2. What can I do if I forgot my password?
If you forgot your password, you must reset your router. This process will change all your settings back to the factory defaults.
To reset the router, locate the reset button (hole) on the rear panel of the unit. With the router powered on, use a paperclip
to hold the button down for 10 seconds. Release the button and the router will go through its reboot process. Wait about 30
seconds to access the router. The default IP address is 192.168.0.1. When logging in, leave the password box empty.
