Troubleshoot Internet Browsing
If your cable data gateway 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:
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 cable service provider provides the 
addresses of one, two, or three DNS servers for your use. If you entered a DNS address 
when you set up the cable data gateway, 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 cable data gateway might not be configured as the computer’s TCP/IP cable data 
gateway.
If your computer obtains its information from the cable data gateway by DHCP, reboot the 
computer and verify the cable data gateway address. 
For information about TCP/IP problems, see 
161.
Changes Not Saved
If the cable data gateway does not save the changes you make in the cable data gateway 
web management interface, do the following:
When entering configuration settings, always click the Apply button before moving to 
another screen or tab, or your changes are lost. 
Click the Refresh or Reload button in the web browser. The changes occurred, but the 
old settings might be in the web browser’s cache.
WiFi Connectivity
If you experience trouble connecting over WiFi to the cable data gateway, try to isolate the 
problem.
Does the WiFi device that you are using find your WiFi network?
If not, check the 2.4 GHz LED or 5 GHz LED (or, for model N450, the WiFi LED) on the 
front panel of the cable data gateway. If a LED is off, the corresponding WiFi radio in the 
cable data gateway is off. For information about turning on the WiFi radio, see 
109. When the WiFi radio is turned on, the LED starts blinking green 
or lights solid green.
If you disabled the cable data gateway’s SSID broadcast, your WiFi network is hidden 
and does not display in your WiFi client’s scanning list. (By default, SSID broadcast is
