rtl8723bu's Issues

Compiling on Arch fails

I tried to build this on Arch Linux.

uname -r
4.2.5-1-ARCH

But when I do make I get this output:

make ARCH=x86_64 CROSS_COMPILE= -C /lib/modules/4.2.5-1-ARCH/build M=/mnt/data/Documents/Source/Kernel module test/rtl8723bu-master modules
make[1]: Entering directory '/usr/lib/modules/4.2.5-1-ARCH/build'
Makefile:659: Cannot use CONFIG_CC_STACKPROTECTOR_STRONG: -fstack-protector-strong not supported by compiler
make[1]: *** No rule to make target 'module'. Stop.
make[1]: Leaving directory '/usr/lib/modules/4.2.5-1-ARCH/build'
Makefile:355: recipe for target 'modules' failed
make: *** [modules] Error 2

I admit I am not an expert on compiling kernel modules, this is actually the first time I have to do this.
So I apologize if I am missing something obvious here but after googling and trying different things for a few hours I am still clueless to what is going wrong here.

I do have base-devel as well as the linux-headers installed.
The strange thing is that I tried compiling it on my main computer while setting up my laptop (which needs this module) and somehow I got it to work.
During the laptop install I noticed that it installed a newer kernel than the one I compiled with on my main PC so I updated that PC. Later all attempts to compile it failed and the update seems to be the only thing that changed.
Thanks for any potential clues on how to solve this.

Bluetooth scan issue

We are using LM811 Wifi and Bluetooth module with rtl8723au_bt-troy and rtl8723bu drivers. Using just Bluetooth functionality we are able to scan only the nearest devices. For Bluetooth scan to work properly it is also neceary to set up wlan. Then current consumption rises and the number of scanned devices is higher.
Is there a way for increasing Bluetooth scan power without using wifi driver and wlan?

I installed kali 2016.2 on the Cube i9, and I have updated it, upgraded it, and I have made sure that linux headers are installed. But every time I try to "make", the console spits out the error specified below, the folder that is missing is /build, the rest is there. If I manually create the folder it does not work either. Please let me know if you know how to correct that issue.

rtl8723bu blocking interrupts for long time?

We are currently using the rtl8723bu in a small embedded project and the device driver seems to work nicely, thanks!

It however seems like the driver is blocking interrupts for a somewhat lengthy time thus starving the rest of the system trying to execute. We experience serial port overruns etc even when the system otherwise have no noticeable load. If we pick down the wlan interface everything works.

My question here is if it could be possible to identify the path that blocks the interrupts and hopefully try to make it a bit more finegrained?

Chance of getting put in mainline?

Is there any chance that this will eventually be incorporated into the main Linux kernel, or is there something preventing it?

Connect RTL8723bu wifi + bluetooth dongle driver to Intel Galileo

Hi,
I am trying to setup wifi capability on Galileo. I am using EDIMAX EW-7611ULB dongle. I am using 3.8.7 Yocto. Upon submitting the make command, I get the following error.

I appreciate your help.

Thanks,

implicit declaration of function ‘autosuspend_enter’ when compiling on BeagleBoneBlack

Hi,

When I try to compile this on a BBB, I get the following error:

It looks like the function autosuspend_enter is defined in os_dep/usb_intf.c, but I can't find it's declaration. I pulled the most recent code today.

Thanks for any help you can give.

Wi-Fi promiscuous mode

Hello,

I would like to get all packets from the Wi-Fi interface with a RT8723BU dongle.
I'm able to create a virtual interface in monitor mode with this command:
iw phy phy0 interface add moni0 type monitor

Then, I'm launching a python script that uses libpcap to capture all Wi-Fi packet and not only packet with my MAC address. But, I'm not able to get those packets from this interface. Do you know if this driver is able to receive those packets?

Thanks for your help,

Arthur

Freezes...

I have a Laptop and use the driver from here... Sometimes (2-3 per day) the laptop freezes completely. magic SysRq key doesn't do anything. memtest works fine...

So the question is: Are the freezes related to the WiFi driver from here?!?

How can i figure out this? Any ideas?

