How Can I tell if someone else is using my wireless connection?

I have recently had someone move in to my residence. I set up a wireless security key but I still think they were able to get in. Does anyone know how I can check to make sure that my IP address is the only one using wifi. I have an ATT 2wire modem.

    You would have to get onto your router/modem through the administration interface and see what IP addresses are using it. Sorry, I don't know the specifics of that modem so can't give you much more than that.

    Well, you can check all your device up addresses, then go to command prompt and type in "ipconfig"

    And go to ipv4 address

    Copy that address and paste it into your web browser

    Go to it and there should be something like "home network" if you can't find it just look around

    Now look at the devices on the screen. If they don't have names, match the ip addresses. If you have a device that you don't think you own change your password and put it onto the highest security setting possible (for modern routers that is WPA2)

    you can check from homepage of the modem.

    as example you can check for the THOMSON modem from the" 10.0.0.138 "

    then you can go to " Home Network "

    in wireless how many user there.

    better way you can make the access from the " MAC Address "

    and make username and password for the homepage for homepage for the modem it self.

    Good luck.
