If you can see other networks, but not the network name for your FX4100 cellular router:
Reason: The default multi-mode settings on your router work for most Wi-Fi clients, however, some older devices require that you set one of the Wi-Fi bands to support older BGN standards.
Solution: Set your 2.4 GHz band to Wi-Fi 4802.11 bgn:
1. Access the Admin web UI and navigate to Wi-Fi > Settings. Under 2.4 GHz Band Settings, use the drop-down to change the Wi-Fi Standard to Wi-Fi 4802.11 bgn.
NOTE: This allows older devices to connect on the 2.4 GHz band but leaves the 5 GHz band in multi-mode to allow newer devices the fastest available connection.
2. Click Save Changes. Your router will reboot, and the network name should be visible on all devices.
If you can see the network name, but cannot connect a device to your FX4100 cellular router:
Reason: The default network security settings on your router work for most Wi-Fi clients, however, some older devices may not have access.
Solution: Contact your service provider for assistance. If you are entering the correct password and still unable to connect, change the network security setting to WPA/WPA2 Mixed Mode:
1. Access the Admin web UI and navigate to Wi-Fi > Primary Network. In the Security drop-down, select WPA/WPA2 Mixed Mode.
2. Click Save Changes and Confirm. Your router will reboot, and all devices should be able to connect.
If the solutions above do not resolve the issue, try the following:
Reason: Some Wi-Fi devices cannot properly store long passwords.
Solution: Change your Wi-Fi password.
1. Access the Admin web UI and navigate to Wi-Fi > Primary Network, or Wi-Fi > Guest Network, depending on the network to which you are trying to connect. Change the Wi-Fi password to between 11 and 16 characters.
2. Click Save Changes and Confirm. Your router will reboot, and all devices should be able to connect.
Reason: In rare cases, a Wi-Fi device may have issues with the same SSID being used on both 5GHz and 2.4 GHz bands.
Solution: Disable the 5 GHz band.
1. Access the Admin web UI and navigate to Wi-Fi > Settings. Uncheck 5 GHz and use only 2.4 GHz.
2. Click Save Changes. Your router will reboot, and your device should be able to connect.
