Share my internet and files

I am moving into a house with tenants. We have to share our internet connection with them. I am also building a home network for sharing files, printers and streaming content. I do not want them to see my files or contents. Is there any way I can share the internet connection with them but my files stays with my computers. I have a desktop which will will be the main server with windows 7 and 2 laptops also Windows 7. I am not sure about there computers. The ISP gives only a modem if that helps.

You will need a router to share the internet connection from the modem. Preferably a wireless router. Depending on the router you get you have a couple different options.

A. You can set up a guest network on the router that would allow the other tenants to connect to without seeing any of your devices on your private main network. This would be preferred if I were in your shoes. It would give them their own SSID and password.

B. You can set up a homegroup with windows 7 or manually pick and choose the files you want to share and choose the PCs you want to be able to connect to these files.

Most new routers have this feature. I would start by finding a high quality router and then researching or downloading the manual to make sure it has the guest network feature. There are lots of good choices. Depends on how much your looking to spends of course too.

Heres a good place to start - http://www.smallnetbuilder.com/lan [...] 2_4-ghz-dn
