I'm seeing quite a few panics on the 3.14.x kernel series.
I'm using HEAD on kernel_version branch at the moment: 8727c18

Here are some of the panics:

I am using 3.17.2-1-ARCH with Antergos on my Lenovo 13 and experience connection drops with some wifi networks (wifi symbol says I am still connected).
Should i try to use the driver provided here or is this the same driver used in the kernel I am allready using?

I tested the connection with 2 wireless networks.
Network A seems to work fine. The speed is not as good as with windows but its stable.
However with Network B the connection drops every few minutes and only works again after turning the wifi off and on. I had the same issue with Ubuntu Gnome 13.10 (windows or other wireless modules have no issue with the network).
Using wicd instead of the networkmanager didn't solve the issue.
Any idea what else I could try?

I have a Linksys E-3000 running Toastman Tomato-USB firmware (http://toastmanfirmware.yolasite.com/) had it set on the 2.4GHz radio for 802.11G only. (Both B and N were disabled in that band.) My laptop was unable to see the network and attempts to join it as a hidden network also failed. I've had to either enable B and G or use the firmware's "N only" option. While the firmware says "N only" iwlist claims 802.11bgn. I'm not sure if the firmware's UI option is misleading or if there's a bug in how the driver is interpreting the capabilities of the network.

Additionally, the chip cannot see the 5GHz network I have enabled.

thanks a lot for the driver. Unfortunately I can not connect with it to an wpa2 encrypted network. AP is seen and authorization worked, but connection is not established (OS: Ubuntu 13.04)

Using Linux Mint 15 and I'm getting really slow download speeds.

I get about 30Mb download speeds on windows/vmware running linux mint 15. When booting to linux mint directly (using this driver) I get about 1Mb download speeds. The weird thing my upload speeds are normal, just the download speeds are bad. I've tried disabling ipv6 but still get about the same numbers.

Please let me know what I can provide.

I'm using the latest commit on the main branch, and I run 3.13.5-1-ARCH (64 bits). I try to connect with

sudo wifi-menu

I can see the networks, and sometimes I have the ! (existing active connexion) status, but when I try to connect, it doesn't get through. Here is the output of journalctl -xn:

When trying to switch to monitor mode in Ubuntu 12.04 Kernel 3.5.0-23-generic

user@Ubuntu-Usb:~$ sudo iwconfig wlan0 mode monitor
Error for wireless request "Set Mode" (8B06) :
SET failed on device wlan0 ; Invalid argument.

Any advice how to compile this under 3.10 kernel?
I can't seem to get it working on latest Archlinux Version

Currently, the rtl8723au driver reports to userspace to be a normal ethernet driver, rather than a wlan driver. This has various effects, for example udev's new interface naming code witll give the device an automatic name starting with "en" rather than "wl".

The 80211 core code uses this code to make sure the type is properly reported:

http://git.kernel.org/cgit/linux/kernel/git/torvalds/linux.git/tree/net/wireless/core.c#n735

The rtl823au driver appears to do its own 80211 stack, so it should add a thing and report things property.

Thanks for this wonderful driver. It works great with most wifi connections. However it generates kernal panic if I use the wifi hotspot device from FreedomPop. Is there a way I can generate a debug log to send to you? Thanks.

After a lot of testing I found an error in the upstream module for the rtl8723au device. The code from this repo is working fine...

The following error occurs when using the upstream module from Linux kernel 3.15.5 running an up to date Arch distribution. I know, that this message does not show a trace to the r8723au module but when using the code from this repository I can not reproduce this error. The error is reproducable by suspending the system and wakening it up again. On my system it always happens. After this error, it is not possible to connect to any wireless network anymore. When unloading the module and modprobing it, it mostly works fine again.

I have tried a lot of stuff like disabling other hardware, unloading everything not needed etc., but the only case this error occurs is when using the r8723au module from upstream.

Hopefully this report is helpful. If you need more information, please let me know.

I'm using this driver with the latest Ubuntu since 10 months. It works pretty well. However, when I perform a reboot from Windows 8 and load Ubuntu, the wifi speed is pretty slow. The workaround is to shutoff and restart the computer instead of a soft reboot.

I updated my xubuntu box kernel and after restarting i tried to re-install the driver i kept getting error 1-2. I read around that using "make clean" works but no luck.

Any help on getting this wifi stick going again would be glorious!

It works perfect on yoga i7 ubuntu 13.04, using:

• Android phone to share internet connection via USB
• sudo apt-get install git
• git clone git://github.com/lwfinger/rtl8723au.git
• cd rtl8723au/
• make
• sudo make install

(Just wanted to say thanks!)

