ParticipantI have monitored ping times during a reboot, and they are usually between about 50mS and 200mS without any obvious drops. Simiarly, traceroute didn’t show an obvious problem.
How can I disable the 4 minute reset?
ParticipantOk, that makes sense. How do I disable this 4 minute timeout? or change it to something longer? My internet connection is slow, so perhaps 4 minutes is overly optimistic.
OTOH, 4 minutes is a long time, so maybe there are connectivity problems elsewhere. What is the IP that is being checked? I’d like to monitor ping and traceroute to see if there is a correlation with the reboots (because I haven’t noticed any problems using other parts of the internet during these times).
ParticipantHow is it determined if the “net is down for more than 4 minutes”?
I’m polling the unit every 20-30 seconds over the LAN and that works fine with no gaps until the reboot happens. In the logs I pasted to the forum, you can see the timestamps:

{“data”:{ “id”:”11000103″,”type”:”1″,”detector”:”SBM20″,”voltage”:376,”cpm”:0,”temperature”:30.25,”uptime”: 15}}Poll at 02:32:26 . Reboot about 12 seconds later. Poll at 02:32:53.
There was no loss of LAN connectivity.
ParticipantI have removed the back plate so that the power cable seats easily. Still rebooting, so it’s not a loose connection.
I have also replaced the USB brick with another 5V 1A model. Still rebooting.ParticipantI don’t think it is related to the cable, since the box is not being moved, but it keeps rebooting. Here are some logs from the past day highlighting reboots:
