I go out today with a 48v PoE injector and 6 Radio Shack ferrite clamps.
Swapping to 48v made no difference.
Adding a clamp just upstream of the PoE injector made no difference.
Adding a clamp just outside of the RooTenna made no difference.
Seeing no change, I put it back to the 18v PoE and went home to check if a
bridge had become misconfigured or something that would allow the Ethernet
to correctly setup at 10 HDX, but no data to pass.
I logged in and there the desktop was, starring me in the face from the DHCP
leases screen. I could ping it. I called over and they said the Internet
worked.
My only conclusion is that I needed to power cycle the RB once the ferrite
clamps were added.

Subject: [WISPA] Ethernet problems
I installed a customer in October and started having Ethernet problems in
March. I have an approximately 200' Ethernet run from the top of a TV
tower, to the house, and through the basement. I installed a Belden?
outdoor Cat5E cable, a Mohawk outdoor gel cable, a rope for future cable
additions, and an RG6 quad shield TV cable in a conduit.
Numerous times I cut off slack on both ends of the original cable (the
Belden). All that fixed the problem was turning off auto negotiation and
setting it to 100 HDX. A few weeks later the problems returned, and I set
it to 10 HDX. Now, maybe 6 weeks later the problem is back. I switched to
the Mohawk cable. I put on a different PoE injector and a different ECS
cable (PacWireless cable that provides an Ethernet jack on the outside of
the enclosure and has a 1' pigtail that plugs into the Mikrotik board.
Problem remains. The Mikrotik is getting power as it associates with my
tower and the two clients off an AP installed on the same board work just
fine. I tried different patch cables from the injectors to the
laptop\desktop.
I really don't want to pull 200' of cable only to have it not work again.
Does anyone have a good Ethernet tester I can borrow\rent? Not one that
just says if the pins make it (I had one of those and it said the cable was
fine), but one that is a bit more advanced. From my understanding, these
are $800 - $5k units. Someone close to Northern Illinois would be best.
I'm out of ideas.
