i just reformatted my dell xps m140, and since it refuses to take any of the wifi drivers on the dell website.
i installed chipset, and updated the bios, still not working. it worked fine with windows vista and XP, but with 7 it does not work.
i have also have a dell inspiron 2200, which has almost identical hardware, and that works fine with win7.
someone else was having the same issue but there has not been any update on it.
thanks in advanced, - joey
