Map a network drive?

Edit: I finally figured it out, but I do have a follow-up question. My computer is connected to the router with ethernet, and the QNAP is connected to the router with ethernet. When I try to transfer files, they are steady at like 11 MB/s. I was expecting it to be faster. Is this what I should expect for speeds? Or is it (for some reason) transferring the files via the internet instead of straight tot he QNAP from my computer? Or something else entirely?

***Paragraph below is old, and solved, so skip over it.

Hi, I am a bit of a noob here. I had a drobo (old one) that seems to be crapping out lately, so I bought a QNAP TS-251+. With the drobo, I just ran some software and it mapped it as a network drive for me. The browser thing is neat and all, but I just want a network drive mounted on my computer and every other computer in the house that is just simple and in windows explorer. For the life of me, I can't figure out how to do that, though. I managed to log in to my QNAP from a browser (don't ask me how) and I'm just kind of lost. When I read through this subreddit, it's like reading another language. Is there a way for me to just have my QNAP show up in windows explorer/This PC/My Computer so I can access files that way?
