• Check the settings for QoS. If it is disabled, you might consider activating it. If it is enabled, you 

might consider raising or lowering the priority for some applications.

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,

Make sure the power LED is on.

Press the RESET button for longer than 1 second to restart/reboot the Router.

Press the RESET button for longer than five seconds to set the Router back to its factory-default

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.
