No Internet After Power Outage

Power went out twice today. After the second time the wifi stopped working. Ethernet worked but cuts out every 1-2 minutes. Time Warner/Spectrum wasn't much help and a technician can't come out until sometime next week so I started my own investigation.

The WiFi buttons on the router/modem no longer work and the NetGear genie app also says the wifi is turned off. I went and got a new router and this one won't even connect via Ethernet but the wifi works at least now. So far I've tried:

-unplug router, wait, plug back in
-command prompt + netsh and ipconfig resets found via google
-uninstalled and reinstalled network driver
-tried connecting a laptop via Ethernet (laptop wasn't plugged in during power outage so I'm sure it's not the network adapter)
-ran windows troubleshooter (says it's set up properly but there's an issue with the DNS server not responding)
-changed DNS from auto to Google and open DNS options but still didn't work

ISP says they see the device is connected and working on their end but it's not the case because they said the same of my old router when it started acting up. Not sure of this helps but when the old router was hooked up and the internet would go out I was getting an error message about DNS_PROBE_FINISHED_NO_INTERNET. I'm fairly certain something is wrong on the ISP's side but can't tell for sure and they of course won't admit it. I needed a new router/modem anyways as the wifi on the NetGear stopped working after the back to back power outage.

Any help would be appreciated.

Old Router: NetGear c6300
New Router: Zoom 5363
 
I have cable for the internet provider. I tried everything again this morning after having everything unplugged for the entire night, but still no difference. The LAN works for things like streaming video to the TVs or remote playing steam games to The an idea Shield TV, but no internet access at all. Internet light just keeps blinking.
 
Lets say your old modem/router is actually defective. You can not just replace a device that has a cable modem. In most cases you must give the ISP the mac address of the device you want to connect to the network. This is how they make sure they get paid. They should be able to do this over the phone without coming out to your place.

Most cable devices have a screen that will show you the signal levels and things like error counts on the connection going to the ISP. You can generally tell if the device is in communication with the ISP or not. This would tell you if the problem is cabling or software stuff.
 


I've already called them and gave them the new CMAC yesterday which is how they seen that the router is up and to them functioning and receiving data when in fact it isn't. The also try to do a "reset" on their end which is supposed to reset the router but nothing happens but they say they see it shut down and reset.
