OK so just for good measure I've:

Rebooted the HH3 and Openreach modem (is a newer ECI modem, installed this year)
Disconnected all and sundry from the router, disabled the router WiFi
Connected to my laptop via Ethernet
Disabled AV / Firewall / Etc (use Comodo free internet security suite usually)
Disabled Wifi card on laptop
Ran CCleaner
IPConfig /release
IPConfig /renew
IPConfig /flushdns
Closed any tray apps

Unfortunately this hasn't made any difference:

So definately a BT issue. Hopefully it clears up during the stabilization period

Can you get a screen shot showing Task manager during the downloads? It should show the speeds being seen every 1/4 second or so. That will show whether the maximum of 70+ is being reached or something is throttling the traffic at a lower level.

I had task manager open throughout the tests but because the laptop was connecting to the router at 1GBps the paltry throughput I was getting was barely registering. I.e. a couple of pixels barely registering

In reply to a post by izools:

Weird thing is BT Speedtester reports an IP Profile of 77.43 Mbit/sec. So my sync rate must be around the full 80 meg mark to be given an IP profile of 77.43 surely?

Yes. IP Profile is approximately 96.79% of sync. 77.43/0.9679 = 77998 79998.

Have you set the Task Manager Option to Auto Scale - ON ?

I too have a 1Gbps network but the scale is at 5% when downloading on a 40Mbps connection and the trace get to about 3/4 of the maximum.

OK, done one.

The first bit of traffic on the graph is the speedtest which seems to tie up accurately with the reported throughput. There is a brief flatline followed by the traffic generated by my copying a 700MB file from my local hard drive to the hard drive of another computer on the network.

I have done this to demonstrate that the wireless conneciton is not limiting throughput - I am able to obtain 11MByte/sec+ (Yes, MB) over my Wireless connection when copying to a wired client on the network.

I am using a 5.0GHz Netgear Wireless Access Point - the 2.4GHz band causes serious bandwidth issues with rates as high as we're dealing with here as you all know. Seems to work well, eh?

That suggests you are peaking at 120Mbps across the wireless ... so your local network is not slowing things down.

Have you checked that the MTU setting are correct? VDSL/Infinity requires 1492 or less.

VDSL2.

Is that just because its PPPoE rather than A ?

Strange that it's showing you're only on 10mbps for your upstream profile. My line sync's at 16993 right now (banded profile [censored]) but upstream IP profile is listed at 20mbps.

Something's weird/stuck/not right
