22.5 Reset the WiMAX Modem to Its Factory Defaults

If you reset the WiMAX Modem, you lose all of the changes you have made. The

WiMAX Modem re-loads its default settings, and the password resets to 1234. You

have to make all of your changes again.

You will lose all of your changes when you push the Reset button.

To reset the WiMAX Modem,

1Make sure the Power LED is on and not blinking.

2Press and hold the Reset button for five to ten seconds. Release the Reset button

when the Power LED begins to blink. The default settings have been restored.

If the WiMAX Modem restarts automatically, wait for the WiMAX Modem to finish

restarting, and log in to the web configurator. The password is “1234”.

If the WiMAX Modem does not restart automatically, disconnect and reconnect the

WiMAX Modem’s power. Then, follow the directions above again.
