Hi Nick,

I installed your driver just as described and tried to run aircrack-ng with it.
Everything went perfectly up until I ran the following
sudo aireplay-ng --deauth 0 -c <client mac> -a <ap mac> wlan1

I always get the following error msg:

Waiting for beacon frame.... on channel 100
wlan1 is on channel 100, but the AP uses channel 2

(My problem is that I cannot set the interface to use another channel)
I already tried changing the channel using:
sudo iw dev wlan1 set channel 2 HT20
but it just stays the same

I also tried this on another PC as well as without concurrent mode without success
I managed to switch it to channel 1 by reinstalling with concurrent mode but that just gave me the same error msg, as expected

Thank you in advance
Fabian

Hi,

Using a RTL8811au chipset wifi dongle, I am unable to enable WDS so I can create a real bridge with the RPI 3B ethernet adapter or internal Wifi adapter.

root@raspberrypi:~ # iw wlx1cbfce25609c set 4addr on
command failed: Operation not supported (-95)

I've seen this issue posted earlier, but not fixed yet. Any idea how this can be solved?

I'm trying to use an Edimax EW-7811UAC (containing RTL8811AU) in monitor mode on a Raspberry Pi and it appears it is staying fixed to channel 1 in the 2.4GHz band. airodump -c 11 or airodump -b a are always returning channel 1 data for example. iw list lists all the expected channels in the 2.4 and 5 GHz bands, but iw wlan0 set channel 11 produces command failed: Device or resource busy (-16) while the interface is not in use, not even by network managers. I have enabled ARM support during the build process and the interface appears to be working, except channel switching.

Hi,
i´ve used your installation guideline, but i got the following error:

Honestly i am a newbie to manjaro an Linux, only know a little commands. And with this, i can´t help out myself. Would you be so kind and tell me what to do?

Thank you so far!

Hi there! After spending many hours going through drivers, I finally thought to just search Netgear A6100 in github, and saw this as being the most up-to-date. It works! Thanks for your great work!

Right after sending the command to install the drivers, this message appears in the terminal:

Error! Your kernel headers for kernel 4.9.277-76 cannot be found.
Please install the linux-headers-4.9.277-76 package,
or use the --kernelsourcedir option to tell DKMS where it's located
An error occurred. dkms build error = 1
Please report this error.

Sorry if my interaction on Github isn't correct, it's like the first time I'm using it.
My PC board: Odroid C4;
My OS: Ubuntu Mate 20.04.3 LTS;
Wi-Fi dongle: Cudy UW600
Wi-Fi dongle chipset: something between rtl8821cu and rtl8731au.

Hi,

I'm not familiar with 802.11 or usb protocol, and I have a question about the endian.

my PC is debian and driver build config CONFIG_PLATFORM_I386_PC=y and this -DCONFIG_LITTLE_ENDIAN is enabled.

In rtw_recv.c, when get a raw 802.11 frame, driver use GetFrameType(ptr) to get frame type, which is:

#define GetFrameType(pbuf)	(le16_to_cpu(*(unsigned short *)(pbuf)) & (BIT(3) | BIT(2)))

le16_to_cpu() means data read from usb is little endain. While when I read other library that parse 802.11 header, they usually use ntohs() which means the origin data is network endian(big endian).

This confuses me, so the header endain is depend on the device self or os system type ?

I've got the usb wi-fi dongle D-Link DWA-X1850 https://wikidevi.wi-cat.ru/D-Link_DWA-X1850_rev_A1
Being optimistic I simply tried to build the driver by adding the following line to os_dep/linux/usb_intf.c under #ifdef CONFIG_RTL8821A

    {USB_DEVICE(0x2001, 0x3321), .driver_info = RTL8821}, /* D-Link - DWA-X1850 */

When I connect the dongle I see these messages in syslog:
Mar 16 16:22:12 condor kernel: [ 3228.702391] rtl8821au 1-2:1.0 wlx00e04cec2869: renamed from wlan0

Can I do something else to get the driver working for my new dongle?

I have installed the driver 3 times on new installs and on 2 different sd cards and I still cannot get it to work with my Netgear ac600 the driver installs normally and after installing the device isn't used for wlan

Request that you test and report any problems. Specific bugs should be reported by opening a new issue. Discussion can go here.

Hi

As the tittle says, it doesn't work on more recent kernel versions.
Although it installs OK, it doesn't seem to start.
I'm using Kubuntu 21.10
I have to boot with kernel .40 to work.

Thank You

Trip over this again, Odd, this time a simple reboot did not fix the issue. This was on Pi Zero, but not sure that matters.

Since the install-driver.sh failed, I ran the remove-driver.sh, did not reboot and did a make clean then make, just so see what happened, and this was the result:

Really weird, since the correct headers are there.

I am only able to connect to 2.4ghz, when I connect to 5ghz it just keep on asking for password. I made a detailed description on Tplink routers forum because I don't know if its the wifi dongle or the router that has the problem.

