Auto.Renamed like Local Area connection#2

yuvasri · 06-07-2009, 07:48 AM

I give the IP Address it showing error message that "The IP address 192.168.1.143 you have entered for this network adapter is already assigned to another adapter 'Atheros L2 Fast Ethernet 10/100 Base-T Controller'. 'Atheros L2 Fast Ethernet 10/100 Base-T controller' is hidden from the Network Connections folder because it is not physically in the computer. If the same address is assigned to both adapters and they both become active, only one of them will use this address. This may result in incorrect system configuration". I can't solve this problem directly, so i reinstall the OS it will work only 3 or 4 days after that i'm getting same problem. How can i solve this problem. I want to replace the NIC card or any other solution is available Please reply immediately.

Repair duplicate IP address on network issue.

Turn off everything on the network, ALL the machines and any other network device like network printers and NAS drives.
Turn off the router and modem.
Turn on the modem, wait for a steady data light.
Turn on the router, wait two minutes.
Turn on the network devices and computers, one at a time.

This issue is usually caused by resetting a router without resetting all the network connected devices.

Another issue that will cause duplicate IP addresses is assigning static IP addresses to devices that conflict with the router's DHCP address range. If you require static IP addressed devices on the network, they should be configured to be in the same subnet but outside the address range defined for the DHCP server.

That is weird, you could setup an address manually.

The adapter with the zero MAC address probably has a driver problem.
