We've seen our share of odd SyncPipe/SyncBox issues. Sometimes the
receiver just gets confused and needs to be power-cycled. I've seen them
reporting miles of location inaccuracy until reset.
One issue I had with the SyncBox at multiple sites last summer is really
weird. Power would go out and the UPS died. Came back a couple hours
later. And then I got no sync and no data from them on all APs. Two of
the sites we're using the parasitic power and running one AP through it.
All of the radios were working perfectly fine, just no GPS data nor
sync. Power cycle it, nothing. Leave it alone and then a couple hours
later, bam, GPS sync and data comes back out of the blue. Even if the
receiver can't get lock, I should see some data on the AP's GPS status
pages. No idea what that's about.

We have a site that starts getting sync errors once or twice a day.
We've found if we power cycle the sync injector and the sync pipe, the
errors "go away" for a period of 3 - 6 weeks.
So that is our solution for the time being. We set up an alert when we
get sync errors. At which time we power cycle the sync injector/sync
pipe during off-hours (~~ 2AM-3AM), and wait for another few weeks.

The only issues I've heard like this are specifically related to
mounting in a bad location, and then the problem seems to come and go
just like you expect.
The units don't really have firmware on the unit itself, only in the
GPS module, and I can honestly say we've never had to update a
module in the field. I don't even know how to make that happen at
this point other than it can be done. The modules come from the
factory with our preloaded firmware, which never changes unless we
switch modules, which has happened once, the last time being at
least a year ago.
One caveat is that the newest syncboxes have been modified to work
with the 450i. So the radio driving electronics are slightly
different, even though the firmware is the same. This only is
relevant to units shipped in the last month or so.
If you can come up with the serial numbers of affected units that
might help in case something happened to a batch here (like some
undetected bad modules from our supplier)
The other thing to look at is if the status screen is really updating
on the radios. If the gps module doesn't supply data, the screen
stays the same.

We have been deploying sync box 12 units with Netonix switches
for the last 6-9 months with great success. However, several of
the syncbox12's we have deployed seem to loose and acquire sync
repeatedly until they are power cycled. This affects all the
customers on the tower during that time. Is there a firmware
version that fixes this? I'm not sure how to even update
firmware on a syncbox? The Sync status tab always shows that the
device is tracking 10 or so satellites but the device is not
passing sync on. In some other installations we have out there
they have never had any issues. It seems to be several that were
deployed about the same time that are doing this but I cant swear
to it. Forrest?? is there an easy fix to this or have you heard
about this from anyone else?
