My new S25 is dropping wireless connection constantly. My old S21 kept right next to it is perfectly fine. 

Wifi6e

The only connection change i see is S25 - WPA3 connection while S21 - WPA/WPA2. 

It keeps saying WPA3 connection is required. 

I have Xfinity. The latest gigabit connection and latest router. 

Any help would be appreciated.
