Nighthawk X6 R7900 Restarting Frequently

Model: R7900|Nighthawk X6 AC3000 Tri-Band WiFi Router Hi, hoping to get some ideas on my router. This has been a bit of a process with the troubleshooting I've gone through, but I'll try to lay it out. I recently moved and switched my ISP, and tried switching my router to AP mode since the new modem has its own router. I noticed while I was working on this that the router seemed to be restarting somewhat frequently, maybe once every few minutes. This might have more to do with me attempting to connect and use devices with about that frequency, because (looking at it now) it doesn't restart that often.... but there's a good chance it will restart the moment I try to use a device connected to it wirelessly with anything remotely intensive. Anyway, steps I've taken: -reverted to factory default settings -upgraded to latest firmware -reverted to factory default settings again -changed the cable between the modem and the router -attempted to "30-30-30" reset it (to try and downgrade firmware), but that didn't seem to do anything... so instead I downloaded an earlier release of firmware and loaded it manually. -re-upgraded firmware (after much struggle... the prior firmware version seemed to like to make the router restart every 30 seconds, so I had to get into settings real quick to manually upload firmware, often non-responsive, thought it was bricked...) -reverted to factory default settings again -disabled “Wireless Router Radio 2" (attempting to reduce power, if that makes sense) -lowered 5ghz-1 to the "up to 600 mbps mode" (attempting to reduce power, if that makes sense) -switched the radio 2 and re-upped the mbps modes to max, so now I'm basically back at ground 0 It’s plugged into the ethernet port of a ZyXEL C1100Z from CenturyLink. Like said before, it's been.... decent today, restarted on me once in the morning and again just a few minutes ago. It seems that use triggers it, and it seems to happen more often right when a device connects to it (like when I turn my laptop on). If it doesn’t happen right away, after a device connects, it might act well for a while before it finally turns off.

I had the same problem. Try replacing the power supply for the router. That worked for me. One would think you could get support from NetGear but they are about zero responsive to support their customers.

I hope to find a better more reliable router from another company. Also NetGear equipment (specifically a switch) does not work with my astound cable modem.
