I am an internet provider. I currently have 18 pcs on my desk after returns from customers who complain about the operation of the router. The customers have a point. What's happening. Routers have the latest version 22.03.2 anyway, it doesn't matter on older ones, the same thing happened. Routers hang after a few days of operation 2-3 days. You can't connect to wifi or the transmission to the router's ip is lost - no gateway and ip address. - that's the symptom. I configured them in bridge wan + lan, set him a rigid IP 10.0.100.2 and connected to another router, which gives dhcp. Nothing helped. Cannot ping 10.0.100.2 when hanged. The problem is catastrophic OPENWRT is completely wrong for this router. There are no problems with the original firmware. Only sometimes the wan changes the speed of 100Mbit to 10Mbit automatically - on the original tplink firmware, which I also do not understand. It doesn't always happen. Generally firmware 22.03.2 and previous are not usable for Archer C6 v3.2 and C6U same symptom. The ip transmission is lost, the router freezes. There is also a problem with connecting to WIFI. Lots of bugs must be in fw. I have stopped using these routers and Openwrt anymore because customers are getting annoyed and outraged by the internet and it's not my fault but Openwrt's fault!
i think the problem is the mt7613 5ghz radio. it freeze the device, no dhcp, no static address no lan, sometime nothing work,only a reboot, i observed that on another device.
