I am looking for a draytek N Wireless Router (pref Dual Band) which supports "simultaneous" use of a USB Printer (Dell All in One 962) and a NAS (2TB LaCie Network Space 2 with Ethernet and Hi-Speed USB)

I would like to connect the NAS to the ethernet port and the printer to the USB port of the router.

Any sugestions?

The 2130n can do that, it's got 2x USB ports and pretty good throughput on the NAS side, although you can also do that with any of the other routers that support USB storage because you can plug a USB hub in to the router.
You'll get better throughput with your NAS using the ethernet interface though, I think, having looked at the specs for that drive.

Thanks Voodle,
Let me have a look at the foll. comparison chart as well.
