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

[marciokoko]

ok now back to the wireless bit. I plugged in the tplink, it rebooted but no wireless connection. SO I created the ssh file on the memory card, put it back in, plugged the usb otg cable into the pi0 and connected it to my mac (where I logged into it before), pi0 boots up a screen saying "SSH is enabled by default, and pwd for pi user hasnt been changed, this is a risk..." but when I go to my laptop terminal and type in ssh pi@raspberrypi.local, i get ssh could not resolve:

Marcios-MacBook-Pro:~ mars$ ssh pi@raspberrypi.local
ssh: Could not resolve hostname raspberrypi.local: nodename nor servname provided, or not known

I expect this is because your connection doesn't have a DNS name server to resolve the name. Anyway using PI@raspberrypi.local is probably not right.

On my network I have to use hostname.fars-robotics.local, with no @ symbol which is probably not right to use, with hostname set for whichever Pi I want to connect to.

However, I do not normally use the hostname and always use the IP address. And on my Win 7 laptop I use Putty to make the SSH link.

There must be a load of posts about using SSH from a MAC on the forum. Maybe a good idea to look at the sticky posts at the beginning of the Beginners or Troubleshooting forums.

Hi MrEngman,

Is there any possibility that you could provide a list of the pre-compiled drivers available for download on your fars-robotics.net? I would really appreciate that! I'm running an OS that doesn't have Raspbian's extra version and build number (so I can't guess at the URL), but your drivers work beautifully otherwise.

Also, is there any chance of you uploading your source code/build configuration to GitHub? There are some (myself included) who would find it quite useful to be able to compile the drivers ourselves!

Thanks a ton. You're doing awesome work!

So what OS are you using?

I'm not going to list my drivers as there are about 1660 driver files available.

I compile new drivers whenever there is an update to https://github.com/Hexxeh/rpi-firmware and the kernel version is changed or there is a new build. Currently there are drivers for 8188eu, 8192eu, 8812au, mt7610u and mt7612u devices available for Raspbian kernels 4.0, 4.4, and 4.9.

The file names are based on the wifi version - 8188eu, 8192eu, 8812au, mt7610 or mt7612 - the Raspbian kernel version and the Raspbian kernel build number. mt7612 drivers are not available for kernels 4.9 as there is a problem with it with that kernel version and I cannot find a fix.

As an example for the latest Raspbian kernel 4.9.29(-v7)+ #1000 and driver 8188eu the file name is 8188eu-4.9.29-1000.tar.gz for Pi 1 and Pi zero and for Pi 2B and 3B 8188eu-4.9.29-v7-1000.tar.gz.

The source I use for my drivers is downloaded from github so I see no point in duplicating the code again.

MrEngman

We're running a custom OS that we've put together in-house that is loosely based on Raspbian.
Ah! I see that that repository lists the uname text. Awesome. My problem was that uname -a only gives, for example, 4.1.21, as opposed to 4.1.21v7 #872, but now I should be able to figure it out.

Thanks a ton!

Don't forget the hyphen:- 4.1.21-v7 - before the v7 for Pi 2B and 3B and just 4.1.21 for other versions of the Pi.

Would you then mind sharing (here or on first post) the specific github links for each of the driver you compile?
This can be very beneficial for this community, so that one can build same drivers with any custom kernels, such as berryboot's or al...

Thank you very much.

Hi,
I just updated my Raspberry Pi to 4.9.31+ #1005, but I can't download the driver with

Code: Select all

wget http://www.fars-robotics.net/8188eu-8188eu-4.9.31-1005.tar.gz

Hi,

I'm trying to install TP-Link TL-WN722N(EU) Ver 2.0 to Raspberry. I opened the stick and checked the Wi-Fi chip, the text on it says 'Realtek RTL8188EUS'. Based on the info I came across on various sites, I'm assuming the 8188eu is the correct driver for the stick, despite the 'S' at the end of the chip name.

I've followed the instructions provided on the first post of this thread in order to make USB Wi-Fi stick work (running 4.4.50-v7+ kernel with build #970, so downloaded and installed the contents of 8188eu-4.4.50-v7-970.tar.gz).

I'm assuming the driver is installed properly (I'm not super-experienced with Linux, though), e.g. command '$ modinfo 8188eu' lists bunch of functions available for the driver. Also, Realtek's firmware package should be installed.

Now, when I plug the USB Wi-Fi stick to Raspberry (via a powered hub), I can see on syslog some info on the new connected USB device (Realtek's 802.11n NIC), but everything seems to stop on mtp-probe checking the device and deducing the device 'was not an MTP device'.

If I run '$ sudo lshw' command, the USB device is listed as 'UNCLAIMED'.

Any idea what I'm doing wrong/missing in my system?

Hi Tenne,

The wifi module you are using is quite new and the driver version you downloaded did not include the USB ID for it as it was relatively old.

I have updated the driver so it should be OK now for the TL-WN722N v2 so can you download and reinstall it again and hopefully things should now be OK.

Hi MrEngman,

I downloaded the new tar file matching my kernel version, and now the Wi-Fi connection is working perfectly. Thanks for your tips and support!

Dear MrEngman,

While installing some of your driver under a chroot environment, I noticed some annoying discrepancy on individual drivers install scripts.
Indeed kernel variable is fixed for 8192eu, and is obtained by $(uname -r) for others (8812au, 8188eu, mt7610).
From there, install paths and depmod may gives unexpected results when installed on chroot environment.

To ensure consistency, could you consider setting same kernel version method for all drivers, with ideally the explicit kernel version number (that matches file name) ?
I doubt you can apply this change to all previous obviously, but if you could do it for the future (and ideally for old 4.4.9 family), that would be nice.

