    For your unencrypted network, can you post
    iwlist scan

    Try to connect from the command line leaving out the mode Managed part.
    took awhile, But I have it. XP works with not encryption so I have to keep booting back to post. I have tried 'unsetting' everything to get back to Unencrypted operation in Kubuntu, but it's not happy. Here's the gen:

    Thanks for any help. I'll keep playing to try and get it working 'open'. Would it help to uninstall wpa_supplicant, even though it is not configured?

    Im not sure what to make about this line:

    Try connecting from the command line for eth1. The instructions are in my signature. Try just a regular unencrypted connection first.

    Kevdog - you helped me out a while back on a wireless connection problem. I was hoping you could do teh same again. I am now setting up a Dell Latitude 600 with Ubuntu 7.10. Hard drive was empty do it's a fresh install. i have a listing of the following:
    lshw -C network
    route
    ifconfig
    iwlist scan.

    What commands have you typed at the command line to attempt to connect?

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

    I have an update: I was able to use a static ip address and now able to get online. But I would still like to have dhcp working and not have to use a static ip. Any suggestions?
    I am using wicd as my network manager.
    DHCP would allow me to have this laptop to move on to other networks.

    any help. thanks in advance.

    Once I uninstalled wpa_supplicant, the unencrypted connection worked. This is coming over an unencrypted wireless link.

    Note I have restricted speed to 802.11b as it gives better range through walls than g, and with a 512Kb/s broadband I don't need faster Wireless. Also Channel 11 to be aways from others in neighborhood.

    Almost tempted to re-install wpa_supplicant and the kwlan gui manager for it, and see if that works. I didn't use kwlan last time.

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

    I think Madsmaddad found a way to do this already, but for anyone getting the "No DHCP Offers" message try:

    sudo iwconfig [interface] key open

    I found that when looking up the parameters of iwconfig on google.. it led me to: http://gd4.tuwien.ac.at/.vhost/linux...iwconfig8.html


    This is only my second day as a linx user (running Xubunto wirelessly atm), so I dont know if that helps any.. but I'm thinking the reason so many people are getting that error message is because their WEP settings on their router dont have "shared keys" but "open keys," if that makes any sense.. hope this helps.

    Oh, and thanks a lot for the tutorial Kevdog... i've been going through a lot of troubles installing Xubuntu (install cd not burning, updates not working, loose video card making my system freeze, etc.) but its nice to finally have a working wireless system to play around with!

    Updated the thread instructions with your suggestion. I dont really use WEP a whole bunch. The iwconfig documentation gives a poor explanation of when to use or not use the open command. Hopefully people will try this command if they are receiving problems when trying to make a WEP connection
