My Laptop is Acer 5742G with "Npilfy 802.11 wireless".
I have both windows 7 and Ubuntu 12.10
Earlier when I had Ubuntu 12.04, the wireless was working fine, but after installing 12.10 wireless is not working at all, although it is still working in windows.
I am not able to see "Wireless Networks" in the Network Manager nor in the Network Settings.
This was the output I got for rfkill
0: acer-wireless: Wireless LAN Soft blocked: no Hard blocked: no 1: acer-bluetooth: Bluetooth Soft blocked: no Hard blocked: no 2: hci0: Bluetooth Soft blocked: no Hard blocked: no
This is a snapshot of my Additional Drivers settings.
As you can see, the required driver for wireless is installed.
