Remove unused LAN connections

So I've set up my desktop PC to function as a portable WiFi hotspot for my other mobile devices.
First I used the Cmd Prompt to create a sharing network, but since I had to open that every time I started up the computer, I switched to using a program called MyPublicWiFi (1 click setup).

However, in the last few days, my WiFi connection was getting kind of buggy. (No internet connection with my phone while I was connected to the WiFi network, etc)

Just now, I looked at the Network Connections, and there are 3 LAN connections that weren't there before. (picture: http://i.imgur.com/WErP6m2.png)
Are they part of the problem, and how do I remove those networks?

I hope you can help!

You would need to open Device Manager and find them under Networks, then remove them that way. Most times it is third partuy software that causes this.

While they are sitting there, they are doing no harm.
