<br>I have found I had no choice but to use WPA-Personal on mine. I can't get the Linksys wireless card to connect with anything else. It's like the card is "hard-wired" for WPA-personal. I had set my router up for WEP 128Bit encryption but no mattter what I do the router & wireless card will -only- talk WPA-Personal.
