Error: Connection activation failed: No suitable device found for this connection

glad to be on these forums! I searched around a bit on the forums, but couldn't find a good pre-existing case for this that might resolve anything. The error just happened out of nowhere after a boot-up, but I do have an "enp" type wireless device name listed at "DEVICE=" in a file named "ifcfg-[my own device name]" which can be a problem if not the case, so what happened here? When I run "systemctl restart network", I get: "job for network.service failed because the control process exited with error code". 1) Restarting anything does no good for anything. 2) I haven't tried re-installing anything - yet. 3) "ip add flush [device name]" does nothing, says my device doesn't exist. 4) Pinging 127.0.0.1 gives response. At one point, I got this message too: "failed to start lsb bring up/down networking" What suddenly happened here? I'm on a fedora30. Thx for taking the time to read this. RX
