"
Why not get a wifi extender and place it nearest to his apt?""
I already had a 20 meter cable running around the side of th house as GF used to do home office from the apartment. Her system was medical and timed out if it was even fractionally slow. The only way it would work from home was ultra fast fibre broadband and cat5 cable. Wifi made it factionally too slow and it wouldn't work. So already had the cable and at the start I assumed it would be easy
