(UPDATE) Drivers for TL-WN725N V2 - 3.6.11+ -> 4.xx.xx+

[joe90]

Thanks a lot, it was very useful for configure the wifi adapter tl-wn725nv2 on my raspberry pi a+ 3.12.35+ #730

Hi guys,

If you update to 3.18.xx+ there is a version of the driver included in the image so you don't need to download a new driver, however, it needs a separate firmware file downloading and installing.

You can download and install the driver firmware file with the single command

Code: Select all

sudo wget https://github.com/lwfinger/rtl8188eu/raw/c83976d1dfb4793893158461430261562b3a5bf0/rtl8188eufw.bin -O /lib/firmware/rtlwifi/rtl8188eufw.bin

You will only need to do this once as it does not need updating when the linux version is updated. Also you will not need to load a new driver whenever you update the linux version as the new driver is now included in the code.

Once you have downloaded the firmware file reboot the Pi to bring up the wifi.

Hi, I done this but reboot is very slowly with WiFi dongle inserted in the hub usb.
In wpa_gui adapter doesn't appear and blue LED doesn't flash.
In /lib/firmware/rtlwifi file rtl8188eufw.bin is present but with many others (8712, 8192).
Have you ideas about?

First, there are several firmware files in the /lib/firmware/rtlwifi directory. They are for other wifi adaptors and will not cause problems.

Second, if you have edited the /etc/network/interfaces file then the GUI will probably not see your wifi adapter. Change the /etc/network/interfaces file back to the original default settings and you should then see it in the GUI. The default is

Code: Select all

auto lo

iface lo inet loopback
iface eth0 inet dhcp

allow-hotplug wlan0
iface wlan0 inet manual
wpa-roam /etc/wpa_supplicant/wpa_supplicant.conf
iface default inet dhcp

Finally, I don't know why you should find it slow on booting. My Pi is OK and does not appear to have any problems with this driver and wifi module.You could take a look here to see if anyone else has your problem and if they have sorted it out or you could post an issue yourself about your problem.

Thank's for answer. I'm trying some options.

Hi
After updating to 3.18.3+ and installing the driver (thanks MrEngMan) my Pi disconnects from the network every few hours and I need to restart the networking service. Any ideas?
Thanks

Hello, can you update the driver list?
There aren't any drivers for #741 yet, and i had trouble using previous versions.

I even also compiled from the main drivers project, and didn't work.

(i had to return to 737 because of this)

Hello with :

I have : Résolution de github.com (github.com).... echec : Nom ou service inconnu.
wget : Impossible de résoudre l'adresse de l'hôte "github.com"

Sorry, I'm french and I can't translate in english...

[DougieLawson]

sudo sh -c "echo 'nameserver 8.8.8.8' >> /etc/resolv.conf"

I'm English and your French made perfect sense to me. (I've had too many years spent following Le Tour.)

[Kyar]

Oh, really? You like cyclist ?

I downloaded the file with my computer and I moved it directly in the folder. I restarted but I can't use the wifi correctly, it disconnect all times ...

EDIT : I restarted one other time and it works correctly now

With this driver, I don't need to update it every time?

[zxMarce]

Does anyone have any advice for a Pidora user?
I'm running 3.12.26 kernel and pulled down the 5-Jul-14 driver. Insmod reported a bad format.
I downloaded source from //github.com/lwfinger/rtl8188eu.git and tried to compile it. I received multiple
"LINUX_VERSION_CODE" is not defined [-Wundef]
"KERNEL_VERSION" is not defined [-Wundef]
errors.
Any thoughts?

Well, I have 2 Pi's; one at work and one at home. I intend to use Pidora because Gambas3 does work on Pidora out of the box, but it's a huge pain to make it work on Raspbian; so far I could do it only once despite several OS reinstalls. The downside is that Raspbian has good TL-WN725N v2 support as you have seen, but Pidora does not.

Nevertheless, somehow, I got the driver compiled from sources (in the Pi!) just last night, used a script downloaded from this site but had the problems you mention. For sake of post completeness, the script is this (make sure you have git installed to pull the drivers' sources, I hadn't it and the script failed at first):

Code: Select all

#!/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 wil 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

Now, I do NOT know C, I'm more a BASIC person, but having dealt with Windows API gave me some ability to -at least- read C. The problem in the driver sources is that it uses some conditional compilation directives that check a couple of symbols apparently not defined in Pidora: LINUX_VERSION_CODE and KERNEL_VERSION. Do this ring a bell?

