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


    Not to bring an old thread back to life, but just wanted to say thanks to wieman01 & the many others in this thread. After much hair pulling, I'm up and running in Ubuntu 13.04 using WPA2!

    One question though - I've only updated the /etc/network/interfaces file, and when I boot up, wireless is automatically connected (not complaining ). Throughout the thread I've seen mentions to a configuration in order to have the wireless connect at boot. Is there something that has changed over the releases to make this automatically happen, or have I done something unknowingly to make this happen?

    Should anyone be interested, I've included my configurations below. Note: I uninstalled network manager after struggling for many days. I found that I wasn't finding my network name in the iwlist scan results. Once I removed network manager, my network name popped up. No idea if it is relevant, but just thought I'd throw it out there. I also tried running the 'wpa_supplicant -Dwext -iwlan0 -c/etc/wpa_supplicant.conf -dd' command with no success. Would be interested if anyone could fill me in on why this command doesn't work, but simply configuring the /etc/network/interfaces file does.

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

    Thank you for the feedback, AvocadoRed! I am thrilled to see this still works after so many years.

    Perhaps something has changed over the years in terms of wireless connection at boot, I am not entirely sure. But I noticed this as well, I no longer need the scripts mentioned in post 2.

    And thanks for posting the contents of your configuration files for reference!
