I was reading this thread, and I had a thought (scary thing!, LOL), it
it possible that inside the conduit, there is a rough edge (maybe the
edge of a junction box if you are not using LBE's?) that scraped off the
outside covering and you now have exposed wires that you can not see?.
Perhaps the wires are exposed somewhere and a little bit of moisture
(even humidity) got inside the conduit and is causing the errors?. It
would really be a long shot, as this rough edge would have to scrape off
the shielding from both CAT5 cables, but I have seen stranger things. I
have also had problems in the past from bad ballasts in flourescent
lights. Even if they are a few feet away, they make all sorts of strange
things happen. Another place to look is bad power supplies. I installed
a radio at a customers home one time that had a power supply. It made
noise thru every computer speaker. As soon as you unplugged the power
supply, the noise went away. It also would allow the radio to boot up,
but the ethernet was just screwy, sometimes passing packets, sometimes
not. Good luck in your search!. Tim

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.