With 3.15.3-200.fc20.x86_64 & 3.15.4-200.fc20.x86_64 comes the r8723au.

I thought it's the same as 8723au, which work very well 👍

But with r8723au it just show a connection, but nothing happens:

But it don't show up as interface with ifconfig

Device: lenovo yoga 13 with Fedora 19 and kernel 3.10.7-200.fc19.x86_64

I am currently having problems with my wireless device (with its own microprocessor) installed with 8723au module.

• rtl8723au module: 8723au with 2.4Ghz
• rtl8723au driver: Version as of Dec.16, 2013 commit
• Linux Kernel: v3.10.24
• File System: Ubuntu 13.04 (Raring Ringtail)
• hostapd driver: NOT the one via "apt-get install", got my wpa_supplicant_hostapd source codes packaged within the 8723au module supplier's driver v4.1.6_7336.20130426.

I cross-compile the driver (with my device's platform's compiler) using my Ubuntu 12.04 PC as host and across kernel v3.10.24 source codes - NO problems in compilation (make clean && make all),

I copy and install the created 8723au.ko in my device's file system, via "insmod 8723au.ko debug=4" - NO problems in installation.

For 8723au as Client or STA - NO problems in connection (connects fine, signal OK, link quality OK).

For 8723au as Access Point (without encryption) - NO problem in connection (connects fine, signal OK, link quality OK).

For 8723au as Access Point (with WPA2 encryption) - HAS problem in connection (Kernel panic).

Please check these files you might need as reference:

• https://gist.github.com/maggieroxas/9225765 - crash logs (when I run "wifiap start" which is just a script that runs hostapd in the background)
• https://gist.github.com/maggieroxas/9225791 - Hostapd configuration file
• https://gist.github.com/maggieroxas/9225777 - /var/log/messages of my device which contain rtl8723au logs

Some quick questions:

• I can see that this site offers the rtl8723au WiFi driver, and rtl8723au_bt for BT driver. How about hostapd driver? Is there and open source driver for this that works well with your rtl8723au/rtl8723au_bt?
  The default hostapd driver installed via "apt-get install hostapad" also crashes.
• This kernel crash happens only if the AP is set with encryption (tested only WPA2 so far), When there is no encryption, there are no problems at all.
  Does this give a clue?

I am currently having problems with my wireless device (with its own ARM microprocessor) installed with 8723au module, running in Client/STA mode.

I have the following setup:

• rtl8723au module: 8723au with 2.4Ghz
• rtl8723au driver: kernel_version branch as of Feb. 27, 2014 commit
• Linux Kernel: v3.13.5
• File System: Ubuntu 13.04 (Raring Ringtail)
• Platform: ARMv7

I cross-compiled the driver (with my device's platform's compiler) using my Ubuntu 12.04 PC as host and across kernel v3.13.5 source codes - NO problems in compilation (make clean && make all),

I copied rtl8723aufw_*.bin to my platform's file system, specifically at /lib/firmware/rtlwifi.

I copied and installed the created 8723au.ko in my platform's file system, via "insmod 8723au.ko debug=4" - NO problems in installation.

But I had problems for 8723au as Client or STA.

I can:

• Turn wlan0 up (via "ifconfig wlan0 up")
• Scan nearby Access Points (via "iw dev wlan0 scan")
• Set my wlan0's mode (via "iwconfig wlan0 mode managed")
• Connect to an unencrypted Access Point (via "iwconfig wlan0 snakecentral")

But I can NOT:

• Get IP from the Access Point I've connected to (via "dhclient -v wlan0"), because it times out.

ping to the router gets no packets back
ping over wifi to router works fine from Windows

Just checked the issue from Ubuntu 13.04 -- just the same

core/rtw_debug.c was removed, but the makefile still refers to it.

I noticed after an Ubuntu system update that my wireless device stopped working. So I looked thru some forums and remembered that I needed to reinstall the rtl8732au driver but after trying I'm getting the error:
modprobe: Fatal: Module 8732au not found.

I followed the steps exactly and the first install worked flawlessly a month ago on a fresh Ubuntu 14.04 install, but with the update I assume sth changed as the driver install now kicks up the error.

I'm still pretty much a noob, so I just throwing this out there for any troubleshooting advice on where to look for trouble and what to try for a fix.

thanks in advance!

Is it possible that the monitor mode not supporter is?

