Basic Setup
EtherFast Cable/DSL Router with 8-Port Switch
User Name and Password. Enter the User Name and Password provided by your ISP.
Heart Beat Server. This is the IP address that the Router has, when seen from the Internet. Your ISP will
provide you with the IP Address you need to specify here.
Connect on Demand and Max Idle Time. You can configure the Router to cut your connection with your ISP
after a specified period of time (Max Idle Time). If you have been disconnected 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. If you want
your Internet connection to remain on at all times, enter 0 in the Max Idle Time field. Otherwise, enter the
number of minutes you want to have elapsed before your Internet access disconnects.
Keep Alive Option and Redial Period. This option keeps your PPPoE-enabled Internet access connected
indefinitely, even when it sits idle. To use this option, click the radio button next to Keep Alive. The
default Redial Period is 30 seconds.
When you are finished, click the Save Settings button. Then click the Status tab, and click the Connect
button to start the connection.
Optional Settings
Host Name and Domain Name. These fields allow you to supply a host and domain name for the Router. Some
ISPs require these names as identification. You may have to check with your ISP to see if your broadband
Internet service has been configured with a host and domain name. In most cases, leaving these fields blank
will work.
MTU. The MTU (Maximum Transmission Unit) setting specifies the largest packet size permitted for network
transmission. Select Enable and enter the value desired. It is recommended that you leave this value in the
1200 to 1500 range. For most DSL users, it is recommended to use the value 1492. By default, MTU is set at
1500 when disabled.
