Re: Who is using my bandwidth?
You may be able to monitor his IP address from the router. Some router will also provide SNMP capability so you can easily graph his IP usage using tools like MRTG. This does get a bit complex, and may not be what you need to do at this point.
Easy way to see if its him, when things are running very slow, change wifi password or turn off wifi and test on your end.
