Unable to connect to Cox High Speed Internet Network
I had Cox High Speed Internet installed Thursday, April 12.
The installation went quickly and painlessly and in less than an hour I had internet access. I bought a ZOOM 5350 Cable Modem/Wireless Router which worked great right out of the box. Since last evening, Friday, April 13, I have been unable to access the Cox High Speed Internet network. I called tech support and went through the usual diagnostics (PC network configuration, wired/wireless connections, etc.) Tech Support can see the Cable Modem on the network and can remotely reboot the Cable Modem on the network. I can communicate with the Cable Modem (wired and wirelessly) without any difficulty through the PC, but am unable to pass or receive any data through the Cable Modem.
The only thing I have been able to determine is that the Cable Modem's Dynamic IP Address is no longer dynamic. After approximately 20+ reboots and resets since the loss of the internet, the Cable Modem's IP Address is the same every time. When I reboot the Cable Modem without a cable connection, the IP Address is blank, so the old address is not being retained in the Cable Modem.
Since the Dynamic IP Addresses are being furnished by the Cox network routers, it seems to me that this is a network problem.
I restored my (substandard) AT&T DSL connection so I have internet access, but want to get my Cox internet problems straightened out so I can finish firing AT&T.
Any ideas?

IP addresses are allocated dynamically so if the router portion of the modem isn't obtaining an address that would indicate a problem with the device or it's settings. You would try exchanging the device if you are still within the retailer's exchange policy windor or contact Zoom for assistance with the router portion.

Does not matter if you have a static IP or not, you will ALWAYS get an IP from Cox when you set your device to use DHCP.
Sounds like you router/computer is having an issue. Since you are a new install you should be able to get a service call for free. The installer should have given you their number, try calling them and explaining the issue to them.
