[Bug 1475042] Re: ubuntu 15.04 wireless network driver doesn't connect: always "trying to connect" animation
** Description changed:
-
I'm using Ubuntu 15.04 after the network upgrade 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 and display them, but when i try to connect with
- one of them, Network-manager ALWAYS display the "connecting..." animated
- icon and doesn't connect (i can't access to internet and not even to my
- Access point admin page).
+ With Ubuntu 14.10 the wifi connection was ok.
- 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).
+ 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..." animated icon and doesn't connect (i can't access to internet and not even to my Access point admin page).
+ Opening the network-manager menu show the "Disconnect" menu entry (like when you are connected, but you are not connected).
- Using Ubuntu 14.10 the wifi connection was ok.
+ The cable connection (eg: eth0 interface ) works.
+
+ My access point (Digicom Michelangelo wave 150 C) uses wpa2 encryption.
+ I haven't done no harware modifications (i use the same builtin wireless network card provided by my notebook).
Using the same wireless access point, but with another notebook (Toshiba
Tecra with Ubuntu 14.10) everything is ok.
- The cable connection (eg: eth0 interface ) works.
+ I have tryed to disconnect/reconnect the wireless, reinstall the
+ network-manager.. but with no results.
- Trying to disconnect and reconnect the wireless, delete and recreate the
- network, reinstall the network-manager and network-related packages the
- problem persist.
-
- While the network manager shows the "connecting..." animated icon,
- opening the network-manager menu show the "Disconnect" menu entry (like
- when you are connected, but you are not connected).

+ ------ Imortant: -------------------
I have discovered that the "Additional Driver tool" allow to enable/disable an additional driver named "Processor microcode firmware for intel CPU (proprietary)".
I have done a test running a fresh ubuntu 15.04 live cd: i can't connect
to wireless, but enabling the above Intel driver i can connect !
Repeating the same test with the installed ubuntu 15.04 i was able to
connect only a couple of times (i have tryed to enable/disable the
driver after a kernel update from the Ubuntu update manager, but with no
result).
- Disabling the Intel driver happen the same situation described above
- (ie: always "trying to connect")
