I'm staying at a friend's house for a bit. He lives on the top floor and he has lent me a room in the first floor. Now, his wireless signal is not too good in the first floor, and he asked me for my "IP address" to input into his router's system and allow the signal to be strengthened. I'm not sure how to look for this, and I'm not even sure about the terminology. Can anyone help me out here? (I'm a tech/Mac/computer buff, not a network geek) Any help will be appreciated. UPDATE: After I've scrounged around in System Preferences, I found my AirPort ID from the AirPort networking preferences, and in the form 00:xy:yx:yy:xy:yx where the x's are numbers and the y's are letters. Is this the one?
