Good evening, I’m new to the forum, I hope you can help me, I’m a beginner. I am on a LAN network equipped with an access point that broadcasts the wireless network. You can access the network with a free connection, as soon as you connect the authentication page opens (I think it’s captive portal) and everyone accesses the network with their credentials. One of these access points broke, and I’m using a Mitrotik access point instead. I connected it to a LAN socket and it generates the wifi signal, and everything works perfectly. Only today, however, did I notice a problem. If I access the network generated by the access point (free network) and enter my credentials in the captive portal page on the browser, anyone who connects to the network after me will be able to navigate without the need to enter their credentials in the captive portal, and this is not good. Likewise, if I disconnect, all those who were connected to the network generated by Mitrotik will disconnect. How can I solve it? Thank you all.
