Changes Are Not Saved

If the modem router does not save the changes you make in the 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. 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 having 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.

For a device that is connected over WiFi, the WiFi network name (SSID) and WiFi security settings of the modem router and WiFi computer must match exactly. The default SSID and password are on the product label (see Bottom Panel Product Label on page 10).

•Does the WiFi device that you are using find your WiFi network?

If not, check the WiFi LED on the front of the modem router. If this LED is off, the WiFi radio might be disabled. For more information about the WiFi radio, see Manage the WiFi Radio on page 56.

•If you disabled the modem router’s SSID broadcast, your WiFi network is hidden and does not display in your WiFi client’s scanning list. (By default, SSID broadcast is enabled.) For more information, see Manage the Basic WiFi Settings and WiFi Security on page 49.

•Does your WiFi device support the security that you are using for your WiFi network (WEP, WPA, or WPA2)? For information about changing the WiFi security, see Manage the Basic WiFi Settings and WiFi Security on page 49.

Note: If you want to change the WiFi settings for the modem router, use an Ethernet cable to connect a computer to a LAN port on the modem router and then log in to the modem router.

If your WiFi device finds your network but the signal strength is weak, check these conditions:

•Is your modem router too far from your WiFi device or too close? Place your WiFi device near the modem router but at least 6 feet (1.8 meters) away and see whether the signal strength improves.

•Are objects between the modem router and your WiFi device blocking the WiFi signal?
