Laptops also have Ethernet ports, too, just to connect to a network that lacks wireless capabilities. An exception is the MacBook Air, which lacks Ethernet ports but can support connecting an Ethernet dongle to a USB port on the PC.

Here are some causes of connectivity problems:

  • The cable is unplugged. This condition certainly results in a network cable is unplugged error. However, the error message occurs when a PC or laptop is moved. Also, it can knock the cable out of the Ethernet port.
  • The network card is unseated. When the PC has been erased around, the Ethernet card might come unseated from the expansion slot on the motherboard.
  • Network card drivers are missing or corrupt. Something else related to the Ethernet port is the network driver for the network card. However, it becomes out-of-date, corrupt, or missing. One of the simplest ways to install a network driver is with a free driver updater tool.
