I have 4 computers networked at home and all have Vista or XP. I just purchased a Laptop with Windows 7. Windows 7 sees the wireless but will not connect. I have Wep Security On. I have shut down the Wep security to see if that was causing the problem. I have upgraded the firmware that did not help nor did removing Wep security. Am I missing something here?
Go to Device Manager and locate the wireless adapter driver you installed, make sure it works well. In order to connect to wireless network successfully, the wireless adapter settings must match the wireless settings on wireless router.
