I purchased a TP-LINK TL-WN823N to use Aircrack-ng for research:

https://www.aircrack-ng.org/

However, when using airmon-ng I just see:

Interface   Chipset     Driver

wlo1        Intel 1030  iwlwifi - [phy0]

So I've used previous answers such as:

Problem with TP-Link TL-WN823N

DLink DWA 131 wireless adapter not working on ubuntu 15.10

Problem with TP-Link TL-WN823N

And I realised there was an issue with drivers, so I followed these answers.

I've tried to install from these repositories as explained in the answers (and also ppa:hanipouspilot/rtlwifi): github.com/pvaret/rtl8192cu-fixes github.com/Mange/rtl8192eu-linux-driver

So I removed others and I'm currently using Mange's rtle8192eu driver, the recommended driver for kernel 4.8.0-58-generic (recommended by Pilot6), which hasn't changed anything and also giving me this warning - as I've probably incorrectly removed others?:

> dkms status
rtl8192eu, 1.0, 4.8.0-58-generic, x86_64: installed (WARNING! Diff between built and installed module!)

So I'm a bit lost at the moment on what to do, upon using iwconfig, this is currently displayed:

Seems it is read as wlx8416f91d8fbc but still not found under airmon-ng interfaces.

My TL-WN823N currently has no green light flashing like you would usually expect and regardless of what I've tried, I cannot get it to work with Aircrack-ng. If someone could guide me through fixing this issue, I would much appreciate the help - I'm not an expert in Linux by any means but I've tried some existing solutions to no avail.

Update #1: Upon re-install of Mange's driver, I get this output: 
sudo dkms install rtl8192eu/1.0

Kernel preparation unnecessary for this kernel.  Skipping...

Building module:
cleaning build area....
'make' all KVER=4.8.0-58-generic....................

DKMS: build completed.

8192eu.ko:
Running module version sanity check.

Good news! Module version v4.4.1_17696.20160509_BTCOEX20160412-0042 for 8192eu.ko exactly matches what is already found in kernel 4.8.0-58-generic.
DKMS will not replace this module.
You may override by specifying --force.

depmod....

Backing up initrd.img-4.8.0-58-generic to /boot/initrd.img-4.8.0-58-generic.old-dkms

update-initramfs........

DKMS: install completed.

Update #2: I was able to fix the issue by firstly uninstalling the driver, then going into /lib/modules/4.8.0-58-generic/kernel/drivers/net/wireless and getting rid of 8192eu.ko (I just renamed it). This prevented the duplicate found in the log above. Then I reinstalled and the installation was normal. However, USB stick is still not working, but I am getting the following dkms status output (as opposed to before - see above):

rtl8192eu, 1.0, 4.8.0-58-generic, x86_64: installed

I just wanted to come back and answer my own question, just in case anyone else has this problem in future and finds this thread useful. I had a series of issues on Ubuntu 16.04 (as the host OS), Virtual Machines (Kali as Guest OS) using VirtualBox and MacOS Sierra.

Note: I had these issues using the TP-LINK TL-WN823N.

Drivers used

With the TP-LINK TL-WN823N the solution that worked simply, was installing Mange's driver which is recommended for Kernels 4.8+. Use uname -r to see which you are on. If you are below 4.8, you may benefit from installing Pilot6's driver (see next) or if you're 4.8+, Mange's driver seems to be the way to go.

See Pilot6's answer ("Problem with TP-LINK TL-WN823N" - included in my question) for help on installation for Mange's driver (he also has his own driver, which is recommended unless you're on a Kernel that is 4.8+ ). This specific question became quite over-bloated as I had incorrectly installed drivers and then had to remove them as well as any other files (see edits on question) that it had created. However, if you simply ensure you install Mange's driver there should be no issues.

Be wary of installing multiple drivers, this will not work. Uninstall the ones that are not required (see comments above to my question) and install the correct driver depending on your Kernel version.

MacOS installations

Furthermore, I wanted to share my advice on he TP-LINK TL-WN823N solution for MacOS users. I had issues finding any drivers at all for MacOS (I'm running Sierra), as it seems TP-LINK have removed all their drivers for this specific stick on their website. There's a simple solution for this, install the V2 driver designed for the TP-LINK TL-WN725N instead and this should work flawlessly after you have completed the installer. A restart may be necessary.

Virtual Machines

As for any installations on Virtual Machines, at least using VirtualBox. I found there to be issues in general with any USB devices being detected at all, which was a more general issue. To fix this, follow these steps:

  1. sudo apt-get install dkms

  2. sudo apt-get install gnome-system-tools

  3. sudo usermod -G vboxusers -a $USER

Where $USER is to be replaced by your username (found using whoami or echo $USER).

Once you've done this, restart your host OS and re-launch VirtualBox and it should be picking up. This is a separate issue to this question, but I originally thought it was also part of the same problem I had regarding this USB stick (software drivers) - but it isn't, to avoid confusion for future users with this issue.

Special thanks to Pilot6 and ravery for their help. They saved me tons of time undoing the mess that I had created due to my confusion due to installing incorrect drivers. If only TP-LINK had better support for their hardware to begin with.

I hope this helps.
