Hello,

I have a problem when configuring my TP-LINK USB Wifi driver (Model: TL-WN823N V3) for Slackware 13.1.

I followed the instruction manual, yet when I launched the command:

wpa_supplicant -Dwext -iwlan0 -c ./wpa_0_8.conf -B

Note that my kernel doesn't support 802.11 apparently.

It outputs an error at line 51: unknown global field 'config_methods=virtual_display virtual_push_button keypad'.

What is Wifi configuration, such as ssid, psk and so on?

Result of iwlist scanning:

Good. The wlan0 can receive AP beacon. The next step: you need to configure the wlan0.
Please refer the URL, https://wiki.alienbase.nl/doku.php?id=slackware:network.

What does "ioctl[SIOCSIWAP]: Operation not permitted" mean ?
I got this error while running the rc.inet1 script (but above all while executing the wpa_supplicant command).

> What does "ioctl[SIOCSIWAP]: Operation not permitted" mean ?
You need to use root user to run the rc.inet1 script.

I've already done it.

What is iwconfig output?

lo no wireless extensions.

eth0 no wireless extensions.

The iwconfig output is fine. Can you transfer anything between the wlan0 and AP?

Nothing.

Where do you get the error message, ioctl[SIOCSIWAP]: Operation not permitted?
Is there any error message in dmesg after boot-up? I assume you have rebooted the machine after the configuration is done.

I actually got this error message while running wpa_supplicant with a file called "wpa_0_8.conf" given in the driver's directory, as its installation manual told. As a matter of fact, the first fatal error I got is with a specific line of this config file, as mentionned in my first message, and it is when I commented this line that the ioctl error appeared.
Next, dmesg doesn't seem to output any error message albeit there is a ton of entries and I do not know which one to look at in order to check if it is OK.

In https://wiki.alienbase.nl/doku.php?id=slackware:network. the wpa_supplicant.conf is like the following. Does line 51 of your wpa_supplicant.conf has the setting, 'config_methods=virtual_display virtual_push_button keypad'?
