Recently I tried setting up the laptop computer in my gameroom to share its wireless Internet connection via Ethernet. That might be a little confusing, so allow me to explain.
What I wanted to do was plug my Xbox into my laptop and have it access the Internet(XBL). When I tried to search for how to share your wireless connection in this way, I mainly found a series of cryptic instructions – often revolving around the excellent Firestarter firewall – none of which worked for me.
But don’t worry – there is a simple way to do this, and I figured it out accidently while following all the various sets of instructions I found. As a service to the Ubuntu community, here is a simple step-by-step guide on how to share your wireless connection via your ethernet port in Ubuntu.
[b]Step 1: Edit Network Comnections[/b]
On your top panel, beside your clock and your system icons, you’ll see your network indicator. When you’re connected to wireless, it features bars telling you the stength of your network connection. Right-click this, then click “Edit Connections.”
Step 2: Edit the ethernet settings
In the window you just opened, make sure you’re looking at the “Wired” tab. Then select the “Auto eth0” connection and click “Edit.”
Alternatively you can create a new connection by clicking “Add” but I found it simplest to just change the default. Just be sure to remember that you changed this setting in case you ever want to use your Ethernet port to access the Internet again, because you will have to change it back to do so.
Step 3: Set to Share
Here’s where stuff starts to look confusing, but don’t panic: it’s not that bad. Click the “IPv4 Settings” tab. Beside the word “Method:” there is a drop-down menu that allows you to pick the manner in which your Ethernet device connects to the network. Select the “Shared to other computers” setting.
Restart your computer. Assuming everything applied correctly, you should now be able to connect any computer or gaming device to the Internet via your laptop’s Ethernet port.
