A Network Cable Is Unplugged Error Message



This message appears as a Windows desktop balloon. If your connection is wired, you may lose access to the network. If your connection is wireless, your network will probably function normally, although this error message will become an annoyance as it pops up repeatedly until the issue is addressed. Several different conditions can generate this error each with their own solution.
Answer: Several possible causes of "A Network Cable Is Unplugged" messages exist. The error message appears on a computer when an installed Ethernet adapter is seeking to make a network connection.

Try the following tips to resolve your problem:

- Disable the Ethernet network adapter if you are not using it. This applies, for example, when running a WiFi home network with computers that have built-in Ethernet adapters. To disable the adapter, double-click the small Network Cable Unplugged error window and choose the Disable option.

- Check both ends of the Ethernet cable connected to the adapter to ensure they are not loose.

- Replace the Ethernet cable with a different one to verify the cable is not damaged.

- Update the network adapter driver software from the manufacturer's Web site.

- Change the Link Speed and Duplex settings (using Device Manager) to use "100 Mbps Full Duplex" or "10 Mbps Full Duplex" instead of Auto Detect.

- Replace the Ethernet network adapter if it is a removable PCI or PCMCIA card. First remove and re-insert the existing adapter hardware to verify the card is connected properly. If necessary, also replace it with a different card.

- The device your Ethernet adapter is connected to, such as a broadband modem or network router may be malfunctioning. Troubleshoot these devices as needed.
