More “A Network Cable is Unplugged” Errors!?
I have a desktop PC, Acer laptop, cable modem, and a Linksys wireless router (WRT54G). I connected all the hardware correctly to create a small home network.
The wireless connection to my Acer laptop runs perfectly. Meanwhile, the PC connection to the router, via an Ethernet cable, has begun disconnecting, with the error message “a network cable is unpplugged” appearing in the Windows taskbar.
Everything is plugged in and I’ve gone through several troubleshooting steps, including chaging Ethernet cables and configuring the network adaptor (10Mbps/Half-Duplex).
Even more odd, I was playing a first person shooter game and once I exited the game, the network cable is unplugged message suddenly appeared. At the back of my PC, I unplugged the Ethernet cable, waited 5 secs, and then plugged it back in. The connection was re-established!! The network adaptor’s lights started blinking again.
Is it my PC’s network adaptor or my router or my cables??
Thanks for your help!
That error indicates a physical connection problem – it is NOT a layer 2 IP addressing problem or anything software. ‘Network cable unplugged’ means exactly that – your PC has lost a physical link to the router.
Either you have a dodgey ethernet cable (most likely), or your LAN card is damaged. It’s also possible the port on your router is failing, replace the cable, and use another port on the router to rule out the last 2, as for the LAN card, you can buy cheap PCI ones (though LAN ports rarely fail).
