I installed Ubuntu the day before yesterday and am still having a few teething issues.
Every half hour or so my wireless connection just stops, but is still indicated as online. Disconnecting and reconnecting solves it for once but its becoming a major pain.
Several times when I disconnect it takes two tries to reconnect and I get the message
creating an object for path"/org/freedesktop/NetworkManager/ActiveConnection/8" failed in libnm-glib
I am an absolute noob when it comes to all this at the moment, so please speak slowly.
I am on Ubuntu 15.04 and the output from terminal command
lspci -knn | grep Net -A2
is
