Hello, A time ago my motherboard died so I decided to buy a new one. After installing the new motherboard I turned on the laptop and flashes the BIOS to enable Intel AES-IN. It worked like a charm, but……. the REALTEK LAN card can’t be found. No wired internet connection. The strange part is that the USB 2.0 port on the LAN board works. How could it be that the LAN port isn’t working?? Tried another LAN card (same as the origin) but same problem. USB 2.0 port works and the LAN port not. Can’t find the REALTEK LAN card in device manager and ipconfig/all gives me ‘no device connected’. Has it something to do with the BIOS flash or have I bad luck and are both LAN cards to hardware heaven?
