wl18xx cannot connect to secured AP

Hello,

I have a board with IMX6Q Soc and running Linux with 3.10.62 kernel version.

I integrated the R8.6 version from the TI wifi driver using backporting guide.

I can connect to WI-FI AP's that are un-secured and all is okay.

When I try to connect to a secured AP, I get the following error:

nl80211: set_key failed; err=-2 No such file or directory)
wlan0: WPA: Failed to set PTK to the driver (alg=3 keylen=16 bssid=80:00:0b:3a:ab:83)

I'm using TI's wpa_supplicant binary with the following command:

~# wpa_supplicant -i wlan0 -c wpa_supplicant.conf -dd

The wpa_supplicant.conf file looks like this:

network={
ssid="test_AP"
key_mgmt=WPA-PSK
pairwise=CCMP
group=CCMP
psk="testpassword"
}

I saw that other similar threads were solved by upgrading from an older version to the R8.6, but I already have the newest version.

I would like some help to fix this problem.

Thank you!

Hi,

Can you share the "-dd" logs?
Also, please refer to: processors.wiki.ti.com/.../Connect_to_Secure_AP_using_WPA_Supplicant and confirm the steps.

Regards,
Gigi Joseph.

Hello Joseph,

I attached here the logs with "-dd".

I also tried to connect with wpa_cli as in the linked you showed me and the same error appears.

Thank you!

Hi,

Do you see this AP if you do a normal scan (iw wlan0 scan)?

The reason is, from your wpa_supplicant, the AP you are trying to connect is "Test_AP". But it doesn't show up in your logs.
The only ones that are discovered are:

Line 1037: wlan0: 0: 80:00:0b:3a:ab:83 ssid='otp-spanceac-l2' wpa_ie_len=0 rsn_ie_len=20 caps=0x411 level=-91 wps
Line 1039: wlan0: 1: 00:15:00:d1:fa:1a ssid='IvI' wpa_ie_len=0 rsn_ie_len=20 caps=0x411 level=-92 wps
Line 1041: wlan0: 2: ac:a3:1e:e3:24:60 ssid='wind' wpa_ie_len=0 rsn_ie_len=20 caps=0x1431 level=-95
Line 1043: wlan0: 3: ac:a3:1e:e3:24:61 ssid='WR-guest' wpa_ie_len=0 rsn_ie_len=0 caps=0x1421 level=-96

Hi Jospeh,

The log you are seeing is from when I try to connect to "otp-spanceac-l2" AP.

The wpa_supplicant.conf that I posted in my initial comment was as an example.

The actual wpa_supplicant.conf file that I was using when I collected the logs is this one:

network={
ssid="otp-spanceac-l2"
key_mgmt=WPA-PSK
pairwise=CCMP
group=CCMP
psk="1VCaCTgS"
}

Thank you!

Hi Sebastian,

Sorry for the late reply!
I tried it on my setup, and it seems to work fine for me.

Can you confirm if you have enabled all the kernel configs as mentioned in processors.wiki.ti.com/.../WL18xx_Platform_Integration_Guide

Specifically the CONFIG_CRYPTO_XXXXXXX ones...

Regards,
Gigi Joseph.

HI Joseph,

It seems that I was missing these config options from the kernel:
CONFIG_CRYPTO_CCM=y
CONFIG_CRYPTO_GCM=y

Now I can connect to a secured WIFI and it's ok.

Thank you!
