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
210). 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
257.
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 on 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.

Troubleshoot the WiFi Connectivity

If you are experiencing trouble connecting over WiFi to the modem router, try to isolate the problem:
•
Make sure that the WiFi settings in your WiFi device and modem router match exactly.
