Using both band simultaneously WD My net N900?

I just got my WD MyNet N900, and I was wondering what kind of usb adapter I would need to get to use both bands simultaneously. I want to use both the 2.4Ghz and 5Ghz at the same time to get double the speed.




The My Net does broadcast through both frequencies at the same time. But I dont think there is a device that will connect to both simultaneously. Lets see what other users can comment on this.
