    Done. Thank you.

    OK, So I'm attempting to connect to a network via LEAP to no avail.

    auto lo
    iface lo inet loopback

    auto wlan0
    iface wlan0 inet dhcp
    wpa-driver wext
    wpa-ssid xxxxxxxx
    wpa-ap-scan 2
    wpa-eap LEAP
    wpa-key-mgmt IEEE8021X
    wpa-identity xxx.xxxxxxx
    wpa-password xxxxxxxx


    I have set the key encryption to "open"
    gksudo iwconfig wlan0 key open

    and I'm unable to connect. Any Ideas? Using 8.04

    Connecting With Broadcast Off

    I am unable to associate with a Belkin F5D8230 that is cloaked. I've tried the following in interfaces (wpa_supplicant.conf seems to be depreciated):

    Code:
    iface wlan0 inet static
    address 192.168.1.2
    netmask 255.255.255.0
    gateway 192.168.1.5
    #wireless-essid hex
    #wireless-key s:<key>
    wpa-ssid hex
    # 1=broadcast ESSID, 2=no broadcast
    wpa-ap-scan 2
    # WPA=WPA1, RSN=WPA2
    wpa-proto WPA
    # CCMP=AES cipher part of WPA2 standard, TKIP=TKIP cipher part of WPA1 standard.
    wpa-pairwise TKIP
    wpa-group TKIP
    # WPA-PSK=Authentication via pre-shared key, WPA-EAP=Enterprise authentication server.
    wpa-key-mgmt WPA-PSK
    # Generate key: wpa_passphrase <your_essid> <your_ascii_key>
    wpa-psk 85739200db1c87e1e4cb9a40bdbf427ca39955303b1af48da496237cc27c3eda
    It associates all day if Broadcast is on, but not with it off.

    The only comment dmesg or messages would have on the whole affair is:
    Code:
    ndiswrapper (link_pe_images:576): fixing KI_USER_SHARED_DATA address in the driver
    ndiswrapper: driver netw4x64 (Intel,03/13/2008,11.5.1.15) loaded

    Trying to get Edimax 7318UG to work but when I type 'dmesg' the following is shown on Hardy:

    Code:

    I see that a bug exists though here

    Edit:

    After changing Access point channel from 12 to a lower one and selecting wpa in the nm-applet window for entering a wpa2 encryption key it is now working!

    OK, I will be around for the weekend. Shoot if these problems have not been resolved yet.

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

    Wieman01: Thanks a million! Your instructions just work. For me, it's a first to have manual wireless setup work!

    I have a Sharp MP30, kind of old and slow by now, but I still love it. Atheros wireless chip. I run Hardy Heron. I used the "recipe" for WPA1, using dynamic IPs (dhcp), with a broadcast ssid.

    There were only two things I came across that might be confusing to someone who's even more of a newbie than I am:

    1) the wpa_passphrase command to get the hex equivalent is run in a terminal, at the usual command prompt. ie not as sudo. Also, if, like me you have spaces in your passphrase, put the whole thing in quotes.

    2) when making a link to the startup script, as described in the first comment, it says:
    sudo ln -s /etc/init.d/wireless-network.sh /etc/rcS.d/S40wireless-network
    [Note: You may have to choose a boot sequence other than S40.]
    To find the number that'll work for you, look at the /etc/rcS.d directory. I gave "wireless-network" a higher number than "networking" since I was guessing that the new script would be using the basic connectivity handled by "networking". "Networking" was S40 in my case, so I called it S41wireless-network. No other entry already had that number.

    Success! After a bit of mucking around trying different combinations of settings, both in my Ubuntu boc and in my router, and trying to make sense of the output after restarting the network, it works! Goodbye to WEP.


    Thanks!

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

    Can I just download wpa-supplicant somewhere?

    My Ubuntu install has NO connection due to this issue, and I really need to get it up and working (and it cannot use a hardwire connection right now).
