1 router but two different networks

[anon2012]

I work in a small office and use a laptop with Windows 7. We use the same router and have wired internet. His computer is connected to a "Network 4" while mine is connected to the private wireless internet system we've set up. He can't connect to any other connections on his computer while all the other connections around our office is visible on my laptop. What can I do to get my boss on my network so we can share files? Thank you!
