[quotemsg=16724534,0,764133]Mmm...ok, that does make sense.
Maybe the issue is, the Miracast hardware in your Roku, or in your TV, is 2.4 GHz and 802n only. The dual-band, 802ac adapters might be slow to do it to avoid additional cost/complexity until there's more demand to do it, and it has to increase driver size/complexity. PCs have less need for it...not no need, but less need. Android has strong reason to do it to overcome the small screen size.[/quotemsg]
no problem, the wifi alliance site had some good info on compatible parts but no specific dongles. instead it seems to give the actual chip model number from broadcom and other oem's. i can look and see if this is listed on the spec sheet for the actual dongles to find something. there seems to be a good number of chips compatible, i only need to find what dingle has these chips in it
or maybe i'll just wait until next year when the masses figures out how neat the feature is and they begin actually advertising it on the boxes.
what does suck is that apple does not support this so far as i can find. my main phone is an iphone but my secondary one is the android lg volt. kills me that my $40 phone does something my $700 one won't do

i bet the wifi chip can do it but so far i can;t find a way to enable it. was hoping the jailbreaking crowd would do this but again so far this is a new thing and no one is working with it much yet.
