For reference/interest: The default CeroWrt numbering is here 
which may help explain how things used to work :-)

I'm currently away on 'holiday' down at my parents house otherwise could 
help/concentrate more.  As an aside, evidently the house is on the end 
of a very long piece of wet string known as a telephone line, actually I 
must be in space judging by the 6 seconds(!) of bufferbloat.  I brought 
an ancient Netgear DGN3500 with me for them (has integrated ADSL modem 
otherwise things get messy cabling wise otherwise it'd be a TP-Link 
Archer C7) running OpenWrt CC r45669 with 'Cake' rammed into it (in a 
slightly more elegant way since we last typed Dave H/T :-)

This has enabled me to relocate back to planet earth and pointed out 
some strange ADSL rate behaviour (which mysteriously fixed itself at 
6am)  Still can't get over the 6 seconds of bufferbloat, latency is now 
under some sort of control down to spikes of 120mS ish - needs more 
fiddling.  No wonder facetime calls were problematic though.
