Proxim 8800-FC

This card was sold as a b/g upgrade kit for AP-2000s. Though it was never intended to be used as such, it works in Windows with Atheros' reference drivers (you must manually install and select a device).

It appears to have been manufactured by Ambit / Foxconn / Hon Hai (U59H001.01). Uses an uncommon combination of AR5212 + AR5111 + AR2111 for 802.11b/g only. .. and although it shares a great resemblance to the popular Proxim 'businessman' PC Cards, the receive sensitivity on this model seems to be notably lower.
