[Bug 1475042] Re: ubuntu 15.04 wireless network driver doesn't connect
** Description changed:
- I'm using Ubuntu 15.04. After upgrading from 14.10 the wireless connection doesn't work on my Notebook Acer Travelmate 5720G
- Network Manager scan and find successfully all the available wireless networks on start-up, but when i try to connect with one of them, Network-manager ALWAYS display the "connecting..." animation and doesn't connect (i can't access to internet and not even to Access point admin page).Seem that it try to connect but can't do it, also waiting for a long time.

My access point (Digicom Michelangelo wave 150 C) uses wpa2 encryption and i haven't modified it, also my notebook hardware
configuration is not changed (i use the builtin wireless network card provided by my notebook: no external card).
- Using Ubuntu 14.10 the wifi connection worked correctly. Also, using the same wireless access point, but with another notebook (Toshiba Tecra with Ubuntu 14.10) i have no problems, everything is ok.
- Using the cable connection (eg: eth0 interface ) everything works.
- Trying to disconnect and reconnect the wireless, delete and recreate the network, reinstall the network-manager and network-related packages the problem persist.
- A strange thing is that the network manager shows the "connecting..." animation but opening the network-manager menu show the "Disconnect" menu entry (like when you are connected, but you are not connected).
