TP-Link TL-WN725N V2 works out of the box on Raspbian

[QBall1977]

Anyone looking to get this working with RaspBMC should look here.

http://smhaziq.blogspot.co.uk/2013/06/c ... er-in.html

Compiled with the RaspBMC, just copy to the correct location in libs/...

do a depmod, then modprobe as listed in earlier posts.

Works a treat.

Hello.
I have a D-Link TL-WN723N V3 and try to get it working with this driver and no luck.
http://wikidevi.com/wiki/TP-LINK_TL-WN723N_v3 says what this dongle based on RTL8188EUS.
Can anyone help me with this piece of dongle ?
ifconfig shows just eth0 and lo
seems like driver not loaded or not compatible.
lsusb shows Realtek Semiconductor Corp.
I try it on clean current image 2013-07-26-wheezy-raspbian.zip

p.s. I have another dongle also based on RT2870, but it doesn't work also

If command lsusb shows ID of 0bda:8179 for the wifi then you can load a working driver with the following commands

Code: Select all

wget https://dl.dropboxusercontent.com/u/80256631/8188eu-20130209.tar.gz
tar -zxvf 8188eu-20130209.tar.gz
sudo install -p -m 644 8188eu.ko /lib/modules/3.6.11+/kernel/drivers/net/wireless
sudo insmod /lib/modules/3.6.11+/kernel/drivers/net/wireless/8188eu.ko
sudo depmod -a

Then look here, http://www.fars-robotics.net/, to see how to configure the file /etc/network/interfaces for the wifi.

Thank you very much rpijet!

You need to also get a copy of the Linux source code for raspBMC. I'm not sure where you can find that. You'll probably need to look on the RaspBMC site. This is not the same as the raspberry pi source code for Raspbian.

You also need two other files .config and Module.symvers You can get .config using command zcat /proc/config/gz > .config on your SD card in the Pi. For Raspbian the Module.symvers file is included in the source tree. I don't know if its available in the RaspBMC source. If not you will need to compile the Linux source and this can take a long time - 10hrs for Raspbian - probably similar for RaspBMC if using the Pi.

I usually install the Linux source in a directory in my home directory and can then compile with the following

# make directory for source
mkdir src
cd src

# set up symbolic link to Linux source
ln -s /home/pi/src/linux /lib/modules/3.6.11+/build

# now get linux source code which will be put in directory linux
git clone --depth 1 git://xxxxxxxx/linux.git # xxxxxxxx = RaspBMC source directory

# now initialise source
cd linux
make mrproper

# set up .config file and prepare for compiling module
zcat /proc/config.gz > .config
make modules_prepare

# now copy Modules.sysmvers to linux source directory
cp /path/to/Modules.symvers ./

# compile module
cd /home/pi/src/rtl8188eu_source
CONFIG_RTL8188EU=m make -C /path/to/linux M=`pwd` # char ` is under ¬ character on keyboard and is not single quote '.

And now install and load the module

sudo install -p -m 644 8188eu.ko /lib/modules/3.6.11+/kernel/drivers/net/wireless
sudo insmod /lib/modules/3.6.11+/kernel/drivers/net/wireless/8188eu.ko
sudo depmod -a

This how I compile for Raspbian. The same for RaspBMC except you need the RaspBMC source, and the right Module.symvers file.

Hi MrEngman, I'm trying to do the same with the last version of xbian... I was following this guide:

http://tech.enekochan.com/2013/05/29/co ... -raspbian/

which gives almost the instructions you gave. (the guide is for raspbian)
The problem is that when I give:

Code: Select all

make modules_prepare

it starts asking me lot of questions... the first is:

Code: Select all

scripts/kconfig/conf –silentoldconfig Kconfig
warning: (DRM) selects DMA_SHARED_BUFFER which has unmet direct dependencies (EXPERIMENTAL)
*
* Restart config…
*
*
* General setup
*
Prompt for development and/or incomplete code/drivers (EXPERIMENTAL) [N/y/?] (NEW)

what do I have to do?

thank you

[MrEngman]

Hi robertjordan,

I think what you need to do is run an additional command after installing the file .config

Code: Select all

# set up .config file and prepare for compiling module
zcat /proc/config.gz > .config
make oldconfig          <-- run additional command
make modules_prepare

I think that is what you need to stop the list of question appearing but no guarantees.

This should use the default settings in the .config file instead of having to go though the list which is something I find very confusing.

Hmm. Sorry not sure what to suggest now. As far as I remember the Enter key will select the default setting, in this case N. Probably just need to go through the list responding with the Enter key.

Ok, it ended with:

Code: Select all

#
# configuration written to .config

after that that's what happened:

Code: Select all

root@xbian:/home/xbian/rpi-linux# cp ../rpi-firmware/extra/Module.symvers .
root@xbian:/home/xbian/rpi-linux# cd ../rpi-rtl8188eu

make: Entering directory `/home/xbian/rpi-linux'

  ERROR: Kernel configuration is invalid.

