WiFi flakiness after recent upgrades

[Max Pyziur]

Greetings,

I have an elderly Dell XPS 13 laptop (L321x); it seems that after a recent 
software upgrade, the Wifi has become intermittant. As a fallback, I have 
a USB ethernet connection to cabled switch that is delivering steadily.

All other wifi devices (samsung phones, etc) are connected and operating 
correctly.

Is anyone else having difficulties?

Thanks,

Max Pyziur

I was just thinking about posting this, too.  Lenovo T530 with Intel 
Corporation Centrino Ultimate-N 6300 (rev 3e)

Wifi connects, then drops, then reconnects. Rinse and repeat.

The Wi-Fi card on my wife's XPS 13 failed a while back - the behavior
was intermittent dropped connections, poor throughput, etc.  I did
some googling and found multiple reports about a specific wifi card
used in some XPS 13s that was known to get flakey after a while -
sorry, but I don't remember specifics as to the card.

I replaced the wifi card with a new one - an Intel Corporation
Wireless-AC 9260.  No problems since.

"I have a witness."

I've rebooted to an earlier kernel (kernel-5.16.14-200.fc35.x86_64), and 
things seem to be stable, wifi-wise. On the newest kernel 
(kernel-5.16.15-201.fc35.x86_64) things would have become problematic w/in 
a few minutes.

Am I doing this correctly, or are should other approaches be tried?

I went through the same process.

kernel-5.16.15-201.fc35.x86_64 causes the wifi to drop regularly
kernel-5.16.14-200.fc35.x86_64 works well.

This is with an Atheros wireless chip

Chris

I just upgraded to the *16* kernel. This problem continues.

I'm now back to running the *14* kernel.

Is there a way to report this problem?

Much thanks,

Yes in the fedora bugzilla.

Bugzilla reports are useful as they will be the first place users check
after encountering problems, but in my experience, upstream devs
may already be aware of the issue and can often provide a patch if
you are willing to install it from source.  For Secure Boot you
may need to create a machine-owner key (MOK).  Instructions are
available.for Fedora 35:
