Wireless-G ADSL Home Gateway
RFC 2364 PPPoA
Some DSL-based ISPs use PPPoA (Point-to-Point Protocol over ATM) to establish Internet connections. If you
are connected to the Internet through a DSL line, check with your ISP to see if they use PPPoA. If they do, you
will have to enable PPPoA.
• User Name and Password. Enter the User Name and Password provided by your ISP.
• Connect on Demand: Max Idle Time. You can configure the Gateway to disconnect 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 Gateway to automatically re-establish
your connection as soon as you attempt to access the Internet again. To use this option, click the Connect
on Demand 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: Redial Period. If you select this option, the Gateway will periodically check your Internet
connection. If you are disconnected, then the Gateway will automatically re-establish your connection. To
use this option, click the Keep Alive radio button. In the Redial Period field, specify how often you want
the Gateway to check the Internet connection. The default Redial Period is 20 seconds.
Bridged Mode Only
If you are using your Gateway as a bridge, which makes the Gateway act like a stand-alone modem, select
Bridged Mode Only. All NAT and routing settings are disabled in this mode.
Optional Settings (required by some ISPs)
• Host Name and Domain Name. These fields allow you to supply a host and domain name for the Gateway.
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, you can leave
these fields blank.
• MTU and Size. The MTU (Maximum Transmission Unit) setting specifies the largest packet size permitted for
network transmission. Select Manual and enter the value desired in the Size field. It is recommended that
you leave this value in the 1200 to 1500 range. By default, MTU is configured automatically.
Network Setup
• Router IP. The values for the Gateway's Local IP Address and Subnet Mask are shown here. In most cases,
keeping the default values will work.
