I recently started to experience problems with my Wi-Fi. I have Ubuntu 14.10 on a Dell Inspiron N4110. I recently began experiencing problems with my Wi-Fi. It would take randomly to stop and disconnect (According to Google Chrome), even though it showed that it was connected (According to Ubuntu). It also showed me a message " (1) Creating object for path '/org/freedesktop/NetworkManager/ActiveConnection/6' failed in libnm-glib. I am relatively new to Ubuntu and so if you want me to do Terminal, please also explain so that I may learn.

I saw this on another forum and so this may be of help to you. I ran "sudo lshw -C network" in Terminal and this is what I got.

  • @CharlesGreen Thanks for editing it. Copying and pasting messed it up.

  • No problem. Copy, paste, hightlight pasted data and press ctrl+K to make it all into a code block... Nov 16, 2014 at 1:54
  • Have you tried disabling ipv6? Nov 16, 2014 at 1:55
  • I know Ip6 and ip4 have to do with Wi-Fi but that is all I know about them.

You could try disabling ipv6, and see if this helps. Ipv6 is a newer internet addressing protocol, and sometimes older hardware and software seem to get a little bunged up by it, for no apparent reason.

To disable Ipv6, open a terminal window (alt+ctrl+t) and enter the following command

sudo nano /etc/sysctl.conf

This will open an editor to the file sysctl.conf. scroll to the end, and enter the lines

net.ipv6.conf.all.disable_ipv6 = 1
net.ipv6.conf.default.disable_ipv6 = 1
net.ipv6.conf.lo.disable_ipv6 = 1

Save the file by pressing ctrl+o, and exit by pressing ctrl+x. You can then force the load of the modified file by entering the command sudo sysctl -p

To revert to what you had before, edit the file again, removing the added lines, and reboot

  • It seems good for now but since the problem seems to be on and off, I will have to see over time. I don't need to reboot for it to activate, right?

  • If you did the sudo sysctl -p then it loaded the parameters and you do not have to reboot. Nov 16, 2014 at 2:59
  • Thank you. Everything seems fine. I will just have to wait and see.

  • It seems that my Wi-Fi just gets super slow in the late evening (8 and up).

  • It seems that my WiFi works fine, even though I am not doing what you said. Perhaps my network was just being slow for a couple of days or so. Thank you for your time and effort

  1. Go the Edit connection tab, a list will come up with all the connections.
  2. Select the network connection you want to select.
  3. Input password.

This works for me, although this is not a permanent solution.
