AC3200 WiFi Cable Modem Router
Changes Not Saved
If the modem router does not save the changes you that make in the modem router interface,
check the following:
• When entering configuration settings, always click the Apply button before moving to
another page or tab, or your settings are lost.
• Click the Refresh or Reload button in the web browser. The changes might be saved, but
the old settings might be in the web browser’s cache.
WiFi Connectivity
If you are having trouble connecting to the modem router with WiFi, try to isolate the problem:
• The computer or WiFi device that you are using does not find the WiFi network.
This can happen for the following reasons:
- Someone pressed the WiFi On/Off button on the modem router, which turned off the
Wradios.
Check the 2.4 GHz and 5 GHz LEDs on the front of the modem router. If they are off,
press the WiFi On/Off button to turn the WiFi radios back on.
- Someone logged in to the modem router and disabled its WiFi radios or set up a WiFi
schedule.
In this case, pressing the WiFi button does not turn the WiFi radios back on. You
must log in to enable the WiFi radios. Use an Ethernet cable for a wired connection to
the modem router. Then log in and change the settings. For more information, see
Control the WiFi Radios on page 73.
- Someone logged in to the modem router and disabled its SSID broadcast. Your WiFi
network is hidden and does not display in your WiFi client’s scanning list. (By default,
SSID broadcast is enabled.)
To connect with WiFi, you must type the network SSID and password. For information
about how to enable the SSID broadcast, see
Specify Basic WiFi Settings on
page 69.
• You can find the WiFi network, but you can’t connect. Check the following:
- Make sure that your computer or device supports the security that you are using for
your WiFi network (WPA or WPA2).
- You are not sure what the WiFi password is.
The preset WiFi password is on the modem router label. If you changed it and do not
remember the new password, you can use a wired Ethernet connection to log in to
the modem router and view or change the WiFi password. For more information, see
Change the WiFi Security Option on page 71.
- The WiFi signal strength is weak in your location.
