The last time we had this kind of problem, we were using timing-cable sync. When we (1) switched to sync over power, and (2) added low-pass ferrite toroids, the problems went away.

We are using shielded cable with the drain wire grounded. Also, we are collocated with a 2-way transmitter. It runs at 400mhz. We confirmed today that it's not interfering because we still took on CRC's with it powered off.

We have verified that there is no visible water in the cable. The ends are not corroded at all.

    You've already checked for grounding issues and nearby 2-way
    transmitters around 100-150mhz?

        A while back there was a thread about issues running CAT5
        cables along the entire length of solid steel tower legs.

        We've run into a problem where we can't run 100baseT reliably
        on a couple APs. CRC errors will go away if we force the
        switch port to 10baseT. Interestingly enough, packet loss
        amplifies when it rains.

        Any help would be appreciated.
