Title:
ath5k driver (AR2413): dropped packets, high latency
Status in “linux” package in Ubuntu:
Expired
Bug description:
Using the ath5k driver (AR2413 chip) on the lucid kernel I get high
latencies and dropped packets. eg. Web pages load slowly if at all. I
believe it is related to this bug in fedora:
https://bugzilla.redhat.com/show_bug.cgi?id=506372
I tried installing linux-backports-modules-wireless-lucid-generic
(linux-backports-modules-wireless-2.6.32-21-generic at the time of
this report) and also tried loading ath5k with:
modprobe ath5k nohwcrypt=1
AND
modprobe ath5k nohwcrypt=0
Neither of these had any effect on the problem. However, installing the
2.6.33 kernel from the mainline ppa fixes the problem completely!
http://kernel.ubuntu.com/~kernel-ppa/mainline/v2.6.33/
I will attach the results of pinging my router under both the 2.6.32
and 2.6.33 kernels for proof of the fix.
A backported patch for the lucid kernel would be great! :-)
