lwfinger/rtl8188eu

Repository for stand-alone RTL8188EU driver.

IMPORTANT - PLEASE READ:

Beginning on November 4, 2019, I will NO LONGER support people that have downloaded the source as a zip file. Using git has much more flexibility. In addition, there is much less likelihood that a user will contact me with a problem that is ALREADY fixed.

If your system says that /lib/modules/...../build does not exist, you have not installed the kernel headers, you have done it incorrectly, or you are not running the kernel for which the headers have been installed. The necessary steps are dependent on which distro you are using. Creating a new issue and asking at GitHub will not be productive.

Your kernel configuration MUST have CONFIG_WIRELESS_EXT set.

Unsolicited E-mail sent to my private address will be ignored!!

If a build fails that previously worked, perform a 'git pull' and retry before reporting a problem. As noted, if you had downloaded the source in zip form, then you would need to get an entirely new source file. That is why using git, which downloads only the changed lines, is required.

Frequently asked Questions

The network manager says: "Device is not ready"!

Make sure you copied the firmware (rtl8188eufw.bin) to /lib/firmware/rtlwifi/

NetworkManager does not list SSID

NetworkManager changes the Wi-Fi MAC address during scanning to improve privacy but this adapter does not support it. To address this issue, please create /etc/NetworkManager/conf.d/80-wifi.conf with content:

[device]
wifi.scan-rand-mac-address=no

and run systemctl restart NetworkManager

Error inserting 8188eu

Module is correctly compiled, but when I execute modprobe 8188eu command I receive the following error message:

Error inserting 8188eu (/lib/modules/3.8.0-29-generic/kernel/net/wireless/8188eu.ko): Unknown symbol in module, or unknown parameter (see dmesg)

I'm trying to install this driver on Ubuntu 12.04 with kernel revision 3.8.0.29.

Do you know the cause of this error?

Thank you

Issue #3 reintroduced on in-kernel driver

Hi,

it seems that the same problem reported in #3 was reintroduced on the in-kernel version of this driver.

I had to build 3695d58 manually to get hostapd working.

The error is exactly the same of #3, then I'm not attaching any logs, just asking you to check if that fix made it way to the mainline kernel.

Poor link quality and constant disassociations

This is more of a mailing list question. I would like some help debugging an issue with the 8188eu driver being used on an Ubuntu 13.10 x64 running the 3.11.0-12 kernel. I have the driver compiled (after applying patch located in another issue) and installed. I'm using wpa_supplicant to connect to an AP using WPA2. The connection seems to work but it will immediately disconnect. Here's a sampling of wpa_cli output:

Signal strength seems to fluctuate between -74dBm and -50dBm but link quality tends to be always very low. Granted, with constant disconnections I'm not sure that link quality is an accurate measure. Do I need a driver parameter? Is this a voltage problem with USB? Or a misconfiguration of wpa_supplicant?

TP-Link TL-WN725N not working on latest Ubuntu

Hi,

I looked through the current issues, but none of them described my issue.

I am using Ubuntu 13.10 3.11.0-13-generic kernel.

The latest commit of your driver I used is f4d1258.

After pulling the latest master branch and compiling your driver it stopped working. The network manager says: "Device is not ready". I see it in the usb devices list, but cannot get it work. I reverted to the mentioned commit for now, but I don't know what the next step is.

Unusable after upgrading to Fedora 19

I had fedora 16 (3.6.11 kernel) and my TP-Link wireless usb used to work fine with the old repo of 8188eu driver (where I had to download firm and linux separately). Recently I upgraded my desktop to use fedora 19 and I downloaded 8188eu driver from this repo as the old one was not working with fedora 19 kernel (couldn't find daemonize and I think thread_start on insmod).

Now on fedora 19 (3.11.9), I get a bad connection with the usb wireless. Whenever I reset the connection, it works for 3/4 seconds and then just stops. You can see the dmesg output below. If you need some more info please let me know. How can I fix this issue?

losing wireless connection every 10 mins

Hello,

I am losing the wireless network connection every 10 minutes. I cannot ping even the default gateway.

Please let me know if I can provide any more information.

