Nighthawk R7800 router

[Lucapee]

It happens
that the router with latest FW (1.0.3.92) reboot itself, sometimes in the log appears a line as DOS ACK (denial of service), but not always, it could be a bad FW setup? although the router is out of support it could be possibile to have a FW updated? or someone had solved this in other way?

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.

No need for a firmware update. See above.

Just another user with time on their hands.

I'd install Voxel's firmware if I was you. It's actively maintained and runs smooth, with updates components compared to the stock one.

I agree with @microchip8.
