So because btw tester does in fact use multi thread the matter has to get much worse before they actually class anything like what we are seeing as a problem.
Beyond funny this.
I wonder what the chap at Zen will tell me tomorrow.
Last one I have spoken to suggested using LAN for streaming rather than wifi (ps3)..
What else can I say 
Unfortunately yes on that, and that could well be why the BTW speed-tester uses multi threaded ,it also will allow the speed to ramp up before it actually starts measuring throughput too,
And yes mention wireless to any ISP they will always point the finger at that, (because quite a lot of customer complaints about speed and buffering ect are actually caused by wireless ) or it's down to how it has been set up by the EU Some aren't very knowledgeable
Just keep testing your throughput and if it seems lower at any point run a bt speedtest and compare ,It took me a while before i was able to provide a TAP3 that was under performing below 40mbps your IP profile from that BT tester tells you what they consider to be the acceptable range for your line, if it falls below this, you get the TAP3
