TP-Link TL-WN725N version 2 in Raspbian 2014-01-07-wheezy-raspbian with kernel 3.10.25+

UPDATE: Read this post if you have another version of the kernel and want use a script to compile the driver by yourself: New script to compile TP-Link TL-WN725N version 2 lwfinger driver in Raspbian

Thanks to I’ve been able to use the TP-Link TL-WN725N version 2 in the latest Raspbian 2014-01-07-wheezy-raspbian with kernel 3.10.25+. This was the procedure:

wget -O
sudo mv 8188eu.ko /lib/modules/`uname -r`/kernel/drivers/net/wireless
sudo chown root:root /lib/modules/`uname -r`/kernel/drivers/net/wireless/8188eu.ko
sudo mv rtl8188eufw.bin /lib/firmware/rtlwifi/
sudo chown root:root /lib/firmware/rtlwifi/rtl8188eufw.bin
sudo depmod -a
sudo modprobe 8188eu

Edit /etc/netwok/interfaces like this and add your networks SSID and password:

auto lo

iface lo inet loopback
iface eth0 inet dhcp

allow-hotplug wlan0
auto wlan0

iface wlan0 inet dhcp
        wpa-ssid "YOUR-NETWORK-SSID"
        wpa-psk "YOUR-PASSWORD"

Then reboot your Raspberry Pi and it should connect to your wifi network automatically. You should see the wlan0 device when running ifconfig:

$ ifconfig
wlan0     Link encap:Ethernet  HWaddr a0:f3:c1:14:53:ca
          inet addr:  Bcast:  Mask:
          RX packets:96 errors:0 dropped:4 overruns:0 frame:0
          TX packets:21 errors:0 dropped:0 overruns:0 carrier:0
          collisions:0 txqueuelen:1000
          RX bytes:18513 (18.0 KiB)  TX bytes:2746 (2.6 KiB)

  1. Hello,

    Following the cmd I get this :

    ERROR: could not insert ‘8188eu’: Exec format error

    Could you help me ?

    Best regards

  3. Hola. Gracias por tu interes.
    Estoy loco con el maldito TP-Link TL-WN725N versión 2. compilando el driver consegui que funcionara bien el año pasado. Hasta que actualice la rasp con rpi-update. Sin embargo siguiendo las instrucciones en consigo que funcione. El problema esta que en todos los casos cuando desconecto el cable de red tambien se desconecta el WiFi. Tampoco valen reinicios. Solo funciona cuando esta conectado a la lan. He instalado 14 veces el SO. Mirando comentarios solo veo que indican que se puede deber a problemas de alimentacion (no me lo creo ;-)). Socorro

    Version actual:
    Linux raspberrypi 3.10.32+ #648 PREEMPT Fri Feb 28 16:29:56 GMT 2014 armv6l GNU/Linux

    No tengo nada mas instalado. Para mi es muy importante usar el WiFi. Saludos

  4. Tengo exactamente el mismo problema que Manuel , llevo 2 semanas intentando lo pero no consigo arreglarlo, alguna idea? Gracias

  5. Hi enekochan,
    I have the same Manuel’s problem.
    The wifi works only if the ethernet cable is plugged in.
    If Raspberry starts whitout the ethernet cable, wifi doesn’t work and raspberry doesn’t complete startup procedure (I haven’t an available hdmi cable now, so I can’t see error message).
    Another thing: If I insert usb dongle or disconnect cable during running mode, raspberry shutdown but I think that it is due to low power.

    • Try compiling the drivers with this: New script to compile TP-Link TL-WN725N version 2 lwfinger driver in Raspbian
      Reseting while dongle connect/disconnect is a known issue. You can minimize it by changing 2 capacitors.

      • Hi enekochan,
        I tried with the procedure that you suggest in the new link after an upgrade to versione 33+ but the problem is the same.
        The wifi connection is good only if a cabled is plugged in ethernet port. If there isn’t a cable in the port the system continues to request an address to dhcp on eth. I think there is a problem in interfaces file.

        • update:
          It’s a power problem.
          I fixed a static ip on eth interface and leave dhcp on wlan.
          when the Raspberry starts, it doesn’t succeed to assign an ip address to wlan instance. If it starts with a eth cable between raspberry and a pc (without dhcp service on pc), it succeeds to acquire ip address and the blu led of the dongle bliks. If I unplug the cable from the pc socket, after 20 seconds, the blu led turn off and the interface lost the ip address. With these elements I think that through the ethernet cable the usb receive an extrapower.

  6. Mil gracias! me ha funcionado a la primera!!! 😉

  7. Worked perfect, step by step. Good tutorial!
