I upgraded to Jaunty yesterday and again had to struggle with my wireless. This time, it wasn't necessary to install a new kernel module. Instead, I just needed to remove Network Manager and set up wpa_supplicant . Here's my new /etc/network/interfaces that I configured for my WPA2 PSK AES TLA network. auto wlan0 iface wlan0 inet dhcp wpa-driver wext wpa-conf managed wpa-ssid myssid wpa-ap-scan 1 wpa-proto RSN wpa-pairwise CCMP wpa-group CCMP wpa-key-mgmt WPA-PSK wpa-psk mypsk With that, all I needed to do was sudo /etc/init.d/networking restart .
