3) What happens
When turning on hardware switch for wifi, the network manager doesn't recognise the hardware (greyed entries for wifi).
4) What I expected
I expected it to recognise the wifi equipment and start scanning for wifi networks.
5) More info
Strangely enough, while reporting this bug (on a wired connection), the network manager started detecting wifi again.
I rebooted, and the bug came again.
I started reporting the bug, and the wired connection started again.
6) a few logs:

For me, the problem began without touching the hardware switch, I merely turned off wifi in network manager. To me, this issue seems related to https:/
Once on, I cannot turn "airplane mode" back off, and consequently I can't turn wifi on. Found a workaround here http://
sudo rfkill list all
shows that wifi is blocked
sudo rfkill unblock all
will unblock it. After that, wireless works again. Until you turn it off via network manager, or turn on "airplane mode", then the problem reappears.

Hi All,
I've had same issue with NM and Broadcom BCM4312 and b43 driver.
Usually I used 'iwlist wlan0 scanning' to make NM to wake up. But today I tried to play with configuration and it helped.
I've changed INACTIVE_TIMEOUT default value 1 to 10 in
/etc/conf.
(sorry I'm Gentoo user and not sure if it is in the same folder in Ubuntu)
Status changed to 'Confirmed' because the bug affects multiple users.
