Try laying aluminum foil on top of hub.  That minimized problem for me years
ago for vhf contests.  I also moved hub from 2nd story shack to my basement.
Roof tower used here.  I tried to keep hub directly below my vhf beams.
Seemed to help.  You might want to change NIC speeds via software and see
what happens.

Perhaps not related but using software I changed my video refresh freq to
move birdies.  Easy to do.  Might be worth a try.

I have a home network with a cable modem connected to
a D-Link router, then from there to 1 computer and to
a wireless hub ( not on all the time) and to a Netgear
hub in my shack that supplies 2 computers there.

I am getting birdies from the Netgear hub. If I unplug
the dc the RFI goes away. The hub is about 4 feet from
the rigs. There is a ground wire on the hub. There is
cat5 cable to and from the hub.

Any ideas on how I can eliminate the RFI?
