A situation where in one part of the apartment or house the signal from the main router Rostelecom Many subscribers are familiar with the problem of the internet becoming unstable, and even disappearing completely in a distant room. Often, the standard coverage of the main device installed at the entrance or in the hallway is simply insufficient to penetrate thick walls and ceilings. A solution can be installing a second router that will receive the signal over the air and broadcast it further.
You don't have to run long Ethernet cables throughout your home unless absolutely necessary. Modern technology allows you to establish a wireless connection between two devices, creating a single network or expanding the coverage of an existing one. This is especially important for those who want to preserve the aesthetics of their interior and don't want to drill holes in their walls just to install a single cable.
However, the setup process requires care and an understanding of the basic principles of IP addressing. Incorrect configuration This can lead to address conflicts, which can cause internet access to stop even on the primary device. In this article, we'll walk you through a step-by-step process to turn an old or secondary router into a powerful receiver and signal booster.
Preparing equipment and selecting the operating mode
Before you begin setting up, you need to determine the operating mode of the secondary device. Most modern routers, whether Keenetic, TP-Link, Asus or Zyxel, support "Repeater," "Client," or "Bridge" (WDS) modes. In repeater mode, the device receives the signal, amplifies it, and distributes it further, often creating a single network with the same name (SSID).
Client mode allows the router to connect to the provider's network like a regular device (laptop or phone), and then distribute the Internet through its LAN ports or via Wi-Fi. It is crucial to find out in advance whether your specific router model supports WDS mode or the Repeater function without flashing alternative firmware. Some budget models from Rostelecom (for example, Sagemcom or Sercomm) may have limited functionality.
To get started, you'll need a computer or laptop connected to the router you're configuring via cable. Make sure you know the Wi-Fi password for your main router. Rostelecom, as it will be needed to pair the devices. It is also recommended to reset the secondary router to factory settings to eliminate the impact of old configurations.
The preparation process includes physical connection and checking the equipment's functionality. If the router was previously used as the primary router, it may still have PPPoE settings or a static IP address that will interfere.
⚠️ Important: Before starting setup, disconnect the ISP (WAN) cable from the main Rostelecom router if you plan to experiment with IP addresses to avoid conflicts on the local network.
Control interfaces may vary between manufacturers, but the logic remains similar. You'll need to log in to the web interface, find the wireless network section, and select the appropriate operating mode. In some cases, a firmware update may be required to enable the required features.
Changing the IP address of the secondary router
One of the most common mistakes when creating a network from two routers is an IP address conflict. By default, most devices have an IP address 192.168.0.1 or 192.168.1.1If both routers have the same address, the network will not work.
To begin, connect your computer via cable to the LAN port of the router you're configuring (leave the main port alone for now). Access the control panel by entering the address on the sticker on the bottom of the device into your browser. Go to the LAN settings section. Here, you'll need to change the last digit of the IP address.
For example, if the main router Rostelecom has an address 192.168.1.1, then the secondary device needs to be assigned an address 192.168.1.254 or 192.168.1.2The main thing is that the address is in the same subnet, but does not coincide with the default gateway.
☑️ Check before changing IP
After changing the IP address, the router will prompt you to reboot. Your computer will lose connection, and you'll need to log in to the control panel again using the new address. This is normal system behavior.
It's also important to check the DHCP server settings on the secondary device. In repeater or bridge mode, this server often needs to be disabled so that only the primary router is responsible for distributing addresses. RostelecomIf DHCP remains enabled on both devices, devices on the network will receive incorrect gateway settings.
Setting up a wireless bridge (WDS) or repeater mode
The most efficient way to connect two routers over the air is using WDS (Wireless Distribution System) technology or the built-in Repeater feature. Unlike a simple client connection, WDS allows data to be transmitted between access points transparently to all devices on the network.
In the secondary router's menu, find the "Wireless" section and enable WDS. Once enabled, a "Survey" button will appear. Click it to have the device search for networks within range.
In the list of found networks, select the SSID of your main router RostelecomThe system will automatically fill in the MAC address and channel. All you need to do is select the encryption type (usually WPA2-PSK) and enter the password for your main Wi-Fi network.
What to do if WDS is not working?
The WDS feature is non-standard, and different manufacturers implement it differently. Routers from different brands (for example, TP-Link and Asus) may not work together via WDS. In this case, it's best to use Client or Wireless Bridge mode, if supported, or update your router to OpenWRT.
After saving the settings, the wireless network indicator on the secondary router should light up or change color, indicating a successful connection. If this doesn't happen, check that the channels on both devices match. For stable WDS operation, it is recommended to manually set a static channel (e.g., 1, 6, or 11) on both routers, disabling automatic channel selection.
Keep in mind that speed may decrease in repeater mode, as the radio module operates in half-duplex mode: it cannot simultaneously receive and transmit data on the same frequency. Using dual-band routers (2.4 GHz and 5 GHz) minimizes this effect by using one band for communication between routers and the other for distributing data to clients.
