hcxdumptool not working under TP-Link TL-WN823N v2/v3 [Realtek RTL8192EU]-driver doesn't support ioctl() SIOCSIWFREQ

[abidmaria]

Hello ,
I am trying to use hcxdumptool , but i am getting the below errors :

sudo hcxdumptool -i wlan0 -o dumpfile.pcapng --active_beacon --enable_status=15

`
initialization of hcxdumptool 6.2.7-17-g87fcd83 (depending on the capabilities of the device, this may take some time)...
interface is already in monitor mode, skipping ioctl(SIOCSIWMODE) and ioctl(SIOCSIFFLAGS) system calls
driver doesn't support ioctl() SIOCSIWFREQ
frequency test failed
warning: failed to init socket

terminating...
1 driver error encountered
usually this error is related to pselect() after SIGTERM has been received
ERRORs < 10 are related to a slow initialization and can be ignored

`

Note that my wireless adaptor support monitor and injection :

`
lo no wireless extensions.

eth0 no wireless extensions.

It looks like this driver depend on NETLINK and doesn't support some (or all) ioctl() calls required by hcxdumptool.
Please connect the device. If it is already connected, please disconnect and reconnect it.
Now stop all services that take access to the device. Please do not use airmon-ng or iw.

Than run the following commands and post the output:
$ hcxdumptool -v
$ hcxdumptool -I
$ hcxdumptool -i wlan0 --check_driver

Difference betweeen aircrack-ng and hcxdumptool:
aircrack use NETLINK and ioctl() system calls
while
hcxdumptool uso only ioctl() system calls. The reason why I don't use NETLINK is described here:

Some more information about WiFi drivers is here:
#234

[ZerBea]

To identify the driver, please comment the output of
$ hcxdumptool -I wlan0
I guess it's not a stock kernel driver.

Thank you for your feedback
as requested , below is the output :

I think we can close this report, because other drivers are working as expected.

[abidmaria]

Agree , so it's better to include them in the future (if possible) , thank you for your excellent support.

This is the git hub of rtl88XXau:
https://github.com/aircrack-ng/rtl8812au
You can report issues related to the driver there.

As mentioned before, the stock kernel driver
https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git/tree/drivers/net/wireless/realtek/rtl8xxxu?h=v6.0.9
e.g. for this Realtek device (TP-Link TL-WN821N)
$ lsusb

while the third party driver doesn't work.

There is no tx power on channel 14, because it is disable in my environment by crda.

Latest git head hcxdumptool should work now running this driver:
https://github.com/kimocoder/realtek_rtwifi
kimocoder/realtek_rtwifi#34

[ZerBea]

Can you please test hcxlabtool which use NL80211 and RTNETLINK instead of WIRELESS EXTENSIONS):
https://github.com/ZerBea/wifi_laboratory

$ make
$ ./hcxlabtool -I interfacename

Thanks.
