    Thanks for the help! BTW... I'm going to eventually do the WEP option but I want to see if the wireless card can work at ALL first.

    Re: How To: Manual Network Configuration without the need for Network Manager

    Something is wrong with your wireless driver -- seems like you may be a victim of the new b44/ssb/ndiswrapper conflict, although from what you posted things seem correct.

    Couple of things to check
    dmesg
    See jamie jackson's tutorial:

    Thanks, I'll keep digging.

    On a lark a remembered I had an old Linksys USB Network Adaptor and plugged that in. It shows up fine and even picks up a signal from my router and a couple of my neighbors' routers. BUT I can't connect to them. Could it be that my problem is in the wireless protocol itself and / or the Network Manager module? How would I check that?

    It could be a lot of things.

    Manual connection initially is the way to go if you are having problems. A lot of times debugging messages are presented that give you a clue what is not working. Once you getting it working and figure some things out, you can then migrate to NWM or WICD.

    Did everything in Jackson's how to. Still nothing.

    the lshw thing is coming up with everything that it is supposed to come with (except the part that says link=no which is like the thing is mocking me, but that's another story).

    Is anyone else having this problem?

    Check dmesg to see if you are getting any errors surround the install of the ndiswrapper/driver combo into the kernel.

    The list of errors is so large I wouldn't know where to look. AND I rebooted and it's back to square one. Nothing stuck. The wireless card doesn't show the "wlan0" interface in lshw and the module is back to being ssb.

    This is bordering on ridiculous.

    EDIT: This is what I see when I reboot and then run the sudo lshw -C network:

    Code:
     *-network

    Then I go through the "Try it out" part of Jamie's How To.

    Then I get this with lshw:

    Code:
      *-network

    This means it worked, right? But I still can't connect through the wireless card. And this time on reboot the friggin wifi light turned on just to taunt me.

    Re: How To: Manual Network Configuration without the need for Network Manager

    Did you do the following to make it permanent?:

    echo -e '#Hardy ssb/ndiswrapper workaround, added' `date` '\ninstall ndiswrapper modprobe -r b43 b44 b43legacy ssb; modprobe --ignore-install ndiswrapper $CMDLINE_OPTS; modprobe ssb; modprobe b44;' | sudo tee -a /etc/modprobe.d/ndiswrapper

    If you just cut and paste, it should bring you back to where you are currently at boot. You will never need to do this again since that script simply or addends things to the /etc/modprobe.d/ndiswrapper file. Take a look and the file to see if these things are not duplicated.

    Please look in dmesg for something if regards to ndiswrapper. That is what you are looking for. Forget everything else.

    Yeah, this second go around I made it permanent and the changes stuck. I still can't connect through wireless. WICD sees the wireless networks (mine and a few of my neighbors') but locks up when I try to connect to mine.

    I ran the dmesg and found references to ndiswrapper (I'm putting in everything from the first reference to the last):

    Code:
    [   47.261352] ndiswrapper version 1.52 loaded (smp=yes, preempt=no)

    Re: How To: Manual Network Configuration without the need for Network Manager

    Ok things look good.

    With the wired device down, and the wireless device up, please make sure you can see some other networks with
    (sudo ifconfig eth0 down, sudo ifconfig wlan0 up)

    iwlist scan

    Then try connecting if you can to a router or access point with no enabled encryption. Can you do this?
