I buy a TP-Link TL-WN725N WiFi mini USB net adapter for my RPi. But it does not work (can not bring wlan0 up) even I install this driver: http://blog.elevendroids.com/2012/12/pr ... 27-kernel/
I check this adapter hardware version is V2. I doubt it using different ship with V1. Check the file "netrtwlanu.inf" from windows driver. The chip is really 'rtl8188eu'. You know the v1 chip is 'rtl8188cus'. It is terrible that Realtek do not provide rtl8188eu Linux driver from official WEB site.
But I found a OEM driver from: https://github.com/Red54/linux-shumeipa ... /rtl8188eu
Download rtl8188eu from this source:
git clone https://github.com/Red54/linux-shumeipai2.git
Current knernel of RPi is 3.2.27+. Check yours by command "uname -v". I tried to compile the driver for kernel 3.2. But the driver can not working.
upgrade RPi kernel to 3.6.1:
git fetch git://github.com/raspberrypi/linux.git rpi-3.6.y:refs/remotes/origin/rpi-3.6.y
http://elinux.org/RPi_Kernel_Compilation
and recompile the 8188eu driver. install and reboot RPi Finially, the WN725N works without USb hub and connect WiFi network well. Wave~
I will update the driver and Tips later.
