Open for suggestions to blocking one person from LAN?

Question

Ok, here goes, person A who lives near me shut down her Wi-Fi after finding out person B has been accessing tasteless web pages. Now that someone else is back home, the Wi-Fi is back up for her laptop, but now the issue has risen again. So I know I could capture person B's MAC address and ban her from the wireless, but also I need to keep her from pulling the Eth cable, sticking it in her laptop, and using that old-fashioned "hard wired" internet.

Answer 1

The wireless part should be locked down, as others have mentioned, by hiding its SSID and enabling WPA security that requires users to know the passphrase in their wireless card settings. This should be done on all non-public wireless networks.



However, you suggest that the person you want to block has physical access to the router that would let her plug an ethernet cable directly into it from her computer. Wireless security will not help you in this case. For this you need to use your router software to get her "hard wired" ethernet adapter's unique MAC address. Then, only if your router supports this, you can block that MAC address from using the Internet. If your router does not have this ability you can get one for about $50 these days that does it. The new ones can even let you restrict a MAC address to certain sites, so you could let the person check her email or facebook but not go to any other sites.

Answer 2

Both the ethernet card and wireless card of a laptop have different mac addresses. Just block the mac address of both of them.

Answer 3

Password! Firewall!

Sounds like you are hacking her signal too.

Bad Neighbor.

Answer 4

turn your ssid off and activate your wpa2 security change the password and don't let her have it
