+ 1 Votes Did you download the correct driver from the manufacturer website? wizard57m-cnet Moderator 1 year ago You might find a more "compatible" driver from the manufacturer's website, once at the manufacturer's website, search for something like "support" or "drivers", "software/firmware" updates. Be sure the driver you download matches the specific wifi adapter model. The other suggestion would be to download the driver, save it somewhere (Desktop, My Documents), then completely uninstall the old device driver before installing the one you download from the manufacturer. When you uninstall the driver, if it goes well, you should get a notice from Windows that "new hardware has been found" with a description...follow the prompts to add the device, and when it gives you the options of where to find the driver, choose "Have disk" and then browse to the driver you saved.
