Hi, not sure how to save settings in a live cd environment, but here's something
that MIGHT work to test the wireless connection -
Open terminal, and type sudo modprobe ath-pci
enter your password, then press enter
next type sudo dhclient ath0
after it's done running through it's spiel (might take a minute)
click on the networking icon on the taskbar and see if it picks up your wireless.
hopefully this helps
