Problem WIFI strange

Hello, I need help for a very strange problem. Indeed, when connecting to the session, my wifi is done and is functional! But if I ever want to switch networks (so I disconnect from the current network, and select another). From the impossible! it will turn in a loop and tell me you are disconnecting! Why does it work only at the start of the session? The connection is no problem, but if I change network … more way even to return to the one that worked … I use network manager.

EDIT : I am forced to restart network manager … and it works again via: sudo /etc/init.d/network-manager restart WHY ? how to work around this problem ?

Hi Anthony,

what version of UM do you have?, what are your software settings like?:
