both ios and android have same problem, I have tried been close to the AP . Certain video player apps are slow. For example the youtube apps on my phones will take like 15 seconds to load the thumbnails . Im not sure if its my set up since im not very experienced in networking. I just have my modem connected to my wireless router with the radios off and then the AP connected to the router. I can reboot everything and it seems to solve the problem but after 3 days it starts to slow down.
