Make sure that your computer or mobile device is configured as a DHCP client (for
most devices, this is the default setting) so that the computer or mobile device can
automatically receive an IP address from the router. If you need to enable the DHCP
client on your computer or mobile device, restart the computer or mobile device,
and then verify the gateway address.
Changes are not saved
If the router does not save the changes that you make in the router web interface, 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 the old settings might be in the web browser's cache.
Troubleshoot WiFi connectivity
If you are experiencing trouble connecting over WiFi to the router, try to isolate the
problem:
• Does the WiFi device that you are using find your WiFi network?
If not, check the WiFi LED on the router. If it is off, log in to the router web interface
and check if the WiFi radio is enabled or disabled.
If you disabled the router's SSID broadcast, then your WiFi network is hidden and
does not display in your WiFi device's scanning list. (By default, SSID broadcast is
enabled.)
• Is there another WiFi router, gateway, access point, or extender broadcasting the
same network name as your router?
Make sure that any other WiFi broadcast devices are either turned off or using a
different WiFi network name.
• Does your WiFi device support the security that you are using for your WiFi network
(WPA3, WPA2, or WPA)?
• If you want to view the WiFi settings for the router, use an Ethernet cable to connect
a computer to a LAN port on the router. Then log in to the router, and select BASIC
> Wireless. (Be sure to click the Apply button if you change settings.)
