Router Can't Detect Modem in WAN
Modem to WAN (Router) Connection
So I've been connected to the internet fine for years, but just recently my router disconnected and I can't seem to get back online without directly connecting to the modem with cable.
When I checked on my router during the disconnection the lights where all on like normal, as if nothing happened. So I reset my router and usually the internet just comes back on, but this time around the lights came on normal, but no internet. I checked to see if it was the modem or Cox, afterwards.
When I connected the modem to my computer it connected saying unidentified network and then kept retrying. So I turned of my modem and unplugged it, letting it sit for about 2 minutes. I plugged it back in and retried, after awhile of it coming back unidentified and attempting multiple reconnects, it finally went through. One thing to note is upon boot up of the modem, the lights DS and Link flashed orange for a bit, but quickly went back to green if that has any significance. Afterwards I figured, since I can connect to the modem, maybe my router would work.
Nothing. So I turned and unplugged everything (my computer, router, modem) and waited 5 minutes. I then proceeded to turn on modem, wait till it fully loaded, turn on router and wait for it to fully load, and then turn on my computer. Nothing.
So I tried with a different router, did all the above and still nothing.
So I tried resetting both routers and repeating above, nothing.
So I tried to find out the problem and my router let's me setup the internet connection through a setup wizard so I tried that but it says it can't detect any connection in the WAN from a modem. So I switched out to two different types of cable, nothing.
I'm not sure what to do...I'm worried that even if I bought a new router things wouldn't work since it failed on two routers it used to work with before.
Modem: Cisco DPC3010
Routers:Netgear WNR1000V2 & Airlink101 AR670W
I know most people will probably say it's my router, but I'm having trouble connecting directly to the modem without resetting it as well so I'm wondering if it's something in the modem. It's really frustrating because it was fine an hour ago.

You didn't mention if the original connection from your computer to the router was WiFi. Your equipment may be fine but there's a wireless conflict. That's a configuration issue. Did you recently add a device to your wireless network? Are you limiting the active devices on your network? After you're resetting the router(s), is your Network Key (encryption) correct? Is your computer connecting to the reset (default) wireless Network Name (SSID)? If you're resetting your router to its original factory settings, the wireless adapter on your computer will need to match the new, default settings. That is, if you're using wireless. No?
Is there a Reset button on the back of your modem? It will be a recessed button to prevent you from accidentally pressing it. You'll need a paper clip or some type of skinny punch to press it. Don't just press it...press and hold it for 1 minute.
- Power off computer and router
- Press and hold Reset button for 1 minute
- Allow modem to reconfigure itself
- Disconnect power to modem for 1 minute
- Reconnect power to modem
- Allow modem to boot
- Power up router and computer
FYI. After you switched the connection from your router to your computer, the flashing orange lights on your modem indicated your modem is updating its routing table. Your modem was configured (automatically) to communicate with the MAC and IP addresses of your router but when you change devices, it had to update its table. You connected three different devices. Your computer was waiting for your modem to reconfigure itself.
If that doesn't work, the cheapest option would be to replace the modem at a Cox Service Center. Ask for a new one and not a used one. Or, just toss all of YOUR equipment and swap your modem for an all-in-one modem-router at Cox. You may start paying a monthly rental charge for it.
However, your modem may be fine and your router has finally burned out. You said after previously resetting your router, "usually the internet just comes back on." This hints to a history of problems. Why do you have another router? What's its problem...why did you replace it? Maybe you're troubleshooting with a questionable router.
A wireless issue may indicate a recent change to your WiFi network. A wired issue may indicate a faulty router or faulty port.

SOunds like the modem is having a hard time handing out a valid IP. I would connect modem direct to PC, reboot modem, and see what IP your PC gets. If your getting correct lights but no IP or invalid IP (169,127,172.0.0.0,etc) its probably a issue in the area or configuration file issue, which usually means issue with your account. Probably best best for a moderator to check the modem from their side first.
If it detects "network cable unplugged" then its either the ethernet port on modem or ethernet cord.

Have a cox tech check your signals with the modem directly connected to your computer, that will answer a lot of questions.
