Cox doesn't rent modems, only modem/router gateways. If you want a modem, you will have to buy it. I think Cox sells the CVA4004 in the store, but I don't know for how much. See here for a full list of compatible devices. The ones marked "integrated wifi = No" are regular modems. The Arris S34 is a great modem, or the Hitron CODA if you trying to save money and get 1Gbps or under service.
Do you pay for the combo/gateway? If so, you can put it in bridge mode and use your own router. You would need a router with a ethernet WAN port and be DHCP compatible. If you have 2Gbps service, make sure the router has dual 2.5Gbps ports, one for WAN and one for LAN. The Cox site has a list of tested routers if that gives you someplace to start.
If user: admin password:password don't work, someone must have changed it. Factory reset it. If it's a white Panoramic gateway, press the WPS button on the back(above phone jacks) for 60 seconds. It needs to be the FULL 60 seconds, otherwise it just activate WPS, which is for adding wifi printers and the like.
PS. Don't use chat. Either call Cox during normal business hours or use one of the methods in the sticky on this forum.
PPS. Are you internet only? No phone? I ask because if you have a phone, you cam swap the Panoramic gateway for a FREE internet/phone(eMTA) like the TM3402. No router inside so you can use it with your own router.
