Hello there,
I am still studying about all this and i am thinking and search for setting up a wi-fi connection in my locality for lets say 3 houses near each other.

Now i would like to know how am i able to provide each "customer" a login/pass to connect to my wi-fi connection with Bandwidth limit, Connection limit like 128kbps and like MRTG Stats if possible.

I am able to connect and to provide wi-fi connection access points and hot spots with the hardware needed and antennas.
