Option Settings (Required by some ISPs)   
This section is common for all the Internet Connection Types. Some of these settings may be required 
by your ISP. Verify with your ISP before making any changes.   
 
Host Name: Some ISPs, usually cable ISPs, require a host name as identification. You may need to 
check with your ISP to see if your broadband Internet service is configured with a host name. In most 
cases you can leave this field blank.   
Domain Name: Some ISPs, usually cable ISPs, require a domain name as identification. You may 
need to check with your ISP to see if your broadband Internet service is configured with a domain 
name. In most cases you can leave this field blank.   
MTU: MTU is the Maximum Transmission Unit. It specifies the largest packet size permitted for 
Internet transmission. Select Manual if you want to manually enter the largest packet size that is 
transmitted. To have the Router select the best MTU for your Internet connection, keep the default 
setting, Auto.  
Size: When Manual is selected in the MTU field, this option is enabled. The recommended setting for 
this field is 1500 (standard MTU size on Ethernet media).
