Nighthawk R7000 with CM500 Modem on ComCast - internet light always off
Hello,
Problem:
Router R7000 with firmware 1.0.4.30 is connected to Netgear modem CM500 which is connected to ComCast Cable internet.
Everything worked fine until yesterday - nothing changed in setup, the internet stops working.
Called ComCast - they confirmed they were able to ping the CM500 modem. I connected ethernet cable from modem to laptop - internet works fine. ComCast confirms modem & internet is fine - problem is in the R7000 router.
When i connect ethernet cable from modem to laptop, the ethernet light in the modem is green/stable. When i connect the same cable to router, the ethernet light in the modem doesn't light up. Also on the router, the internet light doesn't light up at all.
Troubleshooting performed on the R7000 router:
Restore to factory settings
Power Cycle the router/modem set up
Firmware upgrade & repeat the above
Installed NetGear genie app and repeated all the above tests
I do see the MAC address on the router. Did refresh of laptop internet settings etc.
Contact with NetGear Support:
Contacted them to see if they honor the 1 year hardware warranty (since my router is still within this period). They asked me to post in this forum and didn't confirm anything about the 1 year hardware warranty - this sounds very weird to me, as clearly something is wrong with the router & I did not cause it to go wrong. Purchased the router from BestBuy and I have the purchase receipt.
Can someone help me with how to proceed from here? I am pretty confident that I need to change the router - but I don't want to just buy one myself since the router is 9 months old & within the hardware warranty period. Please advice. Thanks,

Why they sent you here I can't understand? I would have called back to talk to a different person or asked to speak to a supervisor.
One question or I guess questions? You've got a laptop, right? It has a cable that you used to connect to both the modem and the router, correct? It works fine to the modem but not to the router, correct? Do you have a DIFFERENT cable that connects to the modem to the router? If so, it is possible THAT cable went bad? Do you have another to try? If not, use the laptop one between the modem and router. Do the lights work properly then? If so, the cable is bad.
I also assume you've used the proper bring up method for the modem and router when changing connections. In all cases you must power OFF all items, modem, router, and PC (or any devices connected to the router). Then one by one, power them up and wait for them to fully initialize before turning on the next device, modem first, then the router and then the PC. Those devices store the MAC address of the item they expect to connect too. If not found they don't connect, so you can't 'hot swap' cables around and expect them to work.
