macOS 10.13.6 will not automatically connect to LAN at startup
macOS 10.13.6 (updated yesterday from 10.13.4) does not connect to local network at startup. And stopped connecting before OS update.
Connecting to LAN using System Preferences/Network and exiting with ‘Automatically join this network’ enabled (clicked) but is not enabled at subsequent shutdown/logins.
Other Mac (10.13.6) on same network automatically connects as do several iOS devices.
All devices are wirelessly connected. with Airport Extreme. Seems this issue began around the time of addition of 2 HomePods to network.
