Have you had the same issues with me? When you have turned on Hyper-V feature and setup with one or multiple VM instance on your laptop, then when you tried to access webpage via browser or download anything it just very slow than it normally do. Well, more specifically if you have created an external virtual switch in order to bind your host’s physical network adapter to the VM instance to access the Internet. (see the below screenshot that created another network adapter named “vEthernet(External) and Bridge”).
This is somewhat frustrating when you do have decent network performance (I mean both the computer and network part) then you just keep getting slow speed… Sometimes this just hard to find out when people who play Hyper-V with a mobile workstation with high performance, but when realize that you shouldn’t have such low speed you have to take a while to figure it out. You may just like to me try to checking your network connection and the router…etc. But everything just fine without error.
So, since the issues is related to the virtual switch that I’ve created in the Hyper-V then the solution is quite simple: Remove the “External” virtual switch!
After I did that everything just appears to be normally, I mean especially my network speed!
Please do know that is a trade off if you are setup Hyper-V on a laptop, if you are like me only have one network adapter card on the laptop then just temporary remove and re-create it back when need. Unless your laptop had a second network adapter card (usually the Ethernet one) that you may bind with one of these network adapters.
One more thing, please do not forget to edit the effected VM instances which to change the virtual switch to “Private” or just “Not connected” in case you cannot start the VM instance and received with scare error message.
