rtl8812au_8821au_linux's Issues

Bad connection quality

Using Ubuntu kernel 3.19.0-16-generic, I can compile and install without any issue. However, signal quality is very bad:

wlan1 Scan completed :
Protocol:IEEE 802.11bgn

Frequency:2.452 GHz (Channel 9)

Quality=0/100 Signal level=23/100

On a different linux machine (Mint kernel 3.13.0-24) I can use the standard driver from Alfa web site, and I get very good connection quality.

No background scanning

First of all, thanks for porting the driver to newer kernels :-)

There seems to be a major issue (Ubuntu 14.04, linux 3.13) where every 2mins NetworkManager scans the network. Each time this happens, packets are delayed - I don't see drops but ping time skyrocket to 3000ms for about 3secs.

I've contacted Edimax twice and they've not bothered to reply so there's now a warning on https://wikidevi.com/wiki/Edimax_EW-7822UAC

DKMS: install completed. How do i load the device now

Hello, this is not really an issue but more a question , the build was successful on arch xfce, now how do i load the card and scan for networks

do i need to modprobe anything

Connected to Wifi, but no ping to router - Netgear AC6100

Hi,

I already explained the problem at askubuntu.com.

But here is the problem in short:
Ubuntu on 3.13.0-46. Compiled, and loaded the driver. iwconfig shows the right ESSID, ifconfig shows the right IP, route shows that wlan0 is used, but there is no answer to ping 192.168.1.1 (router).
I can add lsusb, etc. if you need it, but perhaps this is a very easy issue.

TIA

Cyoux

Low range performance

I am using an Asus US-AC56 which also uses the Realtek driver
However I discovered that the 4.2.2 has very limited range: if I am in direct line of sight of the router, it will work with high transfer rate - however if slightly removed (to adjacent room), 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 in Linux is comparable.
Similarly, with the notebook in the same physical location, I get high transfer 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 believe 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.

When tested in a kernel <3.10, the 4.2.5 driver definitely works MUCH better - has considerably improved speed when operated at a remote distance (the issue I was seeing with the 4.2.2)

However will not work into 3.11 kernel. It appears to build and install however the USB adapter does not work and additionally it causes system errors once the driver is loaded (when the USB is plugged in) - the Terminal will not accept commands, the software manager nor driver updater will open, nor the file system and the system will not shut down - just hangs.
So it definitely does not like to be used in 3.11 Kernel!
However in 3.08 it installed and operates flawlessly and indeed also resolves the range issue.

I can confirm I tested in Linux Mint 15 just using internet speed test as a quick reference:
Close line of sight proximity to router - 48 Mbps (55 peak)
In another room (through walls etc) - 39 Mbps (44 peak)

With 4.2.2 build, in the same remote location as above, was only 1-2 Mbps (but same as 4.2.5 when close proximity)

Summary - 4.22 has a range issue - 4.2.5 definitely resolves the range/transfer rate issue however will not work in 3.11 kernel.

So - if you can work some magic on 4.2.5 to enable it run on the 3.11 kernel, that would be fantastic!

5Ghz Issues

Hey guys, it seems that 5Ghz does not work. I am using an Alfa's AWUS036AC adapter and an ASUS AC56 to test this driver. In clarification, I can see my 5Ghz network, but cannot seem to connect to it about 80% of the time. When I do, the connection is not that stable.

For example, my ASUS RT-AC66U Router has two networks
NetworkTheta - 2.4Ghz (this works all the time)
NetworkTheta5Ghz- 5Ghz (can always view as stated above, rarely connect)

I am actually using gnab's repo right now, and the issue I posted is right here
gnab/rtl8812au#2

I am using Fedora 21 Workstation x86_64 with the latest kernel (at the time of this post 3.19.3-200.fc21.x86_64)

the dmesg of a successful 5Ghz connection: https://mega.co.nz/#!rVUiAYiJ!6vpJra9s8LnexQ92i5NF0YsgCKPM4C4-Z195f46btMk

the dmesg of a failed 5Ghz connection: https://mega.co.nz/#!PM9y2AxI!8oxhR19pmJvk2TAjyunmcT6Npi1NoMiTwRU8AgtWXEk

Thanks in advance!

Failed in compiling.

I was compiling the driver under ArchLinux on Raspberry Pi 2
uname -a

Linux meow-archarm 3.18.13-2-ARCH #1 SMP PREEMPT Mon May 18 20:19:37 MDT 2015 armv7l GNU/Linux

Error:

hostapd low performance

I used the hostapd to create 11n AP mode with this rtl8812au driver. but the bitrate is desperately low (20mbps) .Do you any idea about what I should do to have better rate.

