So I wanted to make my laptop a second monitor for my PC. But it didn't work, so I searched on YouTube about how to do it and someone said that I needed to reset my network, so I reset it and after that I couldn't connect to my network on device manager. It shows a yellow exclamation triangle. And at other devices have the same triangle. My network adapter is Intel(R) Ethernet Connection 1217-LM. Please help me.

On network adapters, it says Windows is still setting up the class configuration for this device. (Code 56) and, on other devices, the PCI serial port has the yellow triangle and the other 2 too.

That indicates there are many drivers not installed on your PC, that PCI device would be related to the chipset device drivers, try downloading and installing them, then try re-installing the network card device driver again.
