The person who provided this information may not have known that the broadcast power of wireless routers is limited by law, so they all tend to behave pretty much the same in installations.
If you are saying that the AirPort Extreme is behaving about the same as your previous wireless router, that would be expected.
You will likely need to add another AirPort device in the bedroom and connect it back to the AirPort Extreme using a wired Ethernet cable.