I did not see any information pertaining to this issue in syslog with "debug = 4". With debug = 5, there was way a lot of information. I am not sure how much of it is relevant, hence I am not attaching it. Please let me know if you need it.

~~~ MAC IOL_exec_cmds Failed !!!

I am working with Fedora 12, kernel version 2.6.32.26-175. In order to use some legacy code that only works with this old kernel, I had to install TL-WN725N v2 on my old linux desktop. I can compile and install the driver. But seems like it did not work. dmesg shows error like "~~~ MAC IOL_exec_cmds Failed !!!". I am wondering if this kernel version is supported or if I did anything wrong. It worked fine on Windows. Thanks. Below are some more information:

Hi,

I know that this is not an issue. But... is possible add to repo a readme for compile and install this driver? I don't have experience for this!

Thank you!

Can not build a Soft-AP using hostapd

Try to build a Soft-AP with rtl8188eu, but it failed.
My steps:

• git clone https://github.com/lwfinger/rtl8188eu.git
• cd rtl8188eu && make && make install
• insmod 8188eu.ko
• ifconfig wlan0 up
• hostapd hostapd.conf

An AP is built now and I can find the AP with my mobile device.
But I can not access this AP after I typed right password. The hostapd reported:

+rtl871x_get_sta_wpaie, 18:e7:f4:93:f2:b3 is sta's address
wlan0: STA 18:e7:f4:93:f2:b3 IEEE 802.11: associated

wlan0: STA 18:e7:f4:93:f2:b3 IEEE 802.11: disassociated

Looks like my password is wrong, but that's not the case.
I set driver=rtl871xdrv in hostapd.conf (set driver=nl80211 hostapd can not start).
My environment is Ubuntu 12.04 with i386 PC, the commit version I used to build the module is 993b021.

(SOLVED)Unable to create hotspot

Hi everyone,
First, thanks for this driver that makes my FW150US usb device work great as wifi adapter. But I am afraid i have not been able to create yet a hotspot. I am quite newbie with linux and maybe this may seem quite basic but I have been trying for a couple of days without success. I use Linux Mint 13 Mate. I have tried directly with the "Create New Wifi Network" option and later I have been reading some manuals about hostapd but have not been able to make it work. I have seen that your file has an special hostpad.conf. Would it be possible that anyone told me which exact manual should I follow in order to make it work? (a very basic step by step one would be great). I have tried to do it by myself reading, from the internet, but I have met different methods and now I am quite confused. I can make a fresh install again if necessary (I have installed so many things so far, trying to make it work...). I would really like to create my access point with linux, as right now, every time I want to connect my phone and laptop to my computer I have to restart it and load windows, where I can create a hotspot... : (
Thank you very much in advance.

It compiles well on CentOS-6.4 but causes system panic

After compling the driver and installing with sudo make install, I insert the module using sudo modprobe 8188eu and the system stops responding and restarts automatically. But it repeats the restarting until I unplug my wireless card (TP Link 725n).

BTW. It works great in ubuntu 12.04 :)
Thank you.

I'm uploaded the latest rtl8188eu driver from realtek, please check it.

It included driver, documents, wireless_tools, etc.

I686 and x86_64

Hello :)
First of all thanks for maintaining the driver.

I have tried the driver in:
Ubuntu 12.04 i686(kernel 3.2),
Linux mint 13 x86_64 (kernel 3.2)
Ubuntu 13.10 i686 (kernel 3.11)
Ubuntu 13.10 x86_64 (kernel 3.11).

The old driver version(1.4mb) doesn't compile in Ubuntu 13.10 x86_64, the last version(700kb) compiles in Ubuntu 13.10 x86_64 but it doesn't work.

The old driver (1.4mb) works fine for ubuntus i686 ( kernel 3.2 and 3.11) the last driver version compiles but doesn't work.

In mint 13 x86_64 doesn't work any version driver

It's this correct XD? you have the same experience or i'm doing something wrong?

The procedure that i follow is:

$ make
