[Natty] [Kubuntu] Cannot enable wireless in Network Manager plasmoid

[Scott Testerman]

Binary package hint: plasma-widget-networkmanagement

Clicking the "enable wireless" button in the Network Management plasma applet does not enable wireless. The "+ Show More" button is missing from the applet, and is briefly visible when trying to check the box to enable wireless. The button immediately disappears and wireless is not enabled.

The proprietary wl module is loaded and in use, according to Proprietary Drivers.

This appears to be the same behavior reported in bug 689529 and bug 745394. My state file shows that it thinks wireless is enabled, but I can verify both from the LED status and from iwconfig that wireless networking is not enabled.

ubuntu 11.04 beta1 wireless detected drivers loaded, but cant enable (enable wireless thick mark changes nothing) same for usb connected wireless card.

The same problem that had henrisk.
I tried the internal ath9K that was working with 10.10 and an external usb wireless card.
I tried under gnome classic with nm-applet and the same problem was present: when I clic on 'enable wireless' it is disabled by the system or the application in the next second. There's no log.

$ cat /var/lib/NetworkManager/NetworkManager.state

[main]
NetworkingEnabled=true
WirelessEnabled=true
WWANEnabled=true

I fixed my problem with adding 'blacklist acer-wmi' in the /etc/modprobe.d/blacklist.conf file.
If it works your bug may be a duplicate or a new use case of the acer-wmi regression bug: https://bugs.launchpad.net/ubuntu/natty/+source/linux/+bug/710738

I have a Dell Inspiron 15N laptop that I upgraded to Natty. After the upgrade my wireless did not work. In fact, it did not even see the wireless. lshw showed the wireless as "unassigned". I went wired and completely removed KNetworkManager and installed WICD. That changed nothing. What is it about (K)Ubuntu that the developers are against wifi??? The worst part is that if I operate the button that turns on the WIFI equipment, I get a notification that it has been turned off, and, if I then turn it back on, I get a notification that it is turned on. What is that????
Why can't they get it right and leave it alone.
