How to Turn a Router into a Wi-Fi Switch: A Complete Guide

An old router gathering dust on a shelf can become a useful device for expanding your home network. Instead of buying a separate switch (switch) and an access point, you can combine their functions in one device - by converting the router into Wi-Fi enabled switchThis solution is suitable for offices, large apartments, or homes that require increased wired ports while simultaneously providing wireless connectivity in remote areas.

The transformation process doesn't require any special skills, but it does have its own nuances depending on the router model and current network configuration. In this article, we'll discuss step-by-step instructions for popular brands (TP-Link, ASUS, Keenetic, Zyxel), we'll explain which settings need to be changed and warn you about common mistakes. You'll also learn how to check hardware compatibility and avoid IP address conflicts.

Why Use a Router as a Wi-Fi Switch

The advantages of this solution are obvious:

• 💰 Saving money — no need to buy a separate switch and access point.
• 📡 Expanding Wi-Fi coverage — the second router can work as a repeater, amplifying the signal in remote rooms.
• 🔌 Additional Ethernet ports — Most routers have 4 LAN ports that can be used for wired devices (IP cameras, Smart TV, game consoles).
• 🔄 Network flexibility — the ability to create a separate subnet for guest devices or IoT gadgets.

However, not all routers are suitable for this task. For example, older models with proprietary software (D-Link DIR-300, Tenda N3) may not support the mode AP Mode or Bridge. Modern devices (TP-Link Archer C6, ASUS RT-AX55) usually have this functionality out of the box.

It is also important to consider performance: if the main router gives the speed 1 Gbps, and the secondary is limited 100 Mbps, then devices connected to it will work slower. Check the technical specifications of your model before setting up.

Which routers can be converted into Wi-Fi switches?

Not every router supports the wireless mode access points (AP) or bridgeHere are the key compatibility criteria:

If your model is not in the table, check the documentation on the official website or look for items in the router menu. Operation Mode, Wireless Mode or AP ModeOlder devices (manufactured before 2015) often do not support these features.

⚠️ Attention: Some routers (eg. MikroTik) require manual configuration through WinBox or SSHIf you're not familiar with these tools, it's best to choose a model with a graphical interface.

Preparing a router for conversion to a switch

Before setting up, please follow these steps:

Reset to factory settings|Update firmware to the latest version|Connect the router to a PC via cable|Write down the MAC address of the primary router|Disable DHCP on the secondary router-->

1. Reset settings. Press and hold the button Reset for 10-15 seconds until the indicators flash. This will remove old configurations that may conflict with the device's new role.

2. Firmware update. Outdated software may not support the mode. APDownload the latest version from the manufacturer's website and update the router via the web interface (usually the section Administration or System Tools).

3. Physical connectionConnect the router to the computer via LAN port (not WAN!). The web interface can be accessed at 192.168.0.1 or 192.168.1.1 (check the documentation).

4. Recording the MAC address of the main routerIf you plan to use wireless bridge, you will need the MAC address of the primary device for binding. Find it in the primary router settings (section Status or Network Map).

5. Disabling DHCPThis is critical! If both routers are distributing IP addresses, a conflict will occur. On the secondary device, go to LAN → DHCP Server and deactivate the service.

Step-by-step setup of a router in Wi-Fi switch mode

Let's look at the universal instructions for most modern routers. Examples are given for TP-Link Archer C6, but the algorithm is similar for other brands.

1. Login to the web interfaceConnect to the router via cable, open the browser and enter 192.168.0.1 (or another address indicated on the device sticker). Log in (usually login/password - admin/admin).

2. Selecting the operating mode. Go to the section Operation Mode (or Working Mode) and select Access Point (AP). On some models (ASUS) this item can be called AP Mode.

3. Setting up a Wi-Fi network:

- Specify network name (SSID) - it may be the same as the main router or different (for example, MyNetwork_Ext).

- Choose channel - if the main router uses Channel 6, install Channel 11 to minimize interference.

- Ask password (It is recommended to use the same one as on the main router for convenience).

- In the field Security select WPA2-PSK (or WPA3, if supported).

4. LAN setup:

- Turn it off DHCP Server (as mentioned earlier).

- Install IP address secondary router on the same subnet as the primary router, but with a different last octet. For example, if the primary router has an IP 192.168.1.1, assign to secondary 192.168.1.2.

- Save the settings.

5. Connecting to the main network. Connect LAN port secondary router with LAN port primary (not WAN!). If you need a wireless connection, select the mode Wireless Bridge and enter the MAC address of the main router.

What to do if there is no AP mode?

