The situation where the Wi-Fi signal stops reaching a distant room or the kitchen is familiar to many owners of apartments with thick walls or complex layouts. Purchasing new, expensive equipment or a mesh system isn't always budget-friendly, especially if you have an old, but working router lying around. Using a second router as an access point is a time-tested way to expand your network coverage without unnecessary expense or loss of connection quality.
Unlike repeater mode, which often cuts speed in half, a wired connection of a second device provides a stable data transmission channel. Access point It simply broadcasts the signal from the main router, creating a unified logical network in which all devices can see each other. This allows for seamless file transfers between computers, use of network printers, and video streaming to TVs anywhere in the home.
In this article, we'll take a detailed look at how to turn any modern router into an effective network extender. You'll learn the intricacies of configuring IP addresses, disabling the DHCP server, and properly setting up a physical connection. TP-Link, Asus, Keenetic or Mikrotik — the setup principles are universal, although the interfaces may differ.
Get ready to work with network interfaces to turn your home into a seamless coverage area.Why you need a second router and the benefits of a wired access point
The main reason for using additional equipment is the physical limitation of the radio signal. Walls, mirrors, household appliances, and even aquariums absorb or reflect radio waves, creating "dead zones." Repeaters Repeaters solve this problem, but often create a separate subnet or significantly reduce channel throughput. A cable-connected access point avoids these drawbacks.
When you configure a second router as an access point, you essentially create an extender for your LAN port. The internet speed on the remote device will be limited only by the capabilities of the cable and the router itself, not by wireless transmission losses. This is critical for 4K video, online gaming and video conferencing, where ping and jitter play a decisive role.
- 🚀 Maximum speed: The cable connection ensures full throughput without the losses typical of a wireless bridge.
- 🏠 Single space: All devices are on the same subnet, which simplifies data exchange and smart home management.
- 📡 Stability: A wired connection is not susceptible to interference from neighboring networks and microwave ovens, unlike WDS bridges.
Additionally, older routers often have more powerful antennas or support standards that aren't supported by your ISP's default modem. For example, if your ISP gave you a simple box with a single antenna, and you have an older dual-band router, Zyxel, you can use its potential to relieve airspace congestion in the 5 GHz frequency range.
⚠️ Attention: To implement this setup, you must be able to run an Ethernet cable (twisted pair) from the primary router to the second device. Without a physical cable connection, configuring the "Access Point" (LAN-to-LAN) mode is impossible; you'll need WDS or Client mode, which operate differently.
Equipment preparation and connection diagram
Before tweaking the interface settings, you need to properly prepare the hardware. You'll need two routers: the primary one (which already distributes the internet) and the secondary one (which will act as an access point). You'll also need a piece of network cable. UTP Cat5e or longer, the length of which is sufficient to connect the devices.
It's important to understand the port logic. In access point mode, we'll only use LAN ports on both devices. Port WAN The (Internet) port on the second router in this setup is typically left unused, as we're converting the router into a Wi-Fi switch. This is a key point that beginners often miss when trying to connect a cable to the "blue" port.
☑️ Check before setup
The connection diagram looks like this: a cable from the ISP enters the WAN port of the primary router. From any LAN port on the primary router, the cable goes to the LAN port of the secondary router. Computers and TVs are connected to available LAN ports on the secondary device or via Wi-Fi. Thus, IP address distribution (DHCP) is entirely the responsibility of the primary router.
| Parameter | Main router | Second router (Access point) |
|---|---|---|
| IP address | 192.168.0.1 (example) | 192.168.0.2 (static) |
| DHCP Server | On | Turned off |
| Connecting the cable | LAN port | LAN port |
| Wi-Fi name | Home_Net | Home_Net (or Home_Net_5G) |
Setting an IP address and disabling DHCP
The most important step is configuring the network settings of the second router. Connect your computer to any LAN port of the secondary device (don't connect it with a cable from your ISP yet!). Log in to the web interface by entering the address on the sticker at the bottom (usually 192.168.0.1 or 192.168.1.1). If the primary router's address matches the secondary router's address, a conflict will occur and the Internet will be lost.
The first thing you need to do is change IP address local network of the second router. Find the section LAN or Network → LAN SettingsIf the main router has an address 192.168.0.1, give the second one an address 192.168.0.2 or 192.168.0.254The main thing is that it is in the same subnet, but different from the main one and not within the range of distributed DHCP addresses.
