This will take quite long…

Note: If you don’t want to wait follow the instructions in how to install TP-Link TL-WN725N version 2.

git clone https://github.com/liwei/rpi-rtl8188eu.git
git clone --depth 1 git://github.com/raspberrypi/linux.git rpi-linux
git clone --depth 1 git://github.com/raspberrypi/firmware.git rpi-firmware
cd rpi-linux
make mrproper
zcat /proc/config.gz > .config
make modules_prepare
cp ../rpi-firmware/extra/Module.symvers .
cd ../rpi-rtl8188eu
CONFIG_RTL8188EU=m make -C ../rpi-linux M=`pwd`
sudo rmmod 8188eu
sudo install -p -m 644 8188eu.ko /lib/modules/`uname -r`/kernel/drivers/net/wireless
sudo depmod -a
sudo modprobe 8188eu

This is the 8188eu.ko I compiled my self.

Can you help us by specifing how should a noob behave in front of the hundreds of options when running “make modules_prepare” ?

  If you are a total noob you should just download the precompiled driver from here: http://tech.enekochan.com/2013/05/29/tp-link-tl-wn725n-version-2-in-raspberry-pi/
  
  In other case, just press enter to every question to use the default answer.

I’ve got this wifi dongle, I’ve the intention to use it in a prototype I am working on (http://traffic.integreen-life.bz.it/wiki/prototype),
Do you know the difference between the two repositories github.com/lwfinger/rtl8188eu and github.com/liwei/rpi-rtl8188eu; I successfully compiled and used both.

  I read somewhere that one of them used the blue led to show status of connection and such. I don’t know the internal differences.

Hi there,

i can’t use the precompiled driver. Therefore i tried it on my own and got stugged here:

sudo zcat /proc/config.gz > .config
-bash: .config: Permission denied

How shall i get over this?

  Try it without sudo, as I wrote up there. May be also yo u have your SD card write protected?

Hey thx for reply,

long story short, i made it. I had to create the emtpy file first, then chmod rights on it and that made the trick.
Now i got my Pi running the TL-WN725N V2 on Soft-float Debian “wheezy” (2013-05-29-wheezy-armel).
Therefore i would like to e-mail the file one of u to share it under github. Any volunteers?

  Are you using Raspbian?

    No, I’m sorry… I was trying with xbian

    anyway, xbian is based on raspbian, is there anything else I can do?

      Google for “xbian /proc/config.gz”. Second result:
      
      check kernel .config setup (under /proc/config.gz – if missing, do a “sudo modprobe configs”).

Hi,
thanks for this info!
I built the module, but I get the following error with my and yours .ko
“root ~/tplink/rpi-rtl8188eu # modprobe 8188eu
ERROR: could not insert ’8188eu’: Exec format error”
Do you have an idea of what is going wrong here?

Thanks
Dennis

I tried these instructions on my RPi model A, raspberrypi 3.6.11+ #541 PREEMPT, based on the original Wheezy images and all the updates.
But it seems the last update breaks the driver.
I followed all the steps, not an single error until last step “sudo modprobe 8188eu”, ERROR: could not insert ’8188eu’: Exec format error.

Please help, I tried so many other webpages and this one looked promising.
