I know this has been discussed before and I did search but I can't find the exact problem. I remember one of the issues was with HPs and indeed my daughters would not connect, however, she has a new HP and there are no issues. Now my sons work Lenovo, XP can not connect to my network if I have WPA2 Personal, AES enabled, security disabled - no problem. This laptop is only a few months old and his previous one had the same problem. Could it be an issue with his Co. VPN? Thank You!