manually send modules rtl8192cu, rtl8192c_common, rtlwifi to the blacklist in /etc/modprobe.d/blacklist.conf
$ sudo make install
$modprobe 8188eu

device info:
Bus 001 Device 003: ID 0bda:8179 Realtek Semiconductor Corp.
TL-WN723N

Compile error.

Hi,

I have download the linux-header and linux-tools. I have clone this code and then I have write "sudo make" but I have this error:

make ARCH=arm CROSS_COMPILE= -C /lib/modules/3.6.11+/build M=/home/pi/rtl8188eu modules
make: *** /lib/modules/3.6.11+/build: No such file or directory. Stop.
make: *** [modules] Error 2

I have 3.6.11+ linux kernel.

Any suggestion? Thank you!

Ethernet packets transmitted OK, but IP-related packets ignored

Hello,

I've compiled the current revision of the rtl8188eu.git driver against a 3.12.20 kernel (with no errors or warnings) and also cleanly compiled the current hostapd from Realtek. All in all, I managed to set up a WPA connection where the RTL8188EU device functioned as AP at the Ethernet level: With a sniffer, I verified that Ethernet packets go across, and the client was properly assigned an IP address with DHCP.

The problem is that the AP doesn't respond to ARP requests, even though the requested IP address is the one assigned to wlan0 with ifconfig. Neither does it respond to pings (as for how the client knew the AP's MAC address -- I used gratuitous ARP from the AP). The AP had no problem sending ARP requests, of course.

So the Wifi dongle (or its driver) behaves as if it was somehow detached from the IP protocol layer, or didn't know its IP address. I don't know what exactly.

The same problem was repeated exactly, with an RTL8192CU device, with the rtl8192cu-fixes.git repository, which is Realtek's driver + fixed to work with a recent kernel.

For more details, please look at my blog post on this:
http://billauer.co.il/blog/2014/06/linux-realtek-hostapd/

Any insights?

Thanks,
Eli

Unable to compile module after updating from 3.6.11+ to 3.10.18+

After updating my Raspberry Pi from Raspbian 3.6.11+ to 3.10.18+ using rpi-update yesterday I cannot now compile 8188eu.ko without getting warnings which appear to stop the kernel loading the driver.

If I compile using the following which required that I provided some input to fully configure .config during command make modules_prepare

cd src/linux
make mrproper
zcat /proc/config.gz > .config
make modules_prepare
cp /home/pi/src/firmware/extra/Module.symvers .
cd /home/pi/src/rtl8188eu-master
CONFIG_RTL8188EU=m make -C /home/pi/src/linux M=pwd

the compile terminates with the following warning

packets dropped on raspberry-pi

I've been using this driver with a raspberry pi (last firmware and kernel build #524 https://github.com/raspberrypi/firmware) and I haven't been able to use an open wifi, while iwconfig shows that I am connected, ifconfig shows all packages dropped.
What can I do to debug it more?
Hope it helps.

RTL8188: ERROR indicate disassoc

Hi,

I installed the driver with a TP-LINK TL-WN725N V2 (0bda:8179) on Centos 6.4 2.6.32-358.18.1.el6.i686.

Installation went fine but I saw in dmesg:
ADDRCONF(NETDEV_UP): wlan1: link is not ready
RTL8188: ERROR indicate disassoc

Am I missing something ?

Thanks !

TP-Link TL-WN725N V2 led not flashing

Hi,

I installed the driver, its working great except led is not flashing.
I found this thread: http://www.raspberrypi.org/phpBB3/viewtopic.php?p=342670

I tried to compile it with #define CONFIG_LED but no success.

Any thoughts on this?

Thank you !

hangs when booting from flash

I am using an embedded board, which can either boot from sdcard or nand.

I have successfully used the 8188eu driver (when booting from sdcard) with the TL-WN725N, both to connect to a network and as an AP.

however when booting from nand, the command 'ifconfig wlan0 up' just hangs for around 70 seconds give or take, then returns with 'SIOCSIFFLAGS: Operation not permitted'.

while 'ifconfig' hangs, if i ssh to the board, i get the message of the day, but no shell ( i finaly get the shell when 'ifconfig' returns)

nothing appears under dmesg while issuing the 'ifconfig up'

