Did you agree in the lease to "share your internet connection"?
Is this a separate unit or a roomer in your home? Do they also share your
telephone line?
If it is part of the rental agreement then you will need to limit his access
to your network AND protect your computers.

If it is not part of your rental agreement and your tenant has their own
unit................let them get their own internet connection. Cut them off
quick before it becomes "ASSuMEd" that it is part of the lease!

I would not want anything negative coming from or to my network! Don't some
"nice college kids" create viruses, download porn and download tons of
music/videos?

I remember one college kid, who was taking a computer course, was instructed
to do an assignment on security, or lack of it, and the computer. The
professor was about to give him an incomplete on that assignment since he
could not find it in the paper pile. Then the student pulled up his
assignment on the professor's computer. Professor was NOT happy that he was
able to upload it onto HIS computer but the parents reminded the professor
that it WAS the assignment.
Well I thought it was funny! lol

So if you TRUST him, and I wouldn't, then it is up to you!
I would change your wireless settings!

JMHO