Hi, thanks for this driver!
I'm running Fedora19 now and, once installed missing packages, the divers compile and works perfectly.
Now i need to compile it under ArchLinux, but i get this error:

make ARCH=x86_64 CROSS_COMPILE= -C /lib/modules/3.9.5-301.fc19.x86_64/build M=/home/wifi/rtl8723au-master modules

Makefile:516: recipe for target 'modules' failed
make: *** [modules] Error 2

Why is it looking for 3.9.5-301.fc19.x86_64? I'm chroot-ing from Fedora to the newborn arch, but i don't think that's the problem...
Sorry for noob question, but i really can't find anything on the web.

I cloned the repo and ran the commands, but when I perform the modprobe I get the following message:

$ sudo modprobe 8723au
modprobe: ERROR: could not insert '8723au': Required key not available

Restart also does not present me a discovered wifi device.

$ uname -r

Driver version 4.1.6

I am using the Lenovo Yoga 14 ultrabook with this driver. For a while I've been using Debian testing/unstable with the driver from the master branch and have had no issues come up. However, recently I upgraded to kernel version 3.16, and since that version includes the driver already, I had to use that one.

Here's where some issues come up. When using kernel 3.16, I notice the wifi signal just drops randomly, but not while it is actually downloading/uploading data, only if it has gone idle for a few moments at least. When this happens, it seems the only way to get wifi back is to turn the wireless off and back on.

The issue with the system lock ups are very peculiar. Sometimes it just happens immediately after logging in, and other times, it happens seveal minutes later. I am mostly certain that the lockups are caused by the wifi, since it does not happen when I turn wireless off.

I also tried installing other distros with kernel 3.16, notably Ubuntu 14.10 and Arch. Both have the same issues described. I went back to Debian and installed kernel 3.14 and compiled the driver in the master branch, and none of these issues are present.

Under Ubuntu 13.10 (at least), the 8723au module won't auto-build correctly with new kernels. The error can be seen explicitly with dkms status, which gives:
dkms.conf: Error! No 'BUILT_MODULE_NAME' directive

I am not sure how BUILT_MODULE_NAME is distinct from BUILD_MODULE_NAME (the manpage for v2.0.20 seems to refer to them interchangeably!), but adding this extra line to dkms.conf resolves the issue.

Referencing a comment I made on an earlier thread: my RTL8723AU card in my Lenovo Yoga experiences intermittent network communication when connected to a WPA2 Enterprise network. Every minute or so, network traffic stops for around 10-15 seconds, while Network Manager shows the connection still active. The network in question uses PEAP for authentication with MSCHAPv2 for inner auth.

The laptop is running Kubuntu 12.10 64-bit Linux Kernel 3.8.8 (although this happens with the stock 3.5.0 kernel as well). The driver was built from source from this repository.

In the example above, it looks like my traffic degraded starting at 08:56:05 and then resumed shortly after 08:56:20.

Would anyone object if the code were limited to kernels 3.0 or newer? Is anyone using a 2.6.39 or older version?

Nearest I can tell, the merge from issue 11 wasn't correct.

The Makefile (as committed) shows the following on line 532:
CONFIG_REL8723AS-VAU := m

It should be as follows:
CONFIG_RTL8723AS-VAU := m

The difference? REL != RTL

Not sure if I should have opened a new issue, this is with WPA personal not enterprise. I can't get a large download (100megs) to succeed before it times out. It wouldn't connect to anything for a while and then it comes back. Is there anything I can do?

Here's the dmesg output, there's probably a lot of noise in here, sorry, not sure what you'd want to see. Thanks in advance for looking at this/all the work thats gone into this. It's appreciated.

Since the update to 3.15 stable yesterday, the driver isn't working well anymore. The issues are:

1 2 out of 4 bars max whereas on 3.14 it's 4 bars.
2 Frequent dropouts (e.g. connection loss).
3 Even on moments w/o dropouts it's very, very slow.

I had to downgrade to 3.14 and on 3.14 the driver still works perfectly, max bars, no dropouts, fast connection, etc.

Hopefully you can fix the driver for 3.15 :)

i have been unable to install this driver on any of four versions of fedora i have tried it on now, each were fresh install and each had been updated. in every case, this is/was the error i have received:

make

make: *** /lib/modules/3.11.10-301.fc20.x86_64/build: No such file or directory. Stop.
make: *** [modules] Error 2

this is not the best part of owning a lenovo yoga.. and probably not the worst. Hopefully this is some stupid mistake on my part but googl seems to indicate that other people have struggled with this... possibly without success.

In any case, I have used your product many other time, so i thank you.

Cheers

This driver works quite well for me on a Lenovo Yoga 13 laptop with kernel 3.13.0.

