I have a similar setup, but with 5 computers following an 8 port switch
along with various net books, laptops, and smart TVs. there are 3 130'
runs of Cat 5 to the shop. 2 active and one spare. The two computers
are about 3 to 4 feet from a legal limit station and tied into it via
USB. Going the other direction there are 2 computers in the den along
with a ham station at the end of 2 10' Cat 5 runs. The 5th computer is
in my wife's office at the end of a 30' run. The printer is also there
via wireless.
The Cat 5 runs almost directly under the length of a 160 half sloper and
under the 40 meter sloping, center fed dipole. Running the legal limit,
I've had no interference problems "that I've detected.
That makes me wonder "why" you are getting into the network.
I'd be hunting for the source first, or at least while trying to
suppress it. Are you sure it's RF getting in via the Cat 5. You can
eliminate the problem disconnecting the Cat 5, but is it RF or a
grounding problem such as a AC or DC getting into the CAT 5.
The only problem with mine has been lightening. Wireless is finally
getting up to speed and after the lightening took out both my router and
switch last summer I'm strongly thinking of going all wireless.

OK, gang, I need some different help here.
I have a 4 port wireless router (Trendnet TEW-812DRU at the moment)
connected to our main computer and two others in the home, not including
the laptops that connect to it periodically.
I have replaced the router at least 4 times over the past year or two due to
the fact that RF from my ham station is getting into it through one or more of
the three CAT-5 cables I have connected to it.
I have installed several of those snap-on filters on all three of the CAT-5
cables which connect to it, and also on both ends of the DC power cable,
making seveal "loops" through each filter.
I still wipe out the router every time I get on the air. I have destroyed one
$169.00 router, and two less expensive ones, a TPNET and a Cisco.
The only solution I have come up with is to disconnect the CAT-5 cables (all
three of them) from the router each time I get on the air.
Has anyone here had a similar problem, and if so, what did you do to fix it?
BTW, one of my CAT-5 cables runs to the ham shack, where it connects to a
dumb 4 port switch...
This has become a giant PITA.
Any ideas?
