• Your ISP may check for your computer's host name.
Assign the computer Host Name of your ISP account to the router in the browser-based Setup
Wizard.
• You have poor wireless coverage.
• Your ISP only allows one Ethernet MAC address to connect to Internet, and may check for
your computer’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 computer’s MAC address. This can be done in the Basic
Settings menu. Refer to “Manually Configuring Your Internet Connection” on page 3-7.
Troubleshooting Internet Browsing
If your router can obtain an IP address but your computer is unable to load any Web pages from the
Internet:
• Your computer 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 computer and verify the DNS address as described in “Verifying TCP/IP Properties” on
page C-6. Alternatively, you can configure your computer manually with DNS addresses, as
explained in your operating system documentation.
• Your computer may not have the router configured as its TCP/IP router.
If your computer obtains its information from the router by DHCP, reboot the computer and
verify the router address as described in “Verifying TCP/IP Properties” on page C-6.
Troubleshooting a TCP/IP Network Using the 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 your computer.
