Question: Is WPA3 supported?
Answer: WPA3-SAE support is in this driver according to Realtek and it
works well on some Linux distros but not all. Generally the reason for
WPA3 not working on Linux distros is that the distro has an old version
of wpa_supplicant or Network Manager. Your options are to upgrade to a
more modern distro (most distros released after mid 2022) or compile and
install new versions of the wpa_supplicant and Network Manager utilities.

Question: I have an adapter with the 8821cu chipset which means it supports
bluetooth. The bluetooth works but the wifi does not. What is wrong?
Answer: There appears to be a hardware bug in some 8821cu based adapters
and the fix is to set the driver option ( `rtw_RFE_type` ) in 8821cu.conf.
Answer: There appears to be an issue where adapters can be set up differently
by makers. The fix is to set the driver option ( `rtw_RFE_type` ) in 8821cu.conf.
The easiest way to edit 8821cu.conf is to run the following from the driver
