if you are using a wireless router, lock in wep or enter your mac address into the router and make sure you lock the router access, by changing the password.

static IP, mac filter, wep/wpa encryption, limit the number of users.

You should be able to see what his IP is logging into your router. You can Mac filter just that mac address.
