Kali Linux. Router security?

Question

Computer networks

Good afternoon.
Testing Kali features on my router.
I'm testing the possibility of implementing deauthentication using aireplay-ng -0 0 -a MAC TD -c MAC Client wlan0mon and mdk3 wlan0mon d --b file.txt
It turns out that I fall off the network, everything works. And there were questions.
1. How can I protect myself from deauthentication? (router settings, something else) If suddenly I was "attacked".
2. How can they help me in those support? Will they make some tricky settings on the router?
3. The computer works through a WiFi card. If I start connecting the computer via a wire, then these "commands" will not be able to deauthenticate me, can they? Or are there utilities in the Kali set that can also jam the computer over the wire?
Thank you.
