thanks BK I'll give it a shot as this is going nowhere, then after Christmas and New Year I will start looking to buy a Draytek or whatever is recommended that works with PON via WAN ports
well i phoned BT:
firstly, BT's website when opting out (14th November i opted out) - said "this takes just a few days to turn off"
when I called weeks later:
rep 1: I dont know I'll ask, 7 days
rep 2: I've never heard of a hotspot?
rep 3: don't know I'll ask, 28 days
rep 4: 28 days
rep 5: 31 days (because it had now been 29 days lol)
rep 6: disable your wifi - (it is still there while all your wi-fi is not broadcasting, and I need my wifi)
It has been 32 days since I "opted out" - others on BT forums have said it has remained for them too after "opting out" months ago - so I'm not alone here, there is obviously an issue with BT's systems somewhere, OR, they just point blank refuse to turn them off.
So its looking like a new router route after new year.
