When you get the message is the computer always connected to the same wall
plate with the same cable? Swap cables and try again. Move the computer to
a different wall plate in a different room. Connect a different computer to
the original wall plate. Swap router/switch/hub ports around and see if the
problem moves.

Personally, I've installed Ethernet outlets all over my house too and wired
them to a patch panel in a closet in the basement with my DSL modem,
router, switch, and file server. The one problem I've had that seems
similar to yours was caused by my own clumsiness in preparing one wall
plate connection which caused a wire to break internally which caused
intermittent problems. Because the outlet was behind my home theater stand
finding the problem and fixing it took a long time and required nearly
standing on my head.