Thanks for consideration.

I have changed to using $(uname -r) for a reason and am surprised some of the 8192eu files have not been changed to use it.

Have you tried using the install-wifi script instead of downloading the driver file and using the included install.sh script?

Code: Select all

sudo wget http://www.fars-robotics.net/install-wifi -O /usr/bin/install-wifi
sudo chmod +x /usr/bin/install-wifi

Command sudo install-wifi -h shows usage details.



MrEngman

[macmpi]

Not sure install-wifi can fully help at this stage: I need to install all drivers, for both v6 and v7, for a given kernel version (can be kernel version or commit#)
I think install-wifi only install for the current running architecture.

I think I'll sed kernel= line within individual install.sh with actual kernel version, hopping pattern will not change in the future.

[TomSabom]

Hi,

Code: Select all

sudo install-wifi

always returns that there is no driver available for the current kernel 4.9.26.
Since the headline says driver for .... -> 4.xx.xx I'd expected the driver would be already available.
Is there a time schedule when the driver is updated and/or is it possible to use an older driver as well?
If it is possible how can I evaluate the archive name (tar.gz)?

Thanks for your help.

With kind regards,
Thomas

There are drivers available for Raspbian 4.9.26+ #996 or 4.9.26-v7+ #996 directly available via commands

Code: Select all

wget http://fars-robotics.net/8188eu-4.9.26-996.tar.gz
tar xzf 8188eu-4.9.26-996.tar.gz
./install.sh

tar xzf 8188eu-4.9.26-v7-996.tar.gz
./install.sh

What OS are you using? What is the output from command uname -a?

The filename format is described in the first post in this thread.

Hello all of you.
I'm having trouble installing these drivers.
First of all, I'm running a raspberry pi 3. I need 2 wifi modules for my project (it will, among other things, act as a wifi repeater)
using uname and all that, I downloaded and installed
8188eu-4.4.50-v7-970
the install script completed succesfully, I rebooted and it still doesnt show up. do I need to set up another wifi device?
what am I overlooking?

What wifi adapter do you have using the 8188eu driver? What other wifi will you be using as you say you need 2 wifi modules?

Please post the output of commands

Code: Select all

uname -a
ifconfig
lsusb
lsmod
cat /etc/modprobe.d/8188eu.conf

A wifi repeater using uname and all that? What on earth is all that supposed to be.

The USB id 2357:0109 is for the TP-Link TL-WN823N v2 and that uses the 8192eu driver. Details here https://wikidevi.com/wiki/TP-LINK_TL-WN823N_v2

You can remove the 8188eu driver you installed using commands

Code: Select all

sudo rm /lib/modules/4.4.50-v7+/kernel/drivers/net/wireless/8188eu.ko
sudo rm /etc/modprobe.d/8188eu.conf
sudo depmod -a

and install the 8192eu driver using commands

Code: Select all

wget http://fars-robotics.net/8192eu-4.4.50-v7-970.tar.gz
tar xzf 8192eu-4.4.50-v7-970.tar.gz
./install.sh

I cant believe I looked over that. Either way, thanks.
The internet often surprises me with its helpfulness.

Hi,

can't get the TL-WN725v2 (8188eu) working on latest 2017-08-16-raspbian-stretch-lite image. Experimenting all day. Latest steps are:
I put " install-wifi " in place. Running with -c rpi-update suggested a new firmware kernel revision = 4.9.43+ kernel build = #1026, so ran rpi-update. Then the install-wifi for latest driver. Reboot and no wifi.

Funny thing is that iwlist wlan0 scan gives a list of local seen wifi networks.

Also, found on other pages, the command
wpa_supplicant -B -i wlan0 -c /etc/wpa_supplicant/example.conf -D wext &
gets the adapter going too, even a working connection with the original image and original 8188eu.ko driver on it.

So I'm not sure where to go now. The image driver can connect with some tric, and the latest 4.9.43-1026 driver needs this trick, doesn't want to work simply with reboot.

I'm trying to upgrade some old installs which I did not upgrade for some years as every time the TL-WN725v2 wifi broke. Still no working recipe ...

Pi B, lsusb says ID 0bda:8179 Realtek RTL8188EUS (wrong?)
lsmod says cfg80211 size 525998 1 8188eu

There are a number of posts about wifi and Stretch. Seems like whoever setup Stretch likes to make things difficult for normal users. Seems like there's been significant changes to the network configuration that is causing real problems for many like you.

I am currently running Jessie with kernel 4.9.43-v7+ #1026, after running sudo rpi-update, and the WN725N is working OK with the 8188eu driver so as far as I can tell the driver is OK with kernel 4.9.43-v7+ #1026.

The problem with Stretch is the changes to the configuration so I would suggest you search the forum for posts about Stretch and wifi problems where solutions to the problem have been suggested.

I haven't tried Stretch yet as I am abroad so have limited facilities and internet access and will not be home until the beginning of October.

Sorry not to be more helpful.

Hello MrEngman,

I am on 4.9.43+ #1026 now. I had the same issues with Raspbian Jessie with PIXEL v4.9 2017-07-05 and Raspbian Stretch with desktop 4.9 2017-08-16, both used the Lite images without desktop. So I'm not sure if Stretch is the only baddie here.

I sudo rpi-updated to the latest and used install-wifi to get the latest 8188 driver.
With sudo nano /etc/rc.local I added the line:
wpa_supplicant -B -i wlan0 -c /etc/wpa_supplicant/example.conf -D wext &

I know the wext driver is said to be deprecated, but this gives a working system for now.

I will monitor this page if there will be a better solution.
