Hello,
since the Surface update in Feb 2016 i also was unable to connect to eduroam in my Univeristy. First i tried the simple but costly solution of buying a USB-Dongle but even with this Dongle i couldnt connect with the failure" unnable to connect to network".
Now what did i do: ( in analogy to IrinaLiuberte)
- First delete the saved eduroam wlan profile. Do this in the Network Settings->Wlan Settings->Known Wlan Profiles ( something like that, i dont have an english Windows so im not quite sure)
[you also can try to delete it via cmd and netsh command but this didnt worked out for me]
- Go to your university website and look for the instructions to install a wlan profile manually. Just take all the settings given from your IT. In my case i had to use the install instruction for Windows 8.1 ( if anyone from the RWTH Aachen sees this post, use this! )
- Profit. Everything ist working fine again.
I hope Microsoft and/or Marvell will fix this annoying wlan bug soon. I read alot about people sending back ther surface devices cause they were unable to use eduroam, which makes the surface nearly useless in school or university.
Hope i could help!
