I have a PC with windows 7 professional. While at college I installed a series of drivers that came with wireless dongles so that I could pick up wi-fi on my PC. Ever since I installed these drivers I have not been able to map any network drives. I've gone into the control panel and uninstalled all network drives and re-installed the defaults but that has not fixed anything. Does anyone have any out of the box suggestions, because I believe I have tried every conventional fix other than reformatting the whole drive.
