Chapter 5: Configuring the Router
• E nable IGMP Proxy—IGMP (Internet Group Management Protocol) is used to manage multicasting on TCP/IP networks. Some
ISPs use IGMP to perform remote configuration for client devices, such as the modem router. The default value is enabled, and
if you are not sure, please contact your ISP or just leave it.
• Get IP with Unicast—A few ISPs‘ DHCP servers do not support the broadcast applications. If you cannot get the IP Address
normally, you can choose this option. (It is rarely required.)
• Set DNS server manually—If your ISP gives you one or two DNS addresses, select “Set DNS server manually” and enter the
primary and secondary addresses into the correct fields. Otherwise, the DNS servers will be assigned automatically from your
ISP.
NOTE: If you find an error when you go to a website after entering the DNS addresses, it is likely that your DNS servers are set up
improperly. You should contact your ISP to get DNS server addresses.
• Host Name—This option specifies the Host Name of the router.