Hi,
I am tinkering with a RPI4 and a A6100, but as soon as I plug in the A6100 things go downhill :-| - Basically any iw and uname command as requested for the issue report cause cause some lockup as seen in the syslog dump below. Anyone have experience with this kind of behavior? Is it my kernel version that is unsupported - Any tips for debugging?

I am using wlan0 for connecting to wlan - So I would like to keep that enabled and then use the A6100 for testing.

Can I install my TP-Link Adapter on wlo2 interface?

Hi there!
I hope you are going great!
First of all I would like to congrats all people evolved on this project you are amazing!
Thank you all!

So, my issue is a sudden stop of the wifi. I'm using a dungle USB TP-Link Archer T2u AC600 dual band. However, I don't know why the internet connection sudden stop on my Xerolinux OS and when I touch the wifi icon the internet returns to work in a few seconds.
I use the same dungle on Windows and I have no issues at all.
My question to you guys is there a setting on the rtl8821au config file that I could do to sort it out or some?
Thank you in advance!
Be fine out there!

does this support kernel 4.14.180

i made module 8821au.ko
without dkms

i am getting following error if i try to run

insmod /vendor/lib/modules/8821au.ko

Hi. I have tried to install the driver on kernel (5.15.0-41-generic), but it doesn't seem to work.

Thank you.

I have 2 adapters and the one showing wifi unavailable in the screenshot above is the tp link one with this driver. The LED light is blinking slowly.
Any help would be appreciated.

I'm with Ubuntu 20.04.3 and when my wifi is on channel is 157, I can't connect to 5ghz.
With Windows I don't have any issue.

I have an TP-Link Mini - AC600 USB 2.0 (Archer T2U Nano)

I'm using a TP-Link Archer T2U Nano and I cannot connect to certain Wi-Fi AP. My phone does connect just fine, and when I check the frequency, it was on channel 157 which is disabled in the driver according to iw phy0.

I have tried changing iw reg, but this did nothing to improve the channel situation.

Not an issue just to add a line to your list of tested distributions. I have used this driver successfully in openSUSE Tumbleweed since last August (previous version first, this version now).

openSUSE Tumbleweed is a rolling distribution that is continuously upgraded, so a number of kernel versions have come and gone since last August. All of them have worked flawlessly. Current kernel is 5.15.2.

The WiFI adapter is a generic USB dongle based on RTL8811AU (0bda:a811 Realtek Semiconductor Corp. RTL8811AU 802.11a/b/g/n/ac WLAN Adapter).

Thank you for this effort, much appreciated!

I reinstalled Solus Linux, but when I tried to build the driver, after installing all the dependencies, it didn't build

Hi! I did installation as instructed (except enabling Concurrent Mode; Edimax doc. did not mention it).
No errors. Seems to have worked. DKMS status returned:

rtl8821au/5.12.5.2, 5.19.0-23-generic, x86_64: installed

Bluetooth worked out of the box (no driver needed) but WiFi is absent. I moved the dongle to another port in the back but was not successful either.
My system uses Ubuntu 22.10, so kernel 5.19. Is connected through cable too.
Might have to do with Linux 5.19? Or related to that concurrent mode?
I really appreciate your help.

I searched all of the issues and don't see how to fix this. The USB dongle is wlan1 in the following. Any help will be greatly appreciated.

OS: Arch Linux x86_64
Kernel: 5.19.2
Device: RTL8821AU

It worked perfectly with kernel 5.19.1

Same issue with aircrack-ng/rtl8812au (this issue)

Not an issue, but wanted to indicate that this has worked great on my odroid n2+ 64bit arm sbc from hardkernel. I'm running "archdroid" which is essentially alarm (arch linux arm) with an additional set of helpful device specific packages such as the tobetter patched kernel with panfrost gpu driver and other odroid specific changes. None of the changes should affect the network subsystem, it's essentially a 5.13 mainline kernel.

I did run the raspiOS-64.sh script beforehand. Not sure if it was needed, but it seems to work fine.

Linux squirt 5.13.16-1-ARCH #1 SMP PREEMPT Thu Oct 14 13:55:45 AST 2021 aarch64 GNU/Linux

To start with, I want to thank you for this piece of work. It works for me K5.15.

I am using TP-LINK Archer T2U USB wireless adapter to take sniff using virtual machine (vBox).
Thanks to your driver I am seeing this within my VM as wireless card.
But, when it comes to taking this to monitor mode, it seems not working.
I opened this just to ask your recommendations or maybe it is a driver problem i dont know.
However, wireless card supposedly supports monitor mode.

My dystrohop turned me on to Alpine Linux, but I can't compile a driver for it
Here's what I did:

git clone https://github.com/morrownr/8821au-20210708.git
apk add make g++ linux-headers
cd 8821au-20210708
sh install-driver-no-dkms.sh

I can build the driver for the 8811AU device (CONFIG_RTL8821A=y), but I need to also build for the 8811CU part at the same time (CONFIG_RTL8821C=y). When I also enable CONFIG_RTL8821C=y, the build fails with rt8821c.mk: No such file or directory.

