Support #408
Updated by Daniel Curtis over 9 years ago
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. <pre> uname -a </pre> > 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. h3. rtl8188eu drivers for 3.6.11+ * 3.6.11+ #371 up to #520 inclusive - 8188eu-20130209.tar.gz * 3.6.11+ #524, #528, #532 - 8188eu-20130815.tar.gz * 3.6.11+ #538, #541, #545, #551, #557 - 8188eu-20130830.tar.gz h3. rtl8188eu drivers for 3.10.18+ to 3.10.38+ * 3.10.18+ #577 - 8188eu-20131105.tar.gz * 3.10.18+ #579, #585 - 8188eu-20131106.tar.gz * 3.10.18+ #587 - 8188eu-20131110.tar.gz * 3.10.18+ #590, #592 - 8188eu-20131111.tar.gz * 3.10.18+ #594, #596 - 8188eu-20131113.tar.gz * 3.10.19+ #600 - 8188eu-20131113.tar.gz * 3.10.21+ #602, #604 - 8188eu-20131113.tar.gz * 3.10.22+ #606 - 8188eu-20131206.tar.gz * 3.10.23+ #608 - 8188eu-20131209.tar.gz * 3.10.24+ #610 - 8188eu-20131209.tar.gz * 3.10.24+ #614 - 8188eu-20131219.tar.gz * 3.10.25+ #616, #618 - 8188eu-20131219.tar.gz * 3.10.25+ #622, #624 - 8188eu-20131219.tar.gz * 3.10.26+ #628 - 8188eu-20140110.tar.gz * 3.10.27+ #630 - 8188eu-20140117.tar.gz * 3.10.28+ #632, #634 - 8188eu-20140117.tar.gz * 3.10.29+ #636, #638 - 8188eu-20140117.tar.gz * 3.10.30+ #640, #642 - 8188eu-20140117.tar.gz * 3.10.32+ #646, #648 - 8188eu-20140117.tar.gz * 3.10.33+ #654, #656 - 8188eu-20140117.tar.gz * 3.10.33+ #658 - 8188eu-20140117.tar.gz * 3.10.34+ #660, #661 - 8188eu-20140117.tar.gz * 3.10.36+ #662, #664 - 8188eu-20140117.tar.gz * 3.10.36+ #665, #666 - 8188eu-20140117.tar.gz * 3.10.37+ #667, #669 - 8188eu-20140117.tar.gz * 3.10.38+ #675 - 8188eu-20140117.tar.gz h3. rtl8188eu drivers for 3.12.18+ to 3.12.22+ * 3.12.18+ #673, #677 - 8188eu-20140425.tar.gz * 3.12.18+ #679, #680 - 8188eu-20140501.tar.gz * 3.12.19+ #681, #682 - 8188eu-20140509.tar.gz * 3.12.19+ #684 - 8188eu-20140509.tar.gz * 3.12.20+ #685, #686 - 8188eu-20140509.tar.gz * 3.12.20+ #687 - 8188eu-20140509.tar.gz * 3.12.21+ #688, #689 - 8188eu-20140509.tar.gz * 3.12.22+ #690, #691 - 8188eu-20140616.tar.gz 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 <pre> 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 </pre> 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. h2. Compiling from Source h3.
