If they sync at 15Megs, how can they download at 15Megs?

How strange .

My sync is 39992kbps. My IP Profile is the maximum possible, 38717kbps.

Why is that strange? Sounds normal to me.

he may well have a sync of 40meg but his throughput is capped due to something at BTs end. 15 meg is guaranteed throughput from openreach over the gea fibre, what the isp set for throughput is another story (12mb does sound rather familiar). Using the BT tester is the best way to find out what is going on.

They can't. You can't download at your sync speed (and I never claimed you could).

oops, missed page 2. Yeah straight on the blower to BT they have f'd something up.

What is strange is that you say it is normal.

using http://www.speedtester.bt.com I get the following:

Max acheivable speed 38717 down and 10000 up.

test shows 32246 down and 7992 up...then I do speedtest.net and get 2300 down and 6009 up

this all sounds OK...BUT why does speedtest.net show poor results and videos are not streaming OK. I have a 'download meter on Firefox and this shows about 800 max ?

I'm not wrong about about the 15Mb minimum speed as it's quoted all over the internet and was repeated by BT to me today when they installed mine.

You appear to be mixing up min sync speeds, with "Assured Rates", something that i notice a few ISPs reps are doing also

The Assured Rate is 12Mbps

You said

They say: "customers can expect a minimum download speed of 15Mb on its new Infinity packages.". The difference between sync and throughput on the BT speed tester is minimal (a few percent) and would not account for this chap's problem. By "guarantee" I did not mean that they will work to make your line achieve this speed, I just meant that they will not leave you with a BT Infinity connection if they do not get 15Mb minimum sync on their tester
