Just before I re-carpeted the house, I managed to lay a whole reel of
CAT5 (1000 feet) under the floorboards, so there are multiple cables
from more or less everywhere to everywhere else - £10 well spent, I
think


If you are going to lay cat5, I'd not lay it "from more or less
everywhere to everywhere else ". I'd lay it from "more or less
everywhere" back to one central point.

UTP networking is essentially a star architecture, not a matrix.

Ah yes, but you're assuming I'd use it just for networking

I ended up laying it everywhere just to use it up

Once you have 10 cables from modem to router and from modem to main
computer, router to main computer and router to upstairs points, you're
just using up cable to allow for every contingency
