A couple of suggestions, 1st one first, both together if required -

Those who have both a good level of theoretical knowledge as well as practical experience recommend channels 1 and 11 the most. So try them first.
Try Wicd and remove Network Manager altogether exactly as per steps given here : https://help.ubuntu.com/community/WI...e_.2BAC8_Unity
Please note that you won't get the tray icon on the top right corner like network manager. Wicd does not have that. It needs to be opened from Applications menu like other normal applications.
Use the commands in my previous post with wicd as well if required.
Everything else looks good.
