Troubleshooting

If your router is still unable to obtain an IP address from the ISP, the problem may be one of the 
following:
Your ISP may require a login program.
Ask your ISP whether they require PPP over Ethernet (PPPoE) or some other type of login.
If your ISP requires a login, you may have incorrectly set the login name and password.
Your ISP may check for your PC's host name.
Assign the PC Host Name of your ISP account as the Account Name in the Basic Settings 
menu.
Your ISP only allows one Ethernet MAC address to connect to Internet, and may check for 
your PC’s MAC address. In this case:
Inform your ISP that you have bought a new network device, and ask them to use the router’s 
MAC address.
OR
Configure your router to spoof your PC’s MAC address. This can be done in the Basic Settings 
menu. Refer to 
.
If your router can obtain an IP address, but your PC is unable to load any web pages from the 
Internet:
Your PC may not recognize any DNS server addresses. 
A DNS server is a host on the Internet that translates Internet names (such as www addresses) 
to numeric IP addresses. Typically your ISP will provide the addresses of one or two DNS 
servers for your use. If you entered a DNS address during the router’s configuration, reboot 
your PC and verify the DNS address as described in 
Alternatively, you may configure your PC manually with DNS addresses, as explained in 
your operating system documentation.
Your PC may not have the router configured as its TCP/IP gateway.
If your PC obtains its information from the router by DHCP, reboot the PC and verify the 
gateway address as described in 
.
Troubleshooting a TCP/IP Network Using a Ping Utility
Most TCP/IP terminal devices and routers contain a ping utility that sends an echo request packet 
to the designated device. The device then responds with an echo reply. Troubleshooting a TCP/IP 
network is made very easy by using the ping utility in in your PC or workstation.
