Hi 

I am also getting the same issue I contacted my ISP they are saying everything is okay from their end and I need to change the router and when I checked with the TP-link support they said everything is okay and your firmware version is also up to date. Whenever the internet drops my internet light turns to orange.

I reset my router twice but the same issue is going on. Also, someone said only 2.4 GHz got hung for some time but same issue is going on with the 5GHz band and even with LAN also.

Whenever the internet is down I get the below logs under the logs tab.

0 lan port link down
