Why is world of warcraft taking so long to install?

I just got a brand new dell inspirion laptop so I decided to play world of warcraft again. I’ve been downloading to the game client off of the website for almost 14 hours now and its still at 8 percent. What is wrong? My friends have also recently downloaded world of warcraft and it only took them 2 hours. Like really, I haven’t even hit the patches yet this is just the game. Can someone please tell me a way to make this game install faster?
