I followed the instructions on that post, but my dongle seems not to work: Tp-Link WN821N (2357:0107) not working with Ubuntu 16.04

After installing the RTL8192EU driver, it finally detects the dongle and shows some information when typing iwconfig in the console (see below). but even then, the dongle is not showing anywhere else and I can not search for wireless networks.

anthonidas@AnthoUnixSurface:~$ lsusb

Does anyone have an idea what I did wrong? Is the TP-Link WN821N not compatible with Linux?

Edit this is the output of dkms status:

anthonidas@AnthoUnixSurface:~$ dkms status

EDIT2 here we go:

anthonidas@AnthoUnixSurface:~$ cat /etc/network/interfaces

Ok, I finally found the solution in the Kali-Linux Forum and it works for Ubuntu too.

What I did first was to uninstall your driver and download that one: https://github.com/Mange/rtl8192eu-linux-driver, but in fact I did not check if it is the same... so I am pretty sure that it would have worked with your driver aswell.

Anyway the final solution was to blacklist the CU-Driver!!

So for everyone having the same issue, do the following:

1. Download the rtl8192eu driver from the above link or from pilot's repo
2. Install it with make and sudo make install
3. Blacklist the rtl8192cu driver
   in terminal type: sudo nano /etc/modprobe.d/blacklist.conf
   add a new line with that --> blacklist rtl8192cu
   save the file
4. Reboot and AFTERWARDS plug your dongle in
5. The post in kali-linux's forum said, that for that guy it hadn't worked on the first try. In that case he suggested just to repeat the installation several times.

I don't take any credits, I just copied NL2016's answer here because it was helpful for me and it could be for others too... If you want to read his discussion, here it is: https://forums.kali.org/showthread.php?34548-TP-Link-TL-WN821N-Wifi-Adaptor-no-interface&p=67560&viewfull=1#post67560
