Thread: LAN card Problem

I have been having a problem since for the last two months. I use SIFY broadband on my home PC, and when the IP address is entered into the LAN card, a message appears "Your IP address already exits" (the IP address "is provided by SIFY). The service provider's solution to this was to format the PC. My friend advised me to go into safe mode and uninstall all LAN card drivers. I tried, but my Realtek LAN driver and others did not uninstall (my PC now has only a LAN card). When uninstalling and installing, new local area network connections (Local Area Network 3,
4, 5) are created. Can this be solved without a fresh Windows installation?

The problem is that your LAN card is listed as an unused or disabled device in the Device Manager. You will have to delete the older LAN card from there, as it is using the IP address this is now allocated to another LAN card. To resolve this, open a Command Prompt window and type 'set devmgr_ show_nonpresent_devices=1' and press [Enter]. Then start the Device Manager or run the command 'devmgmtmsc' from Start I Run. Now, click on 'View' and select 'Show hidden devices'. Delete all LAN cards listed here (uninstall them) and then reinstall your LAN card drivers.
