Streamed videos in 1080p for an hour, and downloaded a 600 MB file; both worked beautifully. There was no buffering and no CTRL-EVENT-BEACON-LOSS log messages. Tested with laptop using ath9k driver and Qualcomm Atheros QCA9565 / AR9565 Wireless Network Adapter.
Using my laptop's Wi-Fi to stream videos is a big failure with a, Qualcomm Atheros QCA9565 / AR9565 Wireless Network Adapter.
My Acer Aspire E1-570 laptop's log repeatedly contained the message
wpa_supplicant: wlp3s0: CTRL-EVENT-BEACON-LOSS
This stable kernel update, and the 2 previous kernels all have the above ath9k driver regression
The 5.16.17-201.fc35.x86_64 scratch kernel build, fixes the above ath9k driver regression for my laptop; and I don't have to revert back to kernel version 5.16.14-200.fc35.x86_64, to get perfect Wi-Fi video streaming.
