It seems to me that something other than the CAT-5 cable and/or router is at
fault. As a general rule, I have never found CAT-5 to be very sensitive to
RF ingress.
Are you using some kind of cheap CAT-5 or maybe something that has poor
quality connectors or wires that aren't twisted properly? What about a
name-brand router like a Linksys, D-Link, or AT&T wireless/wired
modem/router?
Network cable that isn't properly constructed with the required twisting of
wire pairs could introduce major RF problems.
I know all stations have different situations, but I have run high and low
power off and on for many years with numerous routers and computers and
CAT-5 cables located within a foot or two of transmitters and have never had
a problem with anything.
I think there is something going on other than CAT5/router issues. What
about the house wiring, your coax connector soldering, station grounding?
Do you notice any other RFI ill-effects other than the CAT5/router issues?
I am not trying to be critical but am simply looking for alternative ways of
dealing with the problem.

You could go all or mostly wireless. Use a wireless bridge to replace
the run of CAT-5 to the shack and plug the dumb hub into that so that
there are no long Ethernet runs.
