I've recently bought a new router, TP-Link Archer GE550, and for some reason now my Switch 2 keeps disconnecting from 5GHz wifi. It still shows that there is a connection but I can't go online and the connection test keeps failing. Sometimes it just works again but only for a short while. I've tried many things already:
-Turned of IPV6
-Changed DNS settings
-Changed MTU to 1500
-Restart of console
-Turn on hidden connection
-Fixed channel to 36
-Put bandwidth on 20/40 and 80
It's only a problem on my Switch 2, all my other hardware works fine. Does anyone know how to fix this?
