I once got this and it was resolved by rebooting the cable modem. If you have COX they won't directly help you fix the problem because they don't support routers. Also you did not perchance change where the ethernet cables are plugged in did you? There is one place that is marked as WAN and it should have the cable modem connected to that port.
If you need help send an e-mail directly to me at [email protected] I probably won't be back on until 8:30 AM Eastern US time.
