Problem: DoS attacks & pings of death
hunreds a day on my logs, internet goes out repeatedly through out the day across all systems on my network.
Netgear's firmware is great at creating false reports of DoS attacks. Many of them are no such thing.
Search - NETGEAR Communities – DoS attacks
(You may find recent conversations from people with cable modems.)
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:
IPNetInfo: Retrieve IP Address Information from WHOIS servers
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.

Firmware version is current according to Netgear site and what my admin site is showing. Currently with a level 3 technician at Comcast as well.
There is nothing you can do about firmware on cakle modems. It is in the hands of your ISP. Most hate rolling out firmware for their own devices, let alone users' kit.
If your firmware is outdated, you cannot manually upgrade your cable modem’s or modem router’s firmware. You must contact your Internet service provider (ISP) to upgrade your firmware.
