Greetings to all,
we have a Wi-Fi system in a building based on Cisco C9800-L-F-K9 and AIR-AP1815I-R-K9 access points. Periodically one client, Apple iPhone 12, loses connection with SSID and it cannot connect. We have enabled Radioactive Trace by its MAC address. In the file, I received some messages that seem suspicious to me. Could you tell me if these messages are normal client operation, or if there is a problem at this point?
Below are some excerpts from the log files:
