Today I managed to solve this problem: I had once deactivated the KDE Wallet subsystem. I enabled it again, restarted the system, and the network manager started connecting automatically again.
However, I want the computer to connect without asking anything (I'm not always near it). But now it asks for my wallet password... I solved it by entering a blank password, but that's a workaround. I've always disabled the kde wallet subsystem without a problem. Problem solved, I want to share some thought about this issue.: I can't help but saying that I seriously can't believe that this bug is still present, with medium priority and assigned to nobody. If this bug was present in windows (and for a year!), everyone of us would be making jokes about it. A whole release came and gone without anybody interested in solving this. It's really unbelievable. Please don't tell me to upgrade because I use the computer for GPGPU and Plasma 5 breaks when installing nvidia proprietary drivers (so 15.04 isn't an option for me) and 14.04 *LTS* has another open bug that prevents it for being used for GPGPU with nvidia cards. So, I'm just thinking about changing OS. Not caring about bugs is a serious issue these last years in *Ubuntu. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1354924 Title: Networkmanager does not autoconnect to wireless network To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/network-manager/+bug/1354924/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
