Hi

I am trying to add your driver to a Raspberry Pi kernel at build time. I am doing this as follows:

• Diff your sources against /dev/null to generate a patch.
• Patching drivers/net/wireless/Kconfig to include your driver at build time.

I can see and select the module in make menuconfig. I have made the necessary changes to the Makefile to allow for Pi building.

When I build the kernel and run make modules, I do not get a rtl8812au.ko file but do not get any errors either.

My patch is here: https://raw.githubusercontent.com/samnazarko/osmc/master/package/kernel-osmc/patches/rbp-008-add-rtl8812au.patch and should apply against 3.18.5.

Hi, apologies if this is not the right place to ask but is there a way to change the LED behavior?

I have compiled the driver to be used on a Raspberry Pi with an Edimax EW-7811UTC
AC600 Wireless Dual-Band Mini USB Adapter. It works fine, but the LED is constantly blinking, even when there is no network activity.
I don't know if this is the normal expected behavior but this is particularly annoying in a dark room (e.g. when sleeping at night).

Is there a way to change the source code to change the LED blinking behavior or eventually to turn it off?

I have had a look at the files in the repository (in particular the ones which seems related to the LED) but I lack programming skills and I could not figure out what eventually I should change.

Thank you.

Hi,

I'm trying to use aircrack on ubuntu with this driver but i have an error so if anybody can help it would be great :)

Here's my error :

$sudo airodump-ng -t wep wlan0
ioctl(SIOCSIWMODE) failed: Invalid argument

ARP linktype is set to 1 (Ethernet) - expected ARPHRD_IEEE80211,
ARPHRD_IEEE80211_FULL or ARPHRD_IEEE80211_PRISM instead. Make
sure RFMON is enabled: run 'airmon-ng start wlan0 <#>'
Sysfs injection support was not found either.

Thanks

Hi, compiled module on pi as per your excellent instructions.

I have some issues around performance and while trying to dig about I noticed these messages.

Is this normal ??

I am using arch on model B+

hope you can help

Hi, no idea where to start with this, so I'll describe my setup:

• Raspberry Pi
• Arch Linux (4.0.8-3-ARCH)
• USB 3.0 Powered Hub
• Alfa AWUS036ACH USB 3.0 Wireless Adapter
• tried both this driver and the fork by @csssuf https://github.com/csssuf/rtl8812au
• hostapd 2.4 with the RealTek driver patch https://github.com/pritambaral/hostapd-rtl871xdrv
• the above hostapd build with the noscan patch https://dev.openwrt.org/browser/trunk/package/network/services/hostapd/patches/300-noscan.patch

Everything is fine when connecting near the antennas, however when I'm further away say through a few walls the signal is still good but there is huge packet loss, to the point where google (for example) just won't load. The strange thing is I don't get this problem when I connect the adapter to my Windows Desktop and use the RealTek software

So I thought I would post an issue here and see if anyone had any solutions.

Thanks
Aaron

I tried just doing make on my Raspberry Pi and it failed because ARCH needed to be "arm", not "armv6l". I added a symlink, but it appears I just need to edit the Makefile and change the CONFIG_PLATFORM_ARM_RPI to y. The step for configuring should be added to the README somewhere.

Hi,
I am getting periodic network freezes with the original driver and also with your fork. This is mostly visible in networked real-time games where the action just freezes for a while, and then continues. It lasts 1-5 seconds. Have you noticed similar behavior? Any ideas on how to fix it?

Thanks for your great work making this possible on 3.11 👍

I can make it work in AP mode in either 2.4GHz or 5GHz band. When compiled with CONFIG_CONCURRENT_MODE it creates two devices and I can run a hostapd on each of them
(one configured for 2.4GHz channel and one for a 5GHz channel).
However when the second hostapd starts it always sets both devices to the same channel.

Seems like "concurrent mode" only means you can have one AP and one STA in parallel.
Does RTL8812AU support simultaneous use of both bands in general?
As it is flagged as AC1200 both radios should be able to operate in parallel.

I'm trying to compile this driver for Linux 3.12.26, and in the middle of running make, everything goes fine until this error message pops up:

make[2]: *** No rule to make target `[directory]/hal/led/hal_usb_led.o', needed by `[directory]/8812au.o`. Stop.

What is this error?

I'm using the RPI config to compile for a Marvell Kirkwood ARM processor on ArchLinux ARM with the command strnicmp replaced with strncasecmp mod in os_dep/linux/rtw_android.c

It builds, module loads, but plug in the dongle and I get what I think is a paging issue (see below). Is this caused by strncasecmp ???

