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.
