Thanks, but I unlocked both my HG612s very early on, and upgraded to the unlocked 30SP08 firmware when that came along. G.INP has been active on the line for a very long time as well, effectively removing the interleaving it had.
I do reasonably well know what I'm doing

. Though none of us can know 100% and I am a long way below WWWombat's level. The solution to my banding, lies in:
- waiting even longer, or
- seeing if AAISP can get a DLM reset done, which is unlikely seeing as their own and the GEA test they have run show no fault. Which is not surprising as there is no fault and never has been as far as I know. Just something happened way back, perhaps a violent couple of thunderstorms or the like, or
- seeing if they can trigger it by an Openreach product downgrade and then upgrade, as other sources tell me that resets DLM if associated with a migration away from WBC. I don't know if it does if staying on WBC which with AAISP I probably would. Or
- pass off this mortal coil and not have to be irritated by it any more. That's possibly what Openreach and BTW prefer users to do.
But as I said earlier - this isn't my thread and every time someone posts to me I have to reply. Which continues the unintended hijack. I shall get it sorted, or not. But none of the standard suggestions will help.
