Receiving then sharing wireless
Slightly off topic perhaps but networking nonetheless -
A good friend of mine lives in a little Spanish village and the local 'council' provide free wireless internet connectivity at the 'Town Hall'. Village residents can simply go there with their laptops and use the free wi-fi as much as they need.
His house is about 100 metres from the Town Hall, and conveniently has line of sight to the building in question, and more importantly, the wireless broadcast antenna thereon. Unfortunately, he can't get a signal when in his house as the walls are about 20 foot thick!
He would like to a) fit a wireless receiving antenna onto his house, and then b) share the subsequent wireless out to 3 computers in his house.
Point A is relatively straightforward of course, but B is a little more out of my current knowledge.
What does he need to be able to do 'B'?
Obviously there'll be an antenna on the roof, cable down into the house, and then... ?
Advice on a complete setup would be very much appreciated.
