I switched from TalkTalk ADSL to BT Infinity 1 in January 2017. My postcode is LE9 2EH and according to the BT Broadband Availability Checker, my connection to KIRBY MUXLOE Exchange is served by Cabinet 15.
Cabinet 15 is 285 metres from my home. The copper connection runs underground for 50% of the way. Then, it passes between three telegraph poles, before dipping underground again. Consequently, there will probably be at least five joints in the line.
BT provided a Home Hub 6 router which seems to work OK. My Windows 7 desktop computer has a wired connection to the router. My Windows 7 laptop and several Android devices connect via Wi-Fi.
When I switched from TalkTalk, BT estimated my download speeds would be between 54Mbps and 55Mb, with upload speeds between 9Mbps and 10Mb. I rarely achieved 54Mbps, although I usually achieved the minimum guaranteed speed of 50Mbps.
More recently, BT upgraded their Infinity 1 service to some subscribers at no extra charge. So in September 2017, I noticed a significant increase in download speeds. That lasted for a few weeks and on one occasion, my speeds peaked at 83.13 Mbps (up) and 17.42 Mbps (down). See https://www.thinkbroadband.com/speedtest/15066049535...
Then, performance became erratic but subsequently stabilised at around 56 Mbps / 16 Mbps (tested, using a wired connection to my router).
The BT Broadband Availability Checker quotes the following figures:
VDSL Range A (Clean).
Downstream (Mbps) High 80, Low 65.4. Upstream (Mbps) High 20, Low 19. Downstream Handback Threshold (Mbps) 55.7
VDSL Range B (Impacted)
Downstream (Mbps) High 78.3, Low 51.9. Upstream (Mbps) High 20, Low 15.3. Downstream Handback Threshold (Mbps) 39.8
I have just re-contracted with BT for a further 18 months, in return for worthwhile discounts. BTís confirmation email estimates my download speed will be between 67Mbps and 80Mbps, and my upload speed will be between 19Mbps and 20Mbps. The minimum guaranteed speed I can expect should be 60Mbps.
I cannot achieve the minimum guaranteed speed of 60 Mbps and present average download speeds are usually around 55 Mbps, as per the speed test at https://www.thinkbroadband.com/speedtest/15138528687...

My connection appears to be very stable, and I have suffered no dropouts within the past 12 days. However, I do not understand why the router stats show a data rate of 19.00 Mbps / 60.00 Mbps, if the maximum data rate is 23211 / 77309. Consequently, I wonder whether BT have imposed a cap.
Any advice would be appreciated.
