In the last 60 days, my router/modem will not stay connected. I loose internet mutliple times a day. Thinking it was a Service Issue, I had Spectrum come out TWICE and all is fine on their end. They think there is something wrong with my router/modem device.  When I log in, it says my firmware is up to date but even still, there is no where that allows me to update it. I am not sure what to do or try. I have done multiple factory resets as well.  It's less than 3 yrs old and just randomly started happening.  I also downloaded the Nighthawk App and it says the firmware IS out of date but there is no way to update. I am lost. Can anyone suggest something else to try??

What channel configurations are currently set on the router?  
What channels are you using? 
Any Wifi Neighbors near by? If so, how many?

Please post a copy and paste of the modems connection status and event log page.

Ok, Power levels are too high:

Some correctables that should be zeros however there not too bad. 

Any Criticals, Errors or Warnings seen in the event logs needs to be reviewed and resolved by the ISP. Indicates a signal issue on the ISP line up to the modem.

Be sure your using a good quality LAN cable between the modem and router. CAT6 is recommended. 
What is the brand and model of the host wifi router connected to the modem?

Have the ISP check the signal and line quality UP to the modem. Be sure the ISP provisions the modem correctly.
Be sure there are no coax cable line splitters in the between the modem and ISP service box. 
Be sure your using good quality RG6 coax cable up to the modem. 
Start with removing any amplifiers, signal attenuators, or splitters from the coax.
From there check the line for kinks, damage, moisture in the line.
Check the connectors for improperly made ends, foil touching the copper coax line, loose connections, bad/old/cheap connectors, or corroded connections. Replace them if you do.
Be sure to power OFF the modem for 1 minute then back ON.

I appreciate you trying to help but I am so confused by all the jargon. My Netgear device is a AC1600 WiFi Cable Modem Router so it's all one device. I have nothing else connected. All technology is connected via the wifi.  The Modem/Router is plugged directly to the wall and nothing else.  

Spectrum (my internet service provider) has been here TWICE in the last three weeks to check the lines from the road to the house and the house to the modem/router and all check out. They say they can not do anything else for me because the issue is on the end of the Modem/Router. Each time they say that their lines are fine and numbers are fine and it's my device. 

I can call Spectrum again.

Have them look at the logs and the information I posted.

I just tried to show Spectrum what you wrote and was in a chat with them. They are saying it's my netgear product. They gave me the number for tech support to Netgear.  I just called Netgear and because I am out of warranty they will not help unless I purchase a new contract/warranty. At that price, I can just go buy a new device. I appreciate you trying to help.

Might ask the ISP if you can test one of there's to see if the problem solves or not. If the signal on the line is bad, any modem may experience problems. 

Good Luck.
