What we’ve also discovered is once the issue starts it keeps happening until we reboot the switch.
Reboot AP fixes it for a very short period of time. Reboot Netonix and the issue either goes away longer. Or completely clears (if the rain has since passed). Next step will be swapping the Netonix out Monday for a Ubiquiti edgeswitch and making sure the ES is bonded to the building ground. > On Apr 20, 2019, at 14:39, <[email protected]> <[email protected]> wrote: > > Be fun to see if the problem changes when switching to a different antenna > and or transmission line. > > From: Matt Hoppes > Sent: Saturday, April 20, 2019 12:28 PM > To: AnimalFarm Microwave Users Group > Subject: Re: [AFMUG] Fwd: CAT5.
