I know in terms of routers, having a dual band, dual radio router means you can have devices connect at both G and N without dropping the whole network down to G. But what does it mean for wireless playback devices? The top Roku box is listed as "dual band". I assumed this meant it could connect at either N or G, and that the lower models would be G only. That's not the case. They're both listed as G/N compatible. So what does this mean for the top model? It can connect to two different networks at the same time? I don't see the benefit of this. One as a fallback? Or is it pulling data from both connections to make netflix streaming load faster (not sure how this is possible with a finite download speed). Or is it just marketing gobblety gook to make it sound like you're getting a better connection when it's probably the same chip in both? Specs for the Roku XD : 802.11n Wi-Fi (b/g/n compatible) Specs for the Roku XD|S : 802.11n Wi-Fi (b/g/n compatible) Dual-band 802.11n (2.4Ghz and 5Ghz) product specs at Roku I don't have a box yet, otherwise I'd check the networking options in the software. Can anyone shed light on this?
