Hmm, on my book fancy produces the page number in the footer of new
chapter pages, and the header on all other pages. So at least for
Standard Class (Book), it's behaving as designed.

Sometimes changing Document Class isn't enough, or is a bad move[1].
Sometimes you need to use a layout file to develop your own Document
Class, based on an existing one (I always base mine on LyX Standard
Class (Book) because less unpleasant surprises).

I wrote an article about making your headers and footers do *whatever*
you want. If you want page numbers at the bottom, you can do so with
your layout file. Here's the article:

Before going to all that trouble, make sure there's not a CTAN package
(not a document class, just a package) you can download to put the page
numbers on the bottom without further side effects. There are three
times more CTAN packages than stars in the universe, so it's likely
such a thing exists, *if* you can find it. But if you can't find it,
don't despair; you can always strongarm it as shown in the preceding
link.

Anything's possible, but that shouldn't matter.

You might or might not need to tweak your layout file to *prevent* the
page numbers from printing at the bottom of your \frontmatter pages
after making the changes.

[1] Much too often, people recommend changing your document class to
    achieve one feature. Invariably, that new class lacks some needed
    features of the first one. I'm not sure if it's Koma or Memoir, but
    one of them clashes with \hyperref, requiring all sorts of hoop
    jumping. In my opinion, the document class should be chosen based
    on the overall look you want to achieve, and then tweak the rest of
    the features you absolutely need "your way". Also, if you intend to
    write multiple books, I'd suggest choosing one and becoming an
    expert at it.
