Thanks so much Rune! My issue was similar. NetworkManager didn't have the wireless password for the network I was trying to edit.
You should be able to click save always, but there should be some sort of popup like: "Warning: Network Manager can't confirm with your router this IP address is valid. Please check the IP address you entered and/or your wireless password. Or click continue to continue with these settings." -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/737615 Title: can't save changes in "edit connections" To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/network-manager/+bug/737615/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
