If you want to do some advanced configurations, please click the Advanced button, and the page
shown in Figure 4-9 will then appear:
MTU Size - The default MTU size is "1492" bytes, which is usually fine. It is not
recommended that you change the default MTU Size unless required by your ISP.
Service Name/AC Name - The service name and AC (Access Concentrator) name, which
should not be configured unless you are sure it is necessary for your ISP. In most cases,
leaving these fields blank will work.
ISP Specified IP Address - If your ISP does not automatically assign IP addresses to the
router during login, please click "Use IP address specified by ISP" check box and enter the
IP address provided by your ISP in dotted-decimal notation.
Detect Online Interval - The router will detect Access Concentrator online at every interval.
The default value is "0". You can input the value between "0"and "120". The value "0" means
no detect.
DNS IP address - If your ISP does not automatically assign DNS addresses to the router
during login, please click "Use the following DNS servers" check box and enter the IP
address in dotted-decimal notation of your ISP's primary DNS server. If a secondary DNS
server address is available, enter it as well.
Click the Save button to save your settings.
