[Answer]: This has been happening from the day I bought R7400 AC2600 router. Got replacement under warrenty. It worked normally for sometime. However recently I upgraded the firmware and the issue of disconnecting abruptly started again. I downgraded to previous firmware, however the issue persisted. I have reset the router now, lets see how long it will survive without disconnecting.
What modem/gateway is it connected to?
[Answer]: It is connected to Motorola Surfboard SB6121 modem.
Is everything disconnecting? only a few devices at a time?
[Answer]: All devices fail to connect to internet.
What actual error do you get? "connected, no internet", the wifi not connecting to the router? What actually happens?
[Answer]: All devices fail to connect to internet, however Wifi shows connected on all devices. Even NIghthawk app's internet speed test fails.

try hardwiring a pc/laptop directly to the modem and use it for a long enough period to be certain it isn't the modem. When a device has been replaced and continues to have the same problem, I usually start looking at other things like the modem/isp's line.
Update: Today again at 2:48 PM PDT, Netgear router R7400 got disconnected. I simply disconnected router cable and connected to my laptop. It worked without restarting modem or laptop.
@plemans [Update]: After connecting the cable from Model to laptop without restarting model or laptop. I am still connected without any issues. So definitely, it is router issue. I was wondering if you can suggest any solution.
[Update]: Yes, I downgraded from firmware R7400_V1.2.0.88_1.0.1 to R7400-V1.2.0.76_1.0.1. However it still keeps disconnecting. It got disconnected twice from morning and its just mid day.
I have tried for around 6 hours. However is there any way to find router and modem logs. This will help me to figure whether its router or modem which drops the connectivity first for this events.
