  • Use a proper WiFi protection protocol (WPA2), change your passphrase and use a non-guessable one, and maybe change the SSID of the network to something like "HONEYPOT" :-). Additionally, you can turn on MAC filtering if available. Not great protection, but it's on top of the rest, and it's free.

If you want to stop them using your wifi you should increase your security, not hack them. In your router's wifi section there is a built-in mac filtering system that you can enable. You need to add your devices' mac address to the list and pick a mode. There are two main filtering modes there:

  • Allow (whitelist): Allow mac addresses in the list, deny everyone
  • Deny (blacklist): Deny mac addresses in the list, allow everyone

    Note that MAC filtering is useless against most attackers: it's trivial to figure out what addresses are valid and set a wireless card to use one of the valid ones.
