Nighthawk MR60 mesh not working

when you say "My regular modem was working and everything" makes me think its not just a modem but a modem/router combo device. 

What actual modem do you have? 
if its a modem/router combo device, it causes a double nat. 

A double nat happens when you cascade more than 1 router.

Fixes? There’s 3 options but only use 1.
1. Put the modem/gateway in modem only/pass through mode. This disables its routing functions.
2. Leave the modem/gateway in router mode but put the Netgears IP address into its DMZ. This forwards the data to the netgear. You can either leave the modem/gateway’s wireless enabled or disabled. Just make sure its using a different wifi channel to prevent interference
3. Put the Netgear into access point mode. This disables its routing functions. Wifi/ethernet still works but it does disable some features.

I would update the MS the the MR to v.132 version of FW:

Hello I have MR60 mesh set up and everything was working no problems. I turned off the power to the house as we were doing electrical work. Once we finished and power was back on I couldn’t get the mesh set up to work and it was not getting any internet while my regular router modem was working perfectly. Could the power outage damage the mesh set up! I have tried to reset, unplug and yet no luck?? Any suggestions? Thanks in advance
