The NIC is defective... As far as Windows is concerned there is no NIC so the driver will not install. Motherboard replacement is a bit extreme for just a broken NIC. Its possible to get a USB to Ethernet cable: [URL]
HI, I'm using Inspiron n4010. Recently my hard drive failed, I replaced it with another one and since then I'm unable to connect to the internet with my cable, though my wifi is working well. Also when I tried to install the network drivers it said installer can't find Ethernet controller on your system. Kindly help. Thanks in advance.
