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.
Here is a useful tool for that task:

If these events are slowing down your router, 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 – 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.
