My usb wifi adapter is not working on my raspberry pi zero. PS: Im new to Linux.

The adapter is called "Realtek RLT8192EU 802.11n Network Adapter". The adapter works fine on windows 10 but not on Linux. According to the manual I have to install the drivers for it to work on linux. I tried this but I got some errors ->

Authentication requested [root] for make driver:
make ARCH=armv6l CROSS_COMPILE= -C /lib/modules/4.14.69+/build M=/home/pi/Downloads/wifi_driver/Driver/linux/driver/rtl8821AU_linux_v4.3.14_134 55.20150212_BTCOEX20150128-51 
modules make[1]: *** /lib/modules/4.14.69+/build: Ingen slik fil eller filkatalog.  
Stop.
Makefile:1551: recipe for target 'modules' failed
make: *** [modules] Error 2
##################################################
Compile make driver error: 2
Please check error Mesg

When I type "Mesg" this is the result:

is y

Here is the output when I type "lsusb":

Here is the output when I type "uname -a":

Linux raspberrypi 4.14.69+ #1141 Mon Sep 10 15:13:50 BST 2018 armv6l GNU/Linux

Here are the drivers I tried to install but that didn't work: Drivers (kjell.com). This is the website where I bought the usb adapter from aswell.

-Thanks :)

EDIT: I read somewhere that using a powered usb-hub could solve the problem. Considering my current usb-hub is kinda low-quality (cheap), would it be a good idea to buy a new one?

  • Next troubleshooting step would be "ip -s link" to check all you network devices – Jan Hus Sep 11 '18 at 18:43

    ip -s link only shows lo and eth0 – Jonas Sep 11 '18 at 18:44
  • Thus you verified what is already known - the OS does not recognize the adapter. But USB found it.Back to the driver .Just for drill - you did verify WiFi is enabled in raspi-config. – Jan Hus Sep 11 '18 at 18:49
  • "PS: Im new to Linux" ALWAYS run "sudo apt update upgrade "to make sure you are not fighting windmills. – Jan Hus Sep 11 '18 at 19:23
  • Hi, sorry for the late reply. I actually re-installed respbian. Now it looks different when I run the "lsusb" command. I edited the orignal post. When trying to enable wifi trough raspi-config I get the error "no interface found" and "There was an error running option N2 Wi-Fi" – Jonas Sep 11 '18 at 19:49

Here is how I got it working:

EDIT: I re-installed raspbian stretch. I skipped the updates and I am currently using 4.14.50+.

First I followed this tutorial: https://askubuntu.com/a/863433

But when I tried to run the "make" command I got an error:

make[1]: Entering directory `/usr/src/linux-rpi-3.6.y'
Makefile:564: /usr/src/linux-rpi-3.6.y/arch/armv6l/Makefile: No such file or directory

Executing these commands magically fixed that for me:

cd /usr/src/linux-rpi-3.6.y/arch/
sudo ln -s arm armv6l

When I tried to run the modprobe command I also got an error that my module was not found. I just had to reboot and now it finally works (I did not use the modprobe command).

  • for me, it was "ln -s arm armv7l", but did the trick. Thank you! – kkazakov Oct 7 '18 at 17:53
