Links up, but nothing passes, not even DHCP.
Mikrotik's neighbor viewer (which is supposed to work even in the absence of
IP) can't see it.

Subject: Re: [WISPA] Ethernet problems
Can you define "Ethernet problem" a little more.
No link lights, intermittent link, no data, small packet data only,
intermittent data?
My first thought is bad connector or bad port on a device. I have seen
hub ports that will look fine, do small packets fine, but don't try to
move a lot of data. The port would just die, or jabber. Replaced the
module in the hub and all was well. I would assume the same can happen
with computers, SBC, switches, etc.

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.
