At my institute, the administration has a 5 Mbps speed cap per user. Each user needs to enter his/her credentials (username and password) before he can access the internet. I have bought a TP-LINK 150 Mbps Wireless N Router (TL-WR720N) recently. When I connect 3 devices to that router and enters my login credential at any one connected device (out of 3), the login credentials are not required in the other 2 devices and the speed (5mbps per user) gets divided into 3 devices. This does not happen in case of other routers. How can I configure the router so that the login page appears on each of the connected devices and the speed is not divided?
