Setup > Keep Alive
Keep Alive lets you prevent the wireless network from closing your data connection during
extended periods of inactivity by having the unit ping a DNS address at set intervals.
Keep Alive: Select Enable to enable this feature. Select Disable to allow your connection
to terminate when the DHCP lease expires (usually 24 hours).
Ping Address: Select DNS1 to use the assigned address. To enter an alternate address,
select User Defined and then enter a ping IP address in the User Defined Ping IP
Address field that will appear.
Ping Interval: Select an interval for pinging. (Default is 120 seconds.)
