Hello, I'm trying to update this page to add info on Debian 11 that this dongle worked with, but when I click Save the information I entered is not saved.
Works in Debian GNU/Linux 11
creato da 0mid, 19:27, 15 maggio 2022
------------------------------ 2022-05-15 ------------------------------
On Debian GNU/Linux 11 (with only the main archive enabled), with kernel Linux 4.9.0-15-amd64, libre firmware installation was straightforward:
sudo apt install build-essential libelf-dev linux-headers-`uname -r` dkms
git clone -b v5.6.4.2 'https://github.com/aircrack-ng/rtl8812au'
cd rtl8812au
sudo make dkms_install
Vendor id and device id are below (not what's registered above):
ID 2357:011e TP-Link AC600 wireless Realtek RTL8811AU [Archer T2U Nano]
No modprobe was required after firmware installation and the WiFi dongle started working right after being plugged in. On my "50Mbs/10Mbs", the 5GHz band delivered 58Mbs/12Mbs. On 2.4 GHz, it went up to 35Mbs/10Mbs. Connection was stable in both cases with no issues with hours of heavy use.
Thanks for the report

I'll take a look later today.
Might be fixed

Sorry for the very late response. I attempted a fix on the server and just managed to add Debian GNU/Linux 11 bullseye to "tested on". Do you mind trying editing again?
Nonfree firmware blob?

The arrays at https://github.com/aircrack-ng/rtl8812au/blob/v5.6.4.2/hal/rtl8812a/hal8821a_fw.c look like source-less firmware blobs. Does anyone know if source code is available for these? If not, the hardware should probably marked as not working, right?

I looked at the aircrack-ng Github repository and it shows as being forked from a different one - https://github.com/astsam/rtl8812au - the hal/rtl8812a directory shows no similar firmware files in this one, though it hasn't been updated since 2017. I did a search on Github as I'd recalled finding other repos on there while looking for drivers - https://github.com/gnab/rtl8812au - this one also doesn't contain those files. I'm not sure how to properly check for blobs but hopefully this helps.

Unfortunately both of those repositories seem to contain other blobs (or maybe the same blobs in different places; I didn't check).

See https://github.com/astsam/rtl8812au/blob/master/hal/phydm/rtl8812a/halhwimg8812a_fw.c and https://github.com/gnab/rtl8812au/blob/master/hal/OUTSRC/rtl8812a/HalHWImg8812A_FW.c .

I found these by cloning the repositories and running `ls -R | grep -i fw.c` from the root of the repository. That won't necessarily find all blobs, and if the firmware was actually in source form that would find non-blobs, but that seems to be the fastest way to find firmware blobs in Realtek drivers, at least.
