TP-LINK TL-WN823N v2 device strange driver problems and not able to handshake

mcjames · Jun 24, 2020

Hello;
Under `FreeBSD 12.1-RELEASE FreeBSD 12.1-RELEASE r354233 GENERIC amd64`, I am trying to setup my WiFi network with my TP-Link WN823N usb dongle.

tplink wireless adapter TL-WN823N front25afd68f816cbc.jpg

according to dmesg and the WikiDevi website I am running a device with RTL8192EU chipset.

Code:

ugen7.2: <Realtek 802.11n NIC> at usbus7

rtwn0 on uhub0

rtwn0: <802.11n NIC > on usbus7

rtwn0: MAC/BB RTL8192EU, RF 6052 2T2R

wlan0: Ethernet address: d4:6e:0e:7f:51:67

and this is what I have in my /boot/loader.conf :

Code:

wlan_wep_load="YES"
wlan_ccmp_load="YES"
wlan_tkip_load="YES"
if_rtwn_usb_load="YES"
if_rtwn_pci_load="YES"
if_urtwn_load="YES"
wlan_wpa_load="YES"
wlan_wpa2_load="YES"
wlan_scan_ap_load="YES"

legal.realtek.license_ack=1

It seems that I can't get the device to be picked up during the boot time.
and ifconfig wlan0 create wlandev rtwn0 returns SIOCIFCREATE2: Device not configured.
detaching and reattaching the device bring wlan0 to ifconfig .
And it seems the USB device gets disconnected when I try to handshake with wpa_supplicant

wpa_supplicant from the packages and not the base system since it crashes at the beginning:

I had that same usb dongle and unfortunately it wasn't supported ☹
So I bought a TL-WN725N and have been using it since

mcjames · Jun 25, 2020

I doubt that it is not supported.
as I can see wlan0 in my ifconfig result and every time I connect the dongle I get :

C-like:

rtwn0: detached
ugen7.2: <Realtek 802.11n NIC> at usbus7
rtwn0 on uhub0
rtwn0: <802.11n NIC > on usbus7
rtwn0: MAC/BB RTL8192EU, RF 6052 2T2R
wlan0: Ethernet address: d4:6e:0e:7f:51:67

But there is something serously wrong with this driver as I can't do any handshake with any AP.

Last time I used a USB Wifi stick I had to load an additional module. wlan_amrr.ko
So try and load it and see if it helps.
kldload wlan-amrr

WN823N and bunch of other wireless USB adapter, reminds me of Winmodems (Softmodems). They didn't even install on Linux Mint.

sorry that was a typo
kldload wlan_amrr

This module should be built in the kernel but it is worth trying to load it.

mcjames · Jun 25, 2020

Well I tested this dongle on OpenBSD and all linux distros you could think of. Worked perfectly.

didn't help. but huge thanks. cause you share your knowledge here.

Zinnia · May 23, 2021

mcjames did you finally solve the problem?
I use the same TP-LINK TL-WN823N on freebsd 12.2 release and get the same problem.

Bogdan Vătavu · Nov 6, 2021

I know this is an old thread, but I see no reason for starting a new one since I get the same problem on 13.0 release. Any update would be very appreciated, since this dongle is my only way to connect to the internet. Thanks!

If not yet supported in a RELEASE, then please be aware of what's on the roadmap for this year and 2022.

Same problem here. Any solution ? The driver required seems to be available in the kernel by default. Depending on the /etc/rc.conf settings, the dongle disconnects if the parameter "SYNDHCP" or "DHCP" is given to ifconfig_wlan0.

grahamperrin · Jan 4, 2022

grep wlan0 /etc/rc.conf

What's reported?

covacat · Jan 4, 2022

i have a WN725N and works
performance is not great but good enough for my use (pi zero)
less than $10

it reports :

ifconfig_wlan0="WPA SYNCDHCP"

There is a video where a guy configure this dongle, so theoretically, it should be supported. The stranger thing is that some parameters work for some people and not for other ones.

You need something more like this in your /etc/rc.conf file:

Code:

wlans_rtwn0="wlan0"
ifconfig_wlan0="WPA SYNCDHCP"
ifconfig_wlan0_ipv6="inet6 accept_rtadv"
create_args_wlan0="country US"

Please try following this guide:

Chapter 34. Advanced Networking

Andriy · Jan 5, 2022

Please check its USB device descriptor with something like usbconfig -d ugen4.3 dump_device_desc where ugenX.Y should correspond to the device.

Andriy · Jan 5, 2022

To expand, problems like yours are sometimes caused by an incorrect firmware variant.
Are you sure that you have V2 version of the dongle?
It could be V3, for example.

riemannesco · Jan 5, 2022

Indeed it is the version 3 that I got. It should be the firmware so. Just have to wait for an update I guess.

So, can you share the usbconfig output?
Things don't happen by themselves if nothing is done.

P.S. According to some (not very reliable) sources V3 has RTL8192CU.

yes of course.
The following command line

usbconfig -d ugen2.2 dump_device_desc

gives me :

Some WiFi routers have a "tx power" setting with low, medium and high. Setting it to high could help.
