RV50 reboots it'self

Some of our RV50’s (some are newer) reboot themselves and some don’t. Some seem to reboot hourly. Some reboot randomly. Some not at all. I’ve gone through the settings and and removed the settings that would cause it to reboot. Looking through the log I don’t see anything that might cause it to reboot.

Here’s the end of the log from the last modem that I checked.

Here’s what the start of a reboot looks like in the log:

Hi @mlloyd,

Please refer to the following ideas:

  1. From the log you provided, I see that you are not using the latest ALEOS software. Please download and install the latest ALEOS software then recheck whether the problem is resolved.
    Link the latest ALEOS software: https://source.sierrawireless.com/resources/airlink/software_downloads/rv50/rv50-firmware-list/#sthash.mEyDW8bw.dpbs

  2. Your RV50 has rebooted hourly, random reboot may be caused by Watchdog feature, please check again.

  3. Also, could you please share full log file on RV50 for analysis?

Thanks,

I finally received permission to share the log file from our IT Security team but, apparently new users aren’t allowed to upload. So I guess I have to have a lot of problems and posts before I can upload the file? That’s not going to happen.

I don’t know when it was disabled but I know the Watchdog was disabled. At this point, other than the reboots, I don’t think the modem is the problem.

Would you happen to have a clear definition of N in the following equation:

RSRQ = N * (RSRP/RSSI)

Thank you
