troubleshooting wireless network issue
Does anyone have suggestions on troubleshooting an issue with
apparently intermittent wifi on Fedora after upgrade to 25? The
machine is working okay in its location on windows and was okay on
F22, and other devices are alright on the access point. The
networkmanager status (KDE) doesn't show the connection dropping,
however fairly frequently a site will not respond. It's particularly
noticeable in Ajax or form submission, e.g. a site login (such as
gmail) just wont go any further, or sites that load as you scroll down
(such as facebook) just hit a point and stop.
I'd link to what I've already posted on the users list (thread
Terrible F25 WiFi Performance), but hyperkitty says there haven't been
any messages in March. So:
Device:
02:00.0 Network controller: Qualcomm Atheros AR93xx Wireless Network
Adapter (rev 01)
Module:
driver: ath9k
version: 4.9.14-200.fc25.x86_64
firmware-version: N/A
expansion-rom-version:
bus-info: 0000:02:00.0
supports-statistics: yes
supports-test: no
supports-eeprom-access: no
supports-register-dump: no
supports-priv-flags: no
Which is the correct driver, unless there's been a regression. It
seems like key rotation or something is not taking place smoothly. I
see quite a lot of this while it's connected (journactl output, lines
may be truncated):

I've tried setting the domain to GB as in this bug:
https://bugs.mageia.org/show_bug.cgi?id=18935 but still see those
WORLD domain entries in the log (and the problem persists). Have also
tried disabling ipv6 with no success.
