I would like to write a mini web-app to control clients' internet access on a Wifi-router.
How can I block/regulate their Internet usage while connected to the router?
Each client would have a login username & password. I do not want to use a MAC-address filter as they could login using any device.
For wireless access control, look at a RADIUS server. From Wikipedia:
Remote Authentication Dial In User Service (RADIUS) is a networking protocol that provides centralized Authentication, Authorization, and Accounting (AAA) management for users who connect and use a network service.
A free RADIUS server: http://freeradius.org/
It's supported by some of the better consumer access points, such as the ASUS RT-N66U.
