Wifi is not working after upgrade to Ubuntu 11.04.
The network manager on the task tray states that wireless is disabled by hardware switch. Wireless is enabled in the BIOS and the switch on the laptop is enabled.
I tried the following commands suggested by Seth Forshee (sforshee) and wifi was activated, but when I rebooted wifi was not activated and the following commands did not work again.
sudo modprobe -r acer_wmi
rfkill unblock all
The following command produces --> SIOCSIFFLAGS: Operation not possible due to RF-kill
sudo ifconfig wlan0 up
The following command still shows --> Hard blocked: yes
rfkill list
Wireless works when I swap the Ubuntu HDD with a Windows HDD to test.
