With my new Macbook I find 54 wifi networks in my apartment (See the first page of them in picture below). it is crazy. With my iMac or Powerbook I found only like 9. The antenna is that much more sensitive on this new Macbook. Now I have to find out how many of them are open with good signal strength. I also need to make sure my own wifi network is not getting bad signal strength because it is sharing a channel with too many nearby networks.
