• Addressing Type - Choose the addressing type given by your ISP, either Dynamic IP
or Static IP. Click the Connect button to connect immediately. Click the Disconnect
button to disconnect immediately.
• MTU(Bytes) - The default MTU size is “1460” bytes, which is usually fine. It is not
recommended that you change the default MTU Size unless required by your ISP.
• Enable IGMP Proxy - IGMP (Internet Group Management Protocol) is used to manage
multicasting on TCP/IP networks. Some ISPs use IGMP to perform remote configuration
for client devices, such as the modem router. The default value is enabled, and if you
are not sure, please contact your ISP or just leave it.
• Connection Mode
• Always On - In this mode, the Internet connection will be active all the time.
• Connect on Demand - In this mode, the Internet connection can be terminated
automatically after a specified inactivity period (Max Idle Time) and be re-
established when you attempt to access the Internet again. If you want to keep
your Internet connection active all the time, please enter 0 in the Max Idle Time
field. Otherwise, enter the number of minutes you want to have elapsed before
your Internet access disconnects.
• Connect Manually - You can click Connect/Disconnect to connect/disconnect
immediately. This mode also supports the Max Idle Time function as Connect
on Demand mode. The Internet connection can be disconnected automatically
after a specified inactivity period (Max Idle Time) and not be able to re-establish
when you attempt to access the Internet again.
Note:
Sometimes the connection cannot be terminated although you have specified the Max Idle Time because some
applications are visiting the Internet continually in the background.
