Realtek RTL8192EU ID 0BDA:818B

I've managed to update the 8192eu drivers I compile so they are now available for 4.1.17(-v7)+ and 4.1.18(-v7)+.

Using my standard naming format you can download and install using

wget https://dl.dropboxusercontent.com/u/80256631/8192eu-kernel-build.tar.gz
tar xzf 8192eu-kernel-build.tar.gz
./install.sh

replacing kernel and build with the values from the command uname -a.

As an example for a Pi 2 B using raspbian 4.1.18-v7+ #845 use commands

wget https://dl.dropboxusercontent.com/u/80256631/8192eu-4.1.18-v7-845.tar.gz
tar xzf 8192eu-4.1.18-v7-845.tar.gz
./install.sh

For the Pi A/A+/B/B+ the kernel version will not have -v7 like

wget https://dl.dropboxusercontent.com/u/80256631/8192eu-4.1.18-845.tar.gz
tar xzf 8192eu-4.1.18-845.tar.gz
./install.sh

When i try to download the file it returns that file is not found.What should i do?

That is a rather old post you are quoting. If you look at newer posts you will see things have changed.

The simplest way to install my wifi drivers now is to use my install-wifi script which determines the wifi adapter you use and the kernel version you have and then should automatically download and install the right version of the driver you need. You can download and install the script using commands

Code: Select all

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

After it is installed to see info on how to use it use command

Code: Select all

sudo install-wifi -h

To download the driver to your current kernel version you should just need to use command

Code: Select all

sudo install-wifi

I have an RPi3 with the latest (V0.17.0) Openplotter loaded.

I'm trying to set up a USB wifi dongle and have hit the problem that is the subject of this thread.

I have just tried the instructions above and it fails. The first 2 lines seem to work OK (a new file has appeared in /usr/bin/install-wifi) but it fails when I try sudo install-wifi with the message

Raspberry Pi wifi driver installer by MrEngman.
*** Performing self-update
!!! Failed to download update for install-wifi!
!!! Make sure you have ca-certificates installed and that the time is set correctly

I have checked that ca-certificates are available and the RPi3 time is correct.

For info the information for the dongle I am trying to install is as follows -

[email protected]:~ $ lsusb
Bus 001 Device 007: ID 0bda:818b Realtek Semiconductor Corp.

and the linux version is

[email protected]:~ $ uname -a
Linux openplotter 4.9.35-v7+ #1014 SMP Fri Jun 30 14:47:43 BST 2017 armv7l GNU/Linux

Is tyhere a problem with this combination or am I doing doing something wrong?

Thanks in advance for any help you can give.

[MrEngman]

If you have ca-certificates installed and the time is right then I'm not sure why you should be having problems.

Have you set the timezone? sudo raspi-config, 4 Localisation Options, I2 Change Timezone.

[Playtime]

Thanks for your reply.
The time was correct but the TimeZone was set to Other. I have now set the TimeZone to London and tried again but it still fails after about 3 minutes with the same message.
I have also rebooted the Pi and tried again with the same result.
It looks as though it is timing out waiting for a file from your server.
Are you sure this combination of dongle chip and Linux version should work?

Really odd. I have no problems using the script and downloading wifi drivers, including for the 8192eu.

Can you access the web site at http://downloads.fars-robotics.net?

Hello! I have a RPi3 and I'm trying to set wi-fi adapter Realtek RTL8192EU chipset (0bda:818b).
My uname -a output:

Linux raspberrypi 4.9.73-v7+ #1072 SMP Sun Dec 31 19:37:41 GMT 2017 armv7l GNU/Linux

I followed instructions and successfully downloaded install-wifi script. But when I run sudo install-wifi I get the error message:

!!! Failed to download update for install-wifi!
!!! Make sure you have ca-certificates installed and that the time is set correctly

I checked ca-certificates and everything is up-to-date. Timezone is set to Poland/Warsaw.