note that wpa_suppclient and hostapd also hangs in a similiar manner.

thanks,
edn1

Compilation into a kernel

Hi, I see in your repo description that this is the 'stand-alone RTL8188EU driver'. Pardon my ignorance, but does that mean that it cannot compiled into the kernel? I'm trying to build a kernel (https://github.com/linux4sam/linux-at91) for an embedded device, but when it gets to the this driver it fails.

Any tips would be greatly appeciated!

Invalid USB device ID

It appears as though one of the device ID's for the USB devices handled by rtl8188eu is incorrect.

Checking on the internet and reviewing other wifi drivers it appears the Abocom USB ID is wrong and the Vendor ID and Product ID have been swapped.

The following patch should provide the fix.

Insanely slow speeds and unstable connection - TP Link - TL-WN725N

I have ArchLinux-Arm on a BeagleBone Black.

I just installed this driver, and it will just not respond after 30seconds of getting connected to the router.

It gets an IP Address, and as soon as i SSH into it, it starts to have horrible network performance..

The BBB is powered by a 5V 2A cable and it is about 4feet away from the router and it won't hold a wireless connection using the TL-WN725N wifi dongle for more than 30seconds before it starts to timeout.

TP-Link WN725N: Dropping AP connection signal (from initial 100% to 20%) - power management issue?

Thanks for for all the work done with this driver so far!

Installed the driver on debian 7 / 3.2.0-4-686-pae and set up an encrypted connection to my AP with the network manager (WPA2/PSK). The initial connection strenght is 100% and i have access to the internet. Ping etc. works fine. As soon as i don't have any traffic on that connection (for ~1 minute), the connection signal will drop to 20% and i won't be able to generate any traffic again - ping won't find it's destination. If i reconnect to the AP it works (as long as i keep the connection 'busy'). I did realize that the LED of the devices flashes very fast if my connection is 100%. It starts to (progressively) slow, when no traffic is present. So maybe this problem is a power management issue? It seems the device won't "wake up" and strenghten it's signal output if it is needed.

Is this a drivers issue? Any suggestions for further analysis this problem? Any advice / solution to overcome this issue?

(Sorry for my, eventually a bit, awkward english, i'm not a native speaker ...)

ad-hoc mode issues

There seem to be issues with ad-hoc mode (short version: it did not work on my gentoo machine). is ad-hoc mode supported by this driver?

long version:

after iwconfig wlan0 essid daihinia mode ad-hoc on two machines with tl-wn723n I get this:

machine 1:

Mode:Ad-Hoc Frequency:2.412 Ghz Cell: 02:11:87:C6:B2:FE
Link Quality:0 Signal level:0 Noise level:0

machine 2:

Mode:Ad-Hoc Frequency:2.412 Ghz Cell: 02:11:87:6A:20:FF
Link Quality:0 Signal level:0 Noise level:0

Then there is no way I can get them to be in the same cell, and ping does not work between them (after setting them to the same network with ifconfig)

possibly related, I get this in the log:

[45541.999446] Chip Version Info: CHIP_8188E_Normal_Chip_TSMC_A_CUT_1T1R_RomVer(0)

I can provide more details if needed.
Thanks.

Make all error

When i run make all i have the following error:

make ARCH=arm CROSS_COMPILE= -C /lib/modules/3.10.21+/build M=/usr/src/rpi-rtl8188eu modules
make: *** /lib/modules/3.10.21+/build: No such file or directory. Stop.
make: *** [modules] Error 2

Why does it need to go to /lib/modules/3.10.21+/? Shouldn't this point to Kernel sources?

Can't connect to anything on a TL-WN725N

Initially I bought these dongles to use with a Raspberry Pi but as it turns out, I can't get them to work under Linux at all.

To clarify, I also attempted to use them on a desktop computer running Ubuntu (x64) 12.04 so I'm pretty sure it's not a power issue.

What I did was:

• Installed the kernel headers package
• Cloned this repo
• Compiled the code (make all, make install)
• Loaded the module and copied the firmware file into place

