    I see in the airport extreme menu that there are 3 wireless clients yet there are only 2 that are connected in this house. I see the DHCP client, is there a way to block them?

    You can use Access Control. Under the Airport tab then Access Control sub-tab. Just enter the MAC address of the offending computer and change it to Timed Access. Just make sure you check it again regularly, because it can be circumnavigated easily.

    password protection ...


    Via the airport utilities, you can password protect access to your wifi. Use WPA or WPA2, but by doing so, you limit leachers.

    My wifi has always been encrypted. WPA2. I'm not dumb enough to leave it unprotected.

    Ok, then it sounds like one of two things:

    You have another device in your house that is wifi - AppleTV or an Airport EXpress or a computer with two wifi devices hooked up. How about an iPhone/ipod touch/ Ipad?

    OR, your password is known to someone else and you need to change it.

    Lastly, and this is tedious at best, take a look at the entires there and jot down the MAC addresses (they are listed as: 00:58:AF:...) and check your devices to see what is connecting and what isn't.

    Good luck!

    It's probably one of your own devices that draws wifi signals. If you don't have an easy-to-guess password, I doubt people would pick up on the password.

    My password is 32 characters of jumbled letters. :p I'll try the suggestions in this thread, thanks.
