Wifi networks drop too often

"I recently purchased my first Netgear Router "Nighthawk x6 r8000".  I got it all setup and followed all the instructions to setting it up.  My router did updated to the latest firmware available for it "V1.0.3.4_1.1.2".  Out of the box, it ran very smoothly (both ethernet and wireless" but over the course of a few days, ethernet started to slow down and my WI-FI devices keep dropping off every 2 to 3 hours randomly to all of my devices. If I power cycle (reboot the router) I get my speeds back from the ethernet connection.  Also, the WI-FI device will eventually come back and start dropping again.  I have 2.4GHz, and (2) 5GHz running for this router.  Each device has only been connected to it's connection (wireless) so it only knows the password for that WI-FI connection."

Router: Netgear Nighthawk x6 r8000

Firmware: V1.0.3.4_1.1.2

• 2.4GHz and both 5GHz are effected.
• All devices connect to wireless will lose connection. **5GHz will lose connection more than 2.4GHz.

Note:  I spent quite a bit of money like others to have this "amazing device" I've heard of and this is my first Netgear router.  Coming from an ASUS RT-AC68U; I quite disappointed in my first experience so far.  My "first impression" has not been great and hope we can resolve this matter soon.  Why did I moved from ASUS to Netgear... I thought I'd try a new company and see how their routers are.  I do hope that we can resolve these connectivity issues and forget the router exists and let it do it's job.
