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) -- You received this bug notification because you are a member of Desktop Packages, which is subscribed to network-manager in Ubuntu. https://bugs.launchpad.net/bugs/1315265 Title: Broadcom Device BCM43142 Wireless Driver for Ubuntu 14.04 LTS 64Bit Desktop not working out of box Status in “network-manager” package in Ubuntu: Confirmed Bug description: $ lsb_release -rd Description: Ubuntu 14.04 LTS Release: 14.04 $ apt-cache policy network-manager network-manager: Installed: 0.9.8.8-0ubuntu7 Candidate: 0.9.8.8-0ubuntu7 Version table: *** 0.9.8.8-0ubuntu7 0 500 http://in.archive.ubuntu.com/ubuntu/ trusty/main amd64 Packages 100 /var/lib/dpkg/status 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 $ lsusb Bus 002 Device 002: ID 8087:0024 Intel Corp.
