I recently reinstalled windows xp on my Dell Inspiron 640M laptop and also reinstalled all the drivers required. I find that I am not able to use LAN connection alone tough I am successfully able to use Wireless LAN. I also use Ubuntu linux on my computer in which I am able to use LAN for samba and FTP transfers.. Menas, the device is working fine. In windows, under network adapters, it doesnt even show my LAN.... What am I to do?
