R7450 keeps dropping internet connection
I have the Nighthawk R7450 router (firmware v1.2.0.76_1.0.1) for about 6 months now, this problem has been going on since i got the router, and i am totally confused on it. Prior to installing this ...

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:
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.

Thank you very much for the reply - i went in this morning and changed the logging on the Nighthawk - looks like the default was log everything because all the boxes were checked - so i reduced that to ONLY log for:
- Connections to the Web-baswed interface of this router
- Router Operations
- Port Forwarding / Port Triggering
- Wireless Access
- Turn off wireless signal by schedule
Changed the logging to this at about 8am EST, at 845a my VPN bounced again and the logs show this:

But do not know why this is happening. So the logging is reduced, but problem still happening

just an update on this issue - my Anyconnect VPN has been stable since the 0845 reset - so maybe I am on the right path.
Also found this very helpful document someone posted on another site for Users with AnyConnect working from home getting the disconnects: https://www.bleepingcomputer.com/forums/t/696040/windows-10-wireless-and-vpn-disconnect-reconnect-issue-procedure/
I went through the Step 1 on that link - so lets see how it goes.
thank you,

Update 245p today - AnyConnect just restarted the VPN on its own :(. also less frequency so far, it is still happening.
computer did not go to sleep, was in the middle of a webex, when this happens i loose all connectivity for 30-60 seconds but webex recovers on its own - just video and audio go blank.
So frustrating really - never had this problem before with old Airport express, maybe because it didnt know better - who knows.
Anyone seen this and has suggestions pls let me know - thx
