Network cable unplugged but isn't [Solved/Closed]

Ask a question Kerri - Last answered on Aug 31, 2017 at 08:33 AM by hitesh
I'm not exactly sure how to describe it, but no matter how many times I unplug and replug my network cable, my broadband router still registers that it's not connected. I've tried resetting the router, reinstalling both the broadband and the atheros wireless card on my laptop(but there doesn't seem to be anything wrong with that...), and, as said, replugging it. I'm kind of at a loss; I'm pretty computer savvy but can't really figure this out. My dad said he's going to rewire it to see if that works, but if it doesn't, does that just mean we need to get a new one?

Please help.

I have had the same problem and spent days scouring Google and trying any suggestion that I could find. Last night I found a post from 2002. It seemed ridiculous but I gave it a shot. PROBLEM SOLVED.

1.) Shut dowm your PC.
2.) Unplug the power cord.
3.) If you have a laptop, remove the battery as well.
4.) Walk away from the problem for at least 30 minutes.
5.) When you return, reconnect battery and power cord.
5.) Start as usual.
6.) If this solves the problem, take 20 minutes and post this to all of those message boards that you didn't find the solution to.

This fix appears to work for any OS/MOBO/NIC.

What causes it? I don't know.

Have a great day! :)

I had the same issue on a Latitude D600 after reinstalling the OS. After many days of frustration I found that the issue is due to a duplex mismatch between the internet router and the 570x controller. The default setting on the controller is set to Auto but for some reason this causes the network cable not to be detected, after changing the setting to a specific speed and duplex like lets say 100 full duplex the cable was detected and the controller started working. If your are having this issue try playing around with the duplex settings on the controller.

how do you play around with the duplex settings on the controller? sorry, i'm not that computer savvy.

Open device manager
-Right-click My Computer and select Properties.
-System Properties window should open, click on the Device Manager button under the Hardware tab.

Device Manager should now be open.
-Find the controller under the Network Adapters.
-Double click the controller to open its properties window.
-click on the Advanced tab (This is where you can change the speed and duplex settings).
-Select Speed & Duplex on the left side of the window (you should see its current setting (Auto)towards the right side of the window on the Value drop-down).
- Click on the drop-down and select a setting other than Auto (Try 100 Mb Full) and then click OK to close the window.

Right after changing this setting the controller should detect the cable righ away. Let me know if this worked for you....

After WEEKS of having my internet connection unavailable after my Win 7/Dell computer woke up from sleep/hibernate, I have used this tweak and it worked!

After hibernate, my internet connection (Ethernet cable plugged into the router/firewall) would be out. I tried the network troubleshooter, and it kept giving me the same cable unplugged. I tried the suggestion to unplug/re-plug, and that didn't work...and was a real pain too. Like most, my cable connections are at the back of all the equipment. Since a full reboot always solved my problem, I knew that there was a setting somewhere that could solve the issue.

I set my network card as described by Alexandro010, and have not had a problem with my internet connection being down for a couple of weeks.

I sincerely hope this helps others too

If you are connected via a router, do the LEDs show that the PC is connected ?
If NO, try to unplug the Router power for 15 seconds and allow it to reset itself, while the PC is connected.

2. Try another Ethernet cable or one in a different location

If you disable windows firewall you still get the constant message network cable unplugged BUT everything works. Anyone know how to keep firewall active and keep the connection working.
