This problem symptom remains after reboot the VM image and even after reset, disable, re-enable back, and repair the network adapter. However, Bridged Autodetect is working.

Resolution:

Step 1: Open Terminal.

Step 2: Execute the following command to restart the networking service:
sudo /Applications/VMware\ Fusion.app/Contents/Library/vmnet-cli --stop
sudo /Applications/VMware\ Fusion.app/Contents/Library/vmnet-cli --start

Remark: A bug in Fusion 10.1.* that breaks the DHCP service on suspend-resume found. Reverting to older versions of VMware Fusion fixes the issue regardless of the macOS version. Do make sure you have updated the VMware Fusion to the latest version at least 10.1.3 (9472307) and restart it after the update completed.
