Hello @MrEngman

Thank you for your hard work keeping all of our wifi's running :-)

I have a problem with my TL-WN725 V3, trying to get it to work on my Raspberry Pi .

I'v run your install-wifi script, with the following result:

*** Raspberry Pi wifi driver installer by MrEngman.
*** Performing self-update
*** Relaunching after update

*** Raspberry Pi wifi driver installer by MrEngman.

Your current kernel revision = 5.10.38-v7+
Your current kernel build = #2

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

Your wifi module is Bus 001 Device 004: ID 0bda:8179 Realtek Semiconductor Corp. RTL8188EUS 802.11n Wireless Network Adapter

And it uses the 8188eu driver.

Your Pi revision number is a02082
You have a Pi 3B v1.2
Checking for a 8188eu wifi driver module for your current kernel.
A driver does not exist for this update.

I think my kernel version is too new ?

Can you help me ?

Thanks

Christian

Hi - allow me to answer my own post :-)

I just reinstalled the latest Raspberry pi image on my raspi.

Since it is now running a slightly older kernelversion (5.10.17-v7+), the install-wifi script works.

I now have working wifi on my raspi! Yeah :D

Thanks

Christian

There was a newly released Raspberry Pi kernel package, dated yesterday, for which there isn't yet an 8188eu module? I use that that module on my three zeros. I think the last module I used was "http://downloads.fars-robotics.net/wifi ... 414.tar.gz".

My zero W's got the update and their uname -a is now "Linux pi0w4 5.10.17+ #1421 Thu May 27 13:58:02 BST 2021 armv6l".

I appreciate you keeping up this whole process for so long, for the benefit of so many of us. I hope that you've got an automated process for this, which just hasn't yet caught up, and not that this is something you're aware of and I'm just annoyingly whining and nagging...

Hello @MrEngman

First I would like to thank you for your job on maintaning a drivers database for these wifi modules.

I would like to ask you to provide a driver for 5.10.17-v7+ #1421 kernel version as I tried to update my rapsberry pi (sudo apt-get update) but now it can't find the proper wifi driver for my wifi dongle.

Unfortunatelly sudo rpi-update is not an option as it uptades to 5.10.39-v7+ #1421 kernel version, which also does not have a wifi driver available.

Thanks again and best regards,

Pulsus

The desired driver file is there now. I downloaded and installed it and and my zeros are back in business. Thank you!

I just got this adapter. My Pi Zero W is on version is 5.10.46+ #1430 is it possible to use the 5.10.44-1429 drivers? If not, any ideas when the updated package will be released?

Same as mine with 5.10.52+ latest kernel. Cannot get the driver for my 8821CU.

Please update the wifi drivers.

Thanks a lot.

MrEngman,
Many thanks for making this resource available. On one of my hosts I was easily able to get the TP-Link TL-WN725N USB adapter working. On another one, not so much. It was running

Code: Select all

hbarta@meeker:/etc/network/interfaces.d $ uname -a
Linux meeker 4.19.97-v7+ #1294 SMP Thu Jan 30 13:15:58 GMT 2020 armv7l GNU/Linux
hbarta@meeker:~ $

And it was not obvious to me if I had the correct version downloaded, though I tried several. The install.sh script reported errors with directories and after fiddling with that a bit, I ran rpi-update which brought me to

Code: Select all

hbarta@meeker:~ $ uname -a
Linux meeker 5.10.52-v7+ #1440 SMP Tue Jul 27 09:54:13 BST 2021 armv7l GNU/Linux
hbarta@meeker:~ $

As others have reported, there is no version for that. I downloaded and unpacked 8188eu-5.10.49-v7-1436.tar.gz. After modifying the kernel variable to kernel=5.10.52-v7+ the script ran without error (the target directory for the module already existed.) However on subsequent boot the module does not load and in dmesg output I see

Code: Select all

[ 9.070067] cfg80211: Loading compiled-in X.509 certificates for regulatory database
[ 9.236371] cfg80211: Loaded X.509 cert 'sforshee: 00b28ddf47aef9cea7'
[ 9.339769] 8188eu: disagrees about version of symbol module_layout

Going back to the previous attempt (with 4.19.97 kernel) I saw errors that looked like

Code: Select all

sudo install -p -m 644 8188eu.ko /lib/modules/4.19.97-v7+/kernel/drivers/net/wireless
install: cannot create regular file '/lib/modules/4.19.97-v7+/kernel/drivers/net/wireless': No such file or directory
sudo depmod 4.19.97-v7+
depmod: ERROR: could not open directory /lib/modules/4.19.97-v7+: No such file or directory
depmod: FATAL: could not search modules: No such file or directory

I guess for now I keep the Ethernet cable in place.

best,
hank

For those who updated to a newer kernel than 5.10.49 for which there is currently no wifi driver available try this:

Code: Select all

sudo rpi-update dc6dc9bc6692d808fcce5ace9d6209d33d5afbac

This will revert to 5.10.49 and you can then reboot and reinstall the wifi-driver using the MrEngman script :)

Just had to do this on both of my Pi2 B+ as I didn't think to check before updating them. Doh!

