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

[MrEngman]

Thanks, MrEngman.

I don't mind formatting the sdcard and installing the new kernel. But the last raspbian distro in Downloads, from 7th of Jan, is still with 3.10.25+. Where can I get the last distro??

Thanks again,
Jose

There are details on all the driver versions including for 3.10.25+ in the first post in this thread. http://www.raspberrypi.org/forum/viewto ... 82#p462982 and some basic configuration data here http://www.fars-robotics.net/ which now includes the driver info.

If you want to update to 3.10.27+ you can run commands

Code: Select all

sudo apt-get update
sudo apt-get upgrade
sudo rpi-update

MrEngman

[jperedadnr]

Thanks DougieLawson, thanks MrEngman

Upgraded to 3.10.27 done. Upgraded TL-WN725N V2 with #630 kernel, too.

Now iwconfig shows "Link Quality 27/100 Signal level=-64 dBm", while in mi older Pi (3.6.11+, same wifi adapter) I have at the same time "Link Quality 97/100 Signal level=54/100".

I think there's been an improvement in the wifi speed, but it seems not quite stable (drops to 9/100 sometimes), and it's 2 or 3 times slower than the other Pi.

Any idea will be welcome. Thank you!
Jose

[mclaser]

Thanks everyone for all the info here!
I'm having a problem after the kernel upgrade from 3.10.25 to 3.10.27. I have the TP-Link TL-WN723N V3 adapter. I had to go through a little song-and-dance (rebuild the driver I think, I didn't take good enough notes) to get this adapter to work on 3.10.25 but it was working great for
a week until I got the bright idea to update the kernel. I've read through 90% of this treat (and others). I downloaded ...20140177 and installed without error per instructions. As you can see in the dmesg I get some errors. Also if I ifup wlan0 I get errors. You can see in iwconfig that the adapter comes up and associates, but then it drops the connection after ~10 sec. When it's up I can ssh in from my PC, ping in/out, whatever. I can watch it pop up in wifi-config gui and then disappear after a few seconds. If I ifdown wlan0, then ifup wlan0 it comes up again, but drops out once more. Help me please!! THANKS!

(sorry, I can't figure how everyone's getting nice screen captures so I had to >> outputs and edit)

Update:
After some additional testing is seems like the adapter will continue to work as long as I'm using it. I removed it from the pi and installed it in the side of my monitor (hub of unknown power). It started working, but then I stopped accessing it for a a minute or so and it stopped again. Thinking it might be a power issue I plugged it into a powered hub. It was working, I started X and browsed, did a speed test, etc. everything was fine for several minutes. I started doing something else on my PC and when I looked at it it had stopped again -- the lights went out. Doing a ifdown/ifup always brings it back, but with the above indicated errors. Is it possible that there is some power saving mode where it shuts off after some period of inactivity?

[Tamayovski]

Hi!

I'm a newbie in raspberry pi bussiness. I have a TL-WN725N V2 and raspbian 3.10.25 #622

My problem is I have followed every step on this post but my raspberry never show my wifi adapter in lsusb or lsmod.

I don't know what is wrong... I feel very frustrated for this...

I tried to install with the LaFambe´s shell script but my rpi launch command not found error...

I think I going to practice my budo taijutsu techniques with the pi...

Edit: I just finished the raspbian installation if you think is better install other version I'll do, but now I don't know which

Thank a lot for your support

EDIT 2: Solution/
First search a driver for your raspbian version here (top post): http://www.raspberrypi.org/phpBB3/viewt ... 28&t=62371
Now, download it from http://dl.ciph.se/raspberrypi/. This is a alternative server courtesy of Ciph user (Thanks a lot).

Once you get your driver extract the ko file and put it in your current work folder and do this:
1. Remove old drivers or failed attemps.

Code: Select all

sudo rmmod 8188eu

2. Install new drivers.

Code: Select all

sudo cp 8188eu.ko /lib/modules/`uname -r`/kernel/drivers/net/wireless/ 
sudo depmod -a 
sudo modprobe 8188eu

3. Now ifconfig show wlan0. Congrats!

Second and optional block step.
Install Wicd-curses

Code: Select all

sudo apt-get update
sudo apt-get install wicd-curses

And now... launch it

Code: Select all

sudo wicd-curses

Attention:
If wicd not show propper wlan0 go to prefs (press p or shift+p) and in the wireless interface field just write wlan0.
Then press F10 for save.

I hope my solution for install driver will be usefull for everyone.

My English can have dramatic mistakes, sorry about that.

[new_user]

Sadly I am having issues with the latest version of the driver, any idea what this may cause?
I am able to get it up and running, but wlan0 freezes frequently after various timeframes.
If connected via eth the pi is still accessible, therefore it must be something with the wifi.

I've tried Tamayovski's instructions but I still have the same symptoms.
I have the same issue as new_user.

[mclaser]

I got frustrated and ordered the Edimax EW-07811UN as it was only a few bucks. When I plug it in I get exactly the same symptoms as described above. Can someone please tell me how to rip out the old driver and breath life into this thing? I was under the impression that the Edimax was supposed to work out of the box. ...I guess this means that the adapter is not the problem? Must be something else..

