iirc, it's always done this.  It's one of my spare wifi backhauls that
spends most of it's time in a cardboard box waiting for a task,
collecting dust.  Kinda like the toys in Toy Story.

I pulled it out a month or so ago and the behavior started.  It had
4.2.8 on it at the time.  I upgraded to latest stable a few weeks ago
(v4.8.6) and I'm getting the same issue.

When I originally set it up, it didn't run long enough for me to recall
if the issue occurred.  Best I recall, that was with v4.2.8.

thx,

Jason.
