I have been experiencing an issue with my Windows 11 system, where the network connection is lost after sleep mode. Upon reinstallation of the network adapter driver, I received the message 'The Realtek Network Controller was not found if Deep Sleep Mode is enabled, please plug the cable.' I checked by removing the mainboard battery and closing the option to save power by turning off the device, but the issue still persists. Does anyone know a solution to this problem? I am extremely frustrated.
