I have a wireless TP-Link WN822N v4 usb wireless adapter I want to use in Ubuntu. Drivers rtl8192eu are not found in Lib/Modules after make install.

Description: Ubuntu 18.04.1 LTS
Release: 18.04
Codename: bionic
$ uname -r 4.15.0-29-generic

I followed the instructions from an older post on this forum: How to install TP link WN822N on Ubuntu?

git clone https://github.com/jeremyb31/rtl8192eu-linux-driver
cd rtl8192eu-linux-driver
sudo make
sudo make install
sudo modprobe 8192eu

Everything ran successfully, except for the last command: sudo modprobe 8192eu.

modprobe: FATAL: Module 8192eu not found in directory /lib/modules/4.15.0-29-generic

All the 8192eu drivers are in my Home directory after the cd and make install . Here are 2 examples:

CC      /home/tomx2/rtl8192eu-linux-driver/8192eu.mod.o
LD [M]  /home/tomx2/rtl8192eu-linux-driver/8192eu.ko
make[1]: Leaving directory '/usr/src/linux-headers-4.15.0-29-generic'

I am unable to to copy/paste 8192eu drivers in Lib/Modules, without permission.

How can I get 8192eu drivers into Lib/Modules?

I am a new Ubuntu user. Any help will be appreciated.

@Jeremy31 As per your request lsusb is listed below. I can connect to my hotspot, but I'm not sure the the rtl8192eu.ko driver is being used. I suspect a default driver is being accessed. Getting only 1 band during connection. Very slow. I do not see 8192eu.ko driver in Lib/Module (see listing below). The wireless usb adapter TP-Link WN822N does not light up/blink but will disconect from hotspot when I unplug.

Is there a way I can get rtl8192eu driver to be used?

Thanks.

Edited 08/10/2018 New info. This is the OP:

I was able to resolve the “Modprobe Fatal Module 8192eu not found in Lib/Modules” error. Needed to install app: libelf-dev. This allowed a clean Make/Install. When I launch the internet using TL-link Wn822N as my USB interface, the connection is extremely slow.

Only one Band and the wireless interface does not light up. Below are 2 output (linux) commands for your review. One shows 8192eu driver the other shows rtlxxxu.

(Q) Do I need to Modprobe another driver? Can anybody help?

sudo lsmod | grep cfg

sudo lshw -c network

  • Please edit the question to include results for lsusb Actually just try a reboot – Jeremy31 Aug 5 at 12:49
  • Check lsmod | grep cfg and see what modules it shows – Jeremy31 Aug 6 at 10:05

Solution is there. Whereas announced as DEPRECATED, the method id still valid. Do not forget to blacklist the old driver(last step of the howto) which was most probably my case.
