Question about Network Software & Management Tools
The most likely culprit is the cable you are using to connect the desktop to the router.
The networking icon with the red X is your computer telling you the network card is not physically connected to a functioning port. Either the cable is bad or one of the ports (your computer's or the router's) has a physical or electrical problem. Try using the laptop cable and/or connecting to the port the laptop is connected to.
If the problem is something else, it is likely more information will be needed to diagnose and fix it (router model, OS version, whether a DHCP server is running, the network address of the router, the exact type and text of the icon that's telling you the network is disconnected).