Can you update the driver source to support the rtl8811CU part?

i can't be able to enable wlan0 with this driver... : (

sry i know this proably not the right place but , i gotta ask i bought tp link t2u plus (rtl8821au) , should i return it and get the one with rt5370?

tp link has both 2.4 and 5 .0 hz support while other doesn't, they both cost the same, and other options are too costly in my region?

Alright! I'm ready to get this AP as efficient as possible if you're up for it still.

IP: Spectrum (sadly)
Devices Connected: iPhone X, M1 MacBook Air, Motorola Z4

What is everything else you need to know?

This issue is related to the following issue in the older repo:
https://github.com/morrownr/8821au/issues/19

I installed the newer driver and tried again:
dkms status reported rtl8821au, 5.12.5.2, 5.11.0-36-generic, x86_64: installed

The good:

• This driver is functional for both wpa_supplicant and hostapd, on the system described in the above link.
• When using this driver in the client mode (wpa_supplicant) to connect to an external AP, connection can be established (and according to tcpdump -i RTL8811AU_DONGLE_INTERFACE while issuing ping -c 20 -f -I RTL8811AU_DONGLE_INTERFACE AP_ADDRESS, ping traffic works. (Still an ethernet cable connected, so not performance-tested, but this is a step I could not get to work with the older driver at all.)
• When using this driver in the AP mode (hostapd), it still works more or less as before.

The bad:

Some minor problems were detected:

• For some reason, wpa_supplicant seems to be not quite compatible with this driver, since I never got wpa_cli -i RTL8811AU_DONGLE_INTERFACE to work. The error was "Could not connect to wpa_supplicant: RTL8811AU_DONGLE_INTERFACE - re-trying". (I do not think the older driver worked here either, but am not 100% sure I tested it.)
• When starting wpa_supplicant, there is still the same error in dmesg, or according to journalctl: "wpa_supplicant[851254]: nl80211: kernel reports: Authentication algorithm number required". But it seems to work (see above), so this must be minor.
• Incorrect, see below: Despite rtw_drv_log_level=0 in /etc/modprobe.d/8821au.conf, The dmesg log is severely spammed (2-3 seconds between each) by messages such as "[191259.082604] RTW: rtl8812_sreset_xmit_status_check REG_TXDMA_STATUS:0x00000401" during normal operation. Note that it says 8812, not 8811 (which matches my chipset) or 8821 (which is the name of this driver).
• Incorrect, see below: Despite rtw_drv_log_level=0 in /etc/modprobe.d/8821au.conf, during start of either wpa_supplicant or hostapd, it seems every step of the setup process is logged there too, with "RTW" as a prefix in dmesg.
• The default output power in the AP mode, as reported by e.g. iw phy#2 channels, was not higher than +13 dBm in any of the 5 GHz channels, which is lower than the older driver reported. The older driver supported up to +31 dBm for some (not all) of the 5 GHz channels.

The last issue above is annoying, but not really a stopper, since a command such as this can be used to increase the output power if needed: iw phy#2 set txpower fixed 2000
Note that higher output power is not always better, but that is a completely separate discussion

I bought this USB wifi adapter to use with my Raspberry Pi 3 and installed your driver and rebooted, but the adapter is still showing up as unclaimed in lshw:

Hello, I wanted to install your driver on Solus Linux, but there is a problem: DKMS was cut by the creators of the distribution: Quick
How then to install the driver?

Hello,

I cannot get this driver to work. The device I am using the driver with is:
ID 7392:a812 Edimax Technology Co., Ltd Edimax AC600 USB

The 8821au driver compiles as a module for 5.15.13 using clang-13.0.1, but produces several warning messages. It installs and loads fine, and it shows up as a device with iw and also as a network device with ifconfig.

However, when trying to run a scan using the command iw dev wlx... scan does it produce the error command failed: Network is down (-100).

hostapd in AP mode starts, it initialises and also recognises an incoming connection on the device, but then appears stuck and a full connection never gets established (no DHCP information gets exchanged).

When compiling the kernel and 8821au driver with gcc-11.2.1 can I get as far as running a scan on the device and produce a list of the surrounding WiFi networks unlike with clang. hostapd however still fails even when using gcc-11.2.1.

When I use the rtl8812au AirCrack-NG driver (v5.6.4.2) with gcc-11.2.1 does everything work fine. I can see surrounding WiFi APs and I can connect with various devices to my own WiFi AP and access the local network as expected.

I appreciate any suggestions you have. My main goal is to find a driver for this device, which compiles with clang and supports most if not all of it features.

On a minor note, the rtl8812au AirCrack-NG driver reports somewhat different device capabilities than this 8821au driver:
