Napoleon Total War Steam downloading very slowly

I have an extremely fast internet conection, and when I download other games on Steam I get download rates upwards of 10 MB/s. Just now I downloaded Amnesia: the Dark Descent and it was extremely quick. However, when I try to download N:TW I'm stuck around 50 KB/s, which essentially means it's going to take forever.

Well, it is up to Steam or your ISP or maybe a little of both.

How big was Amnesia's download?

I tried it with Portal and it downloaded with the same 10 MB/s speeds, while Garry's Mod was at the same 50 KB/s. I've also noticed for the slower ones it takes about 10 minutes for the pre-install Steam prep to happen, while with the fast ones the preparation for installation is nearly instant.

Alright for some reason switching from wired internet to wireless fixed it.
