The network controller you're seeing is for the Ethernet adapter. If you're not using an Ethernet network connection (a wired connection), you don't have to worry about it.
What is a Network Controller in Devices?

I could not connect wirelessly. I went into Device Manager and it showed a yellow exclamation mark on Network Controller. I went on a wild goose chase trying to find out how to fix and could never got an answer. This will give you a laugh. I had been moving my computers around. When I moved this one I looked at the back to see if it had a wireless adapter attached and it did. Wait, no it didn't. It was for the wireless mouse! Why can't they color those a little different so this doesn't happen?) So then I installed my wireless adapter and wow internet. The thing is there is still a yellow exclamation mark on my Network Controller. Am I going to run into trouble later on down the road?
