I have done a FULL factory reset and manually reentered all parameters. The unit will randomly reboot, sometimes 3 hours of runtime, sometimes 24 hours and everything in between. Here is a link to the log just prior to a reboot. I can't attach this file for some reason: https://app.box.com/s/5hbub0a6nw7btiznx1sgg85kb8946f63
All lights go out, full stop reboot.

Help!

Help!

seems just before each reboot you get a flood of dnsmasq errors "failed to send packet: operation not permitted" . So whether its dnsmasq itself or something internal causing dnsmasq to fail is not evident within the log. All you can do is do a factory reset - configure everything from scratch again - do not use a backup - and hope your problem is resolved. I noticed you tried that already- maybe do a WPS reset instead

I did a 30 30 30 reset as well as a WPS reset. I’ve been searching my Network which has a lot of devices and found one that had multiple IP’s assigned to it according to a network monitoring appliance called a Fingbox I have. I have deactivated/removed that device from my Network. I’ll see what that does. My Fingbox was also reporting another DHCP server on the network which has disappeared when I shut off this other device. By the way the device with multiple IP‘s was an Amazon fire stick. Is it possible that a network device could cause a router crash? The main thread seems to be getting a SIGTERM which starts the reboot.

Try the following to get your router/network back to a good/known state. Note that the 30-30-30 reset doesn't work on Asus routers (it never has).

Fully Reset Router and Network

See the M&M Config in the link above for further notes.

Yes, it has been reported a few times that a client device can be the cause of a router crashing/rebooting. I would power down the entire network and add devices a few at a time, testing as you go.

The above suggestions may also help get rid of any old incompatibilities too.

I reset it 3 times, 3 different ways. The one device that I thought was causing the problems has been off the network for 20 hours and there’s been no crash. Fingers crossed.
