... Now here is why most of you are having wifi issues with the Roku 2 models.
(1) Roku 2 is 2.4 ghz only, but quess what ???? They have capped the wifi speed to a max of 65mbs. That's right 65mbs. No matter what your router can provide the new Roku's will only connect at a max of 65mbs.
No, that is not why people are having problems with WiFi on Roku2. They are having the problem because in Roku2 the antennas are just etched on the circuit boards instead of being separately mounted as in Roku1. There was topic about that by a person who knows what they are talking about here a while ago.
You on the other hand make me gasp in disbelief with your rant of 65mbps being a problem, because video streaming is done at MUCH lower rates - most all streams are under 1.5 Mbps - and if you want details, when you see video playing, count the dots when Roku is buffering, it goes like this:
1 dot = 0.5 Mbps
2 dots = 0.8 Mbps
3 dots = 1.1 Mbps
4 dost > 1.1 Mbps
I don't even think Roku can play anything above 8 Mbps or is it even allowed by H.264. For such low speeds you don't need 802.11n - heck, you don't need even "g" - you can live with 802.11b, the oldest widely deployed WiFi! The 11Mbps of "b" will be able to deliver all kinds of internet streaming and more often than not the bottleneck will be your connection to the ISP.
PS. 65 Mbps is almost the maximum (72mbps) 802.11n can deliver over single 20MHz channel and IT IS FORTY TIMES MORE THAN NEEDED, so stop complaining. To get over that you have to be on 40MHz wide channel but Roku will see no benefit either way, the "pipe" it has already delivers 40x more than it can consume
