hello ! where to buy TP-LINK TL-WN722N VERSION 1 ? i coudn't find it in market / online stores. Only version 2 available in market.
In case you have bought TP-LINK TL-WN722N VERSION 2 and you are facing the similar issue that it can not get into monitor mode , you may have a fix to it. All you need to do is install this kernel [ https://github.com/mfruba/kernel ] and once you do it , you will be able to enter monitor mode [
# iwconfig wlan0 mode Monitor
V1 is a very old device and not easily found on the market , a very decent alternative is Alfa devices which work fine with various InfoSec OS
