Question

Computer networks

Hello.
We want to take a regular (budget) / medium router into a small room, on which we could set up a welcome page when a client connects to the network.
Tell me, please, which routers support this feature?

Answer 1

Mikrotik. And set it up and if you still want checkers, there will be where to swing.

Answer 2

Any that can flash on dd-wrt / tomato, for example. Or a higher price segment with native firmware that can Captive portal.
