Geez, so I'm on a Mac, how do I stop people getting in using the Admin password?
Unless you've changed it, your wireless router will be setup with a default password - there are two passwords, one used for accessing the wireless network and encypting the transmitted data, another for being able to log into the router itself.
Since you have a wireless password setup, as fas as I know, they can't get onto the network to even have a chance to use the default password, unless they got into your house and physically plugged in, or went through the big job of trying to hack the password! It's no biggie to change this default password, search the manual or the menus in the router and you'll find it.
I also like to enable hiding the SSID broadcast, so to someone standing outside or even in your home, they can't even see any network available, without you telling them what your SSID and password is.
Another security measure is to enable mac address filtering, which is basically the unique id of every networkable device, such as phones, pc's, game consoles, etc. Setting these up is a little more fiddly, but it's all explained in the router manual. Even if someone knows your SSID and password, they still can't get on if you haven't put thier mac addess on the list in the router.
As you've said, I too think that it was all vuze's fault, but just think of the pirates that are happy all because of you
