Hi! First post here.  I'm ready to replace my venerable DI-604 and go wireless. I have a few pre-sales questions about RangeBooster N routers:

1) What exactly does the term RangeBooster mean - how much more range does a RangeBooster router have over a Wireless N router (e.g. DIR-615), and how does D-Link achieve this extra range?

2) Is it correct to say that DIR-625 is a single band router - 2.4 GHz only - while DIR-628 is a dual band router - selectable 2.4 GHz or 5 GHz?

3) What is the difference between the QoS featured in RangeBooster N routers (described as "intelligent QoS") and the QoS featured in the Wireless N routers?

4) Is it correct to say that DIR-628 supports Wi-Fi Protected Setup (WPS) and DIR-625 does not support WPS? I'm asking because I only see WPS described as a feature for DIR-628.

And finally...

5) I have desktop computers. Which is the preferable form of wireless adapter: USB (DWA-140) or plug-in card (DWA-542)?

Many, many thanks for your help.

1) It's a product group name.
2) yes, it's dual band selectable.
3) QoS is configurable, the iQoS is not.
4) I believe thats true.
5) Thats you're preference. I prefer ANYTHING thats not USB.

Thank you. DIR-628 is my choice.
