Here is my setup. I have a Windows 7 PC connected to internet over WiFi and would like to share this with Ubuntu (no router involved). Also, Ubuntu i use it for tethering for mobile data (whenever WiFi is down) and would like to use this connection from windows 7. I know hotspot is an option to get the mobile device to share the internet connection, but was looking if there is a way to with out this. Does anybody know of such a setup?
Sorry for taking a bit to be back:
Share from Ubuntu
Then all you need to do is connect an Ethernet between Ubuntu and whatever computer/object with an Ethernet that needs connectivity. Should have all the other settings already in place for that.
