(info) Is 8822cu also supported?

[SunboX]

Will this driver also work with the 8822cu chipset?

[morrownr]

No. You are the first person I have had contact with that has an adapter with that chipset. I would need source code and an adapter to add support. It may not be easy to find the source. The retailer that I am usually able to find source does not carry any adapters with that chipset so does not have the source available.

Maybe I can look into supporting this chipset but I may need you to help track down the source. There is also the in-kernel driver for this chipset. As of kernel 6.2, there is an in-kernel driver. The performance is not that good yet.

If it were me, and you are still able to return it for exchange or money back, that is what I would do. The best chipsets, if you have no alternative but Realtek, is the rtl8812bu and rtl8811cu chipsets. If you have the option, get an adapter with a mt7921au or mt7612u or mt7610u chipset as those chipsets use in-kernel drivers.

Look for menu item 2 at the following link for a good list of adapters based on the above chipsets:

@birdofprey
You got 8822cu with this driver to work with both antennas?

[morrownr]

@waddisdis

birdofprey may think he got this driver going with an adapter that uses a rtl8822cu chipset but that is not the case.

He is using Debian 12 with kernel 6.4. That distro with kernel 6.4 has an in-kernel driver for the rtl8822cu chipset so it should work in a plug and play manner.

While I am writting, let me point you to the Main Menu of this site. It has a lot of information for Linux users wanting to use USB WiFi adapters on Linux:

At the above repo, you can use Issues to to ask questions and read news.

Hope this helps.

Hello @morrownr ,

I am facing the same issue and am looking for a driver for the RTL8822cu chipset.
My kernel: Linux 5.15.136-tegra (Ubuntu 22.04)

Is there a driver available yet?

[morrownr]

Hi @ADV-LUT

I suggest you test the rtw88 driver as outlined in the first message at this link:

morrownr/88x2bu-20210702#224

We need reports from uses of the 8822cu. Please pay attention to usb3 and usb2 support and if you need instructions, let me know.
