Re: (UPDATE) Drivers for TL-WN725N V2 - 3.6.11+ -> 3.12.36+

Sat Feb 07, 2015 10:57 pm

Hi,
I tried to install driver for my wireless TP-link following this tutorial but it doens't works.
My version is

Code: Select all

3.12.35+ #730, #733 - 8188eu-20141107.tar.gz
The issue is that as soon as I type

Code: Select all

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
The ping to 8.8.8.8 was ok!
After, I rebooted my r-pi and no networks are availables.
If I type

Code: Select all

sudo ifconfig
I can see eth0 and wlan0 interfaces.
Where is the error?

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 am currently using the built-in driver and firmware from the link above, but the connection is very unstable. When connecting via SSH the connection is often broken before I manage to enter the password. If I manage to log in, the terminal is quite responsive as log as I keep writing. If I stop even for a couple of seconds, the connection often breaks. Also I've noticed that repeatedly invoking

Code: Select all

iwconfig wlan0
will make the signal strength increase to quite high values (60-70), but leaving it for a couple of seconds and invoking the command again will show signal strength of about 0..2. Another thing is that I'am only able to establish one SSH connection at a time (I'm not sure whether this is related). I tried multiple power sources ranging from 1 to 1.2 Amps, but it made no difference. The wifi dongle is the only USB device I'm using. I have a Pi 1 B+.

Code: Select all

root@raspberrypi:~# uname -a
Linux raspberrypi 3.18.6+ #753 PREEMPT Sun Feb 8 14:47:22 GMT 2015 armv6l GNU/Linux

Code: Select all

root@raspberrypi:~# cat /etc/modprobe.d/r8188eu.conf
options r8188eu rtw_power_mgnt=0 rtw_enusbss=0
Any ideas? Sorry for my English.

since you are not the only one with wifi problem with 3.18 firmware, can i ask you your device's usb id?
I am on 3.18.5+ and my 725N connection is rock solid.

Mine is 0bda:8179

Hi!

Just want to let you know that I have installed the latest driver (posted some pages ago), and my connection keeps on falling. If I unplug and re-plug the dongle it starts working again.
Since I only SSH into my pi (I use it as home server), I cannot check the frequency on which this happens, but it sure does (as someone else here is reporting).

Do any of you know what we could do?

Are you (like me, and possibly fgimenez) running the dongle without a powered USB hub? I'm almost sure this is a power thing...just waiting to receive powered USB hub.

Mine wont even start after the update/upgrade, an hour ago
happened before rpi-update (previous was 3.12.35+ #730)
then tried rpi-update
same results
then tried with 8188eu-20150114.tar.gz and the 725 unplugged, error occurs "Invalid module format" on insmod command (expected maybe?) i cant get the pi working with the 725 plugged in

usb id 0bda:8179
3.18.6+ #753

red and green constantly on and the pi is getting hot, monitor is on nothing on screen
i wont try the unplug and plug again method, the last one fried

Yep, no powered USB hub.

Maybe it is a power is power thing, but I guess we need to solve this... The dongle worked perfectly before, so sure the Pi has enough power to make it run now...

They included the driver in the new firmware but it's unstable (i get 0-2 signal strenght instead of 70-80) because it's not the same driver. We need an updated version of MrEngman driver. Thanks

just to help understanding the problem :)

1) i'm running my dongle without a powered usb hub. On the other USB (i'm on a B model) i have another device (not power hungry, it's a temperature sensor)
2) i do not (do not) have any /etc/modprobe.d/r8188eu.conf file

And yes, my connection is rock solid. Can't understand this. Can i make some test for you?

Thanks! What are the specs of the power supply you're using? And what does your /etc/network/interfaces look like?
Unfortunately I cant upgrade to 3.18.xx to look at logs, but i remember something along the lines of "failed to initialize driver" in one of the logs I read. NOTE: this is not when the adapter disconnects, but rather when I try

Code: Select all

sudo service networking restart
to try and reconnect to my AP.

Here it is

Hi,
there is a bug between this driver for 3.12.35+ #730, #733 - 8188eu-20141107.tar.gz and logmein-hamachi.
I spent an entire morning to understand that both do not work.
As soos as I install logmein-hamachi (after installing TP-link adabter's driver) the wifi network is down.
With lan connection there are not problems.
Do you know how to solve this issue?
Meanwhile I ask the same question to official hamachi support.
Thanks.

For the records, when I woke up today I found my connection down.
I un-plugged and re-plugged my dongle, and started seeding some torrents. I have not lost the connection for about 10 hours, but maybe it is because my torrents keep on seeding...

Hi all,
I have the same problem. After upgrade to 3.18.6+ the the dongle doesn't work fine. The connect is very unstable and very slow. Now the signal strength is 2. Before the the upgrade it was normally 80-90.

The driver inside the new firmware version doesn't works fine.
Could you help me? What can I try to fix the problem? Any suggestion?

Thanks.

Yeah your link quality is also 0 while mine (remember I went back to 3.12) is 92. What is going on?

I have a strength of 98 in my iwconfig, still my connection drops now and then and I have to unplug and replug the dongle.

Any suggestion? Any verification I could do?

hi,
I have a Raspberry pi 2, running 13.18.5-v7 and I have spent all day trying to install drivers for a TL-WN725N.

I have followed (some) instructions on many threads but not having any luck... Can anyone point me in the right direction?


Cheers in advance!

You don't need to iinstall driver for TL-WN725N. Kernel 13.18.5-v7 already contains the necessary files. You must check firmware file in rtl8188eufw.bin /lib/firmware/rtlwifi
and check that r8188eu not in modprobe blacklist

I'm subscribing to this thread !

I'm experiencing the same difficulty with raspbian 3.18.35+, the signal strength is "jumpy" to say the least.

Several speedest.net tests went fairly well, then the speed went down to a crawl after testing big files transfer.

For the time being, i'll stick with my former 3.12.35+ #730

PS : my device ID is 0bda:8179

I also have a problem with Pi 2 and TP-link WN725N on 13.18.5 v7
When I installed the firmware:
sudo wget https://github.com/lwfinger/rtl8188eu/r ... 88eufw.bin -O /lib/firmware/rtlwifi/rtl8188eufw.bin
It can connect to my network, but it keeps on connecting and disconnecting in a loop, every few seconds.
there is no blacklist in etc/modeprobe.d/

thank you,

Dongle wasn't showing and in isusb and no lights..

There was no rtl8188eufw.bin in /lib/firmware/rtlwifi.

Moved file (finally learnt how to move files outside the gui (I was denied permission, when I c&p'd)) now after reboot I have a light on and the dongle is showing up in lsusb.

Still not getting a wlan option in wpa_gui. but the flashing light is like a mile stone!... oh it stopped flashing :(

oh and it's not listed in modprobe.

just a FWI update, however any further hand holding would be great.

Cheers
