[AFMUG] ubnt devices intermittantly stop responding to pings

[TJ Trout]

I did a little searching on the forum and I can't see to find anyone who
has ran into this issue, I'm noticing that many of my ubnt devices will
randomly stop responding to pings but the web ui and radio keep passing
traffic normally? within an hour the radio will start responding to pings
again like it never even happened... No power cycling or any intervention
required.
