Thanks for that Ronski. I have started to look into this although I seem to have my 66u running ipv6 no problems on a fork of merlin all thanks to @Skyeci.
These are the stats I am seeing now after all the wiring redone from the inside and the master back to it's original location. Do you think I'll keep my interleaving turned off
?
Just thought I'd let you guys know, the only issue that remained with qube was the hole in the wall and they have offered £75 pound bank transfer for me to get that sorted as they have no one who can work on brickwork.
Thanks for all the help and info guys, looking like it is all sorted now.
