Long-range wifi?

Does anyone have a good idea how to do a long-range wifi network?
I have a great hotspot program that uses a linksys router
I currently am running it, but with only 3 clients, not making much profit.
If some one has an idea on how to boost my signal so i can get more houses in my range and make more $$ =]

Thanks in advance

 

So you are stealing internet? lol. i do the same thing. i think you need to buy a stronger router....

 

buy a good external wireless card with antenna like netgear

 

Buy yourself a 5 decibel wireless adapter. They're high gain.

 

im not stealing the internet, im selling it to my neighbors
i was doing some research on it, so if i get a few dbi gain, it should work
im thinking like an 9dbi omni-direction, and if i get two of them, i can put one on oneside and another on the other side of the house

 

thanks for the tip

 

Yeah your need range boosters. What ISP plan you on?

 

I have an amazing comcast connection, and i use a linksys wrt54g router, with dd-wrt firmware.
i have 1 range extender, but its totally not worth the money
im thinking about buying some pannels and put them up in my room.

 

oh yeah, i can't put the range booster anywhere else besides my house
i got one on the oppside of the house, but like i said it does nothing
