Many users are familiar with the situation where a desktop computer or smart TV finds itself in a wireless network "dead zone." Often, the PC's built-in WiFi module is unstable, and running a long cable across the entire apartment is not feasible due to aesthetic or design constraints. In such cases, an old router can be converted into a powerful signal receiver.
Using TP-Link router as WiFi adapter This not only ensures a stable connection but also shares internet access with multiple devices via LAN ports. This solution is often more reliable than buying a cheap USB dongle, especially if you have an extra device from your ISP or an older model.
In this guide, we'll walk you through the process of reconfiguring your equipment, explore the differences between operating modes, and answer frequently asked questions. You'll learn how to transform your TP-Link Archer or a simpler model of the series TL-WR into an efficient bridge to expand coverage.
Operating principle and required modes
A standard router receives internet via a WAN cable and distributes it over the air. To use it as a receiver, the device's logic must be modified. TP-Link firmware includes special modes for this, such as WDS Bridge, Client or Universal RepeaterThe specific mode you select depends on your device's firmware version and model.
⚠️ Note: The menu interface may differ depending on the year of manufacture of your device and the firmware version (green or blue shell). If you don't find an exact match, look for sections with similar functionality in the "Wireless" or "Operating Mode" menu.
Mode WDS (Wireless Distribution System) Allows you to connect multiple wireless networks into one, preserving clients' MAC addresses. This is the most universal option for both old and new models. Client (Client) turns the router into a simple network card that transmits signals only to the LAN ports, which is ideal for connecting a single PC or gaming console.
It's important to understand that when switching to receiver mode, the device stops acting as a router for its subnet, unless configured otherwise. IP addressing will be assigned to the main router distributing the internet. This simplifies network management, as all devices will be on the same segment.
Preparing for equipment setup
Before you begin, you need to perform a few preparatory steps to avoid IP address conflicts and loss of interface access. First, reset the secondary router (which will act as the adapter) to factory settings. To do this, press and hold the button Reset for 10-15 seconds with the power on.
After the reset, connect your computer to any LAN port of the device you're configuring using a cable. Don't connect the WAN port or connect the routers yet. Open a browser and enter the address 192.168.0.1 or tplinkwifi.net to log in to the control panel. Standard login information is usually found on a sticker on the bottom of the case.
A critical step is to change the secondary router's local network IP address if it matches the primary router's address. For example, if the primary router has the address 192.168.0.1, then the custom one needs to be set 192.168.0.254This is done in the section Network → LAN.
☑️ Preparing for setup
Setting up WDS Bridge mode (Classic method)
This method works for most models with a green or orange interface skin. Go to the menu Wireless → Wireless SettingsHere you need to change the channel to the one used by the main access point. Make sure to lock the channel, as WDS requires a static value.
Check the box next to the item Enable WDS BridgingAfter activation, a button will appear. Survey or SearchClick it to let the router search for available networks. Select your primary network from the list and click ConnectThe system will automatically fill in the MAC address and SSID of the main access point.
In the field Key type And Key Enter the password for your primary WiFi. The encryption type must match the primary router's (usually WPA2-PSK). After saving the settings, the device will require a reboot. Don't forget to also disable the DHCP server on the secondary router in the section DHCP → DHCP Settings, having chosen Disable.
Client Mode for new models
Devices with a blue interface (Tether OS) and Archer series models often have a separate operating mode. Go to the section Advanced → Operation Mode (or "Operating Mode"). Select an option Client or Universal Repeater and save your selection. The router will automatically reboot.
After rebooting, the interface will change. You will need to find the section Network → Internet or Wireless, where a list of available networks will appear. Select your home WiFi, enter the password, and press ConnectIn this mode, the DHCP server is usually disabled automatically.
Unique feature of Client mode on TP-Link: Unlike WDS, this mode may not forward broadcast packets, which is sometimes necessary for discovering printers or media servers on the network. If you need full LAN functionality, WDS or cabled access point mode is preferable.
To check the connection status, go to StatusThe Wireless section should show "Connected" or "Up," along with signal strength and connection speed. If the status is "Disconnected," check the password entered correctly and the distance to the primary access point.
