Removing and blacklisting the acer_wmi module present in Linux 2.6.38-8-generic kernel under Ubuntu 11.04 on Lenovo Thinkpad Edge E520 with Centrino Wireless-N 1000 chipset fixes wireless network connectivity instantly.

$ rfkill list all
$ sudo rmmod -f acer_wmi
$ sudo rfkill unblock all
$ sudo su
# echo "blacklist acer_wmi" >> /etc/modprobe.d/blacklist.conf
# exit
