Need Testers: New in-kernel (mac80211) driver for rtl8821au, rtl8811au and rtl8821ae chipsets.

[morrownr]

New in-kernel (mac80211) driver for rtl8821au, rtl8811au and rtl8821ae chipsets.

Information about testing is located at:

morrownr/8821au-20210708#133

That is Issue 133 in the 8821au repo here at this site. That issue will be used for discussion and reporting. The first message shows the location of the driver to be tested. The subject chipsets have been popular with Linux users for several years.

The intent is to upstream the driver to the Linux kernel once it is ready. There is nothing like Plug and Play adapters that work well. Please help if you can. I have been testing managed and monitor mode today and the results are good. We need to test rigorously.

HOT: All devs currently only have adapters with rtl8811au chips. We need Linux users with rtl8821au and rtl8821ce chips.

My TP Link T2Uv3 (USB ID 0bda:c811) should be qualified for testing? And which kernel version I need to use to test?

Hi @fakemanhk

(USB ID 0bda:c811) should be qualified for testing?

We can certainly use your help testing but I need to give you a different link than the one above. You adapter uses the rtl8821cu chipset which uses a different driver than the one shown in the subject but it just so happens we already have an updated version of the driver for your chipset that needs testing also. The driver is located at:

https://github.com/lwfinger/rtw88

Follow the instructions in the README.

Below is the location of the issue where you should report bugs or suggestions:

morrownr/8821cu-20210916#115

And which kernel version I need to use to test?

5.4 or later. If using 6.2 or later, you will need to blacklist the driver that is already in the kernel.

I found that I also have a few other Realtek based USB wifi at home (some are unknown brand), not sure if any testing needed for them?? I am listing the USB ID below:

1. 0bda:b812 (this should be 8812BU?)
2. 2357:011e (T2U Nano, probably this is the 8811au you want to test?)

2357:011e (T2U Nano, probably this is the 8811au you want to test?)

Yes, indeed. ID 2357:011e /* TP Link */

That is a rtl8811au chipset. We could use help testing the other one when the time is right but for now we need to get the new driver in the kernel. Go back to the first message and follow the link to get info on the location of the driver and to see what is going right now.

How is the testing on the adapters going?
