  MTU  Size  -  The default MTU size is “1480”  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 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. 
  Primary DNS/Secondary DNS - 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.
