Here's a guide on how to protect your router from cyber attacks.

Here's how you can tweak the DoS parameters of your router.

If you're not sure what value to set for a particular parameter better leave it by default.

Pay attention to the second document (tweaking the DoS parameter) section 4 and 5 (especially the text in red color).

It's explained how to find the sweat spot of your particular setup and setting the level to Low, Medium or High, so no local host been added into the Blocked Dos Host List when they don’t have any harmful internet behavior.
