All computers on network simultaneously get "A Network Cable Is Unplugged"

[edwinemeyer1963]

In our home we have 2 hard wired home networked computers,(desktops) and 1 wireless laptop. All computers get the "A network cable is unplugged" message at the same time, and the laptop loses connectivity. We are running cable internet from TWC.
Any help would be appreciated.

Make sure that the router's power connections are in place and very secure.

Look at your router's status lights (if any) and see what they indicate. There should be explanations in the User Guide/Manual.

Look for any loose connections between the modem and router. Or if a combination unit look for any loose connections at all. Look and wiggle all plugs. Unseat and reseat to be sure they are fully in place.

I agree sounds like a power issue. Whatever switch they are connected to maybe faulty. Sometimes these new switches have power saving mode, may wanna disable that feature if it bothers you.

When the error happens, the router,(provided by TWC), goes into reset mode and the lights all flash in sequence as if you just turned it on, until the connection is made. All lights at the net plugs on the back of the router then show green as they should.
I would not think that it was an individual computer or line causing the problem since it effects every connection including wi-fi... Have considered that the problem may be with TWC itself, or their router... Never had this problem until we dropped their cable T.V and only use the cable internet now LOL...Too many internet based television options these days to pay over $100 a month for a couple hundred channels that we never watch.
The power connection seems to be secure, and all net wires are clean and secure.... Thanks for taking the time to read my question.
