Left Cox for Qwest How unfortunate your experiences with Cox. My very good friend works for Cox Technical Support. He is far from deficient in knowledge. I believe one primary reason for directly connecting to a modem is because if you have 169. ip address, you cannot release and renew the ip address with the router connected. As Cox is not the Manufacturer of the Router nor does Cox supply the network Key, network name, or decide which type of router configuration is used, novel users of the internet may become confused when they have a solid internet connection but lack of knowledge in dealing with their OS and router configuration. At least that is what I am told?
