Question: Why does my modem reset every 10 minutes (or other time)?
Answer: There are a number of processes in the VIP4G 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 VIP4G 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 VIP4G will monitor a local device, if that device is not present the
VIP4G may reboot. Network > LocalMonitor.

Question: Why is the data usage on my modem so high?
Answer: Although it is impossible to answer that question without more detailed information about your
modem, and the devices/application you are using, there are a number of things to keep in mind:
1. Always setup and configure a Firewall on the modem, this is especially important if the modem
is using a publically accessible IP address.
2. Always change the default user/passwords.
3. Turn off any services that are not needed, such as GPS, Comports, SNMP, SSH, anything not
being used specifically in your application.
4. Use the Data Usage alerts to keep informed of daily and monthly data usage of the modem to
avoid surprises once the data bill arrives.
