Why won't my mac file share with my network?

I want to share my files throughout my home network, but my mac computer is the only one that is causing trouble. My other windows computers and the USB drive connected to my router is working fine. Whenever I try to look for these devices through the network folder on my mac computer, it just sits there and no other devices appear. On any other computer, they will show up within 5 seconds. I have let it sit for 5 minutes and I nothing has found up.

How can I get these computers and usb drive to show up. This mac has been resisting me the whole way when it comes to network.
