Hi,

So, many WiFi adapters are supported by default.
But from time to time, you can come across some, that aren't supported, I have been trying over 3 days to get my TP-LINK TL-WN821N v3.1 working. Finally I found a way thanks to enc0de and many guides

So, this should work on all Debian based systems (Ubuntu, BackTrack....)

1) Download Compat Wireless HERE (I suggest, to get the newest version)

2) Open up terminal and type:

Code:

tar -xf [package name, in my case: compat-wireless-2.6.33.tar.bz2 ]

3) Now type in terminal:

Code:

cd [package name, in my case: compat-wireless-2.6.33 ]

***MAKE SURE THERE IS NO ".tar.bz2"***

4) Type in terminal:

Code:

make

-- This can take over an hour!!!

5) Type in terminal:

Code:

make install

6) Type in terminal:

Code:

make unload

7) Reboot, simple way is typing in terminal:

Code:

reboot

8) Now all is done, check your card by typing in terminal:

Code:

airmon-ng

Few last words:

You can start monitoring by typing in terminal:

Code:

airmon-ng start wlan1

The number after "wlan" might be different in your case. Check it in "airmon-ng"

You can start your network by:

Code:

start-network

OR

Code:

/etc/init.d/networking start

Have a great day!!!
