I just bought a new Intel Pro/1000 GT card for my desktop and was hoping for a plug&play experience but to my supprise it did not work at all.
Good part is Windows 7 (x64 Ultimate) found the card and installed driver version 184.108.40.206. But it refused to connect to my router. I even typed in a IP to force it but no luck.
Next i downloaded v15.4_CD from
i installed the drivers which showed to be older version (220.127.116.11) but i got some test utility with it which was good. I run the Hardware Diagnostic and everything passes so i'm confused what to do next.
Any tips is welcome at this point. By the wat i dont know how to go back to the "newer MS drivers". I tried to uninstall the existing one but it will just pop up back.
I took back the network card to my dealer and changed it to a D-link DGE-528T and it worked right away so i dare to say i had a bad intel network card.
Strange thing is that the hardware utility said it was fine. Anyway problem solved
