How to check if your own network port is working (NIC)
If you have ever wanted to check your own NIC (Network Interface Card) to see if it working than you have come to the right place!
Checking Your NIC Steps (CMD) – Windows
I only use and have a Windows machine so we will be using Command Prompt. So hit the key on your Keyboard located on the bottom left hand side that has the Windows logo on it.
Afterwards type CMD into the search, and hit enter to open Command Prompt.
The first command you can type is:
If you have ever dealt with networking or running your own website I’m sure your already aware of the term localhost.
If you get a response at all than your computer’s network port is working.
If your still having trouble connecting to the internet, your router, or any other device via an Ethernet cord than you should troubleshoot those devices, and cables since you have just determined that your NIC (Network Interface Card) on your current device is in fact working.
If you DO NOT get a response using one or both of the above commands than the Network Interface Card on your machine is BAD. If you just got your computer, and it is custom built by yourself than you should double check that you have installed all the necessary drivers. Windows Update in fact is NOT a fix all solution for hardware and does not have drivers for everything.
If you simply don’t have a CD drive to put the driver CD that came with your computer or motherboard than usually you can get the drivers online from the manufacturer’s website.
In a later post I’ll go over the use of Wireshark to help further troubleshoot an entire network to help track down and identify network issues.
