If your network adapter shows up in the Device Manager but doesn’t show up in the Network Connections, try to uninstall and re-install it. You may need to check your NIC on another computer (if possible) or check its functionality at the service center (it may be broken). Then check that your network card is physically connected to your computer/laptop and is enabled in BIOS/UEFI settings. If the list of network adapters is empty and there are no unknown devices on your computer, search for the devices in the Device Manager (Action -> Scan for hardware changes). The device manager in safe mode will display a list of categories representing your hardware devices, such as Display adapters, Network adapters, Sound. Thus, you can identify your NIC, download, and install its driver. For example, PCI\VEN_14E4&DEV_43A0 is Broadcom wireless network adapter. In HWinfo it detects my GPU but some info is unknown. I am unable to install the drivers for the gpu as device manager wont detect it so nvidia thinks I dont have a GPU. The GPU is actually on in my pc with the rgb working and fans spinning. Find the VID and PID of the unknown device (Properties -> Details -> Hardware IDs). The GPU is listed as 'PCI Device' under other devices in device manager. If Windows could not detect a device, you need to identify it manually. Highlight Network adapters, then click Next. Select Search for and install the hardware automatically (Recommended), then click Next.
Windows should detect the device and install the appropriate drivers. Right-click on Start menu button and open Device Manager. Try to perform an automatic driver search.
Make sure that automatic driver updates is enabled in Windows.