However there is a single restaurant in town that has an access point that causes the driver to throw errors and not associate with the access point. The dmesg output is:

I'm compiling and using linux 3.13.0 from the git repo and I get this every so often:

http://pastebin.com/VcFPd4Yt

Hello there, I'm not a very experienced Linux user, so sorry in advance for stupid questions/assumptions/lack of technical information.

The issue is the following: in one particular spot of a university library my Arch system gives me a kernel panic. Sometimes it happens upon connection establishing, sometimes a bit later, but always around that time.

I'm pretty sure it has something to do with wireless; I tried to disable wireless in NetworkManager and the problem did not occur for ~30 minutes I was on the spot. Again, with wireless on it happened almost instantly after connection had been established.
Also for some reason this issue occurs only in one spot, probably with specific wireless router. Unfortunately, I don't have access to it and it seems to be hidden.

My machine is Lenovo Youga 13 with Arch Linux.
uname -r gives me:
3.13.6-1-ARCH

Please tell me if there is any other information I could provide.
Thank you.

Hey, thanks for writing this driver. Awesome job!

Unfortunately I seem to have trouble getting any real throughput using this driver. I tried transferring some files in my local wireless using sftp, and all transfers never seem to exceed 196kb/s on Arch. On windows the chip has no trouble transferring data at rates above 5mb/s between the same set of devices; and even an external 8192cu usb stick manages to get up to 4mb/s.

The issue persists even when compiling the module without power management support . Any ideas on what might cause those very slow transfer rates? Sometimes it seems like it jumps up to 360kb/s, then the next second it slows down to less than 100kb/s ..

First, thanks for doing this..

Until this driver gets into the kernel, I'm trying to set up DKMS with it for my wife's new yoga 11s laptop. She's a compulsory upgrader, so dkms support is a must... although i guess an rc.local hack might also work.

Regardless, it appears my simple dkms.conf file doesn't work:

PACKAGE_NAME="8723au"
PACKAGE_VERSION="0.1"
BUILD_MODULE_NAME[0]="8723au"
DEST_MODULE_LOCATION[0]="/kernel/drivers/net/wireless"
AUTOINSTALL="yes"

However, when i run dkms build i get this:

$ sudo dkms build -m 8723au -v 0.1

Kernel preparation unnecessary for this kernel.  Skipping...

Building module:
cleaning build area....
make KERNELRELEASE=3.11.0-12-generic -C /lib/modules/3.11.0-12-generic/build M=/var/lib/dkms/8723au/0.1/build....

Consult the make.log in the build directory
/var/lib/dkms/8723au/0.1/build/ for more information.

and the log shows:

.. its almost like its trying to build the 'module' as a built-in, instead of a module? I checked the Makefile and its waaay more complicated than most module makefiles.

Any idea how I can get it to work?

Hi,

I'm trying to install the rtl8723au driver on a Lenovo Yoga 11s running current stable version of Debian (7.3 "wheezy"). I download the files using git as advised, but when running make in the rtl8723au directory, I get an error as show in the extract below. I have tried to ensure I have the relevant packages installed - e.g. linux-headers, gcc, etc.

I'd be very grateful for any advice on what the problem could be (I'm still fairly new to Linux!). Many thanks for making this driver available.

Sam

I am really at a loss for understanding this, but with the latest commit to the kernel_version branch 60e49d3 I am no longer able to connect to any networks and trying to connect to the wireless router in my home causes the router to disconnect all devices on the network and no other devices can connect to it until I stop trying to connect with my laptop which uses the rtl8723au driver. As before in #25 , I have a yoga 13.

In between "BOGUS urb" tracebacks as discussed in issue #25, this[1] pops up.

EDIT: Even more dmesg output [2]

[1] http://pastebin.com/6xATwxqs
[2] http://pastebin.com/DNnTxcSD

This works great! There's a couple of warnings during make:

Despite these warnings, it compiles fine and installs and works correct.

Also, a simple install script that would be handy to be part of the repository:

#!/bin/bash
make clean
make
sudo make install

sudo modprobe 8723au

   wlan0: Driver does not support AP mode

How to solve?

Been having frequent kernel panics with the latest commit of the driver (d30225b) and the latest arch kernel 3.13.6. I'm on a lenovo yoga 11s.

It can occur as soon as I log on or I get as long as 15 minutes , but it happens every time. I still have testing to do but I updated the arch kernel and with that got the latest commit of the driver. I still need to revert the driver to the last commit and also the precious arch kernel, for testing, but I wanted to bring it up as an issue with arch kernel 3.13.6 and commit d30225b.

I will try to get a kernel dump message next time it happens.
