Just got my 128gb on Sat. Opened it, set up account, wifi personalization, every thing went fine with that. Then, before installing any apps I go to Windows update and install all 15 "important" updates. After install it says my Surface has to be restarted. Well after restart I have no wifi. My wifi adapter isn't even showing up under Network and Sharing. No option in Settings to turn wifi on just Bluetooth and Airplane mode. I then go Device manager it has a Marvell AVASTAR 350N. I updated driver and still nothing. I then go to Services and find the WLAN Service. I stop and restart that service then reboot. NOW WIFI IS BACK I thought... I went on thinking everything was fine until a couple of hours later something needed me to restart Windows I did just that and NO WIFI AGAIN. I follow the same steps as before and now wifi works again. I become curious and played around and after every restart my wifi is not working not even showing up in Network connection in "network and sharing center" but if I go restart WLAN Service and reboot there it is. This doesn't happen if I shutdown the Surface just "restart". So now I contact MS and right off the tech said this was a hardware issue that my Surface would have to be replaced. The Tech didn't even do any test or have me do anything. How did he know it was a hardware issue? Has this happened before? Anyway MS wants me to send them my Surface and when they receive it they will ship me out another one. I don't want to wait 2 weeks until they receive these in stock so I ask "how long will it take" he tells me 5-6 days and I should have my new one. I don't believe him since MS stores wont have them in until March 1st. Anyone got any ideas. Could this be a hardware issue? Or is it something I could fix software?