The driver crashes and I have to unplug and replug the adapter, an Alfa Networks AWUS036AC.

I think this is the latest version of 8812au driver.
I don't know if it has better performance than 4.2.2.

Please add support for above USB Dualband WLAN Adapter!
Thanks!

To compile on Odroid C1 (ARM, Kernel 3.10, gcc 4.8.2, Ubuntu).
I had to change the Makefile:
-SUBARCH := $(shell uname -m | sed -e s/i.86/i386/)
+SUBARCH := $(shell uname -m | sed -e s/i.86/i386/ | sed -e s/ppc/powerpc/ | sed -e s/armv.l/arm/)

Then simply make and make install.

Under kernel 3.13.0-24 compilation of driver fails, reports asm/bitsperlong.h file is missing

I am running Kali 2.0.1 on a Raspberry Pi 2. Anyone know why this might happen? And yes I did turn off I386 and on arm rpi. Thank you for your time and I hope to hear back from you shortly!!

What's the difference between this repository and https://github.com/abperiasamy/rtl8812AU_8821AU_linux ?

Hi,

I'm using your driver with a small change to compile on kernel 4.x and I have trouble with rdesktop when using 5GHz (802.11ac). rdesktop is not connecting at all or if it's connecting it freezes most of the times
after login.
Any idea on how to fix it ?

thanks

Using the driver in this library together with the AWUS036AC containing the "Realtek Semiconductor Corp. RTL8812AU 802.11a/b/g/n/ac WLAN Adapter"(lsusb output) I could not get Ad-hoc working. I did not test any other functionality and I'm not well versed in C so I did not dig that hard through the source. However, by using the driver found on Alfa networks site: http://www.alfa.com.tw/download_show.php?combo_0=&combo_1=&combo_2=&keyword=awus036ac&verify=7rrkpx&x=0&y=0 (driver direct link: https://www.dropbox.com/s/6uruc5og6xw1877/rtl8812au_linux-master.tar.gz?dl=0) and adding the if statement about Raspberry Pi compilation from this project, I got the device running and Ad-hoc mode working. Just thought I would throw that out there in case there are any significant changes or additions in Alfa network's driver.

My development platform is Debian x64 and I would like to build this x64.

Hello

I am trying to build driver for Bpi, but I can't. I tryed to build on laptop (core 2 duo) and on bpi, but I can't. I installed driver for i386 without any problems, but for arm, I can't. I changed only two lines.
CONFIG_PLATFORM_I386_PC = n -> from y to n
CONFIG_PLATFORM_ARM_SUNxI = y -> from n to y . I think, it's correct platform

I see the message

Błąd 2 -> error 2

Any plans to make this module build using the standard linux command for building modules:

make -C linux-3.4rt M=$PWD ARCH=mips CROSS_COMPILE=mips-openwrt-linux- modules

Is this module available yet as part of mainline linux source tree somewhere?

could you please add a license to the code?

Hey I tried using the make install method but i get the followoing error:

Please can you help me sort it out or point me in the right direction thanks.

Hi!

I'm going to make the Access Point by using the rtl8812au device driver on Ubuntu.

Is it possible to make the AP by using this device driver?

I did not find out this method.

If it is possible to make the AP by using rtl8812au, please notice to me.

Best regards,
Woojoong Kim.

I read there had been issues running rtl8812au on ARM devices. Maybe this is one of them

Using ODROID C1+ with kernel:

Builds fine.

When starting wpa_supplicant it forver tries to associate. There is this sequence in the syslog:

The same dongle and same code tree works fine on x86_64 machine with kernel 4.1.13

Please let me know what kind of debugging I may perform on my ARM device to contribute
Thanks

I had to edit os_dep/linux/usb_intf.c and comment out line 1995 to compile with kernel 3.14.2. This is explained in patch codeworkx/rtl8812au_asus@a3ddf29 (which cannot be merged directly as this repository has a different file structure).

Otherwise there will be massive amount of logs of the driver put into dmesg, it impacts the performance quite a lot.

The installation was smooth and my adapter is working great, thank you very much. However, even though it sees my 5.0 band and connects to it, speedtest.net only shows up to 25mbit download speed whereas on windows the same adapter and connection goes over my maximum of 75mbits. Could you please look into this?

I'm willing to help if I can get a bit of a start, but I'd like to run some of the monitor utilities (aircrack-ng, wash/reaver, etc.) on these, especially with 5GHz support. I'm not sure if the chipset has support.

