I was just checking the network utilization in the task manger and discovered that it is showing wrong information. Please see the screenshots:
I was using wifi to update my system. When I checked the graphical representation, I found the above shown information. The graphical representation is not accurate. It was showing wifi usage graphic under Ethernet(VM) connection and vice versa.
Also under the process tab I found the network utilization shows 0% while my wifi was receiving data at a rate of 7Mbps approx.
