Public bug reported:
Connecting to the WiFi LAN the first time when the PC has booted up with
Ubuntu 12.04 is ok. However after a while there is a disconnection from
the LAN. When network-manager attempts to reconnect it takes a long time
before a WPA2 authentication dialog pops up asking for the password.
After a while the same dialog pops up multiple times even though the
dialog popped up the first time.
When entering in the correct password to connect to the LAN via the
dialog, network-manager takes a long time to connect but pops up with
the same dialog again. No network connecion is ever made. A temporary
workaround is to disable networking and re-enable it again from the
network-manager applet. However if another connection needs to be made
to the LAN then the same problems occur, and the workaround must be used
again.
This authentication issue is serious and if the workaround no longer
works then the problem becomes a critical one. Noticed the same problems
occuring on other PCs running Ubuntu 12.04, which use a ralink wireless
chipset. It appears as though this problem affects all Ubuntu 12.04 PCs
that use a ralink wirless chipset for WiFi networking.
In the previous Ubuntu LTS version (10.04) the authentication problem
rarely occured. Initially in Ubuntu 12.04 it was like Ubuntu 10.04 but
after some updates then authentication problem has become much worse
(huge regression).
