I'm running XP Pro. My newly purchased DWA125 wireless USB adapter was working well after the installation with the original CD driver but then i noticed a newer driver version in the Dlink support page so i updated. But now it won't connect and it seems the Connection manager (tray icon with signal bars) is gone from both the tray and Start Menu. What happened and how can i use v1.20 as it is the newest of the two (the other being v1.00)? Thank you.
