Hi all!

I can confirm that the
[code] sudo iwconfig wlan0 rate 11M [/code]
command stopped the
ath5k phy0: noise floor calibration timeout (2447Mhz)
errors from disappearing, in case that's of any use. (I didn't see the other errors mentioned in this thread, but I have the roaming to none problem: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/291760)

Is there anything one can do to get rid of this problem? Does enabling intrepid-proposed help?

I have an IBM T42 laptop with intrepid, the following kernel (uname -a output):
Linux Kexlerus 2.6.27-11-generic #1 SMP Thu Jan 29 19:24:39 UTC 2009 i686 GNU/Linux

lspci says that the wlan card is:
02:02.0 Ethernet controller: Atheros Communications Inc. AR5212 802.11abg NIC (rev 01)

And the module (sudo modinfo ath5k output):
