Why can’t I get an Internet connection?
For ADSL ISP users, please contact your ISP to make sure the service has been enabled/connected by your ISP and that your ISP username and password are correct.
What can I do if I forgot my web UI login password?
If you forgot your password, you must reset your router. Unfortunately 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 10-15 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
