Downstream sync speed query

[jonesypeter]

We have BT 'Superfast Fibre 1 Unlimited' and I have recently had some queries over speed.  I had a first line engineer out (who fitted a new panel on the main socket which improved things), but I'm still rather confused.

We are using the standard BT Smart Hub and the downstream sync speed is showing as 32.2 Mbps.  First question. How does this relate to the actual speed you should expect on a client connected directly to the router via Ethernet?

When I run the BT Wholesale speed test with Wireless turned off on the router and only the PC I'm typing on connected I get between 25Mbps and 27Mpbs. I'm trying at different times and when I run it now I'm only getting 25.93Mbps.

My minimum speed promise is 27Mbps and I keep on being told because the router is showing 32.2Mbps that things are fine.

After the engineer visited I did get a call from a nice chap who offered to send me a free Smart Hub 2, which I have done some initial testing on and the speed does not improve.

Any suggestions?

Thanks

Peter

Your download speed will never be as high as your sync speed due to protocol overheads. However, it should be very slightly higher than it is which is possibly due to errors on the line. Is there any noise when you carry out a quiet line test on 17070 from the test socket behind the removable faceplate of the master socket.

getting 26mb download speed on 28mb profile looks good to me

Thanks for the suggestion and no sounds that I could hear. Does anyone from BT monitor these forums or is it just community?

The minimum speed promise refers to sync speed not download speed, no ISP guarantees throughput speed.

post hub stats from advanced settings then technical log information

[jonesypeter]

OK, will post later. Thank you.

from your stats you actual speed is almost at attainable and with noise margin down at 3.3db G.INP is activated boosting speed so you are not going to get any faster. your profile at 28mb is correct for your connection speed and download speed of 26mb good for that profile

OK, I have saved screenshots and shared them via my Google Drive account. I can share them any other way if preferred. Will post logs later. https://drive.google.com/drive/folders/1gt_Z6-bCmQgGeVWdyv5cvxeXioo6gdA_?usp=sharing

can you just post the hub stats on forum saves changing screens and easier to read using google drive means I need to download which I will not do
