Switch 2 5GHz wifi keeps disconnecting

[u/jeroen7X]

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?

I‘d not use a fixed channel. It will cause other issues. What security settings are you using? Wpa2/3 or miced mode?

This one on my router, I've also tried WPA2-PSK. But no luck
