@davidyu
Thanks, it seems you are using the same type of adapter for your T60, as I am
having bad experience with on more ThinkPads from the R-series, and that too
have been reported not working above. What is different is that you are
probably using a Certificate (LEAP) and WPA or WPA2
My T40 use Atheros AR5211 chip which didn't work with Ath5k driver.
However, my another T60 with Atheros AR5212, works excellent with Ath5k.
I found T60 with Ath5k has faster connection and strong signal.
Hope this AR5211 bug could be fixed right away.

[Karmic] Atheros AR5211 - ath5k driver
@davidyu,
Could you please post a sudo lspci -vvnn and a dmesg | grep -i phy from
your working T60, there are still R/T60 with AR5212 based adapters not working
without using the madwifi driver. What encryption are you using ?
Thanks in advance.

The symptoms I am seeing after having completed step two are transfer
rate drops to zero (which can last up to 20 seconds), very low transfer
rates (no more than 2 or 3 kb per second for several minutes) and
overall very heavy spikes (transfer rate drops from 2 mb to 50 kb then
goes up again -
Finally, I followed all 3 steps , but still failed.
At last, I use Madwifi driver to connect my wifi.

For those of you who have ran apport-collect to post debug information,
if you could also add a comment describing the specific issue you are
seeing that would be great. I should have been more clean in the bug

Since upgrading to the Karmic Release, I haven't been able to connect to
any WiFi point using WPA. I can connect to open APs just fine with no
problems. I have am running the full release of Karmic, so that covers

connection on WPA.
Here is my lspci -vvnn after I resolved my issue with step 2. The
wireless network went from dropping connection randomly, but often,
under load (pre step 2) to working without problems (post step 2).

Yes, I'm using the self-compiled madwifi-driver with Karmic. It seems to

No luck with that one either. Madwifi seems to be only driver working at

I would be nice if you could supply us with a sudo lspci -vvnn, as there is
more than one Atheros based adapter for the ThinkPad T40 series.
From all the logs above there seems to be two types Atheros adapters suffering
from this issue, a Philips branded and a IBM and Lenovo branded

I did a fresh install of Ubuntu 9.10 (i386) on my IBM ThinkPad T42.
Wireless (WPA2 PSK) did work, but the connection dropped randomly under
load (Reconnected to my AP at least one time pr 2 minutes).
Did step 2, rebooted, and it now works. I have downloaded gigabytes of

step 2 changed my problem from not being able to connect at all with
WPA2 / Personal to able to connect with WPA2 and having lousy
