wmaster0 ate my hamster, i mean wifi

[fisheep]

Hi all, I wonder if any of you kind folks will know what's gone wrong here. Since upgrading to Kubuntu Hardy Heron (via the upgrader from the previous release), I've found myself hungering for the wifi freedom that Gutsy provided so unquestioningly. That is to say, it has stopped working since the upgrade. KNetworkManager stops on "Activation stage: Configuring device." It sits like that for a while before throwing up its hands and asking me to enter my network settings- KNetworkManager's little way of saying "well that didn't work."

I decided to look on these hallowed forums for help. And I did (ooh). And there was (hooray!). But it didn't (drat). I refer to this:

So I started from the beginning and lshw -C reported this:

"Wmaster0? This is new," I thought to myself. "The wireless network card always used to appear as eth1. And interestingly it used to work. Okay, it's called wmaster0 now." So I followed the instructions (for WEP), and got as far as this:

Not good, I like being able to connect to my AP. I know, I'll try with good old eth1. This was beguilingly encouraging, I got as far as

alex@pineapple:~$ sudo ifconfig eth1 down
alex@pineapple:~$ sudo dhclient -r eth1

Have any of you got any clues as to what I'm doing wrong? I'm hoping it'll be as simple as "force a reinstall of package X" :) Please let me know if I can post any handy logfiles or whatnot.

My machine is a Lenovo ThinkPad x60t, if that's relevant. And it was perfectly happy in Gutsy.

Thanks for any help!

Hello,
I have exactly the same issues and I do not see my wireless card under System/Administration/Hardware devices.
:confused:

[andreselsuave]

Hi, I have the same problem, the GUI network manager sometimes works but sometimes don't... so I want to install network via command line and i also have the wmaster0 name... and i get the same errors as you. By the way, i'm using ubuntu Hardy Heron in a HP Compaq 8710p laptop.

Thanks for your help in advance!

FYI, the wmaster0 interface is created by the new mac80211 driver.

More information about this is available at http://linuxwireless.org/en/developers/Documentation/mac80211. I suggest viewing that website for more information about the state of wireless development in the linux kernel.

Let me just say this. I have a perfectly working 3945ABG that I am replying on right now. I have a wmaster0. Ignore it. It does nothing to help or hurt you. Only you can decide to worry about it, or not. So don't.

You have a variety of issues.

@andreselsuave- Why is your interface DISABLED? Please do:sudo cat /var/log/messages | grep KillDoes it report the kill switch is on? Flip that switch or key combination and let's get wireless going.

@fisheep- Network Manager, which is installed by default, will not activate wireless as long as you have a working connection by wire, which you do:ip=192.168.0.5Until you detach the wire and restart networking:sudo /etc/init.d/networking restartthen NM will try to help you get your wireless connected. You should be able to run:iwconfigand see that your wireless interface is really either wlan0 or eth1.
