Connecting to WPA(2) using wpa_supplicant and atheros chipset -- ubuntu

[Alvin Mites]

Been hacking at this all day, it's also the 3rd card so I got a few more already invested but not giving up this time

I have a TP LINK TL-WN722N with atheros chipset AR9271

I have a beaglebone black running ubuntu 13.04 arm

I've followed upwards of a dozen different tutorials with a number of links below to different references

I can connect to a wireless router with security disabled using iwconfig

I cannot connect to anything with WPA 1 or 2

wpa_supplicant.conf looks like

network={

        proto=WPA2

        key_mgmt=WPA-PSK

        pairwise=CCMP TKIP

        group=CCMP TKIP

        ssid="MYSSID"

        #psk="supersecretpassword"

        psk=f2b34bb6b0e3ec1747325fac94ce0476a30911e08cf582df472d5df76e51dcad

}

so when I run

# wpa_supplicant -P /var/run/wpa_supplicant.wlan0.pid -i wlan0 -Dwext -c /etc/wpa_supplicant/wpa_supplicant.conf

I get

ioctl[SIOCSIWENCODEEXT]: Invalid argument

ioctl[SIOCSIWENCODEEXT]: Invalid argument

ioctl[SIOCSIWSCAN]: Device or resource busy

wlan0: Failed to initiate AP scan

wlan0: Trying to associate with 00:00:00:00:00:00 (SSID='MYSSID' freq=2437 MHz)

ioctl[SIOCSIWFREQ]: Device or resource busy

ioctl[SIOCSIWESSID]: Device or resource busy

wlan0: Association request to the driver failed

wlan0: Associated with 00:00:00:00:00:00

wlan0: WPA: Invalid EAPOL-Key MIC when using TPTK - ignoring TPTK

wlan0: WPA: Could not verify EAPOL-Key MIC - dropping packet

wlan0: Authentication with 00:00:00:00:00:00 timed out.

any ideas?

tried a number of variations of the above, can copy & paste from history if it will be useful

Hi Alvin,

this was working

http://askubuntu.com/questions/138472/how-do-i-connect-to-a-wpa-wifi-network-using-the-command-line

but if you would like to use wlan as start your interface and wpa_supplicant.conf must be ok.
