Title: Ubuntu 18.04 - networkmanager dont show other wifi after few minutes Status in linux package in Ubuntu: Incomplete Status in network-manager package in Ubuntu: Confirmed Bug description: how to reproduce: dd the iso to an usb drive and boot from it. List all wifi devices in live-mode and connect to one of it. Use the web for some minutes. Open up the wifi on the top right again and list the available networks - it dont show any others any more. Just the one you are connected to. How to overcome the bug: put the computer into airplane mode and go away from airplane mode again. Or: disconnect the usb wifi device and connect it again.
