A network cable is unplugged

[stankg]

Ok, I can't get on the internet on my PC (I'm on my laptop). I keep getting "A network cable is unplugged". My ethernet cable is plugged in, no doubt about it. I've tried turning my router off and back on after 30 seconds. I've tried enabling and disabling my Network Connection. I ran a diagnostic and it says:

I have no idea what all this means. Someone please help.

The one part that sticks out to me is "warn  Network adapter status not healthy" not sure if it's referring to it thinks the cable is unplugged, but I kind of wonder if the network adapter is kaput. How old is the network adapter/laptop?

Have you ever had this computer connected before? Did it just suddenly start doing this? Did the cable get moved?

It sounds like you will need to replace the card or the cable.

Also, try the cable on another computer, to the same port on the router. If still doesn't wokr, change ports on the router. a broken cable can look the same to the PC as an unplugged one.

My computer has previously been working. I've had it since 2001. It's not the cable since I'm using the same ethernet cable I use for my PC on my laptop.

If it where me, I would just replace the network card and move on.

I think the NIC is bad also....I would try to swap it out with one you know works.

here is how i solved the problem of "a network cable is unplugged", i quote from microsoft:
----from here-----
Note The steps to change this property vary depending on the manufacturer of the network adapter. In most scenarios, you can follow these steps to change the value of the Media Type property:
1.   Click Start, click Run, type ncpa.cpl, and then click OK.
2.   Right-click Local Area Connection, and then click Properties.
3.   On the General tab, click Configure.
4.   In the resulting dialog box, click the Link Speed tab.
5.   In the Property list, click Media Type or Link Speed & Duplex or something similar. Note If these properties do not appear, look for a property that has the values Duplex and Half-Duplex.
6.   Click a specific bandwidth in the Value list, and then click OK.
7.   Close the Network Connections dialog box.
8.   Test the network connection.
----to here -----

My highlight are on point no. 5 and 6, in this tab (Link Speed) there is pull-down menu 'Speed and Duplex', in the menu there are Auto Detect, 10Mbps/Half Duplex,..... and 100Mbps/Full Duplex, my suggestion is simple, try them one by one.
I had no problem with my network card, when I moved to other dorm I experienced the problem. the initial setting was Auto Detect, then I changed to 100Mbps/Full Duplex but the problem still existed. after about four months (FOUR MONTHS ) I got idea, why don't try one by one the options, finally I found that the suitable option for my laptop is 100Mbps/Half Duplex

OK here goes... a first timer!

We recently had a large electrical storm go through our area and now I have a problem with the issue above. I have a cable modem connected to a wireless router and I have 3 hardwired connections to the wireless router. I have tried 3 laptops and have wireless connection without a problem but neither of the 2 desktops can get a connection even with the cable that I verified works on all of the laptops. Is it possible that the storm took out the cards on both of the desktop computers? I was also using connections 1-3 on the wireless G router that all seem dead now, #4 is the only one that still works?? Not real educated on all of this but any help would greatly be appreciated!!!
Lost without internet in Cincinnati!!!

Yes, Buy new cards for the desktops.
If the router has one good port, get a hub for the one good port.

Or buy a new router.
