Hi,

I had bought G36 modem 3 yrs back which I am trying to re-install now.  I have registered the modem with Xfinity and the Wifi router is working.  My phone and laptop is connected to the Wifi.  I would like to change the Wifi/modem password but unable to do this.  My SBC app is not connecting to the modem and hence unable to setup the app; also logged into the web interface using 192.168.0.1 but it’s not letting me login, saying “Invalid login credentials”.  Is there a way to reset the web interface login credentials so that I can connect through the web interface and change my modem password?

 

Appreciate your help please.

Thanks much,

Prantik

During the initial setup, you’ll be prompted to create a password for accessing the web interface. If you’ve set up the Surfboard Central app, it will generate the password automatically for you If you’ve been using the web interface to configure your Surfboard gateway and happen to forget the password, We would recommend performing a factory reset on the device. This will restore the gateway to its default settings, allowing you to set a new password for the web interface.
