I’ve been having some problems connecting my EeePC to wireless networks of late. The problem was that it didn’t detect available wireless networks, nor did it connect to the ones I’d already defined.
It runs Ubuntu 8.04, and I originally had to fuss around a bit to get the Atheros WLAN card to work. After reading more than a few forum posts, I found that reinstalling MadWifi most likely would fix the problem. The fix is done solely in the command line shell. I ran the following commands, in succession:
tar xzvf madwifi-hal-0.10.5.6-current.tar.gz
apt-get install build-essential linux-headers-$(uname -r)
echo ath_pci >> /etc/modules
A quick reboot later, I was up and running, and happy as a clam.
