Bridging Hyper-V virtual network and physical network kills physical network connection [closed]

Stop trying to bridge the Virtual Switch adapter with ANY of the physical network adapters in the host. That's not how Hyper-V networking works and is no doubt the cause of your problems. The correct way to implement networking in Hyper-V for VM communication that needs to occur between the virtual machines and the rest of the external network (the network beyond the Virtual Switch) is to create an external Virtual Switch on one of the physical adapters on the host, preferably a NIC dedicated for Virtual Machine communication. If you only have a single NIC in the host then that can be used for both host communication and for VM communication, although it can't be a wireless NIC.

Internal network can only talk to each other and to the host. You can't connect such a vswitch to an Ethernet adapter. The correct option is to use an "external" vswitch type.
