Cox Not Allowing 3rd Modem to Connect?
I recently just started with Cox and for some reason my modem has not been able to connect to their service. At first I was using a Netgear CM700 that would signal having the upstream and downstream just fine but would be denied connection to the internet. A tech came out and we figured maybe something went wrong with my modem since the Cox Panoramic Gateway worked just fine. He recommended getting an Arris, so I did. I got the Arris SB6190, fresh from the box and the same exact issue occurred again. I have talked with support and they said everything is activated and it should be working, yet when I go onto my account it still lists the Panoramic Gateway as my modem device and I cannot add another modem to my account.
There is another tech coming to try to figure it out, but largely I am wondering if anyone else has had this problem with Cox or is this some new scummy practice by them to force people into renting their modems? Does anyone have any advice in getting the modem to work? I've tried power cycle, switching coax cables, etc. Nothing has worked as again all I get are two solid blue lights for the upstream and downstream and a solid white light for the internet.
That means the modem isn't provisioned. I bet the gateway is still activated. Send a email to firstname.lastname@example.org 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.
