Comment 47 for bug 341952

I have the same problem with ath5k. This is an excrept of my dmesg:

[ 66.178325] ath5k phy0: noise floor calibration timeout (2442MHz)
[ 66.285455] ath5k phy0: noise floor calibration failed (2447MHz)
[ 66.393691] ath5k phy0: noise floor calibration failed (2452MHz)
[ 66.532438] ath5k phy0: noise floor calibration failed (2457MHz)

This is the ping to my router:

PING 192.168.1.1 (192.168.1.1) 56(84) bytes of data.

(should be < 1ms).

I have installed linux-backports-modules-jaunty (2.6.28.11.15) but nothing changed.

Linux ozzu 2.6.28-11-generic #42-Ubuntu SMP Fri Apr 17 01:58:03 UTC 2009 x86_64 GNU/Linux

Just upgraded to Jaunty... :(
