Hyper V Host Loses Network Connectivity
When you install the Hyper-V role you're essentially moving your host OS into a VM. Let's start from that, checking your virtual switch situation. For me the issue turned out to be the Network Card driver had Priority and VLAN disabled. share|improve this answer edited Sep 22 '11 at 19:16 answered Sep 22 '11 at 17:52 Mike 5843927 add a comment| up vote 1 down vote On the network adapter properties for this contact form

Hyper V Network Connection Issues My theory is that the problem you are running into is with Windows 10 rather than with Docker or Hyper-V.
One would go down, and others on the same external Hyper-V switch would function just fine.

My server has Broadcom NetExtreme NICs, so it seems for me the cause of this issue was definitely driver related, but setting DisableTaskOffload = 1 resolved the issue completely for me. We removed that setup and configured one of the nics so it had no IP at all on the host machine, but could still be used for passthrough to virtual guests.

When I create a new virtual network switch, external, it bridges the VMs network adapter with the WiFi - and that for some reason kills the WiFi's internet connection. Communication is via the motherboards' integrated NICs which are Intel 82574L. I can close the switch dialog and start the service, but I clicking on the virtual switch manager again kills the virtual machine management service. If the above does not work for some reason, a software that might be able to help is Connectify Hotspot (shareware/paid), which via its Virtual Router can share WiFi as Ethernet.

I've also had it "just work" after having left the machine on for some time so I suspect it's a timing issue somewhere deep down in the virtual hardware stack.

You could try into virtual switch's properties on the host machine and changed some adapter properties for the virtual switch, then changed them back to default and within seconds of hitting
Of course that means no failover if an adapter or connection goes down, and we haven't followed through well to see whether traffic has remained balanced over time, but it's been Although in the Hyper-V Manager screen tells me that the virtual machine is running and a small thumbnail like image at the bottom of the Hyper-V Manager seems to show the
