Ever since the last update, my Win 7 VM network intermittently drops out. The network adapter is in bridged mode. No matter whether or not the VM is set up as DHCP or Static IP, upon startup of the VM, the network will start working for a bit, and then I see the dreaded no internet access. Leaving things alone for a while, the system will regain connectivity. This never happened before the latest update.
To troubleshoot network issue in Windows virtual machine, please follow this steps and check how it works.
