With respect to range, throughput, WEP and MAC security, this card was right up there with my Linksys WPC11v3 and Orinoco Gold cards. It would not, however, stay connected to my WAP when SSID broadcasting was disabled. Friends' Netgear, Siemens and Proxim cards don't have this problem.Beta drivers from TrendWare did not resolve the SSID issue. Techs there claim the card works without SSID broadcasting using their WAPS.
My WAP is based on Atmel v1.1 hardware running 1.4h.3 firmware which is basis for many WAPs from Linksys, Netgear, D-Link to just name three.
For a price in the $...range, you will not go wrong with this card. It's a screaming deal; 1/2 to 1/3 the price of cards with similar performance. It was up there in the 11 mbps range even at 100' from my WAP, even with WEP enabled.
But keep in mind that it may not communicate in WiFi networks that don't broadcast the SSID. If you know what that means, you should be concerned. If you have no clue as to what SSID broadcast is, buy this card and save some bucks.
