I'm setting up a WiFi network for a small NGO here in Bolivia, so it means we are trying to do it on the tightest budget possible.
The site comprises 2 buildings about 100 meters apart from each other. We want to have one WiFi access point in the main house, connected to the router which is connected to internet. This AP will be used for the computers inside this house.
Then we want to have a second AP in the second house, acting as a repeater (looks like WDS - Wireless Distribution System is the way to go here.) The antennas of both devices would be put outside the window with a direct line of sight between them.
Finally we want to have both wireless AND ethernet clients to connect to the second access point, and access internet via the first AP.
So the question is : is this achievable with common consumer WiFi Access Points/Routers ? Or is some more specific hardware required ? Keeping in mind that money is not flowing here and we would rather spend it on schoolbooks or medicine than expensive hardware ;)
