If anyone could point me in the right direction I'd be most grateful...

My internet is a shared connection in the block of apartments I live in. The router is in the ground floor apartment and is WPA protected. I have the username and password so I can connect but don't have the login details for the router (and they have been changed as I've tried 'admin')

The thing I would like to do is this:

Sometimes if I'm playing the PS3 on-line or downloading or whatever the connection is painfully slow. Having run an IP scanner I can see there's someone else in one of the apartments also on-line. Is there anyway, using some software, that I could temporarily knock them off?
 

I don't want to shut them off permanently, just maybe turn them off when I need the connection! Obviously I don't want anyone else to know it's me either! 

Any tips, ideas or advice would be much appreciated.

Thanks

Wow.. never heard of 'letmegooglethatforyou.com' before... that's sweet! Haha.. I'll be using it Thanks RR!

Wish I could take credit for that, was only introduced to it the other day on the remote-exploit forums.

Makes me smile everytime
