Wifi loses connection - another case

Post by fbshilli » Sat Nov 09, 2019 8:24 pm

The wifi on my desktop slows and eventually loses its connection after a few minutes. Doesn't happen using windows.
I've tried a few things from other threads, but it still happens.
- power manager is off
- updated to kernel 5.3
- disabled hardware encryption for ath9k
- disable IPv6

Any suggestions would be appreciated. Thanks.