[jozo]

Thank you MrEngman. With raspbian 3.10.26+ #628 and your release 8188eu-20140110.tar.gz, I finally got hostapd working with my TL-WN725N V2.0. I followed this instruction: http://raspberry-at-home.com/hotspot-wifi-access-point/.
/ Bengt-Erik

Hi beliaz, it's great to see it's working as an AP for you, giving me at least some hope after all the days spent without any success. I've tried the kernels 3.10.25+, .26+ and .27+, none working with hostapd - always failing with:

Code: Select all

nl80211: 'nl80211' generic netlink not found
Failed to initialize driver 'nl80211'

What driver have you used in the hostapd.conf? Also, if you have any hints, it would be much appreciated. Thanks.

Jozo.

Hi guys,

I am absolutely new to the r-pi. I have some absolute basic understanding of ubuntu etc. and now I am stuck with the wifi. It is frustrating. My main problem is actually that I have the feeling that my version is a bit strange?!

Linux raspbmc 3.10.24 #2 PREEMPT Mon Dec 23 05:18:12 UTC 2013 armv6l GNU/Linux

am I doing something wrong? I tried to update everything.. but somehow I am not getting anywhere.
Thank you!!

Please disregard the last message. I updated everything (finally), now I installed the right driver.. now I only have to check out how to connect wifi! thank you guys a lot!!!!!

You appear to have RaspBMC installed. The driver versions I have compiled are for Raspbian. You will need to find a driver compiled for use with RaspBMC to get your wifi working unless it is already included in the linux image.

[LaFambe]

Hi MrEngman, let me renew my warmest thanks for the great job !

Your new version of the driver has apparently cured all the funky issues I had on my setup. Wifi link is now very stable, iwconfig displays correct quality indicators, random unassoc and related issues are gone. No more random clicks in audio, no more random usb-stick errors, no more DUPs, and driver unloads as expected. Are you using a new code base ?

Hi LaFambe,

Yes, I've changed the driver source to this http://lazyzhu.com/file/RTL8188EUS_RTL8 ... 131104.zip

There were a number of issues with lwfinger's version of the driver.

1. When compiled directly on the Pi, which is how I normally compile drivers, the module appeared to work OK but could not unload for some reason. File /proc/modules showed it marked as permanent - presumably permanently loaded. This occurred with all versions of 3.10.xx I tried. This also occurred with some other modules I tried.

2. popcornmix suggested I update gcc. I updated gcc to gcc-4.7 and the module compiled OK and would then load and unload OK but I then found it would only keep running for a few hundred seconds and sometimes much less before shutting down the connection. This was even if the power management options were disabled. The driver just kept shutting down randomly even when permanently busy. Prior to this I'd been able to run it 24/7 without any random disconnections.

I have now tried the new(different) source and it appears to have no problems at all. And no need for separate firmware files either. Not a single unexpected disconnect even when left idle for extended periods. Had to patch it to get it to compile. Patch details here.


MrEngman

[LaFambe]

Do you know which version of the driver source is eventually going to end-up in the standard kernel ? I was under the impression that lwfinger's code base was already in staging for 3.12.

[MrEngman]

Unfortunately probably lwfinger's. Why the original Realtek drivers cannot be used I don't know. I find it particularly annoying that it requires a separate firmware file. Doesn't make life easy when trying to include the driver in images like Berryboot. I'm still stuck trying to figure out how to get the firmware automatically installed.

Rather like the situation with the rtl8188cus driver. Back in the early days of RPi there was a driver that did not work and still doesn't as far as I know. I started compiling the official Realtek driver and made it available via dropbox. Finally someone saw sense and included that in the RPi linux source and it is still in use and working fine as far as I know for most people today.

[Snortoise]

Hi there,

I am running Rasbian-Wheezy, 3.10.27+ #630

I have installed the driver manually and using LaFambe's script but the dongle either freezes(LED stops flashing) or shuts off(LED turns off) at random times but it always seem to be less than a few minutes. Is there anything I can do to correct this problem? What information can I provide you with?

Thank you for your help and thank you for everything you've already done Mr.Engman and LaFambe

[MrEngman]

I would suggest running command sudo rpi-update which will update raspbian to 3.10.28+ #634 and then install the latest driver, 8188eu-20140128.tar.gz.

MrEngman

Edit: snortoise, I have updated the driver for 3.10.27+ #630 which should fix the problems you found with the older version. So if you haven't updated to 3.10.28+ install the updated driver for 3.10.27+ and you should find it works OK now.

[LaFambe]

Hey Snortoise, after running sudo rpi-update as suggested by MrEngman, sudo reboot, then run ./install-8188eu.sh and you should be up with your new driver.

[drbarj]

Hi MrEngman and thank you for all you do,
The adaptater works well when I did manually the driver's updated but when I reboot the RPi, I loose all what I did before.
When I reboot, it appears in the loading's script :
"8188eu : disagrees about version of symbol module_layout"
I tried to use the LaFambe´s shell script and reinstall the driver and the RPi answer that the exec format is not good.
Then I reinstall it manually and it works again.

Do you have idea about what to do that the RPi keep the memory of the driver ?
Thanks a lot for your answer.

[MrEngman]

Updated 8188eu.ko driver now available for 3.10.29+ #636
