 There is a problem that the live video playback on the Apple terminal in a certain site freezes

On-site use of Android terminals and PC terminals to play live video is very smooth. Through the display wlan client mac xx verbose on the AC, it is found that the signal strength RSSI of the Apple terminal is very good, but the sending rate in the tx direction has always remained at the lowest rate of 6.5M. By default, the packet between the AP and the terminal is sent at the highest negotiated rate. When the packet transmission fails, the packet will be sent at a lower rate, and so on, until the terminal receives the packet. Currently, the packet sending rate in the tx direction of the AP is only 6.5M, indicating that a large number of terminals fail to receive packets.

Solution:

Considering that the Apple mobile phone does not support frame aggregation technology well, try to configure a-msdu disable (priority disabled) in the radio view of the ap to disable frame aggregation. After closing the frame aggregation, the Apple terminal plays the video smoothly, and at the same time, the rate of the tx direction has changed to 866M through dis wlan clien mac xx verbose.
