The Edimax reciever doesn't require to plug in during installation, but Windows still says it can't find a proper driver to run it. In "Device and Printer" window (somewhere in the control panel) the system reconize the reciever as 802.11 n WLAN. I tried to manuelly install the driver in Device Manager, but Windows always says that the driver it has (which is from Microsoft) is the newest one and no action seemed to be made by Windows.
The Tenda reciever though, requires to have the reciever plugged in during installation or it won't move on, but when I plug in the reciever and begin the installation, the prograss is stuck at zero and cannot prograss for minutes. When I plug the reciever out, the installation prograsses and completes. But when I plug the device again, the software that runs the reciever cannot detect the reciever
Is it possible that there are some setting in the BIOS that caused such a problem (in particular, when an unknown device is plugged in, I can't install the driver in question, or to boot or shut down)?
One more note: the system is updated from Windows XP Pro SP3 to Windows 7 Ultimate, I still haven't touched the old hard drive which have the XP in it. Could it be a problem?
