Lately I have been getting disconnected from my router. This occurs after every DHCP lease event, which also shows several DOS attacks. But again, this only happens during the DHCP lease event. A thought occured to me that maybe I have too many devices? I can tell you that I am extremely tired of factory resetting this router. Below is a log from this morning when it happened.
Im a fairly tech savvy guy, but I do not know routers yet. Any help would be great, I would rather not have to buy another expensive router.

Seeing how every DHCP lease event causes the router to crash and reboot, I dont think setting static IPs is going to fix that. For some reason, everytime the Lease renews, I suddenly get a ton of DOS attacks and a router shutdown and reboot
Wait so the entire router reboots itself when this happens? If that's the case try plugging the power directly into a wall outlet, if it continues try another power adapter. If it's still a problem then I would recommend getting the router replaced.
Short of wiring the power supply to the wall, that also has been done. I assue you that if i buy another router, it will never be a Netgear router. This is unacceptable.
I will say that finally, after 17 factory resets, I dont seem to have any issues. But I also dont want to use the QOS or any other feature because it will crash again.
It's highly unlikely to be any of the DumaOS features causing this so it may happen regardless. If it occurs again I would suggest either waiting for the 3.0 update or perhaps trying a previous firmware (you'll lack the latest security updates) or exchanging the router.