Low Bluetooth signal strength with wifi down

Hello, and thank you very much for your work.
We are using the rtl8723bu driver and rtl8723au_bt driver on a rtl8723bu usb dongle. It works perfectly with some minor issue that we were able to workaround.
The big problem we're experiencing now (that was mentioned in the issue #2) is that if the wifi adapter isn't upped at least once, the bt transmit level is very low.
Our device (based on freescale ix6 arm) is booted with wifi driver loaded but adapter down. Our application is advertising through btle. If we test with LightBlue, an iOS app that displays the signal strength, we can see a signal level of about -90dbm at 1.5m from the dongle. When we up the adapter (ifup wlan0), the signal immediately raises to -60dbm.
if we down the adapter, the signals is still to pretty good levels (-60dbm).
Notice that we had an issue with the IPS, we removed the CONFIG_IPS flags because when the driver entered the power save mode, we were unable to communicate reliably with the driver again.
The USB ids are: 0bda:b720. kernel is 4.2.0

Thank you and best regards

Federico Fuga

RTL8723BU BT driver

Thank you very much for this driver. But is there any known Bluetooth driver for RTL8723BU in existence?

Driver will not load automatically and ifconfig shows no wlan0

I just got a new WiFi/BT adapter. Trying to use it on my RP2. The adapter is using rtl8723bu chip; therefore, I am hoping this driver will work.

I have no problem to compile and install the driver. Once restarted, the 8723bu.ko will not load automatically and I have to run insmod 8723bu.ko command in order for it to load. After that, command ifconfig will show no wlan interface.

lsusb shows the following ID.
ID 7392:a611 Edimax Technology Co., Ltd

Is it the ID that is causing the problem? My RP2 is running Raspbian kernel v4.4.21-v7+, which is the latest. Any help would be appreciated!

Regards,
lkw

Drivers restart in loop

Hi,

The driver constantly restarts in loop when I'm trying to connect to an AP with wpa_supplicant.conf.

The command I typed is:

wpa_supplicant -iwlan0 -c /etc/wpa_supplicant.conf

I put the dmesg output below, do you have any idea where this problem should come from?

thanks for your help

Wifi bandwith drops when Bluetooth is used to stream sound in A2DP

Dear lwfinger,

I have a question about the Wifi/BT coexistence performance.

My use case: Stream a song from a music streaming service by Wifi and play it on a Bluetooth speaker

I used iperf to check the Wifi bandwith:

When there is no sound streamed to the Bluetooth speaker: 1,5 Mbit/s
When there is sound streamed to the Bluetooth speaker: 300kbit/s

Is there anything possible to optimize that?

Thanks for your help

Can't scan wifi networks

sudo iwlist scan
wlp0s20u3i2  No scan results

I can't scan wifi networks, but

nmcli con up id my-wifi

work good with prewiously added profile for my network.

P.S. I try to disable/enable -DCONFIG_CONCURRENT_MODE, but scan don't work.

commenting out concurrent mode breaks build.

backtrace dump when joining WPA with rtl8723bu

Hello Larry
I think the work you have done to supply the ported driver is fantastic but I am having some issues when joining a WPA network.
My system is using a 3.14.47 kernel configured to give all the appropriate drivers to support the rtl8723bu. I have built the driver and it brings up the card beautifully and I can scan, detect without problems. Connecting to an unprotected network is working well but when connecting to a protected network there is a stack dump

[ 52.901089] ---[ end trace b49df6b01bd39533 ]---

The issue seems to be around the area of bss in sme.c in the kernel
if (WARN_ON(!bss))
return;

And I think it may be linked to a warning that is generated when compiling the rtl8723bu driver
/board-support/rtl8723bu-master/os_dep/ioctl_linux.c: In function translate_scan:
/board-support/rtl8723bu-master/os_dep/ioctl_linux.c:798:1: warning: the frame size of 1160 bytes is larger than 1024 bytes [-Wframe-larger-than=]

That function is relying on the stack to return the bss structure instead of allocating memory and returning the pointer.

Has this issue been seen on any of the other drivers, maybe the pci version ?

Any help to track this issue down is appreciated.

Once the backtrace has happened I am connected and can obtain an ip address, and I can see the mac is registered on the access point so there is network just the "knowledge" of the SSID and connection is lost due to the error.

Kind Regards
Marc

rtl8723bu in odroidxu3

Hi,
I try to install driver in odroid xu3 and i got these error message

Makefile Typo?

Hi, I just tried to build and install the driver, but it failed at the "make install" step.
The error message claimed "no such file or directory" and when taking a closer look I noticed there was a dot in the filepath where there (I assume) shouldn't be a dot.
I changed the Makefile and now everything went fine.

The line in the Makefile reads:
cp -f rtl8723b_fw.bin $(FW_DIR)./rtl8723b_fw.bin
This was added in commit da63138 just recently.
I changed the line in my Makefile to:
cp -f rtl8723b_fw.bin $(FW_DIR)/rtl8723b_fw.bin

Am I right to assume this was a typo or is the error somewhere else on my end?

