You know that TL-WN722N-V2 does not support monitor mode and packet inject? It doesn't. See this
And this for info why

In simple words, v2 has RealTek Chipset which does NOT support Monitor Mode and Packet Injection but v1 has Atheros Chipset which does support Monitor Mode and Packet Injection, I know its ****ing sad that they are randomly shipping v1 and v2, it's no better than any normal adaptor for connecting to the internet. Sorry, the best you could do is ask for a return or save it for later.
