It is highly dependent on the antennas being used, their orientation, whether there is line-of-sight and if not, the type of building materials in between, and transmitter power.  802.11b and g has a typical range of 150 ft http://www.mobiletechreview.com/tips/wifi.htm

rcatach,

There are a lot of factors.  Two real big ones are indoor vs. outdoor and which wifi protocol (i.e. A, B, G, etc).  Other factors are the settings of the router.  Can you provide more details?

If you want really general then I would say 30 meters indoor conditions and up to 100 meters outdoor.  This can really differ by protocol though.

Let me know if you have any questions or need more information.

How about a mile or two outdoors.

You can always achieve longer distances if you use a directional antenna.  Some have used a Pringles can, for example, but I think a mile or two is stretching it; a thousand feet would be more practical.

You beat me to it, Callandor. I used to have wireless broadband, before I was able to get fiber. It was basically 802.11b that communicated with a tower a few miles away. The biggest limitation, from what I understand, is that you have to have true line of sight; apparently the signal doesn't go through trees very well.

It did require special equipment, though. It wasn't a standard 802.11b receiver. It was a big square antenna that sat on my roof.

That is an interesting link that Callandor provided.  One caution though is that 2.4GHz has become a VERY common frequency and it would be easy to get interference from other devices.  That will lower the range.  Thoffman just mentioned one of the points I was going to make about getting optimal range, line of sight and an external antenna.  I'm glad that I refreshed before posting this.

External antennas can make a big difference.  In a pinch, I once used a not very strong directional antenna on the top floor of a hotel and was able to get line of sight connectivity for 802.11b in a tent maybe 1500-2000ft away in a resort town.

I've also worked on hotel networks where an AP is in one unit, and one or two units away doesn't get signal.  Various building materials can affect it as well.  If you mount an AP up against a metal stud in a wall, not much signal is going to make it out behind it!

I found out that it needs to be around 2,300 feet away from Business to the owner’s house the Business is at the high point in the city with a line of sight to the house. And would preferably be under $700 dollars.

Using 6ft dishes a 300km link has been demonstrated using off the shelf wifi radios.

Believe it or not most wireless list ranges of about 1100 feet (assuming
no walls in the way).  However,  SMC Corp.  makes an Elite series that
has a range of 2100 feet.  Now I do not believe either of these stats but
the SMC certainly has a much farther range due to the power levels
it ttransmits (the highest in the industry for non commercial transmission).  If you are on the edge of making the distance I suggest
you try the SMC.  It has worked great for many of my customers.