So, I got bold and checked the source file mentioned in the error; what I did was basically comment out the offending code portions. Note that I did not remove them, just commented out so the compiler does not "see" them as valid code to compile. The offending files are:

Code: Select all

~/rtl8188eu/include/usb_ops.h (41)
~/rtl8188eu/os_dep/os_intfs.c (655, 716, 1033)  (655 was a little bit different, I had to comment the whole #IF)
~/rtl8188eu/os_dep/xmit_linux.c (120)
~/rtl8188eu/os_dep/recv_linux.c (198)
~/rtl8188eu/core/rtw_mlme.c (1615)
~/rtl8188eu/core/rtw_xmit.c (1685, 1873)

An example of line is:

Code: Select all

#if LINUX_VERSION_CODE >= KERNEL_VERSION(2, 6, 36)
  (compiler compiles this section if your linux version is 2.6.26 or newer)
#else
  (compiler compiles this section if your linux version is older than 2.6.26)
#endif

I used my not-so-almighty C knowledge to turn the example above to:

Code: Select all

/* #if LINUX_VERSION_CODE >= KERNEL_VERSION(2, 6, 36) */
  (compiler compiles this section if your linux version is 2.6.26 or newer)
/* #else
  (compiler compiles this section if your linux version is older than 2.6.26)
#endif */

The /* <whatever> */ block makes the compiler ignore <whatever>, be it code, a girl's phone number or a recipe for scrambled eggs - the compiler could not care less about it.

For every single error regarding LINUX_VERSION_CODE and KERNEL_VERSION, I did the same file editing session (used leafpad), and then retried the make all until I finally got it to compile. Then, I simply continued with make install and voilà! I now have the dongle working.

Bear in mind, though, that one of the files has an #IF dealing with kernel versions 3.xx instead of 2.xx. Be careful and choose wisely what you comment. You can find your kernel version with the uname -a command.

Hope it helps you and any other Pidora users.

zxMarce.

EDIT1: Added script source site and list of offending driver source files with line numbers.

EDIT2: Too bad - I updated Pidora's Kernel and the driver stopped working; this was expected. What was not expected, though, is the fact that the driver will compile, but will now throw the feared Invalid module format message. I'm now reinstalling Pidora to see if the problem goes away. Wish me luck!

MrEngman

Hi, sorry for delay.
Well the solution for me (to do at the first time after your installing procedure and # reboot) was simply connect Wlan adapter after launch startx.
Obviously I've a powered USB hub to do this, because if I connect Wlan adapter directly to Raspi-hub, system reboots.
If you have already connect Wlan adapter during the installing procedure that you described, in terminal, ifconfig doesn't result any wlan adapter and if you leave it connected, nothing changes after reboot. I need to reboot Raspi without Wlan adapter and done what I wrote before.
Thank's to everybody for your support: I'm really beginner

I also had that same problem. Right after running raspi-update my Pi took forever to boot. It was so slow after booting that I couldn't even shut it down by command (sudo shutdown - now), and had to unplug it.

I switched the Pi off, unplugged the WiFi card (a TP-LINK Nano TL-WN725N), then the Pi booted fine. I connected the Pi to my wired LAN, downloaded and installed the rtl8188eufw.bin firmware, rebooted the Pi with the WiFi card plugged in again, and it was back to normal speed! So... maybe the slowness issue is related to the WiFi card being plugged in, and the firmware file being missing?

Incidentally, thanks a lot for all your work on the rtl8188eu, MrEngman. Really.

Hi
After updating to 3.18.3+ and installing the driver (thanks MrEngMan) my Pi disconnects from the network every few hours and I need to restart the networking service. Any ideas?
Thanks

I experienced the same. Setting this into /etc/modprobe.d/r8188eu.conf seems to improve it a little bit:

Code: Select all

options r8188eu rtw_power_mgnt=0 rtw_enusbss=0

From what I've read online this disables power management and USB suspend for the dongle.
It improved a lot but it still doesn't work as well as the off-kernel driver.

I tried to compile the off-kernel one and it compiles but it panic'ed when loading.

I'll revert to the firmware with 3.12 kernel.

I tried that as well but it was not nearly as stable as the older drivers. Are you running without a powered USB hub as well? And what power supply do you have? I am beginning to think it is a power issue (wouldn't be the first ).

[lorigio]

I updated my pi to 3.18 and followed This post
With lwfinger driver i get 0 link quality, 2-4/100 signal level and disconnections
With firmware 3.12.36+ and MrEngman driver i get 100 link quality and 80/100 signal level.

lwfinger driver is not stable at all and i don't know why it is included in the last firmware, it breaks everything.

Please update your drivers to last firmware, MrEngman. Thanks

I have the 148f:7601 with 3.18.5+ 748 (dated 4th Feb). Added lwfinger but GUI does not see the adapter. lsusb shows it is there and the interfaces file is as you have it above. I had been using another adapter which added the SSID and pwd to wpa_supplicant.conf. Still the GUI will not see the adapter. If I try sudo ifup wlan0 it states the daemon failed to start and that there is no such file as wpa_ctrl_open. If you already have working wpa_supplicant from other adapters do you need to 'clear' anything for the new adapters to work with the GUI or CLI?

[ilovemipi]

Ignore my last post, now trying with the correct adapter 0BDA:8179.

I have so many adapters I'm easily confused.

0BDA:8179 and 0BDA:0179 are working fine.
