I have seen this limit 2007 devices for AP somewhere else in documentation, my config now has max_num_sta=255 I have also switched from "g" mode to "b" and it seems that this is working more stable. I have also set ctrl_interface so I can see STA being disconnected and connected. For now it works fine with 70 devices. I need this to work in buses, where every seat has a device build into it and it is communicating with server. So bus has around 80 seats. If I will have to I can add two physical AP's but it would be good to control these from one server.
