My vostro 1700 has vista. I recently upgraded from AVG 7.0 to AVG 8.0. My wireless works well at home and at work. However, visiting my son, my wirelss will not work at his house. He has netgear, similar to what I have at my home. I get the message - The settings saved on this computer do not match the requirements of the network. The onlhy thing that has changed since I last visted him in May (when it worked) is my upgrade of AVG.
