Ubuntu: 14.10 Wi-Fi connection problem



Question:

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.

Thanks.


Solution:1

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


Solution:2

  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.
