The bracket should come with the router. It's a plain piece of plastic, probably worth less than a quarter. Of course it works as it's supposed to - it should fit into the mounting slots on the router and it fits. And it's small enough to fit in a small USPS envelope. If you want to hang the router, you need a bracket.
