USB Wifi adapter with very long range/strong signal ?

Hi all !

What USB wifi adapter will allow me to "catch" free public connection which is about 250 meters away ?

I was trying an Edimax EW7711usn 3db adapter which uses an external antenna, and can get faint signal from the source when directing the antenna in the "correct" direction. However, when I try an EW7622umn (which doesn't have an external antenna) I see more network but can't see the free spot 250 meters away...

I need one which is very strong and can catch this up ;)

Yes, Super Cantenna is a very good solution, and fits any Wifi card or Wifi dongle with antenna connector.
