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

    Hello, i have been looking around
    i have a dv2000 hp laptop with an AMD and the 64bit version of Gutsy
    My wireless network has WPA it works
    After i go thru a lot of hoops
    boot up, change the settings on my wireless ssid and password, click ok (they are already stored)
    change them back
    and the network manager does it thing and activates the connection

    i dont know why i dont get an IP at the moment of boot up, if i go to wired connection everything works as supposed
    i have a broadcom 43xx driver

    any ideas?... all i can think of is that unfortunatly my card is not trying to fetch an IP from the router

    i have tried static ip as well and it doesnt work

    pls help!

    You got to give me more details like how you are setting up your wpa connection. This post is really only concerned with setting up manual connections, and not with problems with network manager. I know a lot about network manager, but to delve into it here in this particular post would be a little off topic.

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

    Kevdog, I am hoping you are still around and can help me with this:

    My wifi card has the logical address of wifi0, but the iwlist scan is performed by ath0? Is this why I'm not getting any connection? And what about the wifi0: unknown hardware address type 801 error in the dhclient command?

    Please help me sever the cable!

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

    Your using the madwifi drivers. According to the madwifi specs it creates a virtual interface for each device. The device is wifi0, the virtual interface is ath0. All command line is directed toward the virtual interface, not the physical device itself. You need to probably specifiy a specific essid on the command line before the dhclient command. All though you mentioned the error with wifi0, where is the output that showed this error?

    where would I put the essid in the command? wifi0 error listed below.

    Look at the original post (first page). It will tell you where to put the essid. If that error persists, it could be a problem.

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

    I just ran trough the entire exercise again. Output below. I'm sure it has something to do with the unknown hardware 801 error after sudo dhclient -r ath1, but I don't know what to do about it. Is there a way I can start from scratch? maybe something wonky in a configuration file?

    Check your system logs (there is a reference in the reference section in the original post) to see if you find anything
