This sometimes causes mDNS to fail when host and device are connected to public wifi.

From: #46698 @dnfield says:

When hotspot is enabled, we don't get a link local adaptor. And by default, when I'm otherwise connected, that adaptor is disabled. We should look to see if there's some way we can enable that adapator (I'm thinking something like either ifconfig up or defaults should be able to control that somehow).
