TL-WN823N v2 WLAN adapter could not find driver

[jszhao]

Hi there,
I bought a Tp-Link TL-WN823N USB wlan adapter. When I plug it into the computer, it is recognized as

ugen0.4: <Realtek DISK> at usbus0
umass0 on uhub0

Using usbconfig -d 0.4 dump_device_desc can get its `vid = 0x0bda` and `pid = 0xa192`. After using usb_modeswitch -KW -v 0x0bda -p 0xa192, it shows:

<Realtek 802.11n  WLAN Adapter> at usbus0

But it cannot bind to any `rtwn` drivers. I have loaded `rtwn`, `if_rtwn_usb`, and its firmware `rtwn-rtl8192eufw` into the kernel, yet the network card still cannot be recognized.

Does this mean there is no way to use it?

P.S.: The result of usbconfig -d 0.4 dump_device_desc of the wlan adapter is as follows. And it should be TL-WN823N V2. According to https://www.freebsd.org/releases/15.0R/hardware/, it is supported by FreeBSD 15.0. However, I could not drive it on FreeBSD 15.0-RELEASE.

it seems to be rtl8192fu based (linux kernel) and not supported i think

Using usbconfig -d 0.4 dump_device_desc can get its `vid = 0x0bda` and `pid = 0xa192`. After using usb_modeswitch -KW -v 0x0bda -p [B]0xa192[/B], it shows:

VendorID and ProductID should be 0x2357 0x0109

0x2357 0x0109 TP-Link TL-WN823N v2/v3 [Realtek RTL8192EU]

it should be TL-WN823N V2

In the dump_device_desc pasted in the end of my first post, the vid and pid of <Realtek 802.11n WLAN Adapter> is

idVendor = 0x2357
idProduct = 0x0135

It matches nothing, so it is not supported by FreeBSD?
