I had enabled Hyper-V. I experienced frequent blue screens due to conflicts with NOX emulator. I deleted them and no longer got blue screens, but I still decided to disable Hyper-V back(I did not create any virtual machine). Then my internet stopped working. I am getting packets, just no internet.
- I am using static IP address in a research environment. Looking at the ipconfig /all, using any of the available(&reserved for me) IP address for my Ethernet adapter would mark it as "Duplicate". Not sure if this is the core reason, but I tried what I could.
- Would some unknown adapter using the same IP address? I tried uninstalling network adapters in Device Manager. Also scanned for hardware changes to bring them back.
- Should things be 'properly' cleaned up using Hyper-V Manager? I re-enabled Hyper-V, created virtual switches and deleted them. I reset the network with netsh command, both before and after disabling Hyper-V back. No luck there.
- I finally resorted to reinstalling Windows. It didn't solve the problem. Did Hyper-V just mess up my firmware or something?
