Hi. I've been wanting to use my Ethernet cable -it has plug-ins on both ends- and tried to connect my laptop to a modem or router, but I look at my Control Panel saying it's not plugged in. I don't believe the plug to be broken because it was rolled up and twist-tied when it was found. I tried the diagnose but it said it needed to be fixed or not properly plugged in. The plugs are inserted correctly and like I said: I don't think it's broken. I updated the driver unless I need to restart my laptop to make sure it works and I'm using the Realtek PCIe FE Family Controller and upgraded to Windows 10. I looked at videos and certain forums that had this problem and there were links but only selected certain links, and I still don't know what's wrong. Is there any ideas that could work? Thank you.
