Wi-Fire Long Range WiFi Adapter from HField

USB Wi-Fi Antenna for Long Range Pickup
Compact, Range Extending USB Device - Special Wi-Fi Directional Antenna

How it Works:
The Wi-Fire uses a powerful directional antenna, highly
sensitive receiver and proprietary software to find and
enhance normal WiFi signals. With it, you can connect
wirelessly to the Internet faster and with a stronger signal
than an internal wireless adapter can achieve

The Wi-Fire draws very little power from your laptop
battery. It comes complete with everything you need to
connect wirelessly to the Internet. Just install the driver
software, plug in the Wi-Fire to a USB port, and you're
ready to start. It can rest flat on any surface or clip
securely to a laptop display or flat screen monitor

The Wi-Fire connection Manager reveals all available
networks in the area - more than you've seen without the
Wi-Fire. Simply rotate the Wi-Fire to maximize the signal
strength for one of your desired networks, select the
strongest publicly accessible network (or private netwrok
for which you have authorization) and then click connect.
You're now connected in places you never were before!
Enjoy your new freedom and convenience.
