wpa_supplicant fails to set essid

Postby erjoalgo » 2015-08-07 02:37

I'm not able to use wpa_supplicant to set the essid and other parameters on the wireless interface.

Using -Dwext throws
Code: Select all
ioctl[SIOCSIWENCODEEXT]


Code: Select all
 $ sudo wpa_supplicant -B -i wlan0 -Dwext -c university_wpa
Successfully initialized wpa_supplicant
ioctl[SIOCSIWENCODEEXT]: Invalid argument
ioctl[SIOCSIWENCODEEXT]: Invalid argument


The ESSID is off/any:
Code: Select all
$ iwconfig wlan0
wlan0     IEEE 802.11abgn  ESSID:off/any 
          Mode:Managed  Frequency:2.412 GHz  Access Point: Not-Associated   
          Tx-Power=15 dBm   
          Retry short limit:7   RTS thr:off   Fragment thr:off
          Power Management:off
         
 


If I use
Code: Select all
-Dnl80211
, it appears to work:

Code: Select all
$ sudo wpa_supplicant -B -i wlan0 -Dnl80211 -c university_wpa
Successfully initialized wpa_supplicant


But the ESSID is still off:
Code: Select all
$ iwconfig wlan0
wlan0     IEEE 802.11abgn  ESSID:off/any 
          Mode:Managed  Frequency:2.412 GHz  Access Point: Not-Associated   
          Tx-Power=15 dBm   
          Retry short limit:7   RTS thr:off   Fragment thr:off
          Power Management:off
         


I run the same command with -d (verbose) to see what might be going on:
Code: Select all
 $ sudo wpa_supplicant -B -i wlan0 -Dnl80211 -c university_wpa -d

But I'm not sure how to interpret this.

Why is the ESSID not being set?

If I run iwconfig manually, I can set the ESSID:

Code: Select all
sudo iwconfig wlan0 essid MY-UNIVERSITY-SECURE
 $ iwconfig wlan0
wlan0     IEEE 802.11abgn  ESSID:"MY-UNIVERSITY-SECURE" 
          Mode:Managed  Frequency:2.412 GHz  Access Point: Not-Associated   
          Tx-Power=15 dBm   
          Retry short limit:7   RTS thr:off   Fragment thr:off
          Power Management:off
         
 $


contents of my-universitywpa:
Code: Select all
network={
   ssid="MY-UNIVERSITY-SECURE"
   scan_ssid=1
   key_mgmt=WPA-EAP
   pairwise=CCMP TKIP
   group=CCMP TKIP
   eap=PEAP
   identity="my-user"
   password="mypass"
   ca_cert="my-university_comodo_cert.pem"
   phase1="peapver=0"
   phase2="MSCHAPV2"
}


I've used these settings to connect on other machines without problems. But I've always used -Dwext, never -Dnl80211.

the driver is

.

I've searched online for this problem without luck. My university uses EAP authentication. Is this a problem between iwlwifi and -Dnl80211?

Re: wpa_supplicant fails to set essid

Postby erjoalgo » 2015-08-09 20:04

I ended up removing the -B (run daemon in background)

Code: Select all
sudo wpa_supplicant -i wlan0 -c wpaconfig -D nl80211,wext


and realize that my script wasn't waiting for the connection to complete:
Code: Select all
wlan0: CTRL-EVENT-CONNECTED - Connection to 00:11:22:33:44:55 completed [id=0 id_str=]


and was aborting early due to not seeing the essid. There seems to be no option to programmatically ask `wpa_supplicant` to daemonize itself only upon CTRL-EVENT-CONNECTED, so I might have to use a expect script for this.
