I just would like to add my (newbie) observation on the similar problem (maybe it can be useful for developers). I have laptop "HP ProBook 455 G7 (1F3M4EA)" with WiFi card RTL8822CE. My system is LinuxMint 20.2 with kernel 5.13.0-23-generic.
I noticed that old routers with 2.4 GHz work fine with laptop (i.e. wifi problems happens rarely, one a day or less). But in the case I use modern router with 5GHz (fibra, optical line) I have the following issue. From time to time, wifi networking is stopped. Network manager in tray shows wifi is connected but with 0% power. With 90% of probability it happens when I use speedtest site. After this happens I can not reconnect, I can not restart network manager and then reconnect (I tried restart it by different ways I found in internet: systemctl restart network-manager ; sudo killall NetworkManager ; sudo ifconfig wlp2s0 down , sudo ifconfig wlp2s0 up; sudo systemctl restart NetworkManager.service ...) only reboot allow to use wifi again. After wifi stopping I see the dmesg output contains a lot of lines like these: [12259.905821] rtw_8822ce 0000:02:00.0: timed out to flush pci tx ring[1] [12260.053680] rtw_8822ce 0000:02:00.0: timed out to flush queue 0 [12260.197672] rtw_8822ce 0000:02:00.0: timed out to flush queue 1 [12260.337653] rtw_8822ce 0000:02:00.0: timed out to flush queue 2 I also tried to follow the suggestion: "Setting /etc/modprobe.d/rtw88_pci.conf to contain options rtw88_pci disable_aspm=1" It does not help. Another dmesg log - disconnection happens with 2.4 GHz router. Only reboot helped: ...

card. Now at hirsute, this is "supported" in the linux-image-5.11.0-16-generic kernel,and it works "well" for both WiFi and Bluetooth. However, this module (driver) causes frequent freezes, randomly but usually within a few minutes of running (thus very soon after boot): screen display remains frozen, no response to either keyboard or mouse input. All I can do is to hold the power button to power off, then reboot. After reboot, I do not see any crash reports, nor logs about the freeze. Please let me know if I should try to collect some info, and how. For now I use the DKMS module/driver from https://github.com/tomaspinho/rtl8821ce (having blacklisted rtw88_8821ce), and it seems to work perfectly.
