But my WiFi is just fine! - Divisions by zero

If it’s permanent, just run a cable to it
I tend to encounter a cable’s greates enemy: Walls in a rented appartment you can’t just drill through
Sometimes you can have great success using the wires in your walls, provided it’s in good nick and isn’t isolated. Try a powerline adaptor.
I run a 20m from my landline Box to my Router. In the hallway I route it behind the furniture. On doors I router it along the frame with transparent Self-adhesive cable older I got of Amazon.
