I'm guessing this is really easy to do but i tried and it didn't work. I have a desktop running Mint 20 and a laptop running Mint 19, I think. I don't have a wifi card in the desktop so it needs to be plugged in to the router. I don't want to be running ethernet cables all over the house so I was wondering if I can plug the desktop into the laptop with an ethernet cable and use the wifi that way. It's not a permanent solution but I don't want the desktop plugged into internet all the time anyway, just the odd time and I can bring the laptop over to it.

Like I said I did try by plugging the cable in and the desktop did try to connect but it failed unfortunately. I'd say I need to give it permission or something. Anyway thanks in advance!

Honestly, if it was me I'd spend the €16 in Argos on a USB WiFi adaptor for the desktop. (https://www.argos.ie/webapp/wcs/stor...hTerms=3389780)

Plug it in, configure it, forget it. Saves messing around with laptops, cables, power supplies for the lappy, desk space, blah, blah, blah!

Thanks, I might go that way. I did have a TP-Link adapter in the desktop but I couldn't get it to work. It actually caused Mint 20 to crash every time I turned the computer on. How easy are the USB ones to configure?

Haven't used one in years to be honest.

breadbin,

This TB Ralink 5370 USB Wifi Dongle appears to work according to the feedback from Linux users:

Mint 19 should be capable of Internet connection sharing.

Using the Network Manager applet look at the settings for your wired connection under IPV4 and see if there is a "shared to other computers" selection. There should also be an option setting to enable DHCP.

I agree that a USB wireless adapter would be a better way.

Do a web search for "use linux as a router."
