Therefore, flip your router and check the physical connection between the router and the modem. Tighten the connection if it appears to be loose. After that, observe if the same ‘TP-Link not detecting WAN’ issue comes up.

Modify the Router’s LAN IP Address

The default LAN IP address of most TP-Link routers is However, these private IP addresses can be the same as other devices’ IP addresses. As a consequence, there can be a conflict among existing routers and modems.

Clone your PC’s MAC Address

Primarily, ISPs assign a definite MAC address to your PC when you access an internet connection for the first time. If you add a router to the existing network, then your PC’s MAC address might get revised, and the ISP might not accept that. This is why you might come across the TP-Link router not detecting WAN issues. You need to clone your PC’s MAC address to solve this problem.

Log in to the web admin panel of the TP-Link router and click the Network option from the left pane. Now, click the MAC Clone option and hit the Clone MAC Address button to eliminate the trouble. Don’t forget to click the Save button.

Give your Network Component a Power Cycle

If nothing is working, then you should power cycle your modem and router. This is a simple hack when you are facing technical glitches. First, you need to turn off your TP-Link router along with the modem and keep them shut down for a minute or two.

Next, turn on your router first. Then, switch on your modem and wait for a stable connection. The internet light should be solid on the modem and then check if the ‘TP-Link router not detecting WAN’ issue persists.


As a final resort, you can check if the WAN connection is appropriate or not. Open the admin panel and go to the WAN settings under the Network option. Check the connection type, and you can reconfigure it from the WAN Connection Type drop-down list.

After that, hit the Save button and power cycle the network setup. In addition to this, you can check the cables and replace them if the TP-Link router not detecting WAN issues still annoys you.
