Help securing my connection

I have DSL with a Actiontec GT701-WG DSL Modem hooked to a Linksys 5 port switch. My wife has reciently set up a home office and shares one of the ports.

My question is, I believe her company has accessed my modem. I think they changed setting as I had to restart my computer to get a connection after they were messing with her system. They spy on her desktop but I don't want them to be able to see my computer or my web-log. If I change the password to my modem, does that limit what they can do to her computer? What can I do so they have access to her computer but not to mine?

Code:

                  ___[Wife]
                /
[Modem]___[5-portSwitch]   
                \___[New Router/Firewall]___[You]

Brand or model of router/firewall to use? I have a Linksys Cable/DSL Router with 8 port switch. Would that work? Would they be able to see data coming across the modem? Or web-logs? I visit many different sites that include political and blog sites. I've checked the web-log and sometimes it contains sites I've never been to. I assume they must somehow be linked to the political site visited.

You can use any Wireless Router to create segregated Network for yourself 9as suggested above by SpywareDr

It is impossible to make any comment about the Alleged Spying oon your wife's computer (or Router) without knowing what technically was done.

"They" who? Your ISP can keep track of all traffic in/out of your connection.