Configuration of DHCP and LAN parameters
Properly setting up your local network is the key to a stable internet connection. As mentioned earlier, the secondary router should not conflict with the primary router. Ensure that the DHCP address range on the secondary device is either disabled or outside the range of the primary device.
For example, if the main router distributes addresses from 192.168.1.100 to 192.168.1.200, then it's best to completely disable DHCP on the secondary device. In this case, all devices connecting to the second router will receive IP addresses from the main gateway. Rostelecom.
If you're using a mode that requires DHCP, configure it so it doesn't interfere with the main pool. This is a complex configuration that's rarely needed, usually for network segmentation.
Check the subnet mask. It should be the same on both devices; the default value is 255.255.255.0An error in this setting will result in devices from the same subnet not being able to "see" each other.
It's also worth paying attention to DNS servers. It's best to set up automatic DNS retrieval from your provider or specify public addresses, such as those from Google (8.8.8.8) or Yandex (77.88.8.8) to avoid name resolution problems.
Comparison of router operating modes
Understanding the differences between operating modes will help you choose the best option for your situation. Below is a table comparing the key features of the modes available on most modern devices.
| Parameter | Repeater | Access point (AP) with cable | Client Mode |
|---|---|---|---|
| Connection method | Via Wi-Fi | Via Ethernet cable | Via Wi-Fi |
| Stability | Average (depending on signal) | High | High (for wired devices) |
| Speed | Reduced to 50% | No losses | No loss for LAN ports |
| Difficulty of setup | Average | Low | High |
As the table shows, if it's technically feasible to install a cable, access point (AP) mode is the best choice. However, when cable installation is not feasible, repeater mode becomes the only solution.
Client mode is often used to connect devices without their own Wi-Fi module (such as Smart TVs or game consoles) to a wireless network. In this case, the router receives the Wi-Fi signal and distributes it through the LAN port.
Optimizing and selecting a Wi-Fi channel
After successfully connecting the two routers, it's important to optimize the radio channel. In apartment buildings, the airwaves are clogged with signals from neighboring networks, causing interference and speed drops.
Use Wi-Fi analysis apps (eg. WiFi Analyzer (on Android) to find the least crowded channel. For the 2.4 GHz band, it is recommended to use only channels 1, 6, and 11, as they do not overlap.
Set the same channel on the primary and secondary routers. The channel width must be fixed: 20 MHz for maximum stability in noisy air or 40 MHz for speed, if there are few neighbors nearby.
Don't forget about transmitter power. If the routers are close to each other, reducing the power can reduce mutual interference. If the distance is great, set the power to maximum.
For the 5 GHz range, channel selection is less critical, since there are more free frequencies, but the signal range is significantly smaller and it penetrates walls worse.
Problem solving and diagnostics
Even with proper configuration, problems may still occur. If devices connect to the secondary router but there's no internet, check the WDS connection status. The LEDs on the router usually indicate a connection to the primary node.
A common problem is "looping," where the device constantly reconnects. This can be caused by a weak signal from the primary router at the repeater's installation location. Try moving the secondary router closer to the signal source.
Also, check your security settings. The encryption type and password must match on both devices. Some older devices do not support the modern WPA3 encryption standard, which may require downgrading to WPA2.
⚠️ Note: Settings interfaces and menu item names may vary depending on the router's firmware version and model. If you cannot find the item described, please refer to the manufacturer's official documentation or support website.
If all else fails, perform a full reset on the secondary router and repeat the setup process again, carefully checking each step. Sometimes, temporarily disabling MAC address filtering on the primary router for diagnostic purposes can help.
In some cases, the problem may stem from incompatibility between equipment from different manufacturers. If setting up a bridge fails, consider purchasing a specialized mesh system designed for seamless network expansion.
Is it possible to connect a Rostelecom router to a router from another manufacturer?
Yes, it is possible, but WDS (wireless bridging) mode is a non-standard technology. Routers from different brands (for example, TP-Link And Asus) may not be able to see each other in bridge mode. In such cases, it's more reliable to use Client or Repeater mode, if supported by both devices, or connect them with a cable.
Why does internet speed drop through a second router?
When using a wireless connection (repeater), speed is often halved because the radio module alternates between receiving and transmitting data. Distance, the number of walls, and airborne noise also play a role. Using a cable or dual-band routers (5 GHz connection, 2.4 GHz distribution) helps minimize losses.
Do I need to enter my Rostelecom login and password on the second router?
No, in repeater, bridge, or access point mode, the second router does not perform authentication with the ISP. These settings (PPPoE, Login, Password) are only needed on the main router, which is directly connected to the ISP's line. The second router simply extends the existing local network.
How do I reset my settings if I'm confused about the settings?
There is a button on the body of any router. Reset (often recessed into the case). With the power on, press it with a thin object (like a paperclip) and hold for 10-15 seconds until the indicators flash. After this, the device will reset to factory settings, and you can start setup again using the information on the sticker on the bottom.
