Public Wifi network, no internet

RouterOS Wireless Networking
1

Hi,
I want to use my mikrotik router on a public network. (normally, when you connect to this network a pop-up comes up, and you have to log in).

When I connect to my network, I can go to the page via the PC to log in, this also works successfully, but I still don’t get internet. Someone ideas to solve this?
