Unable to create log in for Web Manager for SBG7400AC2

I got my modem/router refurbished so I am not sure if there was already an account created for it, but when I try to go into the Web Manger and put in the dummy username and password of admin and password, it says my password is incorrect or I have been locked out of my account for too many incorrect attempts. I have never had an account before- this device is new to me. 

I don’t have a warranty due to it being used, so when I called support, they would not help, just said to try to rest the modem, which did nothing. I am having major connectivity issues and want to trouble shoot, but cannot even get into the online account to change my password let along run a signal strength test. My wifi company says the issues are with the Modem. Anyone have any idea how to reset the password so I can make an account? Thank you!

We recommend accessing the web interface using a different browser and clearing your cookies and cache, as this often resolves login issues.

And during the initial setup, you’ll be prompted to create a password for accessing the web interface. 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 without the coaxial cable connected. This will restore the gateway to its default settings, allowing you to set a new password for the web interface.
