Description Amith 2017-08-12 05:22:45 UTC 
This is a TP-LINK product but uses the RTL8192 chipset inside, so urtwn driver should work.

Followed all the steps given in this link, but can't use the TP-LINK USB wifi

Possible solution:

Adding device VID:PID (2357:0109) to the urtwn driver

1. Add the vendor and product to /sys/dev/usb/usbdevs
 (+) vendor TPLINK 0x2357 tplink
 (+) product TPLINK RTL8192CU  0x0109

2. Add the vid:pid to /sys/dev/urtwn/if_urtwn.c
 (+) URTWN_DEV(TPLINK, RTL8192CU)

Hi,

The urtwn(4) driver does not support this device; support was added only in 12.0-CURRENT (r312680).

Support for RTL8192EU chipset is in CURRENT since base r312680 (and included into 12.0-RELEASE); the USB id for TP-Link TL-WN823N v2 was added a bit earlier - in base r308460.
