Bug Description
Ubuntu 11.04 : Kernel 2.6.38.8 : Driver ath5k
Architecture: i386
Hardware: Atheros AR5414
There is almost no wireless signal strength received by the ath5k driver available in Ubuntu 11.04's kernel.
This is a critical regression from Ubuntu 10.10.
I have attempted the no hardware encryption kernel module parameter mentioned elsewhere to no avail.
ie. rmmod ath5k && modprobe ath5k nohwcrypt=0
Workaround
sudo su
apt-get install subversion
cd /usr/src
svn checkout http://
tar cfvz madwifi.tgz
cd madwifi
make && make install
echo "blacklist ath5k" >> /etc/modprobe.
echo "ath_pci" >> /etc/modules
modprobe ath_pci
