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

    i too am also trying to get the wireless working on my ubuntu server.

    i followed you beginning tutorial and i am still not connecting.

    iwconfig shows the ESSID

    however, when i enter in

    /etc/init.d/networking restart

    i get the following message

    wpa_supplicant: /sbin/wpa_supplicant daemon failed to start
    run-parts: /etc/network/if-pre-up.d/wpasupplicant exited with return code 1
    I know the wireless works because I was using it when I had the machine running the Ubuntu Desktop.

    I am also using WPA and TKIP with the static addressing.

    any ideas why?
    I got Questions. I hope you have answers!

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

    Hello Guys.

    I'm trying to configure my wireless connection on my server but something weird is happening.
    I have two cards on my server, one wired and another one wireless.
    After set up all the setting of wpa_supplicant and execute the commands to connect, the wlan0 network get IP and connected on my AP.
    But, when I log into my AP and ask to list all attached devices, I see the wlan0 card connected with the same MAC Address from the wired card. And if I unplug the network cabe from eth0, both connections goes down.

    I will sent the steps that I followed with my configuration files to see if you can help me, please.

    # The primary network interface
    auto eth0
    iface eth0 inet dhcp

    #wireless
    auto wlan0
    iface wlan0 inet dhcp


    Follow the output of the attached devices from router:

    4 192.168.1.10 SERVER 00:08:54:21:27:1F

    if you can see, the MAC is the same of the eth0.

    What is wrong? I want to use only the wireless card..is it possible, right?

    I'm running ubutu 12.04.

    Thanks in advanced by any help.

    Question HIDDEN SSID, what can I do?

    Hi!

    I have only CLI access to a machine, I want to config to connect to a Hidden SSID AP, but it can't. It works with SSID boardcast.

    The config (/etc/network/interfaces):

    Code:
    auto wlan0
    iface wlan0 inet dhcp
    	wpa-ssid <name>
    	wpa-psk <hex>
    It works with SSID boardcast. If I hide SSID, and add this line, it don't want to work.
    Code:
    wpa-ap-scan 2
    What else must I add to work?

    Thank you!

    UPDATE: I've found a solution here.

    Re: HIDDEN SSID, what can I do?

    I know this might not be a satisfying answer, but hiding the SSID adds no extra security. You might want to broadcast it and take the path of least resistance.

    Thank you so much. I spent all day trying to get the wireless working on my acer aspire one (the mini kind) with ubuntu 12.04.1 web server. With this guide I was able to do it. Very helpful. Like the Chinese character too.

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

    Raring Ringtail on every boot (with U+1 I do a lot of boots) does not automatically connect to WPA wireless.

    Raring invariably lways "disconnects" on boot. Systems Settings Network says "out of range" obviously tried to connect without the encryption key it already has. Manually select drop down window, shows the correct network, select it, and after a while presents a drop down with all the required info, and waits for me to select it. I do, and after a while it connects. Syslog has some network manager messages about "secrets required" and is oblivious to the "secrets" network manager already has.

    Pangolin on the same pc and netowrk connects autmatically, might take a couple seconds. Raring doesn't connect, as a matter of Network Manager policy.

    Android tablets on the same network (7" and 10.1") set up encryption once and they connect immediately. Every time. Raring doesn't.

    Chromebook boots, zooms up, connects, and bam into the internet. Once encryption is set up always boots right up, using the info, no manual intervention required.

    Launchpad bug#1097002. Apparently not considered a bug, just the way Ubuntu Raring network manager has decided to slow down boot.
