• Adapter is TP Link trademark
• There is a fancy mysterious alphanumeric identifier in front of box, like you should not miss it : TL-WN823N
• Debian has a page dedicated to WIFI https://wiki.debian.org/WiFi
• I goolged and found https://unix.stackexchange.com/questions/166408/install-usb-wifi-tl-wn823n-on-debian
• And TP Link website has a firmware webpage dedicated to TL-WN823N https://www.tp-link.com/fr/support/download/tl-wn823n/ : on this page, I have to choose a version, and the webpage tells me I have to find on the shop package, which version of the firmware I need (its like close to a bar code)
• I need version 3.0
• And there is an installation guide : https://static.tp-link.com/2018/201812/20181207/Installation%20Guide%20for%20Linux.pdf
• And start the ops :

curl -LO "https://static.tp-link.com/2018/201812/20181207/Installation%20Guide%20for%20Linux.pdf"
# And ok, there are multiple options, closest to debian is ubuntu, but they also have... Kali ...?/!....
# -- nevermind 'ill try Ubuntu isntruction, adapted with no apt repo

• Then in /etc/NetworkManager/NetworkManager.conf :

[device]
wifi.scan-rand-mac-address=no

• Then to bring network link up :

# ip a
# sudo iw dev
# sudo ip link set wlp2s0 up

• Scan for available networks and get network details (If you already know your wifi network id/ESSID, you can skip this step) :

$ su -l
# iwlist scan

Load the driver as LSB Module

Load the DriverHere we show the 88x2bu.ko wireless driver loading process as an example.

• Run the following command to load the driver :

$ sudo cp 88x2bu.ko /lib/modules/[kernel version]/kernel/drivers/net/wireless/
$ sudo depmod -a 
$ sudo modprobe 88x2bu

• Or directly use insmod to load the driver :

$ sudo insmod 88x2bu.ko

• After loading the driver, run the following command to check if the driver is successfully loaded :

  lsmod
