I do also have a plan of shifting my server into the cupboard under the stairs (need to clear it out and chop into one of the network cables that go up the stairs to get network access) so I guess I could move the AP from the living room to there, may speed things up.
Just checked and looked like it is connecting on 5G.
Discovered these which would be a pretty neat solution if I bolted it onto the back box where the ethernet comes out.
