Dual Band USB NIC recommendation?

[cohomology]

Just found out that the carppy airlink usb nic is the real bottleneck for my whole network setup. What will be the best dual band usb NIC on the market? BTW, I just upgraded to the RT-N66U, and really want to take full advantage of the powerhouse!

TIA!

The Linksys dual band uses broadcom 2 stream radio, would assume it to be the best match to your router.
