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.
