    Looks fine actually. You have disabled SSID broadcast and use WPA-TKIP. What does a scan yield?
    sudo iwlist scan

    Re: HOWTO: Wireless Security - WPA1, WPA2, LEAP, etc.

    In my experience, the following instruction from the main thread

    <quote>
    VERY IMPORTANT:
    Now convert your WPA ASCII password using the following command (' ' single quotes required):

    wpa_passphrase 'ssid' 'ascii_key'
    </quote>

    did not actually require single quotes. wpa_passphrase generated a different key when single quotes were used which was rejected by my router. removing the single quotes and generating the key again solved this for me.

    i am using a netgear wgr614v5 wireless router with a netgear wg511 (version 1 made in taiwan) pcmcia card on an acer laptop.

    Thanks for highlighting that. I have corrected the tutorial accordingly.

    My router is "Cell 02" in that list. I also use MAC filters, would that make an effect?

    I also managed to enable the front LED and when I used my earlier /etc/network/interfaces and rebooted, Ubuntu slowed at 3/4 of the way and resulted in the GNOME.DESKTOP error I mention, but the LED was solid i.e. connected

    Re: HOWTO: Wireless Security - WPA1, WPA2, LEAP, etc.

    @Gladstone:

    Everything looks fine to me. But beats me, I don't know what's going on. MAC filtering could be an issue but only if the registered MAC isn't the same as the one listed above (00:03:2F:2B:71:6B).

    Have you turned roaming off?

    I have a problem. I installed ubuntu in my machine and there's one problem. Wireless problem. The OS detect all the hardware perfectly and everything runs fine except for the wireless. The OS can detect wireless networks but could not connect to it. I attach together the screenshot and hopefully anyone can try to give me solution for this. Oh yes, the wireless was Realtek RTL8187. Thanks.

    Please open a new separate thread for your this issue. It has not really anything do to with this one. But feel free to send me the link by PM.

    Initially having no idea what had happened (I couldn't login), I managed to pin-point it back to the /etc/network/interfaces file I just edited.

    The bug has been discussed here:

    https://bugs.launchpad.net/ubuntu/+s...ter/+bug/61381

    and more specifically:

    https://bugs.launchpad.net/ubuntu/+s...81/comments/43

    https://bugs.launchpad.net/ubuntu/+s...81/comments/23

    However, during that time, my wireless was working!

    Is there anything I can try? I can remember another guide adding something like DISABLED=1 to /etc/wpa_supplicant.conf (I saw it mentioned in the Launchpad thread)... Is that the correct command?
    what does your /etc/network/interfaces look like..? what wireless card and driver are you using? A quick glance at your earlier post show you have a
    dns-nameserver
    in your interfaces file?

    Horrrayy!

    Thanks houms, it was that rogue dns-nameservers that was causing all the problems. I'm not sure where I picked that up from, but I've been adding bits of things from all over the place over the last 2 weeks to get this working I hope it's not just all part of the learning curve!

    I also have to use the network restart script for it to work (as described in post 2 here)
