is wireless adapter like tht will pickup signal from 2 to 4km or more range, so tht i can set up to use free wifi internet from neigbouring by cracking in to the network , wht is the best wireless adapter available in market , i can invest up to 500 dollar for buying this (if such a product is available) or do u have any idea to get highspeed internet like 3 mbps free 
, currently am using 60kbps unlimited internet for 11.1$ per month , and here isp donot provide unlimited highspeed internet , i got a lot to download , it will be like 66$ a month for 2mb unlimited , so is there an adapter powerful tht will let me use login to net from Wifi signal aorund my town , or in my appartment building , I dont know if people in my appartment use wireless internet or not , when i used my laptop with wireless lan it didnt show any signals ,
am from India
