How to connect a router via Wi-Fi and configure it as an access point

Converting an old or spare router into an access point is one of the most effective ways to expand your home wireless network's coverage without purchasing expensive mesh equipment. Instead of creating isolated subnets with different IP addresses, you unite devices into a single ecosystem where devices seamlessly switch between them. This solution is ideal for large apartments where the main router's signal doesn't reach distant rooms, or for densely populated office spaces.

The main advantage of this approach is maintaining a single namespace for all devices. Printers, smart lamps, and TVs will see each other regardless of which device you're currently connected to. Setup takes no more than 15-20 minutes, and the result dramatically improves connection stability in "dead zones."

Unlike repeater mode, which often cuts speed in half, Access Point mode allows you to use the wired link between routers to transmit data at full speed, leaving the airwaves free for clients. If wiring isn't possible, modern models also support wireless bridging, although stability in this case depends on the quality of the radio channel. Let's examine the process in detail to avoid common pitfalls.

Preparing equipment and selecting a connection diagram

Before setting up, you need to decide on the physical connection method for the two devices. The classic setup involves using an Ethernet cable running from the primary router (which distributes the internet) to the secondary router (which will act as the access point). This ensures maximum speed and stability, as traffic between nodes doesn't compete with user traffic over the air.

If wiring is not possible, many modern routers, such as Keenetic or TP-Link with technology support OneMesh or AiMesh, allow you to establish a wireless connection. In this case, the secondary router receives the Wi-Fi signal and distributes it further. However, it's worth keeping in mind that in wireless bridging mode (WDS or Bridge), the actual channel throughput may decrease.

⚠️ Important: Make sure your secondary router supports Access Point mode. Budget models may not have this feature built-in, requiring you to use WDS mode, which is more difficult to configure and less stable.

To work you will need:

• 🔌 The main router, already configured and distributing the Internet.
• 📡 A second router (configurable), preferably of the same or compatible series.
• 🖥️ A computer or laptop with a network card for initial setup.
• 🔗 Patch cord (Ethernet cable) for connecting a PC to a router or routers to each other.

It's also important to check the firmware versions on both devices. Manufacturers regularly release updates that fix security vulnerabilities and improve wireless module performance. Visit your brand's official support page and compare the current version with the latest available one.

Reset settings and enter the control interface

Before changing the configuration, the secondary router must be sterilized. This will prevent IP address conflicts and any leftover settings from the previous owner or ISP. Locate the button on the device. Reset (often it is combined with the power button or hidden in a recess).

Press the button with a thin object (a paperclip or toothpick) and hold it for 10-15 seconds until the indicators flash simultaneously. After this, the device will reboot to factory settings. Connect the computer to any LAN port (but not WAN/Internet) of the secondary router using a cable.

Open your browser and enter the web interface address. By default, this is usually 192.168.0.1, 192.168.1.1 or a domain name like tplinkwifi.netThe exact address is indicated on the sticker on the bottom of the device. If the page doesn't open, check your PC's network adapter settings—they should be set to "Obtain an IP address automatically."

When you log in, you will be asked to create an administrator password. Don't ignore this step., leaving the field blank or using the default admin/adminThis is your local network's first line of defense against unauthorized access. Write down the new password in a safe place.

Configuring IP addresses to avoid conflicts

One of the most common mistakes is leaving the same IP addresses on the primary and secondary routers. If both devices have an address, for example, 192.168.0.1, the network will crash, and you'll lose access to both devices. Therefore, the first step is to change the LAN IP address of the secondary router.

Go to the section Network → LAN (or similar depending on the model). Change the last digit of the address to a unique one, for example, 192.168.0.254 or 192.168.0.2The main thing is that the address is in the same subnet as the main router, but not the same and not included in the range of addresses issued by the main device's DHCP server.

After changing the IP address, the router will prompt you to reboot. You'll need to enter the new address in your browser to continue using it. Make sure you remember the new address, as it will be used to manage this access point.

