Instructions for loading the Acer IPN2220 wireless drivers with ndiswrapper… it’s really an InProComm IPN2220 802.11g wireless adapter.
1.) Install the ndiswrapper-utils package… open a terminal and enter:
sudo apt-get install ndiswrapper-utils
2.) Download the windows driver on the Acer website (referenced “Acer IPN2220 Wireless LAN Card NDIS Miniport Driver 2.10.03.2004”)… or from here:
http://support.acer-euro.com/drivers/notebook/tm_4000.html
and place the downloaded a802.zip file in your “Home” folder.
3.) Back in the terminal enter:
cd ~
unzip a802.zip
(hit enter after each line… you should now have a folder called A802 in your Home folder)
4.) Still in the terminal enter:
sudo -cp -Rf ~/A802/ /opt/
(to copy the A802 folder to /opt/)
5.) Still in the terminal enter:
sudo ndiswrapper -i /opt/A802/Win2k/neti2220.inf
(to load the driver with ndiswrapper)
6.) Still in the terminal enter:
sudo ndiswrapper -m
(to create the module for the linux kernel)
7.) Still in the terminal enter:
sudo modprobe ndiswrapper
Now check in NetworkManager to see if your wireless network is detected… if it is, configure your wireless connection.
8.) Now to load the driver every time your system boots… back in a terminal, enter:
sudo gedit /etc/modules
and add the line:
ndiswrapper
at the end of the file… save and exit.
You’re done.
(you can now delete the a802.zip file and the A802 folder from within your Home folder if you wish)
