### 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
following site:
https://github.com/morrownr/USB-WiFi

Question: Will you put volunteers to work?
Answer: Yes. Post a message in `Issues` or `Discussions` if interested.

Answer: This [article](https://null-byte.wonderhowto.com/forum/wifi-hacking-attach-usb-wireless-adapter-with-virtual-box-0324433/) may help.

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.
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
to run the following from the driver directory:
