    Re: HowTo: WPA with wpa_supplicant

    Luca... thank you so much!! I made my wireless work (Intel 2915abg work on XPS m170 laptop) doing everything outlined in your how-to. The last few suggestions did the trick for me after a quick reboot. Again thank you!!!! I have looked at a ton of other forum entries and yours did the trick!

    Ciao,
    Alex

    Re: HowTo: WPA with wpa_supplicant

    hi, i´m using a laptop with a broadcom wireless card, 4318, after trying first with ndiswrapper and was working fine, now i use bcm43xx-fwcutter and works +-, worst than ndiswrapper, but i was unable to activate wpa with ndiswrappper.

    well, on Kubuntu, every time i boot my laptop i have to make 2 things to have wireless working and connected to my wpa protected home lan.

    first: run kwlan, and wait for a message that says: "eth1 is connected"
    second: after that message, run in terminal "sudo dhclient eth1".

    i have to make those steps every boot.

    there is any way to get always eth1 connected?, and get ip from dhcp automatically?

    thx

    Question Re: HowTo: WPA with wpa_supplicant

    Question:

    How do I set this up on a laptop (HP NC6220) with IPW2200 (Intel 2915ABG), but I have to use a certificate file vs PSK?

    Re: HowTo: WPA with wpa_supplicant

    I read somewhere that ctrl_interface does not work well with wpa_supplicant and you can probably sidestep the problem by removing the lines at the beginning of the config that start with ctrl_interface.

    Hope that helps.

    Re: HowTo: WPA with wpa_supplicant

    Sorry, I just recently switched to Ubuntu. I think I can connect to my network, or at least wpa_supplicant tells me I can but I'm still unable to access the internet for some odd reason. Any tips?

    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?
    I have the same problem. Mine is a PCMCIA SMC card, and i'm using ndiswrapper.
    Any idea what is causing the disconnections?

    Re: HowTo: WPA with wpa_supplicant

    I have exactly the same problem. I'm using IBM R50e laptop, Kubuntu 6.10, ipw2200 with latest drivers (1.2.1) and firmware (3.0).

    I'm connecting to Linksys WRT54GS, firmware 1.5.2.

    I tried manually configuring wpa_supplicant and KNetworkManager. Same problem.

    My Ralink card (desktop) connects just fine to my router using WPA, and my laptop connects without a problem to an open AP.

    It seems the card associates and then tries to associate again, gets an error and disconnects.

    Re: HowTo: WPA with wpa_supplicant

    I was having the same problem with an ipw card. Network Manager now comes with 6.1, and I finally fixed the problem by going to /etc/network/interfaces file and commenting out everything except for lo - then ran network manager and it worked like a champ!

    Re: HowTo: WPA with wpa_supplicant

    This guide gets me up and running for a short time in Edgy, then nothing after any period of inactivity. My network manager applet shows a "wired network RaLink RT2561/RT61 802.11g pc", or did before I implemented the things in the first post of this thread. The card is actually a Linksys PCI card, WMP54g. I drop after a few minutes of inactivity and can't figure out why or how to restore connection without restarting the machine.

    Re: HowTo: WPA with wpa_supplicant

    I tried the instructions and no joy at all with wpa_supplicant

    I have a lot of questions about these instructions. I will go step by step

    1. Ran the following in terminal window:
    Code:
    wpa_passphrase 'MYSSID' 'MY_PSK'
    Where 'MYSSID' and 'MY_PSK' correspond with that of my wireless router.

    I got the resultant psk string and copied it

    2. Ran
    Code:
    sudo gedit /etc/wpa_supplicant.conf
    A blank file opened. Is that normal? I followed the instructions adding the following to the .conf file:

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

    network={
    ssid='MYSSID'
    scan_ssid=1
    proto=WPA RSN
    key_mgmt=WPA-PSK
    pairwise=CCMP TKIP
    group=CCMP TKIP
    psk='MY_PSK_STRING'
    }
    I saved this file.

    3. I ran
    Code:
    sudo gedit /etc/network/interfaces
    Here is where things got kind of confusing. What you see below is what I currently have in that file. I placed what the instructions said under 'auto eth0' originally but that immediately dropped my wired connection when I ran wpa_supplicant in the final step. So I fixed it by placing the info from the instructions under auto eth1 since that is my wireless card when I run iwconfig. I am also using ndiswrapper to install my Windows driver so I changed that too.:

    auto lo
    iface lo inet loopback

    auto eth0
    iface eth0 inet dhcp

    auto eth1
    iface eth1 inet dhcp
    wireless-essid "XBOXWAP"
    pre-up wpa_supplicant -Bw -Dndiswrapper -ieth1 -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
    iface wlan0 inet dhcp
    4. when I run
    Code:
    sudo wpa_supplicant -Bw -Dndiswrapper -i eth1 -c/etc/wpa_supplicant.conf
    ... nothing happens. Here are the results when I run it with the -dd switch

    You may have another wpa_supplicant process already running or the file was
    left by an unclean termination of wpa_supplicant in which case you will need
    to manually remove this file before starting wpa_supplicant again.

    Anyone? I'm a total noob, so I may need some rudimentary instruction.

    As another note, I have wifi radar running and it is at least seeing my neighbor's networks so I think the driver is working on some level.

    Also, my SSID is hidden, if that is complicating things (??)

    And the driver does support WPA. At least in Windows it does.
