I need help and I can’t find a phone number to contact anyone.  I’m trying to sign into my router.  I’m reading everywhere online that I should be able to type my router’s default gateway number into the search bar and hit enter but it keeps saying webpage not available.  Any suggestions?  Thank you. 

 

I have the Arris/Surfboard Router SB8200

Default Gateway number is 192.168.4.1

The SB8200 is not a router; it is a standalone cable modem with no built‑in Wi‑Fi capabilities. The easiest way to access its interface page is by connecting a computer directly to the modem, ensuring that only the computer is connected. Once connected, you can access the modem’s interface using the default IP address: 192.168.100.1
