Wireless-G Router for 3G/UMTS Broadband

The Setup Tab - 3G/UMTS Network

On this screen, you can configure mobile network settings and view mobile status information for the Router.
Some of these settings will be automatically configured by the Router and, in most cases, do not need to changed
unless you are instructed to do so.
Mobile Network Settings
Auto Connect. If this feature is enabled, the Router will automatically connect to the default HSDPA/3G/UMTS or
GPRS network when it powers on. The default is Disable.
Connect on Demand: Max Idle Time. You can configure the Router to cut the Internet connection after it has
been inactive for a specified period of time (Max Idle Time). If your Internet connection has been terminated
due to inactivity, Connect on Demand enables the Router to automatically re-establish your connection as
soon as you attempt to access the Internet again. If you wish to activate Connect on Demand, click the radio
button. In the Max Idle Time field, enter the number of minutes you want to have elapsed before your Internet
connection terminates.
Keep Alive Option: Redial Period. If you select this option, the Router will periodically check your Internet
connection. If you are disconnected, then the Router will automatically re-establish your connection. To use
this option, click the radio button next to Keep Alive. In the Redial Period field, you specify how often you want
the Router to check the Internet connection. The default Redial Period is 30 seconds.
Link Check. If Keep Alive Option is selected and Reset Data Card is enabled, you can use this option.
LCP. Use this option to set the time interval and missed replies for the receiving of the Link Control Protocol
response.
ICMP. Use this option to set the time interval and missed replies for the receiving of the Internet Control
Message Protocol response. To enable a new function:
1. The Router pings the Keep Alive Server1 every 30 seconds.
2. If the Router doesn't receive the ping reply, the Router will continue to ping the Keep Alive Server1 5
times.
3. If the Router receives the ping reply, then the timer and counter will reset. If two servers are specified, the
ICMP echo request timing will be interleaved equally between the servers. For example, if the interval is
20 seconds, server 1 will be sent its first echo request at 0 seconds, and server 2 will be sent its first echo
request at 10 seconds. Server 1's second request will be sent at 20 seconds, and so forth. If there are
more than three missed replies, then the connection will be terminated and restarted.
