Hello everyone. I am new the forum. Hopefully the description of my problem is clear enough.:). I have 3 computers connected via Ethernet in 1 room. 1 laptopn with Windows 7 Ultimate, 1 laptop with Ubuntu 12.04 and 1 PC with Windows 7 Ultimate. Both laptops use their own independent WiFi adapters for internet, but the PC does not currently have an adapter. I built it strictly as a gaming rig and do not intend to use it for daily web surfing. I do not use the Ubuntu laptop for my internet very much, so I want to use the WiFI connection on that laptop and somehow pass it through my local network to the PC.

The WiFi router is on another floor and the LAN is completely separate. Bridging the WiFi and Ethernet adapters is out because it funkifies my network connections, and I am unable to access all the machines and synergy gets very confused.

What is the best way toI go about forwarding the internet connection from my Ubuntu laptop to the PC?

Thank you very much in advance.

You need software or hardware that will allow you to bridge the LAN and WLAN adapters on the laptop. Windows will certainly let you share the laptop's Internet connection, but only on a per-adapter basis. In other words, if you shared the laptop's LAN adapter, the desktop will need to connect to it with a network cable.

Unfortunately, I couldn't tell you if Ubuntu natively supports software bridging and I've not used hardware-based ones myself.

If I read your connection diagram correctly, you want to share Internet received by WiFi adapter of the Windows laptop over the lan. If so - enable Windows' Internet Connection Sharing, then put switch to that laptop' LAN port. You will have double NATting in that config.

Option 2: Some (most?) WiFi routers support "Bridge" mode, where they do just that - bridge between WiFi and LAN.

BTW - what software you used to draw your diagram?

I wish to use the Internet received by the wifi adapter of the Ubuntu laptop. How would I go about double NATing? Keep in mind that I cannot change the IPs of the adapters or I will looses network connectivity between all my computers.

I used GIMP to make the diagram. I nabbed some icons from Google for the illustration:)
