The network adapter couldn't be located. If deep sleep is active, make sure to connect the cable.
I purchased used components and assembled a computer. It was functioning properly at first. I was using an Ethernet cable and had internet access. The following day I lost internet connectivity with the cable, and the network adapter disappeared from the device manager. Before this issue occurred: 1. I installed and activated Norton. 2. I received a Windows update. My motherboard doesn’t support Wi-Fi, so there’s no internet connection. When installing drivers on another machine, I received an error saying the Realtek Network controller wasn’t found. If deep sleep mode is active, please plug the cable in. I then bought a TP-link Gigabit network adapter PCIe (TG-3468), but my motherboard still doesn’t recognize it and I’m unsure how to install drivers for it. Any help would be appreciated. I’ll add pictures to the comments with my screenshots: GIGABYTE GA-AB350-Gaming 3 Ryzen 5 1500x GTX 1060 6GB 16 GB RAM. Instead, I got all these mini ports but no recognized network adapter/controller. https://imgur.com/a/z7zgPtC
The wan miniports come from the VPN, and unplugging then plugging back in the cable resolves the issue. It seems like a BIOS power-saving mode is shutting down the interface.
Have you reviewed computer management settings? Locate your adapter, open properties, then go to power management. Check if BIOS and the driver are current. For the TP link, did you receive a CD with the driver? If not, attempt to download and install it.
