    You can get similar devices with the declared 500mW power and -93dBm sensibility 3 times cheaper.

    You should get one that connects to a satilite dish sort of antenna. There have been reports of getting wifi signals from 10-30 miles away with those kind of wifi adapters.

    I need one that is portable and that is plugged in by usb. I can work with it if it has to be AC/DC powered.

    Between theses two.

    2.

    The first is up to just over a mile range and the 2nd is up to 1000 meters. (.6 mile) Is the change in sensitivity the cause in loss of range?

    This one I have seen recently,
    http://www.dealextreme.com/details.dx/sku.18884

    but there are many others (one brand name I remember is Alfa, try to google for Alfa, USB, wi-fi 500mW or search on ebay; another one I know is Senao).

    The shop above also has wireless range extenders and 9dB omnidirectional antennas for very good price:

    The shop is based in HK, but it worked well for me.

    PS: I ask Tibetians and Uigurs to forgive me for advertising a Chinese shop.

    Total waste. They're using increased power because it's a Wireless G adapter, so they need to add the power to extend the range. You'd get the same or better by using a Wireless N or Dual-Band Wireless N adapter, which would give you similar range, using less power and a much faster data rate. 108mbps with a Wireless G adapter?? That'll be the day. In a lab maybe...

    You have to be kidding me if N gets that range. And at range N is barely faster then a good G router. Plus the reason of getting this is to find a hot spot no matter where I am instead of having to pay for a data plan. And not everyone has an N router.

    Using more power on the laptop only increases the distance you can transmit from. If you don't increase the power on the router too, you won't get any benefit. The best performance is when you upgrade the antennas on both the remote machine AND the router, or failing that, a much better antenna on at least the laptop/remote machine. Directional, and a higher sensitivity.
