Thank you

Thank you for your answer

Now I can’t access by mobile. If I access at room with devices are same vlan it’s running perfect. But I access at room with one device with WLAN and other devide with data mobile, the mobile device doesn’t access.

By default, only two clients will try a peer to peer connection. If one client is inside and one is outside, that doesn’t seem to work. If you go into the mobile client advanced settings, and disable PtP, does it work better?
