TP-link TL-WN722N monitor mode

Have a nice day, dear friends!

4.14.10-1-ARCH 

I bought TP-link TL-WN722N adapter, and i want it to work in monitor mode.
But i dont know what is chipset (there are 3 different versions).
I have tried to determine it via "lsusb", but it is unnamed (DEVICE ID 2357), why?:

Bus 002 Device 001: ID 1d6b:0003 Linux Foundation 3.0 root hub
Bus 001 Device 005: ID 0bda:0129 Realtek Semiconductor Corp. RTS5129 Card Reader Controller
Bus 001 Device 004: ID 1bcf:28c0 Sunplus Innovation Technology Inc. 
Bus 001 Device 008: ID 2357:010c 
Bus 001 Device 002: ID 10c4:8105 Cygnal Integrated Products, Inc. 
Bus 001 Device 001: ID 1d6b:0002 Linux Foundation 2.0 root hub

The same when i open airmon-ng (this interface called extw):

[user@home]$ sudo airmon-ng 

PHY	Interface	Driver		Chipset
null	        extw		r8188eu		 
phy0	wlp1s0		ath10k_pci	Qualcomm Atheros QCA9377 802.11ac Wireless Network Adapter (rev 31)

Also i tried use this driver (https://github.com/mfruba/kernel), but when i stop this interface and then trying to change monitor mode - i have an error:

Error for wireless request "Set Mode" (8B06) :     SET failed on device extw ; Invalid argument.

May be i should use another driver? How can i change it ?
How can i run it in monitor mode? Thanks a lot!

Re: TP-link TL-WN722N monitor mode

The only driver for Realtek USB chips that might support monitor mode is the in-kernel rtl8xxxu driver. But that driver doesn't support 8188eu devices yet. The developer of the driver has a branch for 8188eu devices, you'd need to checkout that branch and build the kernel from it. Might be hard, depending on how much experience you have compiling your own kernel. This is the branch: https://git.kernel.org/pub/scm/linux/ke … xxu-8188eu.

I briefly looked at the code in there, can't find your 010c device, so even if you do build that kernel, your device might not work without some tinkering to add 010c somewhere where other 2357 devices are handled in the code.

ep4sh, I am in the exact same situation. Did you end up finding a solution?
