Public bug reported:
In trying to diagnose a problem with wireless authentication (nm-applet
asks for password, wicd says "bad password") for a new TP-Link WN951N
PCI wireless card (native kernel driver is ath9k), I found that purging
the ureadahead package solved my problems. I am running Ubuntu 11.04
amd64 on a SSD as my main system (shouldn't ureadahead be removed by
default on SSDs?).
The Ubuntu 10.10 and 11.04 32 bit live CDs could connect no worries, but
the Ubuntu 11.04 64 bit live CD produces the same problem for me.
Before testing with the live CDs I had tried updating/downgrading the
kernel several times (even to version 3.0.0-0300rc6), changing
encryption, password, and channel -- all with no success. Loading
wireshark I noticed that whilst I could scan correctly for my
modem/router, no packets were actually being set or received. After
purging ureadahead and rebooting (several times to make sure it works) I
can now see the packets being exchanged in authentication and it all
works as expected.
The output of dmesg | grep ath was a constant loop of:
[<time>] wlan0: associate with xx:xx:xx:xx:xx:xx (try 1)
[<time>] wlan0: associate with xx:xx:xx:xx:xx:xx (try 2)
[<time>] wlan0: associate with xx:xx:xx:xx:xx:xx (try 3)
[<time>] wlan0: association with xx:xx:xx:xx:xx:xx timed out
