    Default But it worked when I ran the live CD!...

    Hello all,

    I can't say that I am really new to Linux, but I will say that I am not very familiar. I have had some exposure to it over the years but one major hangup has kept me from fully embracing it: wireless! I have not often had the luxury of a wired internet connection.

    Recently I popped a live cd into my new laptop, prompted by my general dissatisfaction with Vista (and subconscious desire to rebel against something). To my surprise I was able to connect to my wireless network, no configuration required. I thought that surely this must mean that my wireless card was supported "out of the box" and I could finally kick windows to the curb. Unfortunately after install I am no longer able to connect! Wireless manager continually prompts for my WEP key or pass phrase. I have tried multiple distros and read through countless forums in search of an answer.

    I read through the sticky thread and here are the results of running the commands mentioned.

    dmesg output is very large, so here is just one bit that seems important. I can search for other info or post the whole file if needed.

    Please let me know if there is any other info that might help! Also, I am interested in knowing the technical details, if anyone feels compelled to share. At the moment I just need to get this laptop up and running ASAP!

    Also, I noticed these lines in dmesg output:

    Code:
    ADDRCONF(NETDEV_UP): wlan0: link is not ready
    and

    Code:
    ra0: no IPv6 routers present
    and

    Code:
    wlan0: authentication with AP 00:1d:7e:45:c2:04 timed out

    I tried disabling ipv6 and the above lines are no longer present in the output of dmesg (except for the AP timeout), but I am still unable to connect to my wireless network.

    I should note that wireless manager found my network and shows signal. Also, I have a built-in wireless card as well as a PCI Express card that I purchased recently (since the built-in card seemed to be problematic).
