Firstly, using a switch instead of a hub is absolutely a good idea, if you have
more than 3 computers connected. A hub is exactly like a party line phone
system (do you know anyone who can reminisce about party lines?). As cheap as
switches are, I cannot imagine why anybody would use hubs.

Unfortunately, a switch, by itself, probably won't solve a connectivity problem
like yours. Since you have multiple computers in your house, you're going to
have to move things around a bit to isolate your problem.

A connectivity issue like yours has 3 possible causes:
1) Component A (ie the hub).
2) Component B (ie the cable).
3) Component C (ie the computer).

You're going to have to swap things around a bit, connect the problem computer
in place of one of the other computers (IOW use a known good cable and hub port
to connect the problem computer). Then connect a good computer to the cable /
hub port that's involved in the problem. And see where the problem shows up.

How did you decide that the original hub was bad? Have you considered getting a
router, and eliminating the "host" issue altogether?

Also, how are you running these cables up and down the stairs without
interference between people and cables? Are they store bought cables with
pre-assembled connectors? Or custom length cables with connectors attached
on-site? How do you protect the cables from damage?
