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

[ilCONDOR]

Hi guys,

I have just updated my RaspPi 2 to the last kernel version 4.4.11.

I was wondering when appropriate drivers will be released.

Thank you

This project is really amazing but I wonder why this driver is not in the official repositories?

Not being in the official repositories is really a pain when you update your kernel.

As far as I know, if you update your kernel via SSH... and if you don't have a wired connection... and even if you have a keyboard and LCD for local access... the adapter will no longer works, thus no Internet so no easy update...

This means that you need another computer to download the driver, put the driver into a pen, plug the pen in the Rpi, access the Rpi locally (needs a keyboard and LCD) and manually update the driver.

Right?!

Even though, keep it up

There is a driver now included in the image which will handle this wifi adapter but if you have been using the driver I compile it will be disabled. You can enable the built in driver by deleting the file /etc/modprobe.d/8188eu.conf which includes the line blacklist r8188eu which stops the built in driver loading. There are, however, a number of folks who appear to prefer the driver I compile which is why I still compile it.

I have a script which will allow you to update my driver if you do a kernel update using rpi-update. This will allow you to run rpi-update and then before rebooting update the driver to the one for the new version of the kernel. Then after rebooting you should find your Pi will be connected to the internet via the wifi.

Try this

Code: Select all

wget https://dl.dropboxusercontent.com/u/80256631/install-wifi.tar.gz
tar xzf install-wifi.tar.gz

Then run command ./install-wifi -h to show details on how to use it.

Now I see why I was having trouble with my wifi adapter (TL-WN725N V2).

That is, my first adapter was this one (TL-WN725N V2) and I always used your driver (thanks!) which worked great.

Then I bought from eBay a RalinkRT5370 which worked out from the box on Raspbian... so I stopped using TL-WN725N V2.

However, yesterday I needed to go back to the TL-WN725N V2. As I read, a few months ago, that this adapter was now working out from the box I did not care about your driver. Well, in fact, I though it was your driver included in the image.

The problem is that the adapter with the built in driver included in the image is not working. Signal was zero (0/100) even though I have the RPi about 5 meters straightforward with no barriers from the router. I found that very strange.

So, I tried again with your driver... and guess what? Signal 100/100.

This means that it is NOT your driver on the image, and so my question is: Why use a driver which doesn't work with the version 2 of the TL-WN725N instead of including your driver?

I think the main problem with adding drivers to Linux is a general concept that the driver source should not include any firmware required and any firmware should be included as a separate binary file. This generally requires drivers that do have firmware included to be modified to remove the firmware from the driver source and added as a separate file before it can be included in the Linux source. This is what happened with the built in driver, which is now a heavily modified version of the version I used to use although I now use a rather newer version.

Thank you so much for explaining.
I'll keep using your driver with your automatic update script.

hi, MrEngman. I have a question about the source code location.

I find rtl8188eu source code from https://github.com/lwfinger/rtl8188eu, but the lastest version is v4.1.4_6773.20130222.

but your 8188eu.ko's version is v4.1.8_9499.20131104, did you modify the source code from https://github.com/lwfinger/rtl8188eu?

I meet a strange problem while using tl-wn725n v2 with raspberry A+.
At first, the wifi dongle works very well, but after some hours(30+hours or 1 hours), the singal level drops from 100% to 2% and never recover again.

If I reload 8188eu driver, the signal level will recover. The power supply is very good, 5V 5A, so I suppose it's maybe the problem of drvier?

Just to keep in mind that, with the same dongle (version 2) and while using the built in driver, I have the same issue from start.

That is, the signal is always bad... 0/100. Maybe this driver suffers from this issue but only after a few hours of work.

The source I currently use and have used for quite a while now is v4.3.0.8_13968.20150417. I downloaded it from the internet but do not remember from where.

Are you using my wifi driver or the lwfinger version? It is possible your wifi is going into power saving mode. If you are using my wifi driver do you have a file /etc/modprobe.d/8188eu.conf with contents like

Code: Select all

blacklist r8188eu
options 8188eu rtw_power_mgnt=0 rtw_enusbss=0

which disables power management.

hi, MrEngman, did you download source code from http://xiaopan.co/forums/threads/rtl818 ... 6nhv.9328/?

[MrEngman]

I don't think so. Fairly certain it was a Chinese site lazyhu or baidu but I can't access them now.

The file I downloaded was rtl8188eus_linux_v4.3.0.8_13968.20150417.zip and a search on the internet shows it available here http://filemare.com/en-gb/browse/60-249 ... 5504/Linux although I haven't verified it is identical to the file I downloaded.

Hi, MrEngman, I found the source code from tp-link website, http://www.tp-link.com/il/download/TL-W ... tml#Driver
you can follow the latest source code from here.
Concerning the sudden drop of the wifi dongle, I replaced the PSU( 8A, 5V) to exclude the PSU's problem. If I get more information, I'll post here.

Thank you

Hi,

Sorry for not responding earlier but I've been struggling all day trying to compile the driver for osmc. They really make things difficult compared to raspbian.

Anyway, you will be pleased to hear I have 4.4.8-3-osmc running with an Archer T2U wifi module connected, so hopefully it will be OK for you as well.

You should be able to download and install using commands

Code: Select all

wget https://dl.dropboxusercontent.com/u/80256631/mt7610-4.4.8-3-osmc.tar.gz
tar xzf mt7610-4.4.8-3-osmc.tar.gz
./install.sh

and install.sh is set up to install in osmc so do not edit this one

Let me know how you get on.

Don't worry, I was also working..

