Hi anonmd,

Sorry for not responding sooner.

The drivers I compile are for use with Raspbian. From the output of command uname -a you show you are not using Raspbian so unfortunately I don't have drivers for the OS you are using.

Hi Mr.Engman,

1st) big thank you for providing these drivers

2nd) just wanted to let you know that your "install-wifi" fails with my noname USB-wifi:

Code: Select all

Bus 001 Device 004: ID 0bda:818b Realtek Semiconductor Corp.
it gets detected as needing "8812au" drivers but apparently works only with "8192eu"

I can't see anything wrong with the script. On my various Pi;s USB ID 0bda:818b is detected as using the 8192eu driver as expected.

Can you post the complete output of your lsusb command as what you are seeing would indicate you also have a device connected using a USB ID in the 8812au driver.

To force the 8192eu driver to load you can use the command ./install-wifi 8192eu.

as it is the only USB device I connected, the lsusb looks like this:

Really odd. Looks like the script has been corrupted somehow. Why it should think " Bus 001 Device 002: ID 0424:9512 Standard Microsystems Corp. LAN9500 Ethernet 10/100 Adapter / SMSC9512/9514 Hub" is a wifi module I don't know as the script checks the output from the lsusb command against a list of USB ID's for each type of wifi to determine the driver to load and the USB ID 0424:9512 is not in any of the lists of wifi adapters.

I would suggest you download the script again

Code: Select all

wget https://dl.dropboxusercontent.com/u/80256631/install-wifi.tar.gz
tar xzf install-wifi.tar.gz
and see how it then behaves. The latest version of the script also includes some additional USB ID's for newer wifi adapters.

EDIT: you say depmod -a adds a line ... - where?

I just don't understand why you are having this problem, however I have made an additional change, so you could try that.

I use this script on 5 different Pi's I am running at the moment and don't have any problems and there are other people using it as well and nobody else has reported any problems.

Please make sure you delete the old version of install-wifi and the install-wifi.tar.gz file before downloading a new version.

This is what I see downloading the 8192eu driver.

Code: Select all

[email protected]:~ $ ./install-wifi

Your current kernel revision = 4.4.30-v7+
Your current kernel build    = #919

Your current kernel revision = 4.4.30+
Your current kernel build    = #919

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

Your wifi module is unrecognised.

**** Unable to identify your wifi module ****

The script only works for wifi modules using the rtl8188eu, rtl8192eu, rtl8812au, mt7601, mt7610 and mt7612 drivers.

Looking for your wifi module the script detected the following USB devices:-

Bus 001 Device 002: ID 0424:9514 Standard Microsystems Corp.
Bus 001 Device 001: ID 1d6b:0002 Linux Foundation 2.0 root hub
Bus 001 Device 003: ID 0424:ec00 Standard Microsystems Corp.
Bus 001 Device 005: ID 058f:6364 Alcor Micro Corp. AU6477 Card Reader Controller

If you are certain your module uses one of the drivers the script installs check the output of command
'lsusb' shows your wifi module. If lsusb shows your wifi module try running the script again. If the
script fails to detect your wifi module again the driver may need updating to add your module USB id.

If lsusb does not show your wifi module you will need to resolve that issue before the script can be
used to install the driver you need.

Hi,
thank you for your patience. I see you picked up my findings and made a new version.
(seen my latest edit using & instead of / for extending regexp to next line?)

maybe it all is related to my version of
grep ((GNU grep) 2.20) or
bash (GNU bash, version 4.3.30(1)-release (arm-unknown-linux-gnueabihf)) or
image (Linux raspberrypi 4.4.26+ #915 Thu Oct 20 17:02:14 BST 2016 armv6l GNU/Linux) or ....

last but not least it is working now.

thanks,

I didn't see your edit until now. Don't really understand it but then I've always had problems figuring out how to use grep.

Some of the Pis I use have the same versions of grep and bash as you are using and I haven't see any problems using the script on those ones.

Really weird problem. I can create the error you got but only by editing the original v5 version. I guess somehow it's down to trying to use multiple lines to list the USB IDs and the error is occurring due to detecting the line in lsusb incorrectly due to an issue with grep, but why you see the problem and I don't I just can't figure out. Putting all the USB IDs on a single line gets rid of the issue but I then find editing the file to add new USB IDs when necessary is a real pain.

Anyway, good to hear it's now working for you.

If you read the posts you will see that there is a script that will download and install the driver if I have compiled it and it is available.

Download and install the script using commands

Code: Select all

wget https://dl.dropboxusercontent.com/u/80256631/install-wifi.tar.gz
tar xzf install-wifi.tar.gz
Now run command ./install-wifi -h to see the info on how to use the script.