Disabling the DHCP server on the secondary device

This is the most critical configuration step. Any local network can only have one active DHCP server, which assigns IP addresses to connecting clients. Leaving it enabled on the second router will cause chaos: devices will receive incorrect gateway or DNS addresses, resulting in no internet connection.

Find the section DHCP or LAN Settings in the secondary router's menu. Select the option Disable (Disable) or OffSave the settings. Now all requests for an IP address will be ignored by this device and processed exclusively by the main router.

⚠️ Caution: After disabling DHCP and saving the settings, you may lose connection to the secondary router's web interface if your computer attempts to obtain a new address. In this case, manually assign a static IP address to your PC's network card in the same subnet.

Your secondary router has now become a simple switch with Wi-Fi functionality. It's no longer a standalone router but a transparent bridge. All devices connected to it will be on the same network as computers connected to the primary router.

Wi-Fi wireless network configuration

To create a unified network (roaming) effect, you need to configure your wireless settings correctly. Go to the section Wireless or Wi-Fi SettingsHere you need to set the network name (SSID) and password.

There are two naming strategies:

• 📶 Same name and password: Set the exact same SSID and password as your main router. Devices will see the same network and automatically switch between access points depending on signal strength. However, the switch may not happen instantly.
• 🆔 Different names: Name the network, for example, Home_Wifi_ExtThis will allow you to manually select which access point to connect to, which is sometimes more convenient for stationary devices (TVs, printers) to "bind" them to a specific router.

It's important to select the correct channel and channel width. If the primary router operates on channel 1, it's recommended to set the secondary router to channel 6 or 11 (for the 2.4 GHz band) to avoid overlapping. For the 5 GHz band, you can leave it on auto-selection, but manually separating the frequencies is better.

Why does the speed drop even with the same network name?

Standard client devices (smartphones, laptops) often cling to an access point until the very end, even if the signal is already very weak, instead of switching to a nearby one. This is called a "sticky client." This can only be resolved by setting a minimum signal threshold for disconnection or using mesh systems with 802.11k/v/r support.

Don't forget to choose a modern security standard. Use WPA2-PSK (AES) or WPA3, if all your devices support the new protocol. Avoid outdated TKIP or WEP encryption, as they are easily cracked and limit connection speed.

Physical connection and final check

Once the software setup is complete, it's time to put the system together. Take an Ethernet cable, with one end connected to LAN port main router. Connect the other end of the cable in the same way LAN port secondary router.

Critical: Do not connect the cable to the WAN (Internet) port of the secondary router unless you are using the special "Access Point" mode, which reprograms this port. The classic setup (with DHCP disabled) uses only a LAN-to-LAN connection.

After connecting the cable, wait for the indicators to load. The computer connected to the secondary router should receive an IP address from the primary router. Check internet access and try pinging devices connected to the primary router.

If everything is configured correctly, you'll get a unified network with extended coverage. Speeds in distant rooms will increase, and dead zones will disappear. To check the signal quality, you can use apps like Wi-Fi Analyzer on a smartphone while walking around the apartment.

What should I do if the internet disappears on all devices after setup?

Most likely, there's an IP address conflict, or you connected the cable to the WAN port instead of the LAN port. Disconnect the cable between the routers. Log into the primary router and check the client list. If a device with an address outside the DHCP range appears, the secondary router is still distributing addresses. Reset it using the Reset button and repeat the procedure, making sure to disable the DHCP server.

Is it possible to connect routers via Wi-Fi without a cable?

Yes, this is possible using WDS Bridge or Wireless Bridge mode. However, in this mode, the speed is cut almost in half, since the radio module operates both for receiving and transmitting. Furthermore, WDS often requires both routers to be from the same manufacturer. For more complex tasks, it's better to use PowerLine adapters or extend a cable.

Do I need to set up a second router if I purchased a Mesh system?

No. Mesh systems (e.g., TP-Link Deco, Keenetic with KeeneticOS, Asus AiMesh) are configured automatically. The main node automatically distributes settings to the satellites. Manually configuring IP and DHCP on mesh nodes may disrupt the network's self-healing algorithms.
