⚠️ Attention: After disabling DHCP and saving the settings, access to the router interface ZTE is only possible using the new static IP address you specified in the previous step.

Make sure you save the settings. Some firmware versions require a separate button press. Save/Apply after each change, in others, the changes take effect immediately after switching the toggle switch.

Configuring Wi-Fi wireless network settings

Now you need to configure the radio module. You can create a new network with a unique name or clone the main network settings to create seamless (or pseudo-seamless) coverage. For user convenience, it's best to use the same settings. SSID (network name) and password, but on different channels.

Go to the section WLAN or WirelessIn the field SSID Name Enter the desired network name. If you want phones to switch between routers automatically, the name and password must match the primary router. However, the broadcast channels must be different to avoid interference.

For the 2.4 GHz band, it is recommended to use channels 1, 6, or 11. If the main router operates on channel 1, assign the second router to channel 6 or 11. For the 5 GHz band, select channels that do not overlap with neighboring networks.

• 📡 Turn on the wireless module (Enable Wireless).
• 📡 Set the network name (SSID) identical to the main one or new.
• 📡 Select the type of protection WPA2-PSK or WPA3 for maximum safety.
• 📡 Set a complex password containing letters and numbers.

Don't forget to save the settings. After that, the router ZTE will begin broadcasting a Wi-Fi signal. Devices will see the network and connect to it, receiving internet via a cable from the main router.

Table of recommended IP and channel settings

For ease of setup, we'll provide an example of a correct configuration for a two-router setup. This information will help you avoid confusion when entering parameters.

Use this table as a checklist when entering data into the web interface. Any deviation, especially in the DHCP section, may result in network inoperability.

Diagnostics and troubleshooting

After completing the setup, you may encounter situations where the internet doesn't appear or the speed remains slow. First, check whether the device connected to the second router is receiving an IP address from the primary router's range. If the address begins with 169.254.x.x, then DHCP is not working or the cable is faulty.

A common problem is a "loop" or improper connection to the WAN port. Make sure the cable runs from the primary router's LAN to the secondary router's LAN. Also, check that the primary router's antivirus or firewall isn't blocking new devices.

If your Wi-Fi speed is low, it's possible the channels are too busy with neighboring networks. Use Wi-Fi analyzer apps on your smartphone to find a free channel and manually enter it in the settings. ZTE.

⚠️ Note: Firmware interfaces may be updated by the manufacturer. The layout of menu items may differ slightly from that described. Please look for similar names.

In case of complete loss of access to the settings of the second router, use the button Reset to reset to factory settings and start the procedure again, carefully checking each step.

Customization features for different ZTE models

Equipment line ZTE is extensive, and firmware may differ. In older models, such as ZXHN H108N, the menu can be simpler and more ascetic. Here it is important to find the section LAN and pay close attention to the field DHCP Service.

In more modern models with support GPON or FTTH (fiber optic) routers, which are often provided by ISPs, may have a blocked or simplified interface. If you don't see an option to disable DHCP, your model may only operate in router mode, and creating an access point will require a firmware update or special commands.
