So like many I was affected by the G.INP activations and not being ready for it.
Although I had the correct HG612 Openreach modem, I think it missed the firmware update as my connection was activated very shortly before the activation of G.INP!
I managed to fix my loss of speed and increase in Latency by getting the up to date firmware installed, since I have seen many complaining of having an ECI modem on a Huawei cabinet and not being compatible with G.INP... most have gone ahead a brought compatible hardware and fixed their issues...
Now the concern I have is I've also seen a lot of people talking about they have brought G.INP capable hardware like the HG612 or other Broadcom based hardware for their connections on ECI cabinets, presumably because they think this will be the best way to be ready for G.INP when it's rolled out... But.
Isn't their a chance that ECI cabinets might not be compatible with Broadcom based chipsets... hell at the moment theres bit of speculation that ECI cabs might not even be ready for G.INP... (I doubt this) and if Openreach's comments regarding the matter recently being true regarding the chipset matching the EU's to the DSLAM then are users wasting their money on Broadcom based equipment for something that seems to have had its rollout cancelled/pushed back.
Now I know it has generally been thought that not matching the chipsets didn't matter (BT Retails certainly did) and some even said using certain mix was of benefit to the EU, but as we have now found out there was a reason to use matching chipsets after all.
