### FAQ
|

|
||||
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.

Question: I bought two usb wifi adapters based on this chipset and am
|
||||
planning to use both in the same computer. How do I set that up?
|
||||
|
||||
Answer: Realtek drivers do not support more than one adapter with the
|
||||
same chipset in the same computer. You can have multiple Realtek based
|
||||
adapters in the same computer as long as the adapters are based on
|
||||
different chipsets.

|
||||
|
||||
Question: Why do you recommend Mediatek based adapters when you maintain
|
||||
this repo for a Realtek driver?
|
||||
|
||||
Answer: Many new and existing Linux users already have adapters based on
|
||||
Realtek chipsets. This repo is for Linux users to support their existing
|
||||
adapters but my STRONG recommendation is for Linux users to seek out USB
|
||||
WiFi solutions based on Mediatek chipsets. Mediatek is making and
|
||||
supporting their drivers per Linux Wireless Standards guidance per the
|
||||
Linux Foundation. This results in far fewer compatibility and support
|
||||
problems. More information and recommended adapters shown at the
|

Recommendation: If this is an important capability for you, I have tested
|

Mediatek adapters for this capability and it does work with adapters that

use the following chipsets: mt7921au, mt7612u and mt7610u.

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
