Ubuntu – Share wireless Internet connection through ethernet

connection-sharingethernetwireless

I want to share the wireless Internet connection on my desktop with my old laptop, through ethernet.

I have ticked the option "Make available to others" on both connections, on my desktop, but my laptop doesn't connect. Am I doing something wrong or is it a bug?

On the server computer:

  1. On the computer, which is connected to the Internet, click the network icon in the panel and go to "Edit Connections..." at the bottom of the menu.

    Edit Connection...

  2. Double click your Wired Connection (Leave your wireless connection untouched, the one connected to Internet and the one you want to share, as I understand).

  3. On the "IPv4 Settings tab", select Method: "Shared to other computers"

  4. Reconnect by clicking on the Wired Network, so it gets a new IP address. (The two computers must be connected by an ethernet cable for this step, so connect them now if you haven't already.)

  5. Click on "Connection Information" in the network menu and write down the IP address and network mask (in my case it was assigned 10.42.0.1/255.255.255.0 but I do not know if that will always be the case).

On the client computer:

  1. Go to "Edit Connections..." and assign a "Manual" Method. Assign an IP address on the same subnetwork (10.42.0.69 for example) and put the IP and network mask you wrote down in "Netmask" "Gateway" and "DNS servers"

  2. Reconnect to the network to let the new settings be assigned.

  3. Pat yourself on your back and surf away!!!