Following hostapd configuration is used:
ctrl_interface=/var/run/hostapd
bridge=br-lan
auth_algs=1
ignore_broadcast_ssid=0
wpa=2
wpa_passphrase=11111111

and (iwlist scan) output:

Do you any idea about what I should do to have better rate?

Compilation fails in 3.18.5 and .6

Looks like the parameters to cfg80211_rx_mgmt have changed again again :-)

The flags parameter added in 3.12 is still there, but the gfp parameter has been removed:

[root@hagrid kernels]# grep -A 1 "bool cfg80211_rx_mgmt" */include/net/cfg80211.h
3.17.8-200.fc20.x86_64/include/net/cfg80211.h:bool cfg80211_rx_mgmt(struct wireless_dev *wdev, int freq, int sig_dbm,

3.17.8-200.fc20.x86_64/include/net/cfg80211.h- const u8 *buf, size_t len, u32 flags, gfp_t gfp);

3.18.5-101.fc20.x86_64/include/net/cfg80211.h:bool cfg80211_rx_mgmt(struct wireless_dev *wdev, int freq, int sig_dbm,

3.18.5-101.fc20.x86_64/include/net/cfg80211.h- const u8 *buf, size_t len, u32 flags);

3.18.6-100.fc20.x86_64/include/net/cfg80211.h:bool cfg80211_rx_mgmt(struct wireless_dev *wdev, int freq, int sig_dbm,
3.18.6-100.fc20.x86_64/include/net/cfg80211.h- const u8 *buf, size_t len, u32 flags);

This will thus need a fix for include/ioctl_cfg80211.h for the #define

bcdUSB 2.00

The device misreports, under Ubuntu 14.04 x64, as bcdUSB 2.xx, rather than bcdUSB 3.xx. This can be observed in the output of lsusb -vv post-driver compilation. I assume the respective Windows drivers do something to coerce the device into behaving as a proper USB 3.0 device. Can the same thing be achieved as part of this driver?

Edit 1: This user seems to be having the same issue: https://bbs.archlinux.org/viewtopic.php?pid=1398049#p1398049

Edit 2: This user also has the same issue: http://askubuntu.com/questions/389477/edimax-ew-7822uac-not-operating-at-superspeed

Patch b22cbdf breaks WPA2 passphrase authentication

b22cbdf patch breaks authentication validation on my machine, using WPA2 passphrase. Up to f1008f6 the driver works fine. I use an Edimax AC1200 USB adapter and a Netgear R7000 router under dd-wrt. What info do you need to diagnose the problem? Thanks.

What's the difference between this repository and https://github.com/gnab/rtl8812au ?

New device support

I found these cheap usb ac devices on ebay. They are from a company called Outlink. It's basically like an Edimax A811 but with a different vendor id. WIth this line it does not work, with the line it looks like it works.

Unknown symbol cfg80211_*

Hi guys,

After compiling the code on RPi with Raspbian 3.10.36+ for a Netgear A6100 (8811AU) I got the errors below in my syslog. Did I miss something or is this expected? (Note: I got my device working with similar driver code in GitHub, such as https://github.com/gnab/rtl8812au and https://github.com/sblommers/rtl8812au) but I would like to get your version working as it seem to be the solution to get the hostapd thingy working, right?

In any case, thanks for your effort.
Cheers
Gossie

How to install this driver

i did make and the make install
when i run runwpa it says failed to open wpa1.conf : no such file

sporadic performance

I am not sure if this is a driver issue but I have not seen anyone else with the problem so I am noteing it here.
I have been using the Edimax EW-7822ua with the rtl8813AU driver and it will at times work amazingly, stream hd movies etc, then randomly drop to bites per second. All other computers on the network are not suffering from this. It occurs on both the 5ghz and 2.4ghz ranges.

I am happy to supply any info required

compile warnings on 3.13

In os_dep/linux/os_intfs.c

if you change

static u16 rtw_select_queue(struct net_device *dev, struct sk_buff *skb)

static u16 rtw_select_queue(struct net_device *dev, struct sk_buff *skb, void *accel_priv, select_queue_fallback_t fallback)

It gets rid of a few compiler warnings. It's been a while since I did C so I forget what happens when you call a function with wrong number of arguments.

I'm also wondering why it compiles os_dep/linux/rtw_android.c ? on x86?

