Broadcom Device BCM43142 Wireless Driver for Ubuntu 14.04 LTS 64Bit Desktop not working out of box

$ lsb_release -rd
Description: Ubuntu 14.04 LTS
Release: 14.04

$ apt-cache policy network-manager

After installing Ubuntu 14.04 Desktop version 64 bit on my Dell Vostro 2520 Laptop, I expected the wirless card to automatically be detected and to be able to connect to any wireless network for seamless internet access.

However, the driver for wifi did not get automatically installed. I looked around for some information in the web and found a blog suggestion to run the following command for wifi to work:

$sudo apt-get install linux-headers-generic build-essential dkms

After running this command, I found the driver to show up in the right corner, but when I select a wifi network, I saw another error:

(1) Creating object for path '/org/freedesktop/NetworkManager/ActiveConnection/2' failed in libnm-glib.

I tried asking in the freenode ubuntu irc chatroom but did not get any solutions.

After trying out several suggestions from the chat room, nothing worked.

Workaround:
Finally, through nm-applet I clicked on "Edit Connections" and selected the wifi network I was trying to add. Then in the security settings, I typed the password for accessing the wifi and configured it.

When I unplugged my LAN and restarted wifi, it worked. Now I am able to access the wifi.

The forum member in Ubuntu chatroom suggested I file a bug:

To summarize the issue is, there is no inbuilt driver for Broadcom BCM43142 Network Controller.

Please help fix this in the next update. Let me know if you need any further information.

Thanks
Sharath

Status changed to 'Confirmed' because the bug affects multiple users.

Ubuntu 14.04 x64 Lenovo B590, broadcom bcm43142- Not work.

[Stephen A. Goss (postfuturist)]

After updating from 13.10 to 14.04 I get the same error attempting to connect for the first time to an encrypted wifi connection:

(1) Creating object for path '/org/freedesktop/NetworkManager/ActiveConnection/9' failed in libnm-glib.

This is my device:

02:00.0 Network controller: Intel Corporation Centrino Wireless-N 1030 [Rainbow Peak] (rev 34)

My lenovo E330 shows the same error behaviour as described by Stephen A. Goss.
Since updating from 13.10 to 14.04 I sporadically receive:
"(1) Creating object for path '/org/freedesktop/NetworkManager/ActiveConnection/7' failed in libnm-glib" on connecting to a radius /EAP-TTLS-authenticated network.
Side effect: the (previously saved) password vanishes from the settings dialog....

My wireless lan adapter is a:
02:00.0 Network controller: Intel Corporation Centrino Wireless-N 2230 (rev c4)

The error does not occur on another laptop with 14.04 and an ath9-based pccard.

My WiFi connects, but I don't have Internet. I have this error since Ubuntu 13.10, and without solution.

I am usu dell vosro 25520 ubuntu 14.04.
but my laptop blutooth driver does not working...

[Ofer Cohen (oc666)]

I've encountered the issue and to solve it I just run the next command:
# sudo rmmod b43 && sudo rmmod bcma && sudo rmmod wl && sudo modprobe wl && sudo modprobe lib80211_crypt_tkip

It seems that b43 or bcma are collisions to the wl module.

[Ofer Cohen (oc666)]

One fix to the command:
(sudo rmmod b43 ; sudo rmmod bcma ; sudo rmmod wl ; sudo modprobe wl ; sudo modprobe lib80211_crypt_tkip)

[David Balažic (xerces8)]

Ofer, is that a fix for the missing driver or the "Creating object for path" issue?

I also have the second problem on a 14.10 live system.

Probably a new bug should be opened for that issue.

There is some info (and workarounds) about it here: http://askubuntu.com/questions/469783/ubuntu-14-04-cant-connect-to-new-password-protected-wifi-network
