It seems that CyberGhost, a free VPN service with German IP address, may sometimes throw “A network cable is unplugged” error after installation. This post presents several suggestions to fix this error.

One of the readers of this blog, Tran, has complained that he was could to run CyberGhost VPN:
After reading your article, I tried to install CyberGhost. The installation process is smooth. After completing to install the software, I restarted the computer. But there was a problem: when I double clicked CyberGhost VPN network icon in MY NETWORK PLACE to connect, a noticed “A NETWORK CABLE IS UNPLUGGED” error, while my PC still connected to the internet.
I was not able to reproduce the error, but I found a comment on warezscene.org from Jetman that offers several possible solutions. I reproduce below Jetman’s comment.
Question: Fixing Network Cable Unplugged Errors in Windows
Answer: Several possible causes of “A Network Cable Is Unplugged” messages exist. The error message appears on a computer when an installed Ethernet adapter is seeking to make a network connection.
Try the following tips to resolve your problem:
- Disable the Ethernet network adapter if you are not using it. This applies, for example, when running a WiFi home network with computers that have built-in Ethernet adapters. To disable the adapter, double-click the small Network Cable Unplugged error window and choose the Disable option.
- Check both ends of the Ethernet cable connected to the adapter to ensure they are not loose.
- Replace the Ethernet cable with a different one to verify the cable is not damaged.
- Update the network adapter driver software from the manufacturer’s Web site.
- Change the Link Speed and Duplex settings (using Device Manager) to use “100 Mbps Full Duplex” or “10 Mbps Full Duplex” instead of Auto Detect.
- Replace the Ethernet network adapter if it is a removable PCI or PCMCIA card. First remove and re-insert the existing adapter hardware to verify the card is connected properly. If necessary, also replace it with a different card.
- The device your Ethernet adapter is connected to, such as a broadband modem or network router may be malfunctioning. Troubleshoot these devices as needed.
The support forum for Cyberghost, although in German, and thankfully I am of German descent, roughly translated they are saying to make sure your DHCP client is running and that there are known issues with Windows XP firewall settings.

don’t you think cyberghost has much less speed than ultravpn (https://www.ultravpn.fr)
among all the vpns you talk about I think ultravpn is by far the fastest
I will write a blog not to use CyberGhost VPN because it is owned by the pesky company in hiding IP.
