    Why in the world didn’t TiVo use 802.11ac wi-fi in Roamio? I am updating all of my Apple toys to the new standard. I asked TiVo chat and they were ho-hum, 802.11n works fine. So does my 1964 Pontiac.

    The CPU probably doesn't have that much transfer bandwidth (just as the Premiere is limited to roughly 80mbps), so it wouldn't get used to its full potential. But it will be interesting to see what kind of speed we can get out of a Roamio.

    most likely because 802.11ac is not a finalized standard yet.

    These responses are pretty weak, guys. Lack of CPU power and draft spec status? Broadcom announced its 802.11ac chips in Jan 2012, so there was plenty of time to plan for supporting it, including any CPU, RAM or other architectural needs. While the standard hasn't been completely finalized, it's at the final stages and isn't expected to change much at this point, which is why there are many routers and devices already on the market that support it.

    What does 802.11ac provide that you think a TiVo needs?

    TiVo hardware has never really been accused of being cutting edge. 802.11ac is just barely starting to hit the market, very, very few people are using it. It's still very much bleeding edge technology and only companies that make bleeding edge hardware are using it.

    That being said if you really want to use 802.11ac you can always use an Ethernet bridge.

    So is 802.11n fast enough to stream shows Tivo to Tivo?

    I'd like to get the base Roamio for upstairs, adding a big (8-bay) antenna in the attic, and use it as my everyday OTA recorder.

    Then stream shows to my (original model) Premiere downstairs (already connected via ethernet to the wireless router), possibly adding digital cable later.

    I'd rather stream than copy because ATSC MPEG-2 generates huge files.

    It should be able to handle 1 stream OK as long as you don't have a bunch of other traffic on your wifi network and you have a good signal.

    Thanks, ordered it & got a free Stream via code:GROUPER.

    802.11n is plenty fast for anything TiVo needs to do, including room to room streaming. The problem with Wireless in general (And why TiVo doesn't allow MRS over WiFi) is that 2.4GHz is an extremely congested band. Moving to 802.11n over 5GHz would alleviate that issue somewhat and the way 802.11ac alleviates that issue further is by restricting it to ONLY work on 5GHz and increasing the number of channels that are bonded together to make it work.

    There is no discovery that led to the design of 802.11ac, they switched modulations, required MORE spectrum and restricted it to 5GHz only. Not exactly rocket science.

    The upshot is that the new Roamio line supports 802.11 a/b/g/n on BOTH the 2.4GHz AND 5GHz bands.

    I used that code and they gave me $50 off. Maybe because I already had a stream in my account.

    802.11n is more than fast enough. You just need to have a properly setup network. Unfortunately most people don't. A properly setup Wi-Fi network has multipls APs and the APs will also not be saturated and will not using congested channels. The vast majority of home networks were not setup to meet that criteria and that is typically why they have issues.

    When I tested my TiVo Premieres and Minis with wireless Bridges, From a user perspective, the experience was identical to when they were connected to Ethernet or MoCA.

    I think you meant that last "b" to be an "n".

    It gives you $50 off the Stream and another $80 off the TiVo, so the Stream is essentially free.

    I thought in order to use stream or mini the TiVo needed a wired Ethernet connection. Am I mistaken?

    And why didn't they give us Quad Core processors, gigs of Ram. 20 tuners Keyboards.... etc....

    Because of cost and at this point adoption is likely less than .5% and noone needs it....

    It's not "supported" meaning they won't support you if you call them, but it works.

    They want the connection between the TiVo DVR and the mini or stream to be hardwired. The reason is that the MPEG2 show travels over that connection and needs both high bandwidth and a clean connection. The connection to the iPad or streaming client can be less robust because the show is transcoded to AVC which requires much less bandwidth.

    On the Roamio Plus or pro the connection between the disk and transcoding chip is all inside the same box, so it just isn't an issue anymore.
