I return my older computer (windows 7 Home Premium) to factory condition, everything seem to work fine but when I tried to go on the internet from a Ethernet connection (no wifi on desktop), it says "no connections are available". I went to Device Management and notice the Network tab was missing. how can i fix this issue?
