Great unit! Great signal strength and reception. Supports W2K and WPA2 PSK security! This is a rare combination for a cardbus interface unit. I tried about 6 units before I got to this one.The interface program could be better! Its terse and clumsy. The BEST interface program I encountered was on my Parker Vision unit - but it only supported WEP security - and with the ISPs now spying on your network activity and reporting to the copyright gestapo - you want ALL the security on your access point you can get!
