Until yesterday I've been successfully connecting Ubuntu 15.04 to WIN7 through ethernet;
Win7 was sharing internet and Ubuntu has a shared-folder you could access through Win7.
But now it isn't working anymore,
From the Network manager on windows I can see that the ethernet connection is
unidentified but I can't seem to troubleshoot in any way;
Ubuntu network manager
auto-ethernet option blinks but no connection is established.
I've tried configuring Samba workgroup and creating a home group on win 7 but without any success;
if I connect through wifi network directly to router (tplink 4g router) the shared folder on ubuntu is accessible from Win (I must be something related to eth connection)
