Expanding wireless network coverage often becomes necessary in large apartments or private homes where standard provider equipment is not up to the task. Connecting an additional router Connecting a cable to the main Rostelecom device eliminates dead zones and ensures a stable signal in even the most remote rooms. This process requires attention to detail, but is easily accomplished independently if you follow the correct steps.
There are several proven methods of connecting equipment: wired connection via LAN-WAN or LAN-LAN, as well as the creation of a wireless bridge WDSThe choice of a specific method depends on the architecture of your home, the availability of existing cables, and the technical specifications of your devices. In this article, we'll detail the most reliable setup options that guarantee a seamless network.
Before you start physically connecting the devices, you need to prepare main router (which already distributes Internet from Rostelecom) and secondary device (which will amplify the signal). It's important to understand that the secondary router will work in conjunction with the primary router, receiving traffic from it and forwarding it further. It is critically important to reset the secondary router to factory settings before starting work to avoid IP address conflicts.
Preparing equipment and resetting settings
The first step in integrating new equipment is to clean the secondary router. Even if the device is new, its memory may still contain factory test configurations or data from previous use. To do this, locate the button on the device's housing. Reset or WPS/ResetIt is usually recessed into the body, so you will need a paperclip or a thin needle to press it.
Hold the button down for about 10-15 seconds while the device is powered on. The indicators on the front panel should blink or turn off, indicating the recovery process has begun. After the reboot, the device will return to the default settings indicated on the sticker on the bottom of the case.
⚠️ Attention: After resetting the settings, the secondary router's web interface will be accessed via the IP address listed on the factory label (often 192.168.0.1 or 192.168.1.1). Make sure this address doesn't match the address of the primary Rostelecom router, otherwise a conflict will occur.
Now you need to physically connect your computer to the secondary router for the initial setup. Use an Ethernet cable, plugging one end into either LAN-port of the router, and the other to the PC's network card. At this point, the computer's internet connection may temporarily be lost, as the device hasn't yet been configured to work with the ISP.
☑️ Check before setup
Setting up the secondary router's IP address
After connecting to the secondary device's interface, you need to change its network address. This is a mandatory procedure, as both routers cannot have the same IP address on the same network. If the primary Rostelecom router has the address 192.168.1.1, then the secondary one needs to be assigned, for example, 192.168.1.2 or change the subnet to 192.168.2.1.
Log in to the web interface by entering the default address in your browser. Go to the section Network (Network) or LAN Settings (Local Area Network Settings). Find the field IP Address and change the last digit of the address. It is also recommended to check the settings DHCP ServerIn most connection schemes, the secondary router must operate in access point mode, so it's best to disable the DHCP server on it so that the main router handles address distribution.
Save the changes. After this, the router will reboot, and you'll need to use the new IP address to access its settings in the future. Don't forget to reconfigure your computer's network card to obtain an IP address automatically if you changed these settings manually.
Changing the address helps avoid confusion when managing your network. You'll always know which address leads to your provider's main gateway and which to your additional expansion node. This is especially useful for troubleshooting connection issues in different parts of your home.
LAN-WAN connection diagram (Cascade)
One of the most popular methods of combining routers is the scheme LAN-WANIn this case, the cable is laid from any LAN-port of the main Rostelecom router to the port WAN (or Internet) of the secondary device. This topology creates two separate subnets, which can be useful for traffic segmentation.
To implement this method, make sure that the connection type is selected in the WAN settings on the secondary router Dynamic IP (Dynamic IP). This will allow it to automatically obtain an address from the main router. The physical connection is made via a standard patch cord, which must be long enough to be installed between rooms.
- 🔌 Connect the cable from the LAN port of the main router to the WAN port of the second one.
- ⚙️ In WAN settings, select the "Dynamic IP" mode.
- 📡 Set up the Wi-Fi network name (SSID) and password on the second router.
- 💾 Save the settings and reboot your device.
The advantage of a LAN-WAN setup is the isolation of devices connected to the second router. They will be on their own subnet, which improves security, but may complicate access to shared resources, such as network printers or media servers, located on the main router's network.
LAN-to-LAN connection diagram (Access Point Mode)
A more preferable option for creating a unified space is a scheme LAN-LANIn this mode, the secondary router functions solely as a switch and access point, without creating a separate subnet. All devices in the home will be able to see each other, which is convenient for setting up a local network.
The key here is to disable the function DHCP Server On the secondary router. Only the primary Rostelecom router should handle address distribution. Leaving DHCP enabled on both devices will cause network conflicts, and the internet will stop working on some devices.
