What firmware version do you have on the device?
A number is more useful than "the latest". (It may not be by the time people read this.) There can also be newer versions, or "hot fixes", that do not show up if you check for new firmware in the browser interface.
It might also help if you told people what the modem is in front of this router, if there is one. The model number could be useful. Is it, by any chance, also a router, with a set of LAN ports on the back?
The reason for asking is that a lot of people turn up here trying to put a router behind a modem that is also a router. That can complicate troubleshooting.
Netgear's firmware is great at creating false reports of DoS attacks. Many of them are no such thing.
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.
While many questions about routers are generic and could be answered anywhere, some things need specialist knowledge.
You might get more help, and find earlier questions and answers specific to your device, in the appropriate section for your hardware. That's probably here:
The DoS entries are quite normal for Netgear routers, it's unlikely they're specifically causing the problem. How often is the internet disconnecting? Does it reconnect on its own, if so how long does that take? If not do you need to do a reboot or reset to restore it?

Does this mean that writing those entries is unlikely to overload this router's processor?
Disabling the recording of those entries, along with turning off QoS and traffic metering, has been one suggestion for dealing with troublesome routers.
What Firmware version is currently loaded? What is the Mfr and model# of the Internet Service Providers modem/ONT the NG router is connected too? Be sure your using a good quality LAN cable between the modem and router. CAT6 is recommended.

@michaelkenward Very unlikely, the router would be dealing with those connections anyway so writing it to the log would be minimal additional processing. Unless it's literally flooding the log constantly all the time then there wouldn't in my opinion be any need to turn off those entries.
