I don't see why the DNS plugin in NetworkManager would make any type of difference with wireless authentication. Please don't recommend such changes if it's not relevant to the problem at hard.
The most information we have here is the reason 8 messages just before the CRDA domain gets re-updated. This is a clue to look into, since it means "Disassociated because sending STA is leaving (or has left) BSS" in other words, the client is leaving the access point for some reason. To further debug this, we'll need wpasupplicant logs. Please run: sudo python /usr/lib/NetworkManager/debug-helper.py --wpa debug Then see if you can reproduce the issue. This will add debugging information from wpasupplicant to /var/log/syslog; so once you can reproduce the issue with this enabled, please attach the file /var/log/syslog to this bug report so that it can be reviewed by a developer. Thanks! ** Package changed: network-manager (Ubuntu) => wpasupplicant (Ubuntu) ** Changed in: wpasupplicant (Ubuntu) Status: Confirmed => Incomplete -- You received this bug notification because you are a member of Desktop Packages, which is subscribed to network-manager in Ubuntu. https://bugs.launchpad.net/bugs/999977 Title: WPA2 Authentication Requested Multiple Times Status in “wpasupplicant” package in Ubuntu: Incomplete Bug description: 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).
