    That means the modem isn't provisioned. I bet the gateway is still activated. Send a email to cox.help@cox.com with your account info and a link to this post asking them to provision your SB6190 for data. This is similar to this thread where the user had 2 devices on their account.

    Maybe they need to do a "full reprovision" where I think they take the modem off the account then add it back on. Either way, if you are getting a 172.x.x.x IP you are locked in the self registration system walled garden. This gives you a connection to Cox's network, but not the internet in general. That's why all the lights look normal on the modem and router.

Can you post the modem's signal levels from 192.168.100.1? I want to see if the DOCSIS network modifier is enabled. See here for more info.  Do you get a WAN IP to your router? Last, what model router do you have?

First off, thank you for the response.

Secondly, here are the signal levels. https://imgur.com/a/DyC4fyV

The model router I have is a TP-Link AX1800 (edited)

I forgot to check the WAN IP, so I'll do that and check back in a moment.

    Interesting. Looks like your modem is online and passing all checks. What model router do you have? SB6190 is your stand alone modem. I assume you are using something for multiple computers and Wi-Fi? My guess is this is some kind of provisioning issue.

      Oh, I don't know why I read that as modem! My router is a TP-Link AX1800. Sorry about that!

        Probably saw model as modem. I say model because some people just give the manufacture.

        Luckily TP-Link has a very good support site. First, log in by going to 192.168.0.1 in a browser. Then click on Advanced > Status > Internet which should look something like this. Are you seeing a IP there? What is the first number of that IP? 172.x.x.x?
