Had an issue earlier in the week where I had to take my SP3 into a Microsoft store. They exchanged it with a new one. Brought it home, set everything up, working great. Get into work this morning and having issues with the dock. It powers fine, USB works, etc... but I have no ethernet. I have: -Unpowered and powered the dock -Removed the SP3 and reseated it multiple times -Rebooted several times -Checked Windows update -Downloaded the latest SP3 drivers msi and installed it I had a firmware update go through yesterday but I wasnt on the dock when it installed. Im pretty sure with my last SP3 I rememeber there being a specific dock update that I saw in windows update but I could be losing my mind. I did see some ethernet adapter downloads at the link below but when I download them they arent installable files so I dont know what to do with them. http://www.microsoft.com/en-us/download/details.aspx?id=38826 Any ideas? I finally have this set up and REALLY dont have time to refresh windows and start over. I already lost a day of work when I had to go down to the MS store.
