26.4 Resetting the Router to Its Factory Defaults
If you reset the Router, you lose all of the changes you have made. The Router 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 Router,
1 Make sure the power LED is on.
2 Press the RESET button for longer than 1 second to restart/reboot the Router.
3 Press the RESET button for longer than five seconds to set the Router back to its factory-default
configurations.
If the Router restarts automatically, wait for the Router to finish restarting, and log in to the Web
Configurator. The password is “1234”.
If the Router does not restart automatically, disconnect and reconnect the Router’s power. Then,
follow the directions above again.

3 Make sure the wireless adapter installed on your computer is IEEE 802.11 compatible and supports
the same wireless standard as the Router.
4 Make sure your computer (with a wireless adapter installed) is within the transmission range of the
Router.
5 Check that both the Router and your wireless station are using the same wireless and wireless
security settings.