Comparison of WiFi operating modes
Understanding the differences between these modes will help you choose the best option for your situation. Each has its own advantages and limitations in terms of speed and device compatibility.
| Parameter | WDS Bridge | Client Mode | Repeater |
|---|---|---|---|
| Connection type | Bridge between segments | Full-fledged network client | Signal amplifier |
| Speed | High (minimal losses) | Maximum | Reduced by 50% |
| Compatibility | Requires configuration on both routers | Works with any router | Works with any router |
| VLAN support | Partial | Full | No |
As can be seen from the table, the mode Client is the easiest to set up if your router supports it. Mode WDS More flexible, but requires manual configuration of channels and sometimes MAC addresses on the main router. Repeater mode creates a new network with the same name, but may reduce speed.
Why does the speed drop in bridge mode?
Speed can decrease due to using the same frequency to simultaneously receive and transmit data. Dual-band routers solve this problem by receiving the signal on 5 GHz and transmitting on 2.4 GHz.
Advanced settings and security
After a successful connection, it's recommended to tighten security. Even if the main router protects the network, a secondary node can become a vulnerability. Make sure the secondary device has the latest firmware. You can check this in the section System Tools → Firmware Upgrade.
If you're using WDS mode, it's a good idea to configure MAC address filtering on the primary router. Copy the secondary router's wireless interface MAC address (found on the label or in the status bar) and add it to the whitelist of allowed devices on the primary access point.
It's also worth disabling services on the secondary router, such as UPnP, Remote Management, and WPS, if they're not in use. This will reduce the load on the device's processor and reduce the potential attack surface. Gaming consoles may require port forwarding, which should now be configured on the primary router for the IP address of the connected device.
Diagnostics and troubleshooting
The most common issue is that the router doesn't see the network or doesn't connect. Make sure the channels on the primary and secondary routers match and are fixed (not Auto). The channel width range should also be identical (20 MHz or 40 MHz).
If you have a connection but no internet, check your DNS settings. Try manually entering DNS servers (for example, 8.8.8.8) in the WAN or LAN settings of the secondary router. Also, make sure there are no IP addresses conflicting: the primary router and the receiving router should have different addresses in the same subnet.
⚠️ Note: If you change the wireless network settings (SSID, password, channel) on the primary router, the connection to the adapter will be lost. You will need to reconfigure WDS or Client mode on the secondary device.
If you experience persistent connection drops, try repositioning the antennas. Vertical antenna placement usually provides better coverage. If you're using the 5 GHz band, ensure there are as few obstacles between the routers as possible, as this band has difficulty penetrating walls.
What to do if you forgot the password for the secondary router?
The only way is to perform a hard reset by holding the Reset button for 10 seconds. All settings, including bridge mode, will be deleted.
Frequently Asked Questions (FAQ)
Is it possible to use the WAN port of a TP-Link router to connect to the main router in adapter mode?
In standard WDS and Client modes, the WAN port is typically unused or functions as a regular LAN port. However, in Access Point mode or some versions of Universal Repeater mode, connecting a cable from the main router to the WAN port is possible if the device supports automatic connection type detection.
Will my internet speed decrease when using my router as a WiFi adapter?
A speed reduction is inevitable, but its degree depends on the method. With a wired connection (access point mode), losses are minimal (1-5%). With a wireless bridge (WDS/Repeater), speed can drop by 20-50%, since the radio module operates in half-duplex mode, receiving and transmitting data alternately.
Do all TP-Link routers support WDS mode?
The vast majority of TP-Link models support WDS, but implementation may vary. In low-cost N-series models (TL-WR740N and similar models), functionality may be limited. Modern dual-band Archer models offer full WDS support, but it's sometimes hidden in the "Wireless Mode" menu.
Do I need to disable the DHCP server on the second router?
Yes, this is critically important. There should only be one active DHCP server on the network (on the main router). If DHCP is left enabled on the second router (the one acting as an adapter), devices will receive incorrect network settings and the internet will not work.
