I went ahead and bought the TP-Link TL-WN651G wireless card that is supposed to have the Atheros AR5212 chipset acording to
http://madwifi.org/wiki/Compatibility/TP-Link#TL-WN651G. I said supposed to because i didn't realy check which chipset is on the card. Well anyhow i pluged in the card and went to interfaces (asign) and there it was the ath0 wifi card. I just pressed the add button and selected which card to asign and i was than able to configure the settings for the ap. I selected hostap and all the other little details needed just as in any other router bought at the store. The only other little thing that had to be set up was I had to select to bridge this wifi card with my LAN and than I had to go to the firewall rules and select the wifi at the top and add a rule which permits everything that comes on the wifi connection and than the magic began... no i mean the internet started working