TP-LINK Archer T4U on Ubuntu 14.04. ping time spikes exactly every 120 seconds

I'm using TP-LINK Archer T4U wireless adapter on ubuntu 64 bit with rtl8812AU_8821AU_linux. I cloned the latest source from the repository as of yesterday (6 Sep). I notice that every 120 seconds exactly, I'll experience a spike in the ping time, as high as 4000 ms (normal ping time is about 8ms). I don't know what's going on here. The same machine running Windows 7 with the same wireless adapter using the stock driver for Windows does not have this problem.

VHT Support not advertized to cfg80211

Even though the driver supports VHT, it is not being advertized to the cfg80211 hence we see wrong VHT capabilities in the beacon.

Have a patch ready, but not sure how to submit.

rdesktop is not connecting or freezes after login

Hi,

I'm using your driver on kernel 4.0.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

Compilation in Arch Linux Kernel Version 3.4.103

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:
make: Entering directory /home/nagarjun/linux-sunxi/cubie/sunx7i_22'
LD /home/nagarjun/Desktop/EW7811UTC/built-in.o
Building modules, stage 2.
MODPOST 0 modules
make: Leaving directory/home/nagarjun/linux-sunxi/cubie/sunx7i_22'

COMMAND:
make ARCH=arm CROSS_COMPILE=${CC201310} -C /home/nagarjun/linux-sunxi/cubie/sunx7i_22/ M=$PWD

Where,
${CC201310} : is the cross compiler path, which was set properly
$PWD : is the driver directory
/home/nagarjun/linux-sunxi/cubie/sunx7i_22 : My Arch Linux Kernel Source

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.

8812au: disagrees about version of symbol module_layout

I'm getting the following error message when trying to load the module for this edimax adapter:

https://wikidevi.com/wiki/Edimax_EW-7822UAC

Compiling inside a Raspberry Pi (no cross-compiling).

root@rpi:/usr/src/rtl8812AU-git# modprobe 8812au
ERROR: could not insert '8812au': Exec format error

In dmesg:

[ 2593.836183] 8812au: disagrees about version of symbol module_layout
[ 2616.580796] 8812au: disagrees about version of symbol module_layout

I've followed the following blog post:

https://www.debinux.de/2014/06/sitecom-wifi-usb-adapter-ac1200-treiber-dkms-einrichtung-unter-ubuntu/

But I had to do a:

# ln -sf /usr/src/linux-headers-3.12-1-rpi /lib/modules/3.12.22+/build

Which I guess it's the root of the problem, but since the exact linux-headers for my running kernel version (3.12.22+) are not available, I thought that 3.12.x linux-headers would be enough.

Any pointers on how can I circumvent this issue?

I have purchased D-Link DWA-171. I pulled down the sources from master branch and found that my card DWA-171 (13d3:3394) was not represented in os_dep/linux/usb_intf.c. I added an entry just above DWA-172 corresponding to the USB vendor and device ids of my card, built, installed and restarted to get a wireless interface corresponding to DWA-171.

My issue is that 802.11n works just fine, but 802.11 ac has issues when accessing some websites (i am writing this ticket using 802.11ac). The following is what I observed in tcpdump:

Sometimes (strangely I can reproduce this consistently when accessing the above mentioned url), the packets in case of 802.11ac are shown are corrupt 'IP truncated-ip - 4 bytes missing!' and this causes a failure to load some websites, while other websites seem to work fine.

I have seen this problem with both Ubuntu 14.12 kernel and now with 3.19.0-22-generic as well. How do I debug this further?

Does not compile (gcc: error: unrecognized command Werror=date-time)

Hey, even if I remove this line (-Wdate-time) from the makefile I get further errors and the compiler says the Function "cfg80211_rx_mgmt" is not declared.

Question: AP support in 5ghz?

I ask because I recently bought the Intel 7260 which has a firmware restriction on using the adapter in AP mode. Has anyone tried using hostapd with this one with 802.11AC?

Linux kernel 4.0.5 regression

Both rtl8187 drivers from here and from [0] don't work with the D-Link wifi adapter 2001:3314. The devices are registered with xhci and mtp tests (which fail in 4.0.4 too), but no device will appear. It does work in linux 4.0.4 but I don't know the codebase enough to investigate myself.

My distro usually ships vanilla packages, please let me know whether you can reproduce the issue.

Linux 4

Hi,

I was wondering if you are going to update the drivers so that they are able to build on linux kernel version 4.

