Bug#877711: firmware-atheros: Wifi connection becomes unreliable after upgrade to 20170823-1
Package: firmware-atheros
Version: 20161130-3
Severity: important
Tags: upstream
After upgrading to firmware-atheros_20170823-1 my wifi becomes unreliable,
working
for approximately 5-15 minutes before stopping transporting packets to my
access
point.
This issue is not sensitive to:
- The model of access point I am connecting to (tested vs OpenWRT, Apple &
Cisco)
- The kernel version (tested vs 4.11, 4.12 & 4.13 kernels)
I can unload the relevant modules and reload them and things work again... for
another
5-15 minutes.
The only sure-fire solution for me has been to downgrade to version 20161130-3,
which
seems to have no issues.
Sometimes I see the following trace in dmesg:

That doesn't show up every time when the drivers stop though, so perhaps it is
unrelated.
Thanks,
Andrew McMillan.
