I still don't think it makes any sense for BT to disable G.INP on all ECI lines because of what must be a comparatively very small number of FritzBox and Draytek devices. I think the vast majority of all end users will be using ISP supplied devices, plus I would have thought that the people who would buy a relatively expensive high-end device like a FritzBox or Draytek might also have a "free" ISP supplied device for testing or fault diagnostic purposes.
Or would they instead get offended at the suggestion that their £200+ device might be at fault?
I agree. I wouldnt be surprised if there is some other (possibly ISP) modem somewhere.
The Draytek case I linked to above, had no problems when using the PN supplied router - just the Draytek.
I also asked Simon who had problems with his Fritz!box disconnecting if he saw the same issue with another modem, but didnt get a reply.
None of the 3 cases on TBB mentioned they'd tried other modems either.
I dont monitor the ISP forums, but Ive not seen any of the issues reported on an ECI modem anywhere.
I've seen one 'possible' HH5A on Plusnet (therefore may not have updated f/w?).
Ive just checked out the Sky forums - admittedly Ive only checked the first page.. but it will be something like
this that we are looking for - note how it suddenly started after 17th of March which is when rollout started.. then note someone else says 'me too'. Details are scarce, but what if it's say one of the older Sky hubs... may be another older ISP modem such as TT... who knows?
