Anybody seen this before? I have the exact same setup at multiple locations and only this one is giving me this batch of errors 2-3 times a day with about 12 hours in between. I've tried a new cable to X1 and also forcing the connection to Full Duplex. Text Log below also:

    Just in case it happens to another person: It ended up being the cable that connected the main Frontier ONT to the TZ400. Frontier techs have been giving out these "CAT6" white flat cables that don't seem to be of high quality. Replaced with a high quality CAT6 patch cable and all errors and disconnects went away.

    Forgot to mention, X1 is connected to Frontier FIOS Modem/Router (Fiber Optic Internet Service).

    @joshuamarius I would suggest to test the connection on another free interface on the firewall to isolate if it is a hardware related.
