I should have specified that the internet source was is not DSL, but coax.
Is it the Ethernet switch or the modem that's got the problem?
What are you calling a "router?" I've most often seen that name applied
to a WiFi base station.
The LAN cables are unshielded Cat 6, and there are lot of them. Putting
2 inch cores on each of them is impracticable, so I'm looking for a
modem with less inherent susceptibility. Problems occur only when I'm
transmitting on 160.
It may be the easiest solution is to disconnect all the LAN cables during
contests, and just use WiFi.
That may or may not fix it, but by all means try it. If you haven't
already done so, try a serious choke tuned to 160M on the coax at the
modem and the power supply for the modem.

Years back I used a K-COM noise filter that worked well. Not sure if they're
made anymore.

Despite a ton of ferrite cores on all the cables, my router fails every time I
transmit on 160. I'll admit that RF levels are high, as my shunt-fed tower is
only about 20 meters away from the router, and some of the ethernet cables come
within about 10 meters of the tower. Has anyone found a router that doesn't
have this problem?
