    Well, I've read of at least one using the W-CCK as a wireless bridge/adapter for a DIRECTV HD-DVR to connect to his router then to another HD-DVR connected by ethernet to the router for WH without issues.

    So if it is indeed only 54 mbps (likely even much less than this for true throughput) would that still be sufficient for WH service like that, even for HD programs?

    I'm thinking maybe a mistake in the specs...

    I'm not sure I'm following this... They have a wireless CCK to connect one DVR to their router and then they have an Ethernet cable from the CCK to another DVR? Or is the second DVR just connected straight back via Ethernet to the router? If the former, that wouldn't make sense as the two receivers can perform MRV via the DECA cloud. If the latter, just adding a DECA to the second DVR would be an easier and less troublesome setup.

    In any case, with regard to a connection of 54Mb/s for MRV, I was able to stream SD content to and from a DVR that way before I had a DECA setup. Every now and then, I would have some issues, but mostly it was pretty smooth. I don't think I would have been that lucky streaming HD content though.

    An HD stream from one DVR to another is only about 6Mbps, on average. You could handle at least 1 or 2 streams across a standard G link, as long as the link was stable. Problems in whole home distribution come from instability much more than throughput limitations.

    Sure, if he has a SWM setup. But if he has an older multiswitch and no ethernet at the remote DVR's location, this works (granted, in an unsupported mode). As long as you can get a STEADY 10Mbps, HD streaming should work.

    Think this may have already been addressed, "but":
    I've been able to stream OTA HD @ 16+ Mb/s through my WCCK to computer for DirecTV2PC.
    I've been able to support two C31s through two WiFi hops, but it showed it wasn't perfect, while the same was fine with only one WiFi hop.

    So used to SWM now that I completely forgot about using the CCK in a non-SWM environment. Yes, that would work fine in the second scenario I described. The CCK is just being used like a wireless adapter and is similar to how I ran MRV before being on SWM/DECA.

    Just so everyone is clear, the throughout rating for wireless is in both directions, meaning that it is only half that in either direction. Therefore, for wireless G (rated at 54 Mb/s), the max throughput is actually only 27 Mb/s in either direction. Knock off 10-20% in overhead and you get down to around 20 Mb/s.

    As far as the wireless CCK, I doubt that it is really rated at 54 Mb/s. Wireless N is 150 or more.
