understand it your computer is protected by what ever security system you are using on the computer.
the router would be protected by making it secure with wep wap security.
Just my thoughts
I am new to wireless networking. I have had a wired router for several years and am making the switch to wireless for my laptop. I have an older desktop and a Playstation 3 that is wired in as well. My silly question is this: If I use my wireless router for my DSL connection and continue to use the wired connection for my desktop and Playstation 3 will I still be leaving my files on my desktop unsecured when my son is online with his Playstation? The wireless router is for my laptop only. I do not share files with the two computers.
