Macos mojave 10.14.6
intermittent disconnections from Wifi And/or hardwired connections
restarting laptop progress bar hangs about 5 seconds at about 75% completion. Usually soon after a restart network capabilities are accessible but after 5-10 minutes there is no accessibility. Wireless diagnostics shows network accessible during troubleshooting
In case anyone reads this thread, the following is what cleared my issue:
1.) Settings, Network, Advanced, choose WIFI and move your wifi network name to top of the list
2.) Resetting the NVRAM/PRAM
3.) Restart Laptop
3.) Settings, Network, Advanced, choose Proxies, changed my selection from SOCKS Proxy to Auto Proxy Discover

Looks like a startup disk age problem.
