Question:

Why does my modem reset every 10 minutes (or other time)?

Answer:

There are a number of processes in the IPn4G that ensure that the unit is communicating at all
times, and if a problem is detected will reboot the modem to attempt to resolve any issues:

1. Traffic Watchdog - Detects if there is any Wireless Traffic between the IPn4G and the
Cellular Carrier. Will reboot modem when timer expires unless there is traffic. Carrier > Traffic
Watchdog.

2. Keepalive - Attempts to contact a configured host on a defined basis. Will reboot modem if
host is unreachable. Enabled by default to attempt to ping 8.8.8.8. May need to disable on
private networks, or provide a reachable address to check. Access via Carrier > Keepalive.

3. Local Device Monitor - The IPn4G will monitor a local device, if that device is not present the
IPn4G may reboot. Network > LocalMonitor.
