I have broadband internet connection, I always shows disconnected with Red cross mark. I Changed another Ethernet card but problem is still same. Light is showing onto MB when I connected to LAN port.
Is there any virus or MB defection ?
If you can connect with usb, then it means that your cable/s may be broken, or the port/s on the router may be faulty, or your network card itself. When you connect a cable from your pc network card to one of the ports on the Dlink, can you access the router gateway?