我的wifi搜不到网络

没装这个驱动搜不到网络。装了之后还是不行。我用的是gnome。网卡是rtl8723b.
My wifi device still can't find networks.The hardwareID is B720.
Please,help me.

Cannot install in Lubuntu

In Ubuntu I was able to install the driver. However, I chosed to install Lubuntu for resource reason.

Can't unplug the wireless adaptor

Hello,

Thank you for developing and maintaining the driver of the USB wireless adaptor.

I tried my wireless adaptor with raspberry pi 2b (Ubuntu 16.10 armhf installed)
And of course, I can use it as AP and connect other wireless network.

But I found it's strange after I un-pluged it. I can still see the interface from ifconfig.

And I tried my wireless adaptor with my PC (Ubuntu 16.04 amd64 installed) And I can
reproduce this problem too.

I use the newest code to compile the driver module,

And here is my other information:

Hello, It's me again.

Thanks again for your programming the device driver.

I got another problem here.

I compiled the driver from the newest source code, and I found two interface:

I checkouted bc9e782 , recompiled the driver and had no this issue. Did a bug introduced by recent commit(s)??

I don't know why, maybe my usb wifi adaptor's problems ?

It's late now, I will add more information after I'm free.

Am I the only person run into this situation?

Association never completes

Hello,
I've build the driver for ARM6 (RasberryPi B) using kernel version 4.4.8. The driver builds and I can install with modprobe -v 8732bu. A wlan0 interface is created after the driver loads.
I want to use the wlan0 in STATION mode and when I run wpa_supplicant I get the follow message in /var/log/messages

........ followed by repetitions of the above lines.....

The output shows 'start assoc' but the association it ever completes and consequently the wlan0 interface is never brought up.
Is there anything that I can do to overcome this problem? i.e. is there a driver parameter that I can set when 'modprobe-ing' the driver?

Thanks

It's not possbile to connect to my WPA2 AP after Commit 7442c9e6ee8a4b810ceb936eb8340f2a508d0262

Hi,

after commit 7442c9e it's not possible to connect to my WPA2 AP anymore. I found the bad commit with git bisect.

with kind regards

Compilation not supported on GCC6

At least that's what this is caused by, as far as I'm aware.

from /root/build/rtl8723bu/core/rtw_cmd.c:22: include/linux/compiler-gcc.h:106:30: fatal error: linux/compiler-gcc6.h: No such file or directory #include gcc_header(__GNUC__) ^ compilation terminated. scripts/Makefile.build:308: recipe for target '/root/build/rtl8723bu/core/rtw_cmd.o' failed

Arch Linux ARM now uses GCC6 which means this module now unfortunately cannot be compiled on that platform.

Driver not loaded on Kernel 4.8.0.32

Driver does not load on Kernel 4.8.0.32.
But it loads after resuming from suspend.

Tested on Linux Mint, Kubuntu and Ubuntu.

porting to Mac OS X

sorry if this wrong place to ask but can you help me to port these codes for mac to get the drivers ready for mac os x

Need a way to determine antenna port when using single antenna

We have used the RTL8723BU on our board and have had some complaints about the transmit power of the module.
The driver is built as is from the lwfinger/rtl8723bu repository and all seems OK when in close proximity to the board.
Our system uses only a single antenna for the WiFi and BT.

We would like to know how to select the desired antenna as it seems like the default one being used is not RF0. We think the default mode is with antenna diversity.

Is there a way to actively select the antenna and to force it to single antenna mode ?

Thanks
Marc

this driver is ok for android 6.0.1? after porting this driver to android 6.0, wifi usually enter into limit mode after get IP

how to build on beagle bone black

Hi,

I'm trying to build this on a BBB. I have cloned the repo, but trying to make it gives me an error:

root@beaglebone:~#git clone https://github.com/lwfinger/rtl8723bu.git
root@beaglebone:~#cd rtl8723bu
root@beaglebone:~/rtl8723bu# make
make ARCH=armv7l CROSS_COMPILE= -C /lib/modules/3.14.46-ti-r70/build M=/root/rtl8723bu modules
make[1]: Entering directory `/lib/modules/3.14.46-ti-r70/build'

make[1]: Leaving directory `/lib/modules/3.14.46-ti-r70/build'
make: *** [modules] Error 2

What is the proper way to build this?

Setting up a WIFI AP via hostapd

Has anyone been successful with using this RTL8723bu driver to setup a WIFI access point via hostapd?