MrEngman.. I don't know how explain that.. You are a monster! It's working perfectly with 2.4 and 5Ghz

I didn't noticed any packed loss and testing the link, It worked at the limit of capacity

"Tx Rate" and "Rx Rate" appear to be ok too, during a standby, they decreased the signal to 6 and when I did some stuff, they increased, with "Rx Rate" topping the 433.3 at my router.

Running around one hour and everything is OK

I really would like to thank you and congratulate for your effort!
And again, If I can help with something, I'll be glad to help you

Hi,
driver for kernel version 4.4.13 available?
Thanks

Hi,
driver for kernel version 4.4.13 available?

Yes. What is the output from command uname -a so I can give you the commands to download and install the right version.

Or if you look at the major update section in the first post it will tell you how to get the right version.

[femape]

Hello,
I have problems to install the driver with Jesse distro and I accidentally run an upgrade which upgrades the kernel to 4.4.x. As the drivers are not available yet for this kernel version I decided to install an old, well known Wheezy distro:

Code: Select all

pi@raspberrypi ~ $ cat /etc/os-release
PRETTY_NAME="Raspbian GNU/Linux 7 (wheezy)"
NAME="Raspbian GNU/Linux"
VERSION_ID="7"
VERSION="7 (wheezy)"
ID=raspbian
ID_LIKE=debian
ANSI_COLOR="1;31"
HOME_URL="http://www.raspbian.org/"
SUPPORT_URL="http://www.raspbian.org/RaspbianForums"
BUG_REPORT_URL="http://www.raspbian.org/RaspbianBugs"

Code: Select all

pi@raspberrypi ~ $ uname -r
3.18.11+

Next, I run the script provided by @LaFambe (thank you again!) and I have the following setup:

Regarding the driver, I added an automount when booting in /etc/rc.local

Code: Select all

##!/bin/sh -e
#
# rc.local
#
# This script is executed at the end of each multiuser runlevel.
# Make sure that the script will "exit 0" on success or any other
# value on error.
#
# In order to enable or disable this script just change the execution
# bits.
#
# By default this script does nothing.

# Print the IP address
_IP=$(hostname -I) || true
if [ "$_IP" ]; then
  printf "My IP address is %s\n" "$_IP"
fi

sudo modprobe 8188eu

exit 0

The interfaces file is this:

Code: Select all

pi@raspberrypi ~ $ cat /etc/network/interfaces
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

The wpa_supplicant.conf is:

Code: Select all

pi@raspberrypi ~ $ sudo cat /etc/wpa_supplicant/wpa_supplicant.conf 
ctrl_interface=DIR=/var/run/wpa_supplicant GROUP=netdev
update_config=1

network={
    ssid="ID_here"
    psk="pass_here"
}

The status is the following:

• ifconfig does not show any wlan0
• lsmod shows that the driver 8188eu is there
• lsusb shows that there is no Realtek USB dongle connected

BUT the blue light is on!

Then I clear the dmesg log running

Code: Select all

 sudo dmesg -C

Unplug and plug again the wifi dongle and I see this:

Code: Select all

pi@raspberrypi ~ $ dmesg

The blue light is off at this point.
Do you have any idea on what is happening? Is the driver not the correct one?

PS: In case is needed, the booting dmesg is:

Hello,
I have problems to install the driver with Jesse distro and I accidentally run an upgrade which upgrades the kernel to 4.4.x. As the drivers are not available yet for this kernel version I decided to install an old, well known Wheezy distro:

I'm not sure why you are having problems. And you should not need the change you made to /etc/rc.local to load the module. The dmesg output shows the driver loaded but does not show the wifi being installed. Did you reboot with the wifi connected?

Drivers ARE available for the latest kernel versions. The filename format has changed and Lafambes script will not load them. I have made a new script which can be used for Raspbian kernel versions 3.18 - 4.4 and any newer versions as they become available.

Please read the section MAJOR UPDATE:- at the beginning of the first post in this thread for details of the filename format and how to download and install them. Details of the new script are also available which can be used to automatically select the correct driver and download and install it.

I would suggest download the new script and run it to load the correct driver.

Thank you for the information MrEngman, I decided to try with the latest distro Jessie-Lite. I put it on the SD, boot with eth connection and ran your script. At this point I had problems with the usb dongle, it was not listed on lsusb then the script could not go on. However I changed to another USB port and I saw the dongle with lsusb. At this point I was able to run the ./install_wifi.sh command.

After a reboot, the driver wasn't loaded automatically (not listed in lsmod) and this was weird. I found that my problem is a HW problem, the plastic case is really bad quality: if I apply a little force with my hand it works but if I don't apply the force it doesn't work! It was really odd that I could see the blue light but the Tx/Rx wasn't working. This took me sooo much time that I don't want to think about...

Thank you again for your time

There is a driver now included in the image which will handle this wifi adapter but if you have been using the driver I compile it will be disabled. You can enable the built in driver by deleting the file /etc/modprobe.d/8188eu.conf which includes the line blacklist r8188eu which stops the built in driver loading. There are, however, a number of folks who appear to prefer the driver I compile which is why I still compile it.

I have a script which will allow you to update my driver if you do a kernel update using rpi-update. This will allow you to run rpi-update and then before rebooting update the driver to the one for the new version of the kernel. Then after rebooting you should find your Pi will be connected to the internet via the wifi.

Try this

Code: Select all

wget https://dl.dropboxusercontent.com/u/80256631/install-wifi.tar.gz
tar xzf install-wifi.tar.gz

Then run command ./install-wifi -h to show details on how to use it.

MrEngman

Have not registered here until now, but i have to say thank you!
I got my pi zero v1.3 and my wn725n adapter was between 0-10/100 in signal while being 2-3 meters from the router.
After i ran this script and used those drivers instead i have a signal between 99-100/100.

Don't know how it could be such a difference but it is.
