I’ve had exactly this problem from time to time in Fusion recently. A quit and start of the Fusion app was required to fix it. If I’m seeing the same problem as this then there is a fix so you don’t have to quit and start Fusion. The OP is running Fusion 7 on macOS 10.13.4 which isn’t supported.
I’m running Windows 7 in VMWare Fusion 7.1.3 on a Macbook OS 10.13.4. I’ve been running Fusion for years. Right now the network connection is not working when I’m in my office. In Windows I get a 169.xx.xx.xx IP address and “no internet connection” when in bridged connection.
I’m running Fusion 10.1.2 on macOS High Sierra 10.13.6 and see this problem from time to time. The command to restart the Fusion netcli is:
sudo /Applications/VMware\ Fusion.app/Contents/Library/vmnet-cli –start
sudo /Applications/VMware\ Fusion.app/Contents/Library/vmnet-cli –stop
sudo /Applications/VMware\ Fusion.app/Contents/Library/vmnet-cli –configure
Note that the above lines are wrapped because bleh.
