Well first of all, i just would like to say this is a question im asking not really a problem. I didnt really know where to place the thread, so if the staff think this is a inappropriate place for this question feel free to move it where it is related.

So my question is, i use a wireless network connection to connect to the internet via a router. The wireless connection is protected by a security method called WPA. I was just wondering, is there any possible way that someone else can be using my network too by hacking into it? how can i tell, if they are? and how would i resolve this dillema?

My operating system is, Windows XP Professional, SP2, with 1gb RAM, AMD Processor.

Thank you for your time

Anyone?

well, by "hacking into your network" do you mean "using" your internet, or do you mean changing settings and stuff.

The answer is that there is always a way but its unlikely. I would recommend downloading one of those programs that will reveal all ip's on your network, that way you can tell if there is one extra or not.

yes i meant by using my network to gain access to the internet.........

By logging into your router you should have logs you can read
to see if extra IP's are using the router. Using WPA-PSK means
you have a pretty secure connection and it will take some effort
to gain access.
Google your router manufacturer and check out their site for info
on how to access the router and check the logs.
Also take a look at 'MAC filtering', this will give you another level of protection.

thank you

I'll mention one more thing too... Be sure your User Name/Password to the Router is strong(difficult to figure out for a "hacker"). That is the easiest way to compromise a home network connection. I'm sure you've got that handled already though.
