Win 7 internett problem

[prosim91]

Hello I have problem. So I have win7 and my internet dosen't connect with pc but before was yellow triangl on internet icon but now there are just red x. what should I do? Does it make sence? what icon is better is it yellow triangl or red x? and how I get yellow triangl back to internet icon. Before I just restart my pc and then yellow triangl was gone and then comes red x

this yellow triangle means you dont have the driver for the network card on the system and the red x means you dont have internet connection at all so check your motherboard maker with the os you use to get the driver .