I can see the network from my client device, but every time it tries to connect, it fails with the following line in dmesg:

RTL871X: ap recv disassoc reason code(8)

This is the same no matter what client I use (Android phone, Windows PC, etc.)

This reason code maps to "Disassociated because sending station is leaving (or has left) BSS". Which doesn't make sense in this context as the phone is stationary with a strong signal. The module works fine as a WIFI client, just not as an AP.

At this point I'm not sure if it's an issue with the driver, hostapd, or some configuration setting somewhere.

Hostapd is using driver=rtl871xdrv

Compile errorn on kernel 4.3.4

Hi there,

recently I have updated my fedora 22 to kernel 4.3.4.200 now the driver could not be compiled with the following errors. Could You make a patch please.

Thanks in adwance:

Connecting works after several attempts when IPv6 is enabled

Using this driver I have to make connection attempts several times before it finally work. I tested this over a few weeks and it was clearly not a fluke. It happens with various routers, not just a specific one. Tested both on linux 4.3 and linux 4.5 and same thing happens.

multiple rtl8723bu units at once - second unit will not work

If I run multiple rtl8723bu (odba:b720) realtek units at once, only one of the units will work. From what I can tell, it's consistently the the last one loaded (i.e. wlan3 vs wlan2), so order matters.

I have 3 RTL8723BU USB units, and tried plugging random pairs of them in at once to ensure it wasn't the actual device, or the usb port itself.

Seems only to be related to the order they are picked up by the OS.

Building the driver

$ sudo apt-get install build-essential git
$ git clone https://github.com/lwfinger/rtl8723bu.git
$ cd rtl8723bu
$ make
$ sudo make install
# load the module (which will be loaded automatically until the next kernel update)
$ sudo modprobe -v 8723bu

OS details (happens with kernel 3 and 4)

I'm using these units specifically:
http://www.ccandc.com.tw/products_2.php?prod=269

Further context

I tried configuring each as a normal wifi card and only the second one would work.

Similarly, configuring it with hostapd (creating an access point), only the second one would create an access point. That is, if i configure hostapd.conf to use wlan3, it works. If i configure hostapd.conf to use wlan2, it doesn't work.

However, the same scenarios work fine with the RTL8188CUS usb wifi adapters that i have plugged into my device. Thus, I believe it's a driver problem, rather than a kernel/OS problem.

error compiling with CONFIG_CONCURRENT_MODE enabled

Hi,

When compiling with the CONFIG_CONCURRENT_MODE define enabled in autoconf.h, I get an error during compilation. See below.

My goal is to work in concurrent mode (AP+STA). And I am following this nice post:
http://randomstuffidosometimes.blogspot.nl/2016/03/rtl8192cu-and-rtl8188cus-in-station-and.html

any ideas?

best, Matthijs

stuck while rebooting when driver is loaded?

Hi,

with the rtl8723bu driver loaded, my device won't reboot anymore. Its 100% reproducible. And solved by booting without loading the driver.

system log output is:

the used device is a beaglebone enhanced from Sancloud, running our own image called Venus. So not the IoT beaglebone image. I am still awaiting feedback to know if this same issue happens on their beaglebone IoT image, as I know they use this same driver.

Any ideas? Is this a known issue?

Matthijs

ps. I have this issue (also) when not working with the concurrent_mode. About which I made that other issue for last night, #35. So thought it best to keep these two issues seperate. Also I have some more compile errors with the concurrent_mode. And fixes for them this time ;-). I'll post that in #35, after doing some more tests.

It is on a TI AM3352 using a LM811 USB IC.
I have looked at the line of the code raising the error, and understanding the potential cause is beyond me at this point in time.

Are you able to suggest a potential starting point of investigation?

kernel deadlock warning during driver load

Hi Larry,

see message at 24.146556 below. It doesn't seem to do any harm, at least, I did not find anything that doesn't work yet.

Any thoughts on below? Or should I perhaps go to connman with this?

best, Matthijs

Two wifi adapters shown in network manager even if I have only one. Internet disconnects randomly

My computer has only one wifi card (inbuilt in the laptop). But, I am seeing two entries as shown in the above screenshot. Internet works only with one of the devices decided at random. So, often I choose one device, check internet and choose the other when internet does not work.

machine locks up when setting up an ad-hoc access point in linux-4.4.0

When I set up an ad-hoc access point using wicd on slackware64-current (x64, kernel linux-4.4.0) the machine locks up completely.
what info can I provide to debug this issue?
