My fix for this type of problem was to start using shielded cat5 with built in drain wire.
Hook the drain wire at the radio ground, and at the other end bond the drain wire to an earth ground. This stops the surges from ever getting into the wire. I have not lost an Ethernet port since I did this, even in a location that had killed 5 Ethernet cards before... Hope this helps...
