a friend of mine has cable a few blocks away...i was there using my notebook on his internet connection (we were watching youtube stuff) i came home and my notebook found a wireless connection that isn't mine...i connected to it and asked him for his 2 IP addresses for his 2 computers. one ended in 100 the other in 102. our IP addresses were the same except for the last 3 digits...mine is 101. so mine seems to fit between his 2. does that mean that i'm picking up his wireless signal from about 6 blocks away? (he lives on a hill and its fairly wide open between here and there)
