Linksys Ethernet (local network) problem

[Mockery]

We've got a linksys wireless ethernet installed here. Right now it's just myself and Re's computer on the network... but recently there have been times when another person's computer has appeared on the network. I was able to get in and view his files 'n everything.

Now I thought this shit wasn't supposed to be able to happen, but sure enough, it's happening. I don't have anything secret on the network... I never keep important files of any kind on there. Still, I want this guy OFF the network permanently.

Any suggestions on how to do so?

enable wep on the router config then config the wireless systems with the key.

Cover the outside of your house in chicken fencing to keep out all unwanted radio signals.

But I'm already wearing a tinfoil hat to keep the demons out. Isn't that enough?

And big thanks to whoreable... problem solved. :o
