Tab S4 Wifi Issues

[Jephy]

Hi,

I seem to be having an issue with one of our tablets, namely the S4. It's suddenly started stating "incorrect password" and I have to keep trying to reconnect until it eventually connects (without even changing the password).

When I check on my router, there are no errors but it shows it authenticating but not doing the WiFi handshake then disconnecting.

The router is an Asus AX110000 which is a WiFi 5 router, it uses WPA2/WPA3 authentication, 2.4Ghz using channel 13 mainly (I'm in the UK) and the 2 5Ghz bands use 64/100 respectively.

I'm starting to think the tablet doesn't support 2.4Ghz on 12/13 and 5Ghz DFS channels, does anyone have any insight on this?
