Ubuntu 9.04 and TKIP+AES Encryption

September 25, 2009

If you've configured your wireless access point to use TKIP+AES encryption for your EeePC 901, the default rt2860 (v1.8.0.0) kernel module included in Ubuntu 9.04 will not allow you to authenticate and connect to the wireless network. The only way to get this working is by downgrading to v1.7.1.1.

Download Module

wget http://www.array.org/ubuntu/dists/intrepid/eeepc/binary-i386/rt2860-dkms_1.7.1.1_all.deb

Remove Old Module

cd /lib/modules/`uname -r`/kernel/drivers/staging/rt2860/
sudo mv rt2860sta.ko rt2860sta.bak

Install New Module

sudo dkpg -i rt2860-dkms_1.7.1.1_all.deb

Reboot upon completion and connect to your wireless network.

EDIT: Looks like the latest Ubuntu 9.04 updates have fixed this issue?
