Whentrying to connect to the router on my MAC PRO with windows 8.1, I keep getting error 651. I have tried all of the fixes I can find on the internet. I am led to believe this is a ISBN driver problem and am told to download the latest driver. Of course I cant do this because I cant connect. I have another Windows dedicated computer. Is there any way to download this to disk and then to windows on my Mac? What a mess. I have spent two days trying to connect.
