troubleshooting device resets

Question

Hello all,

Looking for some help. a few times the WR44 has reset. Checking event logs we see:

12:00:12, 30 Aug 2011,Power-up[]
12:00:12, 30 Aug 2011,GPRS using SIM 1 (present)
12:00:12, 30 Aug 2011,Eventlog Counters Reset
07:24:52, 30 Aug 2011,WEB Login OK by admin lvl 0

So looking for some tips on how to figure out what is happening. NB there were no power issues.

Thanks,
Matt

Answer 1

How do you know there are no power issues? Different devices will have different sensitivities to power spikes or voltage sags.

It could also be related to surge/grounding issues if you have serial devices attached. I have never seen/used the WR44, but I believe its serial ports are NOT optically/galvanically isolated, so serial ground problems could also cause it to reset itself.
