Ping an IP address to test connectivity to see if you can reach a remote host.

•

Perform a DNS lookup to test if an Internet name resolves to an IP address to verify that the 
DNS server configuration is working.

•

Display the Routing table to identify what other modem routers the modem router is 
communicating with.

•

Reboot the modem router to enable new network configurations to take effect or to clear 
problems with the modem router’s network connection.
