A wifi card with the ath5k driver used to work properly until a couple of weeks ago. Now, if I ping the router the response times sometimes are okay but often fluctuate into the range of many hundreds or thousands of milliseconds. Occasionally the connection breaks down entirely.
My laptop, which uses a different card, works fine (typical ping response times of 2 ms), so its probably not the router which is faulty.
I use opensuse 11.3 x86_64, currently with the 2.6.34.7-0.7 desktop kernel and knetworkmanager.
Thanks in advance for any help.
Okay, have you updated lately? Done anything strange? Messed with wireless settings?
Have you tried to recompile and install compat-wireless? If you do, I suggest running
./scripts/driver-select ath5k
in the compat directory prior to make and make install.