Mr Engman, could you post (or point us to) the source code for the drivers, and also post the scripts you use to prepare them? Then we could attempt making them ourselves.

Mr Engman hasn't made any update to any driver since June 16th.

I found the source for my driver 8188eu with a trivial Google search - https://github.com/lwfinger/rtl8188eu.
It needs the kernel source tree so I downloaded that with rpi-source.

It's a pain having to build from source, but it works OK building it on my RPi1B that has the 8188EU dongle.

Well, I haven't done any of this before, but I'm game. I took notes as I went:

20210803 try to build 8188eu driver for the pi zeros' wifi dongles
NOTE: doing this on a pi zeroW for the pi zeros
sudo apt install rpi-source
sudo apt install libncurses5-dev
look at the documentation on rpi-source
https://github.com/RPi-Distro/rpi-sourc ... /README.md
man rpi-source
rpi-source -d ~/Documents -v
* works, takes quite a while *
NOTE: since I did this from within Documents, it created a link *there* just called "linux" to the new linux-blah-blah folder within Documents, guessing that the driver might be more accustomed to this being at ~, I moved the linux link to ~; it still points where it did ...

note: at the end of its process, rpi-source posts a link to
https://github.com/RPi-Distro/rpi-sourc ... /README.md
which has "Examples on how to build various modules"
one of which is TP-Link TL-WN725N version 2 lwfinger

which sounded like just what I wanted, so, I did what it said, I've copied that part of the web page below ...

https://github.com/RPi-Distro/rpi-sourc ... 2-lwfinger
TP-Link TL-WN725N version 2 lwfinger
Ref: http://tech.enekochan.com/2014/03/08/ne ... -raspbian/

$ uname -a

$ make all

(part above done on the zeroW)
(part below done on the zero, after copying the results of the build over)

$ sudo make install

$ sudo depmod

$ sudo modprobe 8188eu

$ lsmod (actually the output of this was edited for the web page - there was a lot more output when I did it)
Module Size Used by
8188eu 796381 0

That all SEEMED to work, except after rebooting, wireless doesn't work for me, all I can do is attach a USB ethernet adapter to get there.
Also, I noted that the 8188eu.ko file is SMALLER (907,324) than the last one MR. Engman built (1,477,248).
I'm not sure that this is the source he uses.

I tried this again, doing it all on the pi for which it's intended (a Pi zero). Again, it all seemed to work.

Yet, still, "no wireless interfaces found" .

Anyone have any ideas about what I can do, or what to check?

Have you run sudo modprobe 8188eu?

I'm looking for a 8188EU driver for kernel version 5.10.52+ #1440. I would like to use a Edimax EW-7811UN V2 nano adapter on an older Raspberry Pi. Are you able to provide one?

Build it yourself from source. It's not too difficult.

Install the new kernel and connect to your network with a cable.

sudo apt install git bc bison flex libssl-dev

Get a copy of rpi-source from https://github.com/RPi-Distro/rpi-source

git clone https://github.com/RPi-Distro/rpi-source
cd rpi-source
./rpi-source

That gets you the Linux kernel source tree and leaves it ready to build kernel modules (you'll need to boil a kettle while it's running, it's not quick on a RPi1B).

Get the driver source from https://github.com/lwfinger/rtl8188eu

git clone https://github.com/lwfinger/rtl8188eu
cd rtl8188eu
make
sudo make install
sudo modprobe 8188eu

Again you've got a chance to boil the kettle. If you make a pot of tea first time round, here's your chance to pour out the second cuppa.

To get DHCP either reboot or sudo systemctl restart dhcpcd5

Not sufficient.

It seems that restarting wpa_supplicant is what is required. I'll have to study the command line arguments and try to figure out why the default does not work.

thanks again.,

If I do ALL of the above-mentioned steps, see everything I'm doing in the modified script below

Code: Select all

#!/bin/bash
set -x
sudo /sbin/modprobe 8188eu
sudo /usr/bin/killall -v wpa_supplicant
sudo /sbin/ifconfig wlan0 192.168.0.101/24
sudo /sbin/ifconfig wlan0 up
sudo /sbin/wpa_supplicant -B -c/etc/wpa_supplicant/wpa_supplicant.conf -iwlan0 -Dnl80211,wext
sudo /sbin/ip link set wlan0 up
sudo /sbin/ip route add default via 192.168.0.1 dev wlan0 
sudo systemctl restart dhcpdc5
systemctl restart wpa_supplicant.service

It brings up the wireless. I can then disconnect the ethernet cable from the USB ethernet adapter, exit my ssh session, and reconnect to the pi over just the wireless.

But I don't want to be hard-coding the address, nor have to execute this script via cron on every reboot.

So what's really going on here? Everything relating to wireless was set up before and worked fine with the Mr. Engman supplied driver. Now, with this home-built version, not so much. Why isn't the existing wireless setup sufficient to reliably enable and bring up the wireless using the new driver?

Sorry if I misunderstood this script as a "solution" if it was just intended as a bit of diagnosis.
