    A slight oversight. Nothing more. It certainly does not mean I am on the wrong path. He still, needs to follow those articles, and still needs to set up NetworkManager as directed. I find it easier to start from the begining, and ensure everything is covered.

    Thanks very much for the suggestions.

    - I have triple checked the wireless key; it is definitely being entered correctly.

    - I am unable to remove encryption on the router - it is a French device (Freebox v5 - WiKi Free) that is controlled via their website. I have to choose either WEP or WPA.

    - For WPA I have three options: WPA (TKIP + AES), WPA (TKIP) or WPA (AES/CCMP). The default is the first one, which I think is the same as WPA1/WPA2. I have tried the two other options with no success.

    - I have tried channel 6 and channel 11: no success. Each time I noticed that some of the other nearby AP's also change to the same channel - is this normal?

    - One other thing: if I run the NWData script while NetworkManager is trying to connect, I get a different error code that refers to the DHCP server. See results below:

    During connection: nopaste.info - free nopaste script and service
    After failed connection: nopaste.info - free nopaste script and service

    My current setup is using channel 6 and WPA1(TKIP).

    Although you get a DHCP error, the problem is not DHCP itself.

    Association to the AP is not working, so "no IP via DHCP" is a symptom but not the "illness".

    You have a (nowadays) rare device and I don't find any obvious error(s) in your setup.

    Maybe it is a driver issue, so I suggest to try a newer driver.

    Software.openSUSE.org

    Search for "compat-wireless" and read this here first:

    Based on the second link, my system info is as follows:

    Kernel version : 2.6.27.37-0.1
    Kernel flavor : pae
    openSUSE version : 11.1
    Architecture : i586

    I have found a handful of compat-wireless packages that seem to be appropriate. However, I'm not exactly sure what I am meant to do next. I tried installing one of the packages:
    Code:
    compat-wireless-kmp-pae-2.6.20091009_2.6.27.37_0.1-2.4.i586.rpm
    Is there another step? I rebooted the computer, and while I can still see the available APs, the blue wireless light is off and the radio button on the laptop has no effect. The NWData script returns these errors:
    Code:
    !!! CND0120E: Network card wlan0 has no IP address
    !!! CND0380E: No WLANs detected on interface wlan0. Hardware and/or driver not configured properly
    !!! CND0320E: WLAN turned off by hardware or software switch
    I just wanted to check if I was making a basic error, or if I should try some of the other similar compat-wireless packages.

    Looks like bleeding edge stuff (from 2.6.32rc with a completely rewritten rfkill-framework).

    Try another package with 2.6.30.X based modules instead.

    Okay, the blue light is back on. I installed:
    Code:
    compat-wireless-kmp-pae-2.6.30.9_2.6.27.37_0.1-8.3.i586.rpm
    I'm now back to the same error codes as before, although there do seem to be a few differences in the main part of the script results:

    nopaste.info - free nopaste script and service

    Again, Association to the AP fails, the outputs of iwlist wlan0 scan look different, but this is due to new capabilities of the drivers.

    To exclude _any_ (hopefully) issues related to NetworkManager and work on the "bare metal", do this.

    - Create a file /tmp/wpa_supplicant.conf.

    Code:
    ctrl_interface=DIR=/var/run/wpa_supplicant
    ap_scan=1
    update_config=1
    
    network={
            ssid="YOUR_ESSID"
            psk="YOUR_PASSPHRASE"
            key_mgmt=WPA-PSK
    }
    - Get a shell, become root with su and run

    Code:
    rcnetwork stop #stop all networking scripts/tools
    
    killall wpa_supplicant # just to be sure
    
    ifconfig wlan0 up 
    
    wpa_supplicant -Dwext -iwlan0 -dd -B -c /tmp/wpa_supplicant.conf
    
    iwconfig wlan0
    If you are associated with the AP as seen by iwconfig, then run "dhcpd" as last command, you should be online then.

    Post full outputs.

    I have followed the instructions but did not become associated with the AP; see results here:

    nopaste.info - free nopaste script and service

    I tried running the final command anyway, which wasn't recognised. Was it meant to be "dhcpcd" instead of "dhcpd"?

    Yes, I meant dhcpcd.

    Wait for one of the driver gurus, I see no obvioius user/configuration errors.

    You can also try to find a newer version of wpa_supplicant in OBS (use search site posted before) and repeat the procedure.

    If the wpa_supplicant has been compiled with "nl80211"-extension*, you can use "-Dnl80211" instead of "-Dwext".

    *
    Code:
     wpa_supplicant |grep -A10 drivers
    drivers:
      otus = Otus 802.11 WPA support interface
      wext = Linux wireless extensions (generic)
      nl80211 = Linux nl80211/cfg80211
      hostap = Host AP driver (Intersil Prism2/2.5/3)
      prism54 = Prism54.org driver (Intersil Prism GT/Duette/Indigo)
      madwifi = MADWIFI 802.11 support (Atheros, etc.)
      atmel = ATMEL AT76C5XXx (USB, PCMCIA)
      broadcom = Broadcom wl.o driver
      wired = Wired Ethernet driver
      ralink = Ralink Wireless Client driver
    --
      -D = driver name (can be multiple drivers: nl80211,wext)
      -f = log output to debug file instead of stdout
      -g = global ctrl_interface
      -K = include keys (passwords, etc.) in debug output
      -t = include timestamp in debug messages
      -h = show this help text
      -L = show license (GPL and BSD)
      -p = driver parameters
      -P = PID file
      -q = decrease debugging verbosity (-qq even less)
      -u = enable DBus control interface

    Okay, thanks for your help.

    I tried a different version of WPA_supplicant (0.6.9-7.1) to replace the original version (0.6.4-15.13.1).

    That didn't work either, so I'll wait for the driver gurus. I guess it might be easier to just buy a new wireless card...

    I should probably change the thread title as well!
