What sort of encryption are you using WPA, WPA2, or something else? – Ramhound Jun 19 '13 at 14:10

in the router configuration, you should have a mac-filtering option. add the mac-address of the user you want to block in the "blocked" section.

edit: the user can change his/her mac adress and reconnect, so you're better off with a stronger protection of the network...

(and change the type of key you're using, since it's so easily found each time, WEP key ?)
