I wrote a while back on getting my ACX based wireless LAN card working in Ubuntu version 6.06. Now I have upgraded my machine and find that it is a bit different getting it to work under Ubuntu 7.04 (A.K.A. “Feisty Fawn”).

Essentially, the built-in ACX100 driver now correctly loads the firmware so you don’t need to fiddle with its parameters any more.

However, Fiesty introduces a new tool called “Network Manager” which does not get along with this driver. Network manager is installed by default so the first thing we need to do is get rid of it:

sudo dpkg -P network-manager network-manager-gnome

Then the card can be configured by editing the interfaces file:

sudo gedit /etc/network/interfaces

Here is my file. WEP keys have been changed to protect the innocent.

# This file describes the network interfaces available on your system
# and how to activate them. For more information, see interfaces(5).

# The loopback network interface
auto lo
iface lo inet loopback

# Wireless network
auto wlan0
iface wlan0 inet dhcp
        wireless-mode Managed
        wireless-essid MyNetwork # Replace with the name of your wireless network.
        wireless-key 23BA7823B4  # Replace with your own key or omit if not using WEP.

Then reboot and you should be good to go!

One more thing before I finish. Be aware that although this card supports WEP authentication, it does not support WPA so make sure your wireless router is not set to WPA.

 Update

I have just replaced this card with a TP-Link one. It is sooo much faster and more reliable than the NetGear card. Read my article on setting up the TP-Link.
