Since updating to release-juno, from release-loki, the wifi disconnects after a period of time (around 15-20 minutes).
I'm using a Toshiba Satellite. I've checked the power settings, and when plugged in the machine is set to never suspend. I didn't have this problem on Loki, so I'm assuming it's a setting I'm not seeing in the Settings, or can be solved by command line.