My problem looks similar to Playtime's. I can't access the website at http://downloads.fars-robotics.net.

Do you have any suggestions?

Edit.
I checked again. Right now the website is working fine and I managed to download the driver and turn on the adapter.
Thanks!

[Playtime]

No, but please note when I click on the link in your post above it tries to access /downloads.fars-robotics.net/, on the raspberrypi.org/forums/ site which may not be what you intended.

I would add that this was from a Windows 10 machine not from the RPi. However, I don't think that is the problem.

Can you give me the full www address that you want me to test? I will then try that from the Pi.

Thanks for continuing to help solve this with me.

Sorry about that. Don't know how the link ended up like that but I have now edited it and it should be correct now. Seems to work OK for me on my Win7 laptop.

[Playtime]

Brilliant. Whatever you did has solved the problem; the driver has loaded and works correctly.

Thank you for your assistance.

Thanks for the update.

The problem turned out to be something rather stupid. I set up a Pi on my network to act as a server as the web space supplied by my ISP that I was previously using was running out of memory and I didn't update the firewall to allow the Pi to be accessed from the internet. Updating the firewall seems to have now fixed it as you have now been able to update your driver.

[AndersM]

I just upgraded the PI and had forgotten about the Wi-fi driver problem. If I had remembered I should have avoided the upgrade...
Now running install-wifi I get:

Code: Select all

Your current kernel revision = 4.9.80-v7+
Your current kernel build    = #1098

Checking for a wifi module to determine the driver to install.

Your wifi module is Bus 001 Device 004: ID 0bda:818b Realtek Semiconductor Corp. 

And it uses the 8192eu driver.

Checking for a 8192eu wifi driver module for your current kernel.
A driver does not yet exist for this update.

Looking in the driver list there seems to be drivers for very similar versions. Can I use any of these? And if how?

Unfortunately the data for kernel 4.9.80-v7+ #1098 is not available so I wasn't able to compile the driver for that specific version.

I have, however, made a new SD card with that kernel and the driver for kernel 4.8.80-v7+ #1092 appears to load and run OK.

You can download and install that driver using commands

Code: Select all

wget http://downloads.fars-robotics.net/wifi-drivers/8192eu-drivers/8192eu-4.9.80-v7-1092.tar.gz
tar xzf 8192eu-4.9.80-v7-1092.tar.gz
./install.sh

You can then load the driver with command

Code: Select all

sudo modprobe 8192eu

and after a short time the wifi should start up.

Thanks!

[inafunex]

Thanks a lot! ,
the install-wifi script works great for me. I try with two diferents realtek adapters and works fine.

greetings!

Any chance you have a driver for Stretch:
Linux raspberrypi 4.9.80+ #1098 Fri Mar 9 18:51:28 GMT 2018 armv6l GNU/Linux

TIA

Yes. Install the script as detailed in the post before yours and then run the script and it will automatically determine the driver version you need and install it.

I had to create an account to thank you, MrEngman. Thank you very much! I spent quite some time tonight trying to install the drivers for a dongle with a Realtek chip on a bunch of Raspberry Pi 2's before I found this thread. First, when I tried to use the Dropbox links earlier in the thread and just got 404 errors, I was afraid I was too late. But then I read on, and discovered that not only did you stick around helping everyone with this problem, you even wrote a utility for us that automates the whole process. install-wifi worked perfectly from the first command and has with absolute certainty saved me (and lots of other people) many hours of trial and error.

Hats off.

[tanny123]

Thank you Mr Engman, I have tried for a long time for the usb wifi adapter to work on my raspberry pi, thank you very much!

[mkiami]

Hello MrEngman, thanks for putting in place such a useful installer script.

However, could you please explain how the binaries have been compiled for each driver / kernel? From a security point of view, I would like to compile the .ko file myself from source.

[mkiami]

Could anyone please share how the binaries have been compiled?

Thanks!
