Re: BCM4312/b43 acts weird with NetworkManager and F13

Hi,

I'm running Fedora 13 with NetworkManager-0.8.1-1 and a 2.6.34 kernel from
koji. My system has a BCM4312 wifi chip which I'm using with the b43 module
and the proprietary firmware from Broadcom.


In Ubuntu, the native b43 module is broken, as the device is always disabled.

We have to block it and use the bcmwl-kernel-source, which installs a "wl" driver
that works.

Maybe this works for you, too?

NetworkManager is acting a bit weird with wifi. Every time I reboot the
laptop, the wireless connection is disabled, meaning I have to right click
on the nm-applet icon and choose "Enable wireless". Based on
/var/log/messages the firmware is loaded to the device at this point like
this:

NetworkManager[968]: <info> (wlan0): bringing up device.
kernel: b43-phy0: Loading firmware version 478.104 (2008-07-01 00:50:23)
kernel: ADDRCONF(NETDEV_UP): wlan0: link is not ready
dbus-daemon: [system] Rejected send message, 1 matched rules;
type="method_return", sender=":1.1" (uid=0 pid=968 comm="NetworkManager)
interface="(unset)" member="(unset)" error name="(unset)" requested_reply=0
destination=":1.56" (uid=500 pid=1563 comm="nm-applet))
NetworkManager[968]: <info> (wlan0): supplicant interface state:  starting
-> ready
NetworkManager[968]: <info> (wlan0): device state change: 2 -> 3 (reason
42)
NetworkManager[968]: <info> Activation (wlan0) starting connection 'Auto
<network name here>'

etc. etc.

With my previous laptop, which had an Intel wifi chip, the wireless network
was always automatically enabled when I booted up the computer. I know the
b43 drivers are still under development, but does anyone have an idea what
could be going wrong? The dbus error does look a bit scary to me.
