    Re: HowTo: WPA with wpa_supplicant

    I followed this set of instructions and it all went smoothly, bar forgetting to change eth0 to eth2 in my case. I'm using a Broadcomm chipset card, Belkin F5D7001UK, if that helps anyone who's unsure whether it will work or not.

    Re: HowTo: WPA with wpa_supplicant

    Hi,

    I'm new with Linux...I'm trying to use my WPA-wifi connection with my notebook... the wifi card is a Intel 2200BG.

    This is what I've done so far:

    sudo kwrite /etc/wpa_supplicant.conf

    ctrl_interface=/var/run/wpa_supplicant
    #ap_scan=2

    network={
    ssid=Sydney
    scan_ssid=1
    proto=WPA RSN
    key_mgmt=WPA-PSK
    pairwise=CCMP TKIP
    group=CCMP TKIP
    psk=370d97a2c2d4564c0c34647ac4d57f9b49b068f06aae32 b2df243d48a74408771
    }

    (SSID and PSK aren't the one I use, just copy and pasted and changed a bit)

    Then....

    sudo kwrite /etc/network/interfaces

    auto lo
    iface lo inet loopback

    auto eth0
    iface eth0 inet dhcp

    auto eth1
    iface eth1 inet dhcp
    iface wlan0 inet dhcp
    wireless-essid Sydney
    pre-up wpa_supplicant -Bw -Dwext -ieth0 -c/etc/wpa_supplicant.conf
    post-down killall -q wpa_supplicant

    auto eth2
    iface eth2 inet dhcp

    auto ath0
    iface ath0 inet dhcp

    auto wlan0

    and last

    sudo wpa_supplicant -Bw -Dwext -i eth0 -c/etc/wpa_supplicant.conf

    ....everything should work but it doesn't...

    So...anyone can help me?

    I'm not sure if this makes any difference but I receive this message when I'm running Kwrite...

    Re: HowTo: WPA with wpa_supplicant

    First off, thanks Luca. I used your previous how-to for an install about a year ago, and this one has me close to wireless. My last problem is that for some reason it keeps dropping and picking up the access point
    Code:
    iablt:/home/iab# iwevent

    You can see the Bit rate, signal level, noise level and the associated channel 0 then have values.

    My wpa_supplicant.conf and interface files are cut and paste from your how-to, excepting for my ssid and psk. The machine has a Intel Corporation PRO/Wireless 2200BG Network Connection (rev 05)
    I don't think this *should* make any difference, but I am running debian etch with kernel 2.6.17 Any ideas?

    You're amazing! uch a star! I followed your tutorial and it worked on the first time. After following step by step I just rebooted and off it went.

    Re: HowTo: WPA with wpa_supplicant

    i'm wondering if router affect this

    I have two linksys routers, one a WRT54G and a WRT54GL
    both with DD-WRT v23 SP2, both with the same SSID and PSK.

    The 54GL likes wpa_supplicant, then WRT54G gives me this error:
    CTRL-EVENT-DISCONNECTED - Disconnect event - remove keys


    any thoughts?

    Can you tell me where is this debug or how command you use ? I need this information - I have a problem concerning WPA-TKIP.
    Many thanks !

    L.S.,

    After trying a number of different options I managed to get connection working. I will detail the options on a website in Dutch so other people who want to use wpa on a Dutch network can find help. Thanks for all the advise here on these pages.

    Angry ipw2200, unable to find/scan network

    I had wireless working with Ubuntu until I upgraded to Edgy (I did a clean wipe and install), but I am totally stumped at why I can't get it to work anymore. I've followed every post in this thread and tried playing around with many different configuration settings, but I've had absolutely no luck.

    My main problem is that my wireless card can't find (scan?) my network (I have an Intel ipw2200 wireless card, and the device is eth1), nor any networks for that matter. My network's name is "dude wireless" and uses WEP encryption. My Debian desktop is connected to it just fine. I've tried both the wext and ipw drivers for wpa_supplicant, but neither of them worked.

    Here is the output of a ton of commands/files, so if anyone can help me figure out what's wrong, I would appreciate it.

    Re: HowTo: WPA with wpa_supplicant

    I don't have a clue why, but now suddenly it works. Its so weird, I didn't change anything from my post above! Oh well, I'm just happy to have it working finally.

    Post Re: HowTo: WPA with wpa_supplicant

    First of all, I'm new to this so go easy on me. I have come to the part where I'm to paste that thread in to interfaces. But I'm not sure where, under the eth0 or wlan0?

    this is what interfaces says:

    auto lo
    iface lo inet loopback

    auto eth0
    iface eth0 inet dhcp

    auto eth2
    iface eth2 inet dhcp

    auto ath0
    iface ath0 inet dhcp

    auto wlan0 inet dhcp
    iface wlan0 inet dhcp

    auto eth1
    iface eth1 inet dhcp


    And should I get any reply when I try to run Wpa_supplicant? I don't get any =S

    Thanks in advance