Tried building on both of my linux boxes got the following error:

make ARCH=x86_64 CROSS_COMPILE= -C /lib/modules/4.0.2-gentoo/build M=/root/wireless_drv/k4/rtl8812AU_8821AU_linux-master modules make[1]: Entering directory '/usr/src/linux-4.0.2-gentoo' CC [M] /root/wireless_drv/k4/rtl8812AU_8821AU_linux-master/os_dep/linux/ioctl_cfg80211.o scripts/Makefile.build:258: recipe for target '/root/wireless_drv/k4/rtl8812AU_8821AU_linux-master/os_dep/linux/ioctl_cfg80211.o' failed Makefile:1390: recipe for target 'module/root/wireless_drv/k4/rtl8812AU_8821AU_linux-master' failed make[1]: Leaving directory '/usr/src/linux-4.0.2-gentoo' Makefile:1040: recipe for target 'modules' failed

Rasp 2 B w/ 4.0.7 works - iw station dump doesn't work

Hi,

on my Rasp 2 with linux-headers 4.0.7, I compile and running with TP-Link T4U
It works!!!!
Very quick!
ac Mode!

:-)

But .... when I use the 8812au.ko, the "iw dev wlan0 station dump" gives me nothing :-(
No information with this command - when I change the Stick / Realtek or so, it works.

I forget to turn on some parameters in Makefile ????

Best regards

Support Linux 4.0.0, change enum NL82011 flags to match upstream chan

Hi,
I am not able to determine what changes have been made to what files with the patch titled "Support Linux 4.0.0, change enum NL82011 flags to match upstream chan.."

For example, for rtw_ap.c it shows "3,179 additions, 3,179 deletions" which looks like the patch is "delete the old file entirely and replace with new one". I would like to know which lines have been changed.

I am using a driver that I got from Edimax at the back end of 2014 called rtl8811AU_linux_v4.3.7_11618.20141029. I was sent by email from edimax support as there latest driver. I have made some very minor changes to run on Rpi and it works well, even at 5G although there are issues.

Find it here https://www.dropbox.com/l/ZG4Zrxgr6cwYOrfhbm4YOp

It is possible that it is a better base than the older one you are using. I would like to apply the patches for Linux 4.0.0 and NL82011 to my version to see if it works better but cant determine what the line by line changes were. Can you help ?
regards

Raspberry Pi2 Installation problems (Raspbian)

Hi,

I just want to ask if somebody can support me.
I tried to install the driver under Raspbian 3.18.11-v7+ #781, I followed the steps discribed here:
sudo apt-get install linux-image-rpi-rpfv linux-headers-rpi-rpfv dkms build-essential bc
ends up with the message:
ln: failed to create hard link /boot/initrd.img-3.18.0-trunk-rpi.dpkg-bak' => /boot/initrd.img-3.18.0-trunk-rpi': Operation not permitted update-initramfs: Generating /boot/initrd.img-3.18.0-trunk-rpi
if I ignore this and go further entering

kernel=vmlinuz-3.10-3-rpi
initramfs initrd.img-3.10-3-rpi followkernel

to /boot/config.txt, my Pi2 doesn´t boot anymore. 😥
Can anyone help me on this?

Help with installing on Arch ARM

Hi, I'm trying to install this driver first using pkms (following the guide on the readme page), then using make (following this guide), however I keep getting the following error:

Compile warning in ioctl_linux.c:8887:67: warning: iteration 16u invokes undefined behavior

I compiled the driver on arch linux raspberry pi. It compiles but issues various warning messages. It seems to work well, even at 5G connecting to my router at 434Mbps and achieving bandwidth (measured by iperf of > 200Mbps). The later version I received from Edimax rtl8811AU_linux_v4.3.7_11618.20141029 doesnt work at 5G and isnt set to use CFG80211 and doesnt even compile if it is switched on. So I decided to go with your (and others) work, which seems to be active.

The first compile warning is
os_dep/linux/ioctl_linux.c: In function ‘rtw_mp_efuse_get’:
os_dep/linux/ioctl_linux.c:8887:67: warning: iteration 16u invokes undefined behavior [-Waggressive-loop-optimizations]
sprintf(extra, "%s%02X ", extra, (pEfuseHal->fakeEfuseInitMap)[i+j]);
os_dep/linux/ioctl_linux.c:8875:3: note: containing loop
for (i = 0; i < EFUSE_MAP_SIZE; i += 16)

Because EFUSE_MAP_SIZE = 512 and array limit is EFUSE_MAX_MAP_LEN = 256 this looked wrong!

Array fakeEfuseInitMap[] has EFUSE_MAX_MAP_LEN elements. This is set in include/rtw_efuse.h. In your version v4.2.2_7502.20130517 this is set to 256 but in v4.3.7_11618.20141029 its set to 512

Changing removes warning message.

I am new to GIT and want to contribute and have created a pull request. Hope you can accept it, others will follow.

regards

Andy