And so I tried with make oldconfig and make prepare, but:

You get the error because it expects make oldconfig and make prepare to be run in the Linux source directory /home/xbian/rpi-linux.

Looks like the driver module, 8188eu.ko, has finally been compiled so then you need to install it using the commands

Code: Select all

install -p -m 644 8188eu.ko /lib/modules/$(uname -r)/kernel/drivers/net/wireless
insmod /lib/modules/$(uname -r)/kernel/drivers/net/wireless/8188eu.ko
depmod -a

These commands assume you are running as root user and are in the directory /home/xbian/rpi-rtl8188eu where the file 8188eu.ko is located.

If the driver is OK then the insmod command should complete without any error.

MrEngman

I assume that probably the driver is not ok because:

Code: Select all

root@xbian:/home/xbian/rpi-rtl8188eu# install -p -m 644 8188eu.ko /lib/modules/$(uname -r)/kernel/drivers/net/wireless
root@xbian:/home/xbian/rpi-rtl8188eu# insmod /lib/modules/$(uname -r)/kernel/drivers/net/wireless/8188eu.ko
Error: could not insert module /lib/modules/3.9.8+/kernel/drivers/net/wireless/8188eu.ko: Invalid module format

[MrEngman]

Correct. For some reason the running kernel doesn't like the driver.

I think the first thing to try is to recompile the driver. This is because you configured the kernel and then ran the driver compile that failed then ran the kernel config again then the driver compile again but did not completely recompile the driver.

To recompile the driver from scratch you first need to run the command make clean. This will re-initialise the driver source and then run the driver make command again. Then try installing it again.

I would also recommend using the full path name to the Linux source in the make command e.g.

Code: Select all

CONFIG_RTL8188EU=m make -C /home/xbian/rpi-linux M=`pwd`

If you continue to get the same error it is likely the kernel source you are using is not the same used to compile the kernel you are running or the .config or Module.symvers files may not be right.

MrEngman

This is a typical error if the Linux source is not the same as used to make the running kernel. However, it could also be caused by .config not matching the settings used to compile the running kernel or the Module.symvers file is not the same as the running kernel used.

Where did you get the Linux source from and the Module.symvers file?

MrEngman

The Linux source, if I understand your question, is the last version of xbian (xbian 1.0 beta 1.1), that you can find here http://www.xbian.org/download/.
For the Module.symvers file, actually when I first ran

Code: Select all

make modules_prepare

it couldn't find it, and I read somewhere that I should first ran

Code: Select all

make modules

. But I don't know where it comes from.

Edit:

I read it here: http://unix.stackexchange.com/questions ... le-symvers

[MrEngman]

Well I tried downloading the Xbian Linux source from the github to try and compile the 8188eu driver and had various problems unzipping the source as it didn't appear to load correctly and generated some really odd errors. Tried compiling anyway and the tools needed to compile don't appear to be installed either so not much help.

Do you have a list of tools I need to load to compile code? And how did you get a copy of the source installed?

Anyway had a look at the Xbian forum and found this http://forum.xbian.org/thread-1114.html. At the end of the tread is a pointer to a compiled version 8188eu driver and it loads OK.

Save you having to compile your own, mind you I would find it useful to be able to do that somehow if I can get the source and necessary tools loaded.

I had some problem trying to use the installer for osx that you finde in the link above... so I downloaded directly the xbian image (you can find the link at the bottom of the page of download in the website of xbian) and I installed it manually following the old instructions given by the RPI site before NOOBS.
After that I needed to install just git and the development tools to use make command.

Anyway had a look at the Xbian forum and found this http://forum.xbian.org/thread-1114.html. At the end of the tread is a pointer to a compiled version 8188eu driver and it loads OK.

MrEngman

I will give it a try then, to me the most important thing is to get the adapter working... also because actually I don't understand very well what I am doing when I give all those commands to compile the driver
Anyway thank you very much for your help... Now I will try to install this

[robertjordan]

It works perfectly, thank you

Same problem here:

I'm lost, does anybody have an idea where to get the correct driver ?

This is what you're looking for https://dl.dropboxusercontent.com/u/802 ... 830.tar.gz

Install with

Code: Select all

wget https://dl.dropboxusercontent.com/u/80256631/8188eu-20130830.tar.gz
tar -zxvf 8188eu-20130830.tar.gz

The wifi you have doesn't use the 8188eu.ko driver. it uses the RTL8188CUS. The driver is rtl8192cu and should appear in the list of modules displayed by command [b]lsmod[/b] as [b]8192cu[/b]

What is the Linux image you are using - I don't recognise it - although the date and time is the same as the standard raspbian image and the rtl8188cus driver is usually compiled in the standard raspbian image.

What do you see if you run command [b]sudo iwlist wlan0 scan[/b]?
What do you see if you run command [b]lsmod[/b]? Do you see 8192cu in the list?
