Hey guys,
I have the above listed model from tp Link.
I set up a guestnetwork for my costumers with the FB(facebook) authentication.
Its working good except some apps like facebook, instagram etc can access to the internet without that FB login.
I red an outher article here in this forum but for me its not clear how i can prevent them to communicate with the Internet before i do the login.
Can someone help me and give me a detailed instruction for dong think.

Many thanks