The physical connection in this circuit is made from LAN-port of the main router in LAN- secondary port. The WAN port on the secondary router remains free. Once connected, computers and smartphones will automatically switch between access points (roaming), although with slight delays, as full mesh roaming will not be possible here.
| Parameter | Main router | Secondary router |
|---|---|---|
| Opening hours | Router | Access point (AP) |
| DHCP Server | On | Disabled |
| IP Address | 192.168.1.1 | 192.168.1.2 |
| Connecting the cable | LAN port | LAN port |
Using access point mode maximizes the efficiency of the provider's primary equipment. The secondary device handles only the radio module and switching, offloading routing tasks from the main router's processor.
Wireless bridging (WDS)
If laying cables between rooms is not possible, you can use the technology WDS (Wireless Distribution System). It allows routers to be connected over the air, transmitting internet signals wirelessly. However, this method is susceptible to interference and requires both devices to support this feature.
WDS configuration is done in the wireless settings section. WirelessOn the secondary router, enable the bridge function and scan for available networks. Select the network of the primary Rostelecom router and enter the security key. It's important that the channels and encryption types on both devices match.
⚠️ Attention: When using a wireless bridge, the internet speed on the second router may drop to 50% of the actual speed due to the specific operation of the radio channel in repeater mode.
Why does the speed drop in WDS mode?
In bridge mode, the secondary router's radio module is forced to simultaneously receive the signal from the primary router and transmit it to client devices. Since it operates on the same frequency, it cannot do both simultaneously and must switch between receiving and transmitting, resulting in a drop in throughput.
For stable WDS operation, it's recommended to install the secondary router within a strong signal range of the primary router. Walls and appliances can significantly weaken the signal, so a hallway or open space between rooms is ideal.
Wi-Fi network setup and security
Once the routers are successfully connected, you need to configure the wireless network settings. For ease of use, it is recommended to set the same network name (SSID) and a password on both devices. This will allow smartphones to automatically switch to a stronger signal as you move around the house.
However, it is worth considering that without technology support Mesh Devices can "catch" a weak signal from a distant router, even when they're close to the main one. In this case, you can give the networks different names, for example, Home_Wifi And Home_Wifi_Extto manually control the connection.
Be sure to choose a modern encryption standard. WPA2-PSK or WPA3Using outdated security protocols makes your network vulnerable to hacking. Passwords should be complex and contain letters and numbers.
It also makes sense to change the broadcast channel on the secondary router if it's located near the primary one to avoid interference. For example, if the primary router operates on channel 1, the secondary router can be assigned channel 6 or 11 in the 2.4 GHz band.
Diagnostics and troubleshooting
During setup, you may encounter situations where devices don't see each other or the internet isn't working. First, check the indicators on the router housings. If the indicator is lit, WAN or Internet on the secondary device usually indicates that there is a physical connection.
If you don't have internet access, try running the command ping to the gateway address. This will help determine where the network break occurred. Also, make sure the secondary router's MAC address isn't blocked in the parental controls or filtering settings of the primary device.
- 🔄 Reboot both routers one by one: first turn off the main one, then the secondary one, turn on the main one, wait for it to boot up, then turn on the secondary one.
- 🔍 Check the integrity of the Ethernet cable by connecting the computer directly through it.
- 🛡️ Make sure the firewall on the secondary router is not blocking WAN requests.
A common problem is incompatibility between devices from different manufacturers. Some firmware may not work correctly with devices from other brands. In this case, updating the software (firmware) to the latest version may solve the problem.
What to do if the secondary router does not distribute IP addresses?
Most likely, the secondary router's DHCP server is still enabled, or it's conflicting with the primary router. Go to the secondary router's LAN settings and force-disable DHCP. Make sure its IP address is in the same subnet as the primary router, but not the same.
Is it possible to connect routers from different manufacturers?
Yes, Ethernet and Wi-Fi standards are universal. You can connect a Rostelecom router to a TP-Link, ASUS, Xiaomi, or any other device. The main thing is to correctly configure the IP addresses and operating modes (LAN-WAN or LAN-LAN).
Will my internet speed decrease when I connect a second router?
With a wired connection (LAN-to-LAN or LAN-to-WAN), speed losses are minimal and unnoticeable in everyday use. With a wireless bridge (WDS), speed can drop by up to 50% due to the specifics of the radio channel.
Do I need to configure PPPoE on the second router?
No, PPPoE setup (provider login and password) is performed only by the primary router. The secondary device receives an existing internet connection and simply forwards it, so the "Dynamic IP" mode is selected in its settings.
