matteo, I can see nothing wrong with what's going on in the logs you added. I believe this was taken from the "server" machine which created the ad- hoc connection?
It would be helpful if you could also attach /var/log/syslog from the machine from which you try to connect to the ad-hoc network, so we know what is going on; but AFAICT here, the connection is properly established and torn down after almost 2 hours because you would have chosen a different connection in nm-applet. ** Changed in: network-manager (Ubuntu) Status: New => Incomplete -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/786368 Title: fail to connect to its own ad-hoc wireless network To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/network-manager/+bug/786368/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