Now I was trying to use wpa_supplicant to connect to a WPA2 network and all I keep getting on /var/log/syslog is:

It's essentially stuck in a cycle of indicate disassoc and assoc success and it never really connects to the network. Concretely, iwconfig shows:
wlan0 unassociated Nickname:"WIFI@REALTEK"
Mode:Managed Frequency=2.462 GHz Access Point: Not-Associated
Sensitivity:0/0

Power Management:off

Tx excessive retries:0 Invalid misc:0 Missed beacon:0

And lsub shows:
Bus 001 Device 002: ID 0bda:8179 Realtek Semiconductor Corp.

One thing that I found interesting is that when I run two instances of wpa_supplicant, it does connect to the AP for a fraction of a second and then goes again to unassociated.

I've also tried changing my network to no security at all and connecting via sudo iwconfig wlan0 essid "ssid" but no dice. It just doesn't associate.

Any ideas? Is the driver broken or is my device broken? Or am I doing something wrong?

ioctl[SIOCSIWAP]: Operation not permitted

I'm using a TP-LINK TL-WN725N v2 on a Raspberry Pi with ArchLinux on it.

The module compiles and inserts fine. But I have trouble connecting to my wireless network. I think calling wpa_supplicant generates a warning that gets interpreted as a an error by Arch's netctl tool for network connection.

In any case, wpa_supplicant can be successfully called manually, followed by dhcpcd. But the ioctl error is always present:

sudo wpa_supplicant -Dwext -iwlan0 -c /etc/wpa_supplicant/mynet.conf                           
Successfully initialized wpa_supplicant
ioctl[SIOCSIWAP]: Operation not permitted

wlan0: WPA: Key negotiation completed with **:**:**:**:**:** [PTK=CCMP GTK=CCMP]
wlan0: CTRL-EVENT-CONNECTED - Connection to **:**:**:**:**:** completed [id=0 id_str=]

Then, in another terminal:

sudo dhcpcd -A wlan0

Network is then working.

I guess that without the ioctl error, the higher-level tool netctl would work and connect.

What could be causing this issue? The module once worked with raspbian but I think it was an older kernel. Maybe raspbian's network tools ignored the ioctl error...

Kernel version is 3.6.11-17-ARCH+.

Latest version compiles OK but doesn't work

Hi,

First of all thank you for your great work. I've searched the net for a driver able to compile on 3.11 kernel and found that yours is the only one.

After some time passed on tests, I finally managed to have it compile on 3.11 and successfuly loaded. FYI your latest Makefile doesn't install the firmware recently extracted from sources so I had to copy it by hand. Not easy to find (modprod and iwconfig works, only ifconfig complains a little bit) but the debug option helped me a lot :-)

But... my issue is that even after having followed all these steps, I can connect to my network but I get so slow bandwith (less than 1 Mb/s) that I disconnect all the time and obviously can't use my usb wifi network adapter.

I face the same issue on 3.8, 3.11 and 3.12 RCs.

My "official" environment is Ubuntu 13.10 64bit with the following uname -a:
Linux VivoBook 3.11.0-12-generic #19-Ubuntu SMP Wed Oct 9 16:20:46 UTC 2013 x86_64 x86_64 x86_64 GNU/Linux

I've run the module with debug level 5 and 9 and found a bunch of the following messages:
rtw_free_xmitframe():pxmitframe == NULL
recvbuf2recvframe: rtw_recv_entry(precvframe) != _SUCCESS

Let me know what information you need and I will provide it to you quickly.

Regards

TP-Link TL-WN725N keep connecting and disconnected then.

First thanks to Larry, it works well until I update to the latest version b49674f.

After I updated, make, then install as usually. It seems OK but when I restarted the machine, there comes the issue, the usb card can connected to wifi, but the signal strength is very weak, so it disconnected shortly, but I know this is not true, they are very close.

I guess there must be some issue in signal strength measuring, any other guy got the same issue? Or my card is broken?

Many thanks!

No N speed on Raspberry Pi+OpenELEC

