ping a device on my network by its local IP. When the device is logged out (at lock screen), I get a wall of "Destination Host Unreachable". When the device is logged in, the pings return just fine. Remote is 16.04 Ubuntu MATE on a Raspberry Pi 3, via Wi-Fi. I originally thought I was having a
ssh issue with home encryption, but I realized it's a general networking issue.
I could use your help determining whether this is a hardware or software setting issue.
