Additional information: I ran dpkg from the recovery menu. I'm uncertain whether that's caused the following behaviour or not.
On logging in, network manager shows "[wireless card name] disconnected" On turning off wireless with the function key, network manager shows "[wireless card name] device not managed" On turning on the wireless using the function key, network manager shows "Enable wifi" box unchecked. Checking the box allows the machine to connect to the router. If I turn the machine off, or reboot, I have to go through the last three steps again. -- 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/1569590 Title: wireless card disabled in network-manager Status in network-manager package in Ubuntu: New Bug description: Using xenial on Asus EeePC 900 Network manager has worked fine with the wireless card on this machine, until the update of 12 April. Now the wireless card appears greyed out in the nm-applet interface with no SSIDs visible. Ethernet still works. wicd works on this machine, but I'd prefer not to have to install that.
