Association with the AP usually takes a long time (but finally succeeds) and I'm very often getting site loading errors when surfing the internet. After having successfully started a large download (which may require multiple attempts), it usually "gets running" and the performance isn't too bad. I've tested kernels 5.14 to 5.16-rc5, but there is no difference. However, since 5.16-rc dmesg shows some    rtw_8821ce 0000:02:00.0: failed to get tx report from firmware messages. Apart from that, there are no errors in the log. I also tried module parameter disable_aspm=1 without success. Please let me know what you need. Regards, Frank
