Question: Is WPA3 supported?
|
||||
|
||||
Answer: WPA3-SAE is supported. It works well on most modern 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 (distros released after mid 2022) or
|
||||
compile and install new versions of wpa_supplicant and/or Network Manager.

Answer: Many new and existing Linux users already have adapters based on

Question: I have an adapter with the 8821cu chipset and it supports
|
||||
bluetooth. The bluetooth works but the wifi does not. What is wrong?
|
||||
|
||||
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
|
||||
directory:
|
||||
|
||||
```
|
||||
sudo ./edit-options.sh
|
||||
```
|
||||
|
||||
Once in the document, you can scroll down to the documentation about
|
||||
`rtw_RFE_type`. You will likely have to experiment to find out what setting
|
||||
works best for your adapter but a good place to start is probably...
|
||||
|
||||
```
|
||||
rtw_RFE_type=7
|
||||
```
|
||||
|
||||
Simply add that option to the end of the `options` line, save and reboot.
