Providing Tenants with Internet

[Steve N]

I currently have Students residing on my property who are only here for the summer. I want to set up wireless internet for them, but was wondering about liability in terms of what they end up doing online. If I set up a wireless router and give all of them access to it, can I be held accountable if any of the tenants download illegal music or hack a government website or something? How do I protect myself from getting into trouble?
