Network cable unplugged

10 New Member
Hi All,
I have a lenovo 3000G/410 notebook ,yesterday and day before yesterday i was surfing the net using it and it was running for more than 36 works continously.Aft er that when i unplugged the network cable and again connected after some time then it does not gets connected.The network cable unplugged error is being shown but the cable is fine as my friends are able to connect to internet using that same cable, but i am not.The light at the end of the cable to which we plug in to the system also doesn't glows.

So,please let me know what could be the problem, fearing the worse , did there be some problem with the network card inside the laptop which might have been damaged because of such prolonged use.

Need Help Urgently.

With Regards

Hello litusahoo!

First of all, what Operating System are you using? (e.g. Windows XP, Ubuntu Hardy Heron or OS X Leopard) Please give this information in any such question.

Now, as you probably use Windows XP or Windows Vista, I'll try to help you with those.

First of all, you see the "network cable unplugged error" as you call it. Click on that with the right mouse button and you'll get a menu. Choose "properties " or "settings" or whatever it may be called - it should be fairly clear.

Next, deactivate the network connection. I know, this sounds weird, but just try it. Now, if your network cable is connected, take it out and plug it back in again. If it isn't, just plug it in. Make sure, it is in the socket properly (and that there's nothing else in the socket!), then reactivate the network connection by the same route as you deactivated it.

If it works, the light at the network socket should switch itself on, when it's trying to make a connection and stay on, when the connection exists.

In general, every part of a computer can break, but it's not very lightly, that the network card just broke after working fine for 36 hours and then switching the machine off. I assume, the connection just has to be re-established.

Greetings,
Nepomuk

OK, I've not worked with Vista much, but I'm guessing, it's similar to what I described for Windows XP.
If you can't find something I described in my instructions, try the following route:

Open "My Settings" (or whatever it's called)
Choose "Classic View" (or similar)
You should have a Symbol called "Network" (or something like that) - open it.
Find your network card, choose it and click on "settings" or "extras" or whatever.
Deactivate the network card.
Dis- and reconnect the ethernet cable as described in the WinXP instructions in my first post.
Reactivate the network card.

Now, if it still doesn't work, we'll have to think of something else. In that case, choose "Start" -> "Run". Type "cmd", click "OK" and a DOS-like window will open.
Here, type ipconfig /a and press Enter. Then post the output here. (Please use the code-tags to post the output.)

It rather sounds like your NIC card is damaged. I do not believe it was from prolonged use. 36hours is really nothing. 36days is really nothing. If you went 36months with heavy traffic MAYBE you could damage something.

Is the card built into the laptop or removable? Removable ones are more prone to hardware failures.

Was there any power issues? Weather? Lightening could short out your card.

Hi, I have the following situation. When I unplugged the network cable from a running ethernet card in a Linux box, there has no sign telling me the cable is unplugged from the system perspective (unless I try to perform socket connect). Does any one know how to accomplish this in C++? The reason behind this is I need to know if the connection is available for that particular network card in the application. Any help is appreciated.
