Reconnecting to the Internet
When an internet connection has been broken, use the gprs_reconnect –t second command to
reconnect to the Internet. For example, enter gprs_reconnect –t 120 to direct the W406 to attempt
to reconnect to the Internet every 120 seconds. If you do not provide the time interval, the default
value will be 60 seconds.
Use the gprs_reconnect –h command for more details.
Disconnecting from the Internet
To disconnect from the Internet, use the gprs_disconnect command. After a few seconds, the
embedded computer will disconnect from the GPRS network. A notification message will NOT be
displayed.
