>Description:

I decided to try the windows driver via ndis to see if I'd be able to connect to this AP at work ( http://www.freebsd.org/cgi/query-pr.cgi?pr=131153 ) and I am actually able to connect.  However the network performance is pretty bad, and the link keeps going from DOWN to UP and back DOWN again.  

Here's the output of 'ifconfig ndis0':

[ adamk at scroll - ~ ]: ifconfig ndis0
ndis0: flags=8843<UP,BROADCAST,RUNNING,SIMPLEX,MULTICAST> metric 0 mtu 1500

And the appropriate dmesg output:
