It is not your download speed its your upload speed that causes the problem

Actually it's not upload speed because the same connection works fine for both of us if we don't use Sony Z3 compact. and I've actually had this problem with Sony Z1. Please investigate and give us a proper solution. This happens even if we use Headphones! I mean what the!! Please any help would be appreciated
