The Cisco 2100 Wi-Fi controller, which has been configured for many years and worked flawlessly, stopped processing Mac Filtering — with the settings below, the devices do not connect to the Wi-Fi network, although they see it. (windows could not connect to the network, it also does not connect from the phones)

Layer 2 - security none, only Mac Filtering is enabled. Addresses are listed on the Security, Mac Filtering page. Hammered in correctly, before that everything worked. Layer 3 - security none, if Web Policy is disabled - devices are not connected, if enabled - does not work out Mac Filtering and the device falls on the login page.

If you turn off all security settings at all, the network works fine. What could be the problem?.

General Layer2

The problem got away. Apparently there was a plug somewhere else.