Please supply details on the OS you are using. e.g. output of command uname -a would help.

You could try and reboot.

Dear Mr Engman,

I am also using a device using RTL8192EU driver (according to what I found), it is TL-WN823N.
I am very impressed by the solution you've provided, as it is wayyyy easier than anything I have seen until now, looking for a solution to this problem.

Nonetheless, I have a little issue :

I am using a raspberry pi 2B, and when I type uname -a, I get :

Therefore I tried :
wget https://dl.dropboxusercontent.com/u/802 ... 930.tar.gz

unfortunately, it doesn't work, it seems there is no file with this name. The answer is as follows:

Thank you very much,

Woops ;)

Thank you soo much!!

It works perfectly now ! You're my hero!

I wish this solution would be available for more drivers, as some of the dongles I have do not work on the RPi, and I can find no solution for these.
I have tried adapting the url to other chipsets, but it doesn't work (for instance, for TP-Link Archer T2U, using chipset MediaTek MT7610U).
If you know anywhere I could find the same kind of document as yours, and upload it using the same technique, that'd be great!

Thanks again !

Good to hear. Glad to be able to help.

And for your Archer T2U I also have drivers for the 8188eu, 8812au/8821au, MT7610U and MT7612U wifi modules. Same name format as the 8192eu driver except change 8192eu to 8188eu, 8812au, mt7610 or mt7612 as required.

Just a warning. I have a TP-Link Archer T2U running on a Pi 3B but the performance it not too good and it was a pain getting to connect the very first time, however the connection now appears stable. However, rebooting or powering off and on now and it connects without problems, just very difficult getting the wifi to connect the first time. Basically I think the code needs a load of updating but my knowledge of C is almost nil so I am unable to correct the problems myself.

MrEngman, thanks so much for this! I'm really happy that I didn't need to compile these myself on my early model B, like I did with some other wireless drivers.

Two quick questions though:
  • Where can I find the source code for your modified driver version?
  • Would you (or anyone else) be interested in me possibly packaging all of these as debian packages, and setting up a repo of them? For those of us running Raspbian, that should make installation as simple as adding the repo and apt-get'ing the package.
Thanks,
Jason

Im pretty sure I downloaded the correct one. But I get errors. I already reinstalled the Pixel and so on.

The error is:

Code: Select all

do cp 8192eu.conf /etc/modprobe.d/
Folder not found
sudo install -p -m 644 8192eu.ko /lib/modules/4.4.34+/....
Folder not found
Im sorry that I could not provide the real error message. But I have no ssh and have to type it while running to my TV to read from it.


Thank you very much!

I m'using a TL-WN823N V2 with RTL8192EU driver.I have installed your driver and everything work perfectly.
I buyed this dongle to turn my RPI in an access point and I could do this using the stock hostapd.
The problem is that the connected devices are only detecting 65 Mbps instead 300 Mbps.

this in my RPI configuration

Any suggestion to improve the bit rate??

Thank you very much,

I have very little knowledge of how the code works so how the bit rate is set I'm not really sure. I had a search around the internet and there are many others with the same issue but trying to improve the bit rate looks to be something of a problem.

I have found on my Pi with 8192eu wifi, an Approx APPUSB300NAV2, I get different bit rates depending on the access point I'm connected to. I have a Devolo Dlan 200 powerline access point and connecting to that I get a bit rate of 300Mb/s but connecting to a Netgear WAC120 access point which I think should give better performance and has 2.4Ghz and 5Ghz modes only gets a bit rate of 144.4Mb/s.

I see a similar issue with the TP-Link TL-WN725N using the 8188eu driver which has a bit rate of 150Mb/s connected to the Devolo DLan 200 while only 72.2Mb/s connected to the Netgear WAC120.

Strange thing is the Devolo is about 8M from my Pi's but the WAC120 is less than 2M from them.

On the 5GHz band I have 3 wifi modules which all get different bit rates. Two use the same driver, 8812au, and I get 867 Mb/s with an Asus USB-AC56 with a Pi B+, and 434 Mb/s with an Edimax EW-7811UTC on a Pi 2B. The other using the mt7610u driver with a TP-Link Archer T2U only gets 135 Mb/s.

Sorry I can't help but It looks like, to some extent, that it may depend on the access point and maybe it's settings and also the wifi being used. In your case where you are using the wifi as an access point the bitrate may be due to the wifi module you are using or maybe some of the AP settings, but just guessing.

Is that a Pi Zero?

What OS are you using? What does the command uname -rv show? I need this info to see if one of the drivers I have compiled will work with your Pi.

Thanks the fast response !
Yea sorry. It's a zero.
The result is:
4.4.34+ #930 armv61

I'm pretty sure I choose the correct version tho ...
