I've got a Zotac MAG HD-ND01 with XBMC live installed. This is built on Karmic Koala and runs very nicely through the wired NIC.
I configure the box using a cable. I'm using WPA2-PSK and it is clearly authenticating OK.. It gets an IP address.. the AP shows a connection to the box. My XP laptop connects to the access point OK.. just can't connect to the box via the wireless, and it can't see the network using wireless.
I have followed a number of threads on connecting Atheros 9XXX wireless (http://ubuntuforums.org/showthread.php?t=894177, http://ubuntuforums.org/showthread.php?t=1309605, http://ubuntuforums.org/showthread.php?t=930667) but no joy.
Any ideas? Also, can Ubuntu connect to the AP at any speed greater than 54MB? My windows PC connects at 144MB+ . Will ndiswrappers connect at those sorts of speeds?
