Hi All,
I'm new to all of this.. I got thoroughly disenchanted with my HH5, used both as a VDSL2 model and router. Horrible wireless drops, intermittent routing issues, slow downs etc all with the current .204 release. I was experiencing simultaneous disconnections of all wireless clients, poor throughput and the like. Lync was unusable, and the overall stability of the service over Wi-Fi in particular was atrocious.
In order to prepare and enable myself to use a decent router, I decided to go back to the HG612, unlock it and see what my line performance was like. I used to have a solid 80/20 sync rate, and very good throughput, although it had slipped back to around 72 down / 19.9 up for a while.
I ran the HG612 for about 24 hours to check whether sync speed had improved, but there was no real difference between the HH5 an the HG612 - sync speed down about 72Mb with 6.5Db noise margin.
I upgraded the HG612 to the latest firmware at 11:40, and G.INP seems to have kicked in immediately. My sync speed immediately improved to 80/20 with DS noise margin improved from 6.2 to 8.6Db downstream, and 10.5 to 13.6 Db upstream. FEC errors and bitswaps have dropped to nothing/almost zero at the same time, and interleaving has been reduced a lot, so latency/RTD is now 1ms.. I'm quite impressed with that, to put it mildly!.
A secondary benefit is that the HH5 is now completely stable for wireless and wired clients - no more disconnections so far at all. It leads me to think that Wi-Fi may have been affected by the VDSL modem workload, but who knows.. for now, I'm very happy with my setup.
All stats are up on mydslwebstats.co.uk.. user name is as used here, as well as below. I'd be interested in people's comments on my line stats but it all looks good to me.

I just wanted to thank everyone involved in building the firmware, web tools and expertise to enable this to happen. It's a really fantastic piece of work by the community, and this has saved me so much aggravation and effort in trying to see what was happening and get a resolution. I was resigned to making the best of a bad deal, but for now at least, all is well.
Regards,
Alex
