Router for 200/200mbit fiber home

[Titan243]

Hi

I bought the EnGenius ESR9850, thinking that it could manage about 600mbit, according to this sites tests. It's topping off at 140mbit down, while I'm getting 220 when I go directly from the wall-socket.
Am I misunderstanding something here? If so, I'd very much like you to recommend me a budget router that can manage at least these speeds through NAT

Thanks
