Wireless is disabled on boot

Bug Description

Ubuntu Maverick

When I boot and then log in, wireless does not connect. If I then use nm-applet, I see that wireless is disabled and also impossible to enable (greyed out).

The only way I have found to fix this is to open up jockey-gtk, remove Broadcom STA and then activate Broadcom STA. This is forgotten after every single boot, so I have to go through this 3 - 5 minute process every time I boot if I want to access my wireless network.

I've tried rmmod-ing and then modprobe-ing wl as an alternative, but that doesn't seem to do anything useful.

This is a regression compared to Lucid and Karmic. Wireless was flawless before I upgraded from Lucid to Maverick.

The same bug affects me (regression on upgrade from lucid to maverick), with the same driver (bcmwl-kernel-source).

I note for the reporter (assuming the problem is actually identical) that right-clicking on the wireless taskbar logo and ticking "Enable Wireless" successfully brings the device back up, and a short while afterwards a wireless connection is successfully made (and stays up).

On boot, lshw reports the same, except this entry starts " *-network DISABLED".
On boot, lsmod reports that wl is already loaded as above.

I'm not sure whether this is a bug with the driver (bcmwl-kernel-source) or networkmanager (network-manager-gnome).

Looking at the state of some things in the /sys hierarchy before and after checking "enable wireless" in network manager. I'm not sure if these are helpful or irrelevant, but it probably doesn't hurt...

/sys/bus/pci/devices/0000:07:00.0/enable "1" (before and after)
/sys/bus/pci/devices/0000:07:00.0/power/control "on" (before and after)

/sys/bus/pci/devices/0000:07:00.0/net/eth2/carrier "invalid node" -> "0"
/sys/bus/pci/devices/0000:07:00.0/net/eth2/dormant "invalid node" -> "0"
/sys/bus/pci/devices/0000:07:00.0/net/eth2/flags "0x1002" -> "0x1003"
/sys/bus/pci/devices/0000:07:00.0/net/eth2/link_mode "0" -> "1"
/sys/bus/pci/devices/0000:07:00.0/net/eth2/operstate "down" -> "up"
/sys/bus/pci/devices/0000:07:00.0/net/eth2/power/control "auto" (before and after)

In the end, I went back to the b43 driver. That _also_ has a bug in
it. Even after I have worked around that, I still have to right click
and enable wireless when I start each new session. Standby and
hibernation break the wireless (seemingly irreparably) and I have to

The difference between your bug and my bug (or perhaps the way they
manifest themselves, they may still be the same) is that I couldn't
enable wireless, because it was greyed out.

blacklisting the acer_wmi module fixed both the startup and suspend/hibernate issues for me (b43 on Lenovo S10) as per http://lkml.org/lkml/2010/3/22/472


I have this problem on Dell Inspiron 1545.

'Enable Wireless' in network manager is grayed out on boot.
I toggle the hardware button to disable wireless and run "sudo rfkill unblock all". Now the manager shows that wireless is disabled.
I toggle the button again and run the command again. Now the wireless is enabled again.
Using this command without toggling the button doesn't work.

This used to be an occasional problem that would be fixed by rebooting. It stayed when I started using the above method, until now. Now it just disappeared. "sudo rfkill list all" doesn't show anything now.
