Router WiFi -> Laptop ->(cable)-> Desktop

[Atsza]

As the title says I am trying to get my internet to my desktop. I can't run a cable directly form the router due to doors.
I googled how to turn your laptop into an access point and it told me that I should enable sharing under Wifi properties -> sharing -> enable sharing to internet to other computers.
This setup has worked before but the last two days I have not been able to receive internet on my desktop.
I have tried multiple ways of "fooling" one of the components. Turning the sharing on/off, order of plugging the cable in, restarting computers but nothing works anymore.

Does anybody have experience how to do this consistently?
the laptop is removed from the network daily because it is my laptop that I use at school.

you can use a powerline setup. Cheap to buy, easy to install, get wired speeds anywhere in your house.

Or use the conventional method - - buy a USB WiFi adapter (or a PCI wireless card) for your desktop PC and connect wirelessly direct to your wireless router just like you do with your laptop.

However, that method (using WiFi) will give you slower transfer speeds compared to keith12's suggestion of using a pair of powerline adapters.

I did that but before moving in I didn't know the location of the router. I got 100 percentile speeds at my old house but at the new place there are 2 walls and a chimney inbetween. wifi at the new place where my desktop is 1mb/s / 1 mb/s. If I move to a different location with about the same length to the router but nothing inbetween I get 19.2mb/s and 5mb/s. And the room my computer is the only room which doesn't have a wall ethernet hole.

Then give powerline adapters a try as suggested by keith12.
