I want to set up a wireless network that would work over a distance of about 2 or 3km, is there a cheap way of doing this and having encrption as well?

Wont work out of the box that far. You can use the coffee can trick, but then you'll be breaking the law I think

 

Erm, yes it will

I've installed WLAN backbones for sites up to 3km. I know one install covered 2.3km as we measured it using a GIS plot from the local council.

Using Cisco kit, you'd be looking at using Yagi 12.5dBi directional antennas with a good line of sight. A tried, tested and legal solution.

Any idea of likely cost for this setup you mention chris?

Well if you're talking kit, then yes, I assumed common-or-garden ADSL modem which will not transceive that far on its own, especially through walls

 

Ahh, horses for courses is true Steve

You'd be looking at £2000 to £3000 for the hardware.

 

Hello

If you have line of sight, then the cantenna solution mentioned above will work fine.

I've been playing recently as it interests me and I can get that kind of distance with a dog food can and some modifications to my wireless network card.
