Oh, and a little more detail on why I'm certain this is related to the nvidia proprietary driver...
Part of our QA process after we image a system (before it's shipped to the customer) is to test WiFi. Since we started shipping Utopic, we've had 0% failure on systems with Intel graphics. On hardware with an nvidia GPU (for which we always pre-install the proprietary driver), we've had 100% failure when the system has an SSD for the OS drive. When the OS is on an HDD, it often works, but sometimes there are failures there too. You can work around this by going into "Edit connections" and entering your password for the wifi there. But the proper password dialog fails to pop-up when you just click on the wifi name in the indicator. -- You received this bug notification because you are a member of Ubuntu Touch seeded packages, which is subscribed to network-manager in Ubuntu. https://bugs.launchpad.net/bugs/1388130 Title: Cannot connect to WiFi with Nvidia GPU using nvidia-331, SSD Status in System76: Triaged Status in “network-manager” package in Ubuntu: Confirmed Bug description: For some strange reason, we cannot connect to WiFi on hardware with a descrete Nvidia GPU (using the nvidia-331 driver) when the system is running off a fast SSD. Swap the SSD for a platter drive, and things work fine. Likewise, on Intel GPU systems, with either an SSD or a platter drive, WiFi works fine. The failure message is: """ Connection activation failed. (1) Creation of object for path '/org/freedesktop/NetworkManager/ActiveConnection/2' failed in libnm-glib """ See the attached screenshot.
