Thanks. I'm on day 15 now, so like the OP, just waiting. I have no problems with TalkTalk service.
For what it's worth I think I lost G.INP when I migrated ISPs. I don't have an unlocked modem but speed tests suggest my current sync speed is about where it was before I got G.INP (59Mb/s). I've been with my current ISP for two months now.
They are actually in the process of changing backhaul providers for me so perhaps that will have an impact.
I'm a bit sceptical because I'd have thought a simple ISP migration would have zero impact on my sync but something changed. I went from 68Mb/s to 59Mb/s overnight. Could of course be crosstalk but that seems a bit of an unlikely coincidence.
