Hey,
I just switched from Vista to Ubuntu, and have been quite pleased, however I am quite confused as to how you set up the Wifi, I have tried forum after forum and have got to no conclusion. Could anyone help me? I know how to use a computer, but not so much Ubuntu. Are there any easy steps?

Thanks!

First do the following in a terminal window and post the output back here. We'll go from there.

You will need to use the madwifi drivers for your atheros adapter. Here is just one post on doing so (it's a little longer than needed because the guy screwed up a couple of times).

Just ask back here if you have any questions or problems.

Which link do I use? I have no idea about the programs they're talking about...

From what I can see, you need to do the following:

In a terminal windows (applications/accessories/terminal):

sudo apt-get update && sudo apt-get install build-essential

wget http://snapshots.madwifi.org/madwifi-hal-0.10.5.6/madwifi-hal-0.10.5.6-r3835-20080801.tar.gz

tar xvf madwifi-hal-0.10.5.6-r3835-20080801.tar.gz

cd madwifi-hal-0.10.5.6-r3835-20080801

sudo make

sudo make install

sudo modprobe ath_pci

Then reboot. From further reading in that thread, it also appears you may want to turn off bluetooth support. It would also appear that perhaps the light on your adapter may not show the "correct" color but it will probably work anyway.

I don't have experience using that chipset, so I'm basing the above on what I have gleaned from the link.
