    Wink Re: How To: Troubleshoot your Wireless Network Connection - Connecting at Command Li

    Well I, # out what ndiswrapper configured in /etc/modules, and /etc/modprobe.d/blacklist. I set /etc/network/interfaces to

    auto lo
    iface lo inet loopback

    I have Wireless back, I have been using the internet for the past 3 hrs, on another router, not mine. I disabled my WEP about an hour ago, and the NM still showes a security key in the NM Wireless networks. I will watch and see what happens!!!!!

    I can't believe I missed this but...

    sudo ifconfig ath0 up
    sudo dhclient ath0 essid myessid
    <ignore error messages>
    <open webbrowser and...>

    Internet all works! I think my problem before was that when I saw errors in the command line and NM still showed unconnected, I nievely thought that it mustn't have worked, yet when I actually use a browser / instant messenger / adept it all just works. Almost instantly NM then notices and shows connected.

    Happy d'oh!

    It does. Kubuntu Feisty and Gutsy both connected fine to my router. I am using a 3COM 3CRUSB100075 usb stick.

    This is without encryption. I am still trying to get WPA working.

    Thanks for the tip about connecting to a hidden SSID.

    How are you trying to get WPA working?

    Re: How To: Troubleshoot your Wireless Network Connection - Connecting at Command Li

    Tried via the Gui programs: is it kwifimanager? But it didn't work, then tried installing wpa_supplicant, and it didn't work either, But thanks to your post about the wkihelps, I have learned that supplicant does not support ZD1211 chipset, so am thinking that I am back to square 1.

    Still have encryption enabled on my router, so am doing this from XP, which means I can't get at all the info about what I have done.

    Any pointers appreciated.

    http://hostap.epitest.fi/wpa_supplicant/

    does not show the Zydas ZD1211 chipset as being supported.

    I note that page was last updated 2/12/07, so guess that the information is current.

    Re: How To: Troubleshoot your Wireless Network Connection - Connecting at Command Li

    I started another thread but this thread already seems to be dealing with my issues. My problem is that I can connect to secured networks (at least 2 different networks) but I cannot connect to any unsecured networks. To connect to my secured network I am using:
    Code:
    sudo ifconfig eth1 down
    sudo iwconfig eth1 essid 'MY_NETWORKS_ESSID' key MY_KEY mode Managed
    sudo ifconfig eth1 up
    sudo dhclient eth1
    It works and I have a connection.
    When I try to connect to an unsecured network with:
    Code:
    sudo ifconfig eth1 down
    sudo iwconfig eth1 mode Managed essid 'NETGEAR'
    sudo ifconfig eth1 up
    sudo dhclient eth1
    I get the error:
    Code:
    There is already a pid file /var/run/dhclient.pid with pid 7188

    For your zydas card, what driver are you using??


    ----


    For your unencrypted network, can you post
    iwlist scan

    Try to connect from the command line leaving out the mode Managed part.
