The best solution, as installed here, is to run a CAT5 cable from an output
of the router to your son's room. It can, like mine, go outdoors if that
makes an easier cable run

Agreed. Just trying to get together the necessary parts. Having found
faceplates online, I went to the shed to find back boxes, and found
three - all different sizes. Are RJ45 modules with faceplates likely to
fit a standard 13 amp socket type back box, or a phone extension back
box or something else? The description, helpfully, does not mention the
size back box required. I could wait for the faceplates to arrive, but
that just causes another delay.
