Thanks Darren,
What Bill makes sense, your test results are displaying over 67mbit but the fastest speeds i'm seeing are around 25mbit, this ties in with the download speeds of 1.8 - 2.2mb, this speed felt like the connection was at the limit, I certainly wasn't seeing speeds representative of a 67mbit connection - so it seems I'm missing out on around 40mbit somewhere along the line?!?
Hope this helps.
James
