Comment 30 for bug 339891

Just so everyone knows, there is an array.org kernel for Jaunty:

sudo -s
echo "deb http://www.array.org/ubuntu jaunty main" > /etc/apt/sources.list.d/array-jaunty.list
wget http://www.array.org/ubuntu/array-apt-key.asc
apt-key add array-apt-key.asc
apt-get update
apt-get install linux-netbook-eeepc
sudo apt-get remove linux-generic linux-image-generic linux-restricted-modules-generic
exit

These commands will add the new jaunty repository and install the kernel, the apt-get remove will remove the metapackages to stop the generic kernel from updating, but will not remove the current kernel.

This kernel has solved my issues with WLAN with WPA (TKIP). I'm not sure about what's different, havent looked into that yet, but adamm would be the guy to ask :)
