I looked at the logs and I do see some suspicious log entries that I don't recall seeing before, for example:

Netgear's firmware is great at creating false reports of DoS attacks. Many of them are no such thing.
Search - NETGEAR Communities – DoS attacks
Use Whois.net to see who is behind some of them and you may find that they are from places like Facebook, Google, even your ISP. Yours seem to be from Amazon.
Here is a useful tool for that task:

If these events are slowing down your router, or maybe even causing the crashes you see, that may be because it is using up processor time as it writes the events to your logs. Anything that uses processor power – event logging, QoS management, traffic metering, n ot to mention Armor and Circle – may cause slowdowns. Disable logging of DoS attacks and see if that reduces the problem. This does not prevent the router from protecting you from the outside world.