If there is no mode in the router menu Access Point, you can emulate it manually:

1. Turn off DHCP And NAT.

2. Assign a static IP to the router in the subnet of the main device.

3. Connect the cable in LAN port (not WAN!).

4. Set up Wi-Fi as usual.

This method works on 90% of devices, but may require additional firewall configuration.

Setting up a Wireless Bridge

If laying a cable between routers is not possible, you can organize wireless connectionThis mode is called Wireless Bridge or Client Mode.

1. In the web interface of the secondary router, go to the section Wireless → Wireless Bridge (or Repeater Mode).

2. Click Survey or Scanto find the main router's network. Select it from the list.

3. Enter the password for your primary Wi-Fi network. Make sure the encryption type is (WPA2-PSK) matches.

4. In the settings LAN turn it off DHCP and assign a static IP (as in the previous section).

5. Save the settings and reboot the router. After connecting, the indicator Wi-Fi must burn constantly.

⚠️ Attention: In mode Wireless Bridge Connection speed may decrease by 30–50% due to double data transfer (router → bridge → device). For stable operation, use the range 5 GHz (if supported).

Checking functionality and troubleshooting

After setting up, run the tests:

• 🔌 Wired connection: Connect your laptop to LAN port secondary router and check internet access.
• 📶 Wireless connection: Connect to a new Wi-Fi network and run a speed test (for example, on speedtest.net).
• 🔄 Ping: Open command prompt and run

  ping 8.8.8.8

  - if the packets pass without loss, the setup is successful.

Typical problems and solutions:

• 🚫 No internet access: Check if it is disabled DHCP on the secondary router and whether the IP address is assigned correctly.
• 🔌 LAN indicators are not lit: Make sure the cable is connected to LAN port, not WAN. On some routers, the WAN port is automatically disabled in AP mode.
• 📶 Wi-Fi works, but there is no internet: In mode Wireless Bridge check if the security settings match (eg. WPA2-PSK on both devices).
• ⚡ Slow speed: If used 2.4 GHz, switch to 5 GHz or change the channel to reduce interference.

If your router doesn't save your settings, try:

1. Update firmware.
2. Reset settings and repeat configuration.
3. Use a different browser (eg. Edge instead of Chrome).

Additional features: guest network and VLAN

The converted router can be used not only to expand the network, but also to organize guest access or isolated subnets.

1. Guest network. In the Wi-Fi settings (Guest Network) Create a separate access point with limited access to local resources. This is useful for offices or apartments where you need to provide internet access to guests without compromising the main network.

2. VLAN (virtual networks). Some routers (ASUS RT-AX88U, TP-Link Omada) support port separation by VLAN. For example, you can distinguish:

- Port 1 — for IP cameras (isolated network).

- Ports 2–4 — for basic devices.

- Wi-Fi — for guests.

3. Traffic prioritization (QoS)If the secondary router supports QoS, set priorities for video streaming or online gaming. This is relevant if the device is connected via Wireless Bridge and the speed is limited.

⚠️ Attention: Configuring VLANs and QoS requires knowledge of networking technologies. Incorrect settings can lead to loss of access to the router. Before experimenting, save a backup copy of the configuration (Backup Settings).

FAQ: Frequently asked questions about converting a router into a switch

Is it possible to use a router as a switch without configuration?

No. If you just connect the router through LAN port without tripping DHCP and changing the mode, an IP address conflict will occur. The minimum required:

1. Disable DHCP on the secondary router.
2. Assign it a static IP in the main router's subnet.
3. Connect the cable in LAN port (not WAN!).

Which router is best for switch mode?

Optimal options:

• TP-Link Archer C6 - budget, supports AP Mode And 5 GHz.
• ASUS RT-AX55 - high productivity, AiMesh to expand the network.
• Keenetic Giga - simple interface, stable operation in AP mode.

Avoid outdated models (D-Link DIR-300, Tenda N300) - they may not support modern Wi-Fi standards.

Why doesn't Wi-Fi work after setup?

Possible reasons:

• Incorrect password for the main network (in mode) Wireless Bridge).
• Channel conflict (if both networks are running on Channel 6).
• There is no connection between the routers (check the indicators) Wi-Fi).

Solution: Reboot both routers and check security settings (WPA2-PSK).

Is it possible to connect an IP camera to such a switch?

Yes, but keep in mind:

• If the camera requires PoE, make sure your router port supports this function.
• For remote access, set up port forwarding (Port Forwarding) on basically router.
• If used Wireless Bridge, video delays may occur due to double data transfer.

How to return the router to normal mode?

Perform a factory reset (Reset) or select the mode in the web interface Wireless Router (Gateway). Don't forget:

1. Turn on DHCP.
2. Connect the internet cable to WAN port.
3. Configure PPPoE/L2TP (if required to connect to the provider).