Also, the "iw" program can - on supported cards - create multiple virtual interfaces per physical interface, and depending on hardware, one can be an AP, another monitor, another client.

http://wireless.kernel.org/en/users/Documentation/iw/vif/

This might let me use one device for both my AP and upstream connection, and/or two APs, one on each band, etc.

I am using an Asus USB-AC56 wireless adapter which also utilizes this driver.
It successfully built & loaded the code by gnab and the adapter successfully connected.
However I discovered that it has very limited range: if I am in direct line of sight of the router, it will work with high dowload rate - however if slightly removed, it goes down considerably.
i.e. with the device in the same physical location I can achieve ~ 45 Mbps (Internet Speed Test) in Windows vs 1-2 Mbps in Linux. But if I move to a closer proximity, the performance is comparable.
Similarly, with the notebook in the same physical location, I get high download rate with the internal adapter in Linux, vs limited with the USB-AC56

Now - I notice on the Asus web-site, they have newer driver rev 4.2.5 available here:
http://support.asus.com/Download.aspx?SLanguage=en&m=USB-AC56&p=11&s=1
In the application notes is says
"Update MAC/BB/RF parameters and mechanism to improve overall performance" so I am curious if this will address the range issue.

However the 4.2.5 will not load - the release says for Kernel support 2.6.18 ~ 3.10 - I am running 3.11.
Does this have the same issue that was outlined re the proc entry API?
I'd be keen to try 4..2.5 to see if that resolves the range issue.

Thank you for your development in this area - it is much appreciated!

Hey @gnab! Nice of you to maintain this driver.

I followed the instructions and ran make on my station. I have the forementioned dongle in my PC. make ran wonderfully, insmod no problem but for some reason my Trendnet still doesn't want to play nice.

No occurence in iwconfig, ifconfig, network manager etc. I even installed it and rebooted to make sure but still nothing.

If you can shed some light on this I'd really appreciate it.

Cheers mate!

I tried to compile this driver for my Raspberry 2 but I run into the following error.

The code for line 257 looks about right... anyone know what the problem might be?

Hi,

Perhaps it is necessary to add discovery of Edimax EW-7811UAC to 8812 and not 8821?

I have an Edimax EW-7811UAC, and I am typing this using this device as the wifi adapter, so - success! But, I needed to modify usb_intf.c.
Now, I'm not a developer - and hence haven't much clue what I'm doing, but - when I compiled the driver using the original usb_intf.c and installed the module and updated dependencies, no light flashed on the device and Mint 17 network management showed wireless with a cross. iwconfig showed everything off.

So, I added:
{USB_DEVICE(0x7392, 0xA813),.driver_info = RTL8812}, /* Edimax - EW-7811UAC */
to the #ifdef CONFIG_RTL8812A section, and - hey presto - it worked!

I did this because lsusb returns:
Bus 002 Device 011: ID 7392:a812 Edimax Technology Co., Ltd

Therefore, perhaps it is necessary to add discovery of this device to 8812 as well?

Sorry for any technical misunderstandings, J

Any ideas?

I downloaded driver about one month ago. After install and using wlan card as primary internet connection, my kernel crashed. LED on wlan card was off. It happened few times every few days (every 4-10 days).
I couldn't check it, because my server doesn't have monitor. After reset I checked in log files and all logs stopped the same time, so I think it was kernel panic.

I commented out all debug messages (based on issue "Suggest turning off the debugging log by default") and installed driver again. Since about 2 weeks, my server working without any problems.

I tried to set wifi mode to "Monitor", but it prompts "Invalid argument"; if I set mode to "Ad-Hoc", then it worked. I jus want to know the chipset rtl8812 isn't support this feature from hardware, or this driver isn't support it.

The following is error message.
[root@localhost Downloads]# iwconfig enp0s26u1u6 mode Monitor
Error for wireless request "Set Mode" (8B06) :
SET failed on device enp0s26u1u6 ; Invalid argument.

Hey,

i'm getting a couple of errors when im trying to build the module.
Here's a log:
makelog.txt

When i plug in my wifi stick EW-7811UTC it is recognized, but i can't connect to any network.
Here is a log from the attempt to connect (dmesg | grep RTL871X):
connectlog.txt

I experience this bug on many new Kernels 4.2+.

Any idea how to fix this?

I am trying to cross-compile the Edimax EW7811UTC driver for Arch Linux-3.4.103 in Ubuntu. But I am always getting the following OUTPUT without any error and 8812au.ko file.

OUTPUT:

$PWD : is the driver directory

I tried the native Arch Linux compilation as well and the output is same as I mentioned above. Any help regarding the above is much appreciated.
