My Windows 10 computer is not connecting to the ethernet cable. It's is a HP device and happened randomly overnight. I went to device manager and Natwork Adapters is not showing on the list. I guess that disappeared too. There is a yellow triangle on PCI Serial Port and PCI Simple Communications Controller. What do I do????My Windows 10 computer is not connecting to the ethernet cable.
