Troubleshoot Internet Browsing
If your modem router can obtain an IP address but your computer is unable to load any web pages from the Internet,
it might be for one of the following reasons:
The traffic meter is enabled, and the limit was reached.
By configuring the traffic meter not to block Internet access when the traffic limit is reached, you can resume
Internet access (see Unblock the Traffic Meter After the Traffic Limit Is Reached on page 243). If your ISP sets
a usage limit, they might charge you for the overage.
Your computer might 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 provides the addresses of one or two DNS servers for your use. If you entered
a DNS address when you set up the modem router, reboot your computer and verify the DNS address.
Alternatively, you can configure your computer manually with DNS addresses, as explained in your operating
system documentation.
The modem router might not be configured as the TCP/IP router on your computer.
For information about TCP/IP problems, see Troubleshoot Your Network Using the Ping Utility on page 291.
If your computer obtains its information from the modem router by DHCP, reboot the computer and verify the
modem router address.
Changes Are Not Saved
If the modem router does not save the changes that you make in a modem router web page, do the following:
When entering configuration settings, always click the Apply button before moving to another page or tab or
your changes are lost.
Click the Refresh or Reload button in the web browser. It is possible that the changes occurred but that the old
settings remain in the web browser’s cache.
