Hi
I would second that. Whilst the SoC chip may support G.Fast, there are other components external to the chip in the analogue stages that will need to be different to support the higher frequencies, then issues with licensing, testing and patents come into play that will mean they will not add support for G.Fast unless the product is going to be advertised and sold with it, which doesn't seem to be the case.
Netgear will simply bring out a new router with support for G.Fast when the time is right to cash in, they seem to be bringing out new routers every few months, and the D7000 isn't that different to the D6400, yes Netgear like to advertise a faster CPU in this model, but no one has been struggling or seen lower throughput's on the D6400 or the dozens of other routers running the same lower speed chipset, the higher number most people will see is on their electricity bill! The speeds that Wi-Fi equipment are boasting these days (and has always been) is marketing, those top speeds can't be achieved outside the test lab and there is hardly any, if any, devices that support the trick they use on 2.4GHz to boost the claimed speeds that are then aggregated to 5GHz to come up with these huge numbers.
