Description

Precompiled method

Driver files available for the TP-LINK TL-WN725N V2 and similar wifi dongles using the 8188eu driver module for systems using the Raspbian image.

IMPORTANT: First check the version of Linux you have. Use the command uname -a to find the version of Linux.

uname -a

Linux raspberrypi 3.10.24+ #614 PREEMPT Thu Dec 19 20:38:42 GMT 2013 armv6l GNU/Linux

The important part is 3.10.24+ #614. This is just an example and your version may be different. Select the right driver for the version you have from the list below.

Link to driver files - use date code from list above to download required driver
https://dl.dropboxusercontent.com/u/80256631/8188eu-201xyyzz.tar.gz

NOTE: If updating firmware revisions, say from 3.10.23+ to 3.10.24+, and they use the same driver, in this case 8188eu-20131209.tar.gz, you will still need to reinstall the driver on the newer version of Linux, even though the driver has not changed as it will be loaded from a different directory by the new Linux revision and you need to install it in the new directory.

The driver installation instructions expect you to be using Raspbian, either installed from a basic rasbian image or installed using NOOBS. The instructions are based on running from a Command Line Terminal, not a GUI (Graphical User Interface). If you are running using the GUI you will need to open a terminal window and run the commands from the terminal window but I can't guarantee they will work.

If you have a wired internet connection install the driver with the following commands

wget https://dl.dropboxusercontent.com/u/80256631/8188eu-201xyyzz.tar.gz <--set data code for driver version above
tar -zxvf 8188eu-201xyyzz.tar.gz                                         <--set data code for driver version above
sudo install -p -m 644 8188eu.ko /lib/modules/$(uname -r)/kernel/drivers/net/wireless
sudo insmod /lib/modules/$(uname -r)/kernel/drivers/net/wireless/8188eu.ko
sudo depmod -a

If you do not have an internet connection the driver file will need to be downloaded on another computer and copied to the SD card. I use a Windows laptop and will use that as an example of how to copy and install the wifi driver.

Open a web browser on your Windows computer and download the driver. Check the name of the driver file before saving it and correct it if necessary. I have sometimes found Windows tries to save the driver file as 8188eu-201xyyzz.tar.tar when it should be 8188eu-201xyyzz.tar.gz. Substitute the correct file name for "xyyzz".

Take the SD card and load it into an SD card reader on your Windows computer. Copy the driver file, 8188eu-201xyyzz.tar.gz, from your Windows computer to the SD card. Safely remove the SD card from the card reader by clicking the safe removal icon in the task bar and install the SD card in your Raspberry Pi and power on and login.

Compiling from Source

Compiling with DKMS on Raspbian (recommended)

  • Install dkms:
    apt-get install dkms
  • Get the current raspberry pi linux source:
    cd /usr/src
git clone --depth 1 https://github.com/raspberrypi/linux.git linux-`uname -r`
cd linux
zcat /proc/config.gz > .config
    • In the next step you may be prompted questions about the configuration if your /proc/config.gz does not answer them (new features for example)
      sudo make oldconfig
sudo make modules_prepare
sudo wget https://github.com/raspberrypi/firmware/blob/53d1ae311226b5cd7ea1277832139b74b2bb0f90/extra/Module.symvers
sudo ln -s /usr/src/linux-`uname -r` /lib/modules/`uname -r`/source
sudo ln -s /usr/src/linux-`uname -r` /lib/modules/`uname -r`/build

      NOTE: I needed to use the History feature on GitHub to locate the exact version I was using, in this case it was 3.12.28+
  • Get driver source
    cd /usr/src
git clone https://github.com/lwfinger/rtl8188eu.git
  • Build and install the rtl8188eu driver using dkms:
    dkms add ./rt8188eu
dkms build 8188eu/1.0
dkms install 8188eu/1.0

NOTE: I have had more trouble compiling on Raspbian than Arch, since their packages are kept more up to date.

