Conflict with another computer on the network....

[White97TA]

I keep getting this error, disconnects me from whatever I am doing at the moment. I have this problem alot now. I have 2 computers set up in my house, one wired directly to the router, and the other wireless.

Tonight this happened at least 10 times within 3 hours. It's really making me angry now.

I guess the question is, how do I really secure the wireless network so others cant access it? Only thing I can think of is someone around me is trying to use the wireless access to get on the net... The other computer in my house hasn't been turned on all night.

I am working with XP pro, SP 2. Linksys WRT54G router. I do know how to access the router settings etc, but not what to do from there. I don't wanna mess things up before I even get started.

If someone could give me details on how to resolve this I would be very very happy. I am so frustrated with it.
