Might one ask which distribution you're using, and which processor?
If you're using a 64bit processor, the ath5k
drivers may fail for the older Atheros 5008EG chips.
Note also that having multiple wireless drivers installed will almost always cause all of them to fail. Since you're getting some
response, that's unlikely to be your problem. Still, it might be worth checking in the dmesg
output for mentions of Atheros
Does your distribution automatically install the NetworkManager
application? If so, and if you're using GNOME or KDE as your desktop, look for the network manager applet's icon in the system tray. Clicking on the icon should display a list of access points upon which you can click to connect. (The initial click can be either a left or right click depending on you distribution packager's choice, so, if one doesn't work, try the other. One shows the list, the other shows network options.)