Compiling with DKMS on Arch (recommended)

  • Install DKMS and Linux headers
    pacman -S dkms linux-raspberrypi-headers git
  • Get driver source, compile, install and load it
    cd /usr/src
git clone https://github.com/lwfinger/rtl8188eu.git
  • Build, install, and load the rtl8188eu driver:
    dkms add ./rt8188eu
dkms build 8188eu/1.0
dkms install 8188eu/1.0
  • Check that the driver was installed correctly by looking for a new network interface:
    ip link

Install from AUR on Arch

  • Install the dkms-8188eu package from the AUR:
    yaourt dkms-8188eu
    • NOTE: Yes, that is the whole process. Isn't the AUR wonderful?

Manual compilation (not recommended)

  • Get linux source code, prepare config files and create symlinks
    cd /usr/src
git clone https://github.com/raspberrypi/linux.git
cd linux
zcat /proc/config.gz > .config
    • In the next step you may be prompted questions about the configuration if your /proc/config.gz does not answer them (new features for example)
      sudo make oldconfig
sudo make modules_prepare
sudo wget https://github.com/raspberrypi/firmware/raw/master/extra/Module.symvers
sudo ln -s /usr/src/linux /lib/modules/`uname -r`/source
sudo ln -s /usr/src/linux /lib/modules/`uname -r`/build
  • Get driver source, compile, install and load it
    cd /usr/src
git clone https://github.com/lwfinger/rtl8188eu.git
cd rtl8188eu
make all
sudo make install
After this step you should have those new files installed:
  1. /lib/modules/`uname -r`/kernel/drivers/net/wireless/8188eu.ko
  2. /lib/firmware/rtlwifi/rtl8188eufw.bin
  • Load the module
    sudo modprobe 8188eu
  • Remove driver and linux source code to recover some space (around 700MB); do not run if you want to keep the code for future compilations
    cd /usr/src
rm /lib/modules/`uname -r`/source
rm /lib/modules/`uname -r`/build
rm /usr/src/linux-`uname -r`
rm /usr/src/linux
rm -R rtl8188eu

Automagic compilation

  • Script form:
    vi compile_rtl8188eu.sh
    • And add the followingL
      #!/bin/bash

# Get linux source code, prepare config files and create symlinks
VERSION=`uname -r | awk -F'.' '{print $1"."$2}'`
cd ~
wget https://codeload.github.com/raspberrypi/linux/tar.gz/rpi-${VERSION}.y -O rpi-${VERSION}.y.tar.gz
sudo tar zxf rpi-${VERSION}.y.tar.gz -C /usr/src/
cd /usr/src/linux-rpi-${VERSION}.y/
sudo bash -c "zcat /proc/config.gz > /usr/src/linux-rpi-${VERSION}.y/.config" 
# In the next step you may be prompted questions about the configuration
# if your /proc/config.gz does not answer them (new features for example)
sudo make oldconfig
sudo make modules_prepare
sudo wget https://github.com/raspberrypi/firmware/raw/master/extra/Module.symvers
sudo ln -s /usr/src/linux-rpi-${VERSION}.y /lib/modules/`uname -r`/source
sudo ln -s /usr/src/linux-rpi-${VERSION}.y /lib/modules/`uname -r`/build
# Optional
#sudo ln -s /usr/src/linux-rpi-${VERSION}.y /usr/src/linux-`uname -r`
#sudo ln -s /usr/src/linux-rpi-${VERSION}.y /usr/src/linux

# Get driver source, compile, install and load it
cd ~
git clone https://github.com/lwfinger/rtl8188eu.git
cd rtl8188eu
# This will take around 20 minutes
make all
sudo make install
# After this step you should have those new files installed:
# /lib/modules/`uname -r`/kernel/drivers/net/wireless/8188eu.ko
# /lib/firmware/rtlwifi/rtl8188eufw.bin
sudo modprobe 8188eu

# Remove driver and linux source code to recover some space (around 700MB)
# Leave those lines commented if you want to keep the code for future compilations
#sudo rm /lib/modules/`uname -r`/source
#sudo rm /lib/modules/`uname -r`/build
#sudo rm /usr/src/linux-`uname -r`
#sudo rm /usr/src/linux
#sudo rm -R /usr/src/linux-rpi-${VERSION}.y
#cd ~
#rm rpi-${VERSION}.y.tar.gz
#rm -R rtl8188eu
  • Make the script executable:
    chmod +x compile_rtl8188eu.sh
  • Run the script:
    ./compile_rtl8188eu.sh
