I too have an Atheros problem. I believe my card is the 5212. I use the DLink DWL-G650. The card is seen, signal strength at 85%-90%. Will not associate to AP. Worked like a charm in Dapper. I have to plug-in to ethernet to get internet. Let me know if you want any specific information (terminal outputs, etc.). I am a newb and would need some slight instruction to get the info you may need. BTW, ath0 shows up in iwconfig, but not in ifconfig.
