Wireless Configuration Slackware 12.2 - wpa_supplicant error

Do7AN · 01-16-2009, 03:24 PM

I am receiving the following error.

Code:

/etc/rc.d/rc.inet1 wlan0_restart
/sbin/dhcpcd: not running
/etc/rc.d/rc.inet1:  wlan0 information: 'mywirelessnetwork'
Error for wireless request "Set Nickname" (8B1C) :
    SET failed on device wlan0 ; Operation not supported.
Failed to connect to wpa_supplicant - wpa_ctrl_open: No such file or directory
Failed to connect to wpa_supplicant - wpa_ctrl_open: No such file or directory

I am attempting to connect to my work's wireless network which uses radius authentication but is not using certificates or keys. I am fairly new to linux. My wireless card is an Intel 4965abgn in a HP 6910p. I have read AlienBob's wiki http://alien.slackbook.org/dokuwiki/...ckware:network and a portion of Slackware Essentials book (first 5 chapters). I have not yet been successful connect my wireless nic to any network.

1. Can anyone explain the error that I'm getting?
2. Is there away to verify that the wireless card is scanning for a network?
3. Is there anything wrong with my configuration?

Please let me know if there is any information I forgot to post.

I have sometime the same message "Failed to connect" but in the end the card connects to my wireless network.

I've remarked that your "iwconfig" command shows that the card is not associated with your network. To identify which Access Points are available, run as user 'root':

Code:

iwlist wlan0 scan

If you do not see your Access Point, try to move the card's antennae.

If you see your Access Point, it could be that your card needs more time to associate. As suggested in Alien Bob's wiki, try to increase the WPA timeout by adding this line in /etc/rc.d/rc.inet1.conf:

Code:

WLAN_WPAWAIT[4]=120  # 2 minutes

I ran the iwlist wlan0 scan and iwlist wlan0 power.... And this is what I got.

iwlist wlan0 scan

Code:

wlan0     No scan results

iwlist wlan0 power

Code:

wlan0     Current mode:off

I'm guessing that this means my wireless card is powered off? The button that turns on my wireless card is turned on and the light is on? Could I be missing something like correct firmware or driver?

gegechris99 - thank you for your help.

Hello,

Did you make a fresh install of 12.2 or did you upgrade from a previous version (which one)?

In the log of your command "dmesg | grep iwl", you can see:

Code:

firmware: requesting iwlwifi-4965-2.ucode
iwlagn: Radio disabled by HW RF Kill switch

Is the firmware package installed in your system? iwlwifi-4965-ucode-228

After some googling, the error may also be due to your BIOS setting. Try reloading your default BIOS settings.

Thank you gegechris99. You were an excellent help and my wireless is working perfectly now. Here is what I figured out. The wireless card was working fine. The problem was the radius authentication. I was not matching all requirements set by radius and I had a problem with my wpa_supplicant.conf. Below I have listed the correct configuration that I am using. this can be compared to the original that I add posted a the top. Again thank you gegechris99.

wpa_supplicant.conf

Code:

network={
        ssid="mywirelessnetwork"
        scan_ssid=1
        key_mgmt=WPA-EAP
        eap=PEAP
        pairwise=TKIP
        phase1="peaplabel=0"
        phase2="auth=MSCHAPV2"
        identity="username"
        password="password"
}
