2 PCs & 2 printers upstairs and a laptop in an office at the rear of the
building.
Everything else is plugged in.

The laptop in the office, fair enough, it is close to a wall as is the
router but on the other side such that the signal would be travelling
through the length of the wall, and there's a metal gate, i'll let that
one off and I have run a cable.

One of the PCs upstairs is grand, the other is a nightmare, despite
being only about 5m from the router albeit with a brick wall and a
ceiling between, and a bunch of flourescents dotted about.
There may well be foam backed boards on the ceiling too.
It will work adequately on one side of the room, not at all on the other.
