I have a Microsoft Surface Pro running Windows 8.1 and a desktop computer running Windows 8.1 on my home network. Both have their network connections set to "Private network," with file and printer sharing and network discovery turned on. I created a Homegroup on the desktop, and then tried to connect to it on the Surface.
I Ubuntu 14.04 and made all the changes on Samba to allow me to connect to my Windows Homegroup. Trouble is I can now either connect to the homegroup or the internet, but not both at the same time. I'm using Windows 7 on the other 2 PCs.
If I'm on the internet, and try connecting to the network it says "Unable to access connection.
