Engineer. I gave it two months on the Billion with negligible error rates. We have seen other people with it automatically removed at that sort of time, and even IIRC one at about three months, but in my case it was quite ridiculous from the stats. I got fed up and hit lucky with getting it reset.
I tried several different modems during the banding, which started out of the blue while all I had was HG612s. On a Huawei cabinet I don't recommend the ZyXel VM1312-10A or the Draytek Vigor 130. But while on banding, with G.INP and the typical very low interleaving level, both of them and this Billion were reporting around 67Mbps Attainable where both HG612s only reported in the high 57Mbps region.
At the point I installed the Billion my banding was at 45Mbps but jumped back up to 55Mbps after three days. Before I started messing with the other kit, primarily trying to get dual band IPv6/IPv4 working but also wondering if modem hardware and firmware had advanced since the HG612 with SP08 was frozen, it had been at 60,000Kbps.
The removal of banding brought back immediate interleaving of 1099/1 and sync of well over 59Mbps and Attainable above 67,500Kbps. Three days later, surprisingly during the day rather than overnight, G.INP kicked back in as expected with the syncs in my sig and attainable varying between a fraction below actual and about 900Kbps above. I'm going to leave well alone now!!!
HappyBunny on MyDSLWebStats. I don't have it monitoring 24/7 but it was on occasionally on for a few days before last night, with a 24 hour spell till early this morning, and back on just before 8am.
An interesting fact I found on banding was that the IP Profile was always well below the expected 0.9669 of sync. (0.9679 on standard interleaving). I discovered that I could access the last few days of the AAISP Radius log on my AA control panel, and on re-syncs the speed BT Wholesale were reporting to them was variable as expected, and was the figure being used for the IP Profile. But all the modems were reporting a sync of exactly the banding figure or 1Kbps below it. I could see the banding figures on another AAISP log.
Hope that is useful. I believe the HG612 should now be consigned to history, or perhaps retained for fallback should its better replacement develop a fault.
Kindness isn't going to cure the world of all its awfulness but it's a good place to begin. Daisy Ridley.
