When we will see better client isolation
Right now one area that the TP-Link AP's aren't strong in is client isolation - something that is pretty critical for hospitality environments.
As everybody knows the "guest network" setting is very deceptive and will only prevent layer 3 communication between devices on the same AP. To prevent layer 3 communication between devices across multiple AP's you need to create an EAP ACL rule to restrict access to other IP range(s).
There does not appear to be any way to configure proper L2 client isolation - if I run Fing on a network I should not be able to see the MAC addresses of any other devices. This is core functionality across every other brand of WiFi hardware.
When will TP-Link focus on these areas? The guest network setting should be fixed so that it does work properly and limit all L3 traffic on the same network, and that capability should also be extended to isolate all traffic at L2 level discovery level as well.
