Hi, I retested the version from https://github.com/lwfinger/rtw88 on linux 5.10.16 - starting with the commits on Mar 9, 2021. It now seems to work pretty fine even on 2.4 GHz / 40 MHz! Thanks to Realtek for their support! Additional credit goes to Larry Finger, who thankfully provides this additional source tree to make the progress of the driver accessible to a lot more kernels than the actual one!
