The WiFi icon is used for wireless connections, but either way, when there's a network issue, you see the icon is presented here.
The red X means the network isn't up. Now in this case, I've unplugged the network cable, so it's an easy fix. There. Similarly a yellow triangle may indicate that the network seems okay but the internet connection is down.

Generally speaking, the most common fix windows can do is to reset the network interface card or NIC. For network connections, this is the best you can do on your computer.

Other useful items present themselves on this screen. In fact, the last item on the list, one of them, is network reset. This is where the troubleshooter most often leads you, as I mentioned earlier.
