A few updates ago, the Wi-Fi and Bluetooth, which were working perfectly after
previous fixes for the Realtek RTL8821CE 802.11ac, have become unstable again.
Wi-Fi constantly drops, and Bluetooth has poor and choppy audio. I noticed this
problem occurring after a few updates because everything was working perfectly
(there were problems in the LTS version in the past, but they had been fixed,
and in 23+, there were no issues until now). The process is as follows: I boot
up the system, Wi-Fi works for a few minutes, then it drops, and no adapters
are recognized. I reboot the system. Sometimes it works perfectly, other times
the same issue repeats. Bluetooth doesn't drop, but with headphones, the audio
keeps cutting out and is of low quality. I've observed this for about a month.
Thank you for your attention.
