I just bought a new Dell Inspiron 5570 (Windows 10 Home, 64-bit). But when I have a wired connection, it keeps dropping out (don't have this problem with a wireless connection) and reconnects in a second. 

I have tried the following fixes:

- netsh fix method

- Update the network adapter software (manually and automatically)

- Windows Update + BIOS Update

- Put the wire inside another port of my router

- Uncheck the "Allow to shutdown this hardware for energy saving"

Anyone got any other ideas what I could try to fix this? It's really problematic, because my VPN to work disconnects as well, every time.

My ethernet adapter is: Realtek PCIe FE family Controller

Thanks!