What to do if the addresses match?
If you can't access the second router's settings due to an IP conflict, temporarily disconnect the cable from the primary router. Configure the second router separately, change its LAN IP, save the settings, and only then connect it to the primary network.
The second critical step is disconnection DHCP servers. Find the section DHCP Server and select the option Disable or OffThere should only be one address "distributor" on the network; otherwise, devices will receive incorrect gateway settings and lose internet access. After applying the settings, the router will prompt you to reboot and log in using the new IP address.
- 🔧 Go to your LAN settings and change the IP to one that is unique to your network.
- 🚫 Find DHCP Server and click "Disable".
- 💾 Save the settings and reboot your device.
Setting up a wireless Wi-Fi network
After a successful reboot and logging into the interface using the new IP address, we proceed to configuring the radio module. In the section Wireless or Wi-Fi set the network name (SSID). To create a seamless roaming-like experience (though it is not true roaming without 802.11r/k/v), the name and password must exactly match those of the main router.
However, there's a caveat. If you want to manually switch between access points, give the second router a unique name, for example, Home_Wifi_BedroomIf the goal is automatic switching, use the same ones. SSID and a password, but separate the channels. For 2.4 GHz, channels 1, 6, and 11 are optimal so they don't overlap.
Select an encryption method WPA2-PSK (or WPA3 if both devices support it). Using legacy WEP A private or open network is unacceptable from a security standpoint. The password must be complex, as you now have two physical entry points to the network, making perimeter security critical.
⚠️ Attention: Interfaces of routers from different manufacturers (for example, Asus against TP-Link) The Wi-Fi section may be called differently: "Wireless Mode," "Wireless Settings," or "Wi-Fi Network." Look for the keywords SSID and Password.
Final connection and testing of operation
Now that the software part is complete, let's move on to the physical connection. Take the prepared Ethernet cable. Plug one end into any available LAN port the main router. The other end is in LAN port configured secondary router. Leave the WAN (Internet) port on the second device empty!
Once connected, the LAN indicators should light or blink, indicating a link. Wait 1-2 minutes for the devices to exchange packets. Connect your smartphone or laptop to the created Wi-Fi network. If the internet is working and the IP address assigned to the device is in the range of the main router, congratulations, the setup is working!
Check the internet speed in the far room using Speedtest. It should be close to the speed near the main router. If you notice significant drops, check the cable quality—for gigabit speeds, all eight wires should be intact and properly terminated.
Common errors and how to fix them
Even if you follow the instructions correctly, problems may arise. The most common one is "No internet access" even though Wi-Fi is connected. This almost always means that DHCP hasn't been disabled on the secondary router, and devices are receiving addresses from it rather than the main gateway. Double-check your DHCP settings.
Another issue is the inability to access the second router's settings after changing the IP address. In this case, a factory reset via the button will help. ResetAlso, make sure your computer's network card is set to obtain an IP address automatically, and not to assign a static address from another subnet.
- 🔥 IP conflict: Two devices with address 192.168.0.1 on the same network.
- 🔄 Two DHCP: Devices receive an incorrect gateway and cannot see the Internet.
- 🔌 Invalid port: The cable is plugged into the WAN instead of the LAN on the second router.
If the second router supports the Access Point Mode in hardware (for example, in the menu Keenetic or Asus If there's a mode switch, use it. In this case, the system will automatically disable DHCP and reassign ports, making your life easier. However, manual configuration via LAN-to-LAN works for any hardware.
Is it possible to connect two routers via Wi-Fi without a cable?
Yes, this is called WDS bridge mode or client mode. However, speed will drop by at least 50%, and stability will be affected by interference. A wired connection (LAN-to-LAN) is always preferable for fixed access points.
Do I need to set the same Wi-Fi password on the second router?
For a comfortable experience, it's recommended to use the same password and encryption type. The network name (SSID) can be the same for pseudo-roaming or different to clearly identify the access point you're connected to.
Why doesn't the Internet work after setup?
You most likely forgot to disable the DHCP server on the second router or connected the cable to the WAN port. Check these two points first. Also, make sure the second router's IP address is not the same as the primary router's.
Will a second router reduce internet speed?
When connected via cable (access point mode), speed losses are minimal and unnoticeable in everyday use. The only limitation may be the port speed (if they are FastEthernet 100 Mbps, and the plan is higher).
