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).

    Network Connections Dialog

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

    Editing Wired Connection

  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 but I do not know if that will always be the case).

    Connection Information

On the client computer:

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

    Editing Client Wired

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

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

    The first 4 steps were enough in my case (Ubuntu 14.04). What is wrong with the automatic assignment (DHCP)? Why are you manually reassigning it?

    I've done this dozens of times. Just use auto instead of manually assigning it on the non-server computer and don't forget to leave ports 67, 68, 52 and 53 open for dhcp and dns access. Also, don't forget that ufw blocks incoming, so you will have to either disable it on the server computer or set the rules accordingly.

    This solution worked fine for me. The only think I would like to add is: If the method "Shared to other computers" is not listed on the configuration menu from IPV4 tab (this was my case running Ubuntu 17.10 with default Gnome interface) you can start the network settings from the command line with nm-connection-editor. As seen here.

    Wow it took me forever to configure the according netplan on my client because I forgot to set the gateway to the hosts IP-address... So if anybody can use ssh but fails to share the internet connection: Remember your gateway to be your hosts IP!

    This answer is still useful! But it would be so much more useful if it were updated to reflect the current GUI - or even better, using the CLI tools to do the configuration.

With network-manager in KDE in 2022 I don't need to do anything too complicated: just create a new shared connection (default configuration works fine):

  1. open the configurations:

enter image description here

2.add a new connection

enter image description here

  1. select "Wired ethernet (shared)" (or similar), give it a name like partageinternet, and save (no need to configure it):

enter image description here

  1. Then, plug you ethernet cable to your other computer (tested with a rasperry). A new entry should appear in the Network Manager menu to start to share the previously created connection. Actually if the entry is not visible (in my case it did not appeared the first time, not sure why), you can force NM to start it:
$ nmcli connection show
partageinternet …
$ nmcli connection up partageinternet

That's all! The other computer should automatically connect.