I have the TP-Link WN725N connected directly to a Raspberry Pi Model B, running latest stable version of OpenELEC. It works out of the box regarding general connectivity. But it only gets a max speed of 54 Mbps. If I reconfigure the router for N connections only, the wifi doesn't get discovered at all by the Pi. The Pi gets its juice from a 2.4A power supply.

Unable to unload 8188eu module compiled on the RPi

Ref issue #37

I have solved this issue by updating gcc on the Raspberry Pi to gcc-4.7 and updating the /usr/bin/gcc symlink to point to gcc-4.7.

Using gcc-4.7 the module, and others I've tried, now unload without problems and cat /proc/modules shows

8188eu 795982 0 - Live 0xbf046000 (O)

and [permanent] has disappeared.

And surely the patch to the Makefile is also not necessary. Isn't just adding the symlink

sudo ln -s /lib/modules/kernel version/build /kernel/source/directory

to the system doing the compile sufficient.

I am currently running Raspbian 3.10.27+ #630

Insanely slow and unstable work on D-Link DWA-125/D1/4.0

All works only few seconds after connection. Signal level is about 2% in a meter away from the router :(

Unknown symbol in module on Nvidia Jetson tk1

Hi

I'm trying to make a rtl8188eu wifi dangle (mercury 150) works with nvidia Jetson tk1 development board, I have overcame few issues by looking through old posting, and was able to compile the code into a ko file, but the driver could not be loaded for some reason.

The symptoms is the driver could not be loaded, "modprobe 8188eu" shows following error:
modprobe: ERROR: could not insert '8188eu': Unknown symbol in module, or unknown paramter (see dmesg).
The "dmesg" shows which symbol is unknown:
8188eu: version magic '3.10.24 SMP preempt mod_unload ARMv7 p2v8 ' should be '3.10.24-g6a2d13a SMP preempt mod_unload ARMv7 p2v8 '
8188eu: Unknown symbol wireless_send_event (err 0)

The Jetson TK1 uses ubuntu kernel 3.10.24, here is a list of steps I have performed:

1. unzip the kernel source into /usr/src folder.
2. fixed the symbolic link of folder /lib/modules/3.10.24-g6a2d13a/build and /lib/modules/3.19.24-g6a2d13a/source.
3. In /usr/src, run make menuconfig, selected the "Device Drivers->Network device support->Wireless LAN->USB ZD1201" (This is for the CONFIG_WEXT_PROV to be y), and the "Realtek wireless card support" in the same folder. "Networking support->Wireless->cfg80211 wireless extensions compatibility" (There is a posting on the internet says this might helps with the issue).
4. do a make in /usr/src/, do a make in rtl8188eu folder
5. copy the ko files from /usr/src to /lib/modules/3.10.24-g6a2d13a/kernel
6. in /usr/src, run "make modules_install install", reboot
7. run make install in rtl8188eu folder.
8. in /etc/modules add an entry for 8188eu
9. reboot

Could you please point out where the issue could be?

Thanks
JJ

Not build driver for kernel 3.10.29+

Today i update the kernel of my RasPi to version 3.10.29+ (Debian).
Take kernel source by https://gist.github.com/azbesthu/3893319 and rebuild rt8188eu driver with latest updates (i made fetch from rep) successfully.
But after install driver my WiFi adapter don't work.

mkdir -p /lib/firmware/rtlwifi

reboot and after them

freezing

Hey good evening, I installed this driver for linux mint 13 xfce maya, I have updated since a few days the sources.list to linux mint 15 olivia, the card works great but my pc is freezing 10 minutes after connecting without open any program, any solution to this problem that someone can tell me.
Thanks.

How to change VID / PID RTL8188ETV?

Hello!
I'm trying to change the VID and PID of my RTL8188ETV Adapter to use it as Samsung-navite adapter. Unfortunately, there is no information how to do this in the whole internet. iwpriv shows the api, but i can't figure out how to use it to solve my problem. Could you, please, help me?

Mercury MW150US V2 has some issues with this driver

First of all, under the Ubuntu 13.04, OS can't display the signal strength.
Then, I can't use 'airmon-ng start wlan0' to make wireless card switch to monitor mode.One of possible reasons is that airmon-ng can't recognize the chipset because of the driver.
These problems can be resolved?
Thank you for your work！
