I have experience 3 or 4 periods where the download speed of my connection drops below 2Mbps intermittently. This is first evident when phone apps and/or browser sessions start to report loss of connection but the hub remains lit in blue. These periods have occured since we moved into the house in March 2017 and there have been about 6 of them with long and tedious phone calls to BT of the last two occaisions with me spending over an hour the first time and well over two hours the second with a total of 4 calls in all (and a couple of call backs not made). I have unplugged the socket front, moved the hub to the main socket, installed an ethernet connection to my main PC from the hub, upgraded my hub, run silent line checks, disconnected all my wireless devices and finally purchases a 4G hub so I can remain in the modern world whenever BT (or Openreach) are unable to provide a reliable service.
Another period has started yesterday - first noticed at about 17.00. At 18.40 BT Wholesale reported 2.0 Mbps and at 18.44 1.85 Mbps. I believe we are 1.2km from the exchange and can only expect 8Mbps max.
The tech log from the hub is included below in case that helps at all.
So can anyone help me get to the bottom of this please?

from your attenuation I think you are nearer 3.5km for exchange and max is about 8mb
your stats look ok with 3+ days connection time and if you could maintain a stable connection and get noise margin down to 6db then your speed would move closer to attainable
id the download speed problems when you use wireless connection? is it ok on ethernet?
run btspeedtester and when first test completes run diagnostic test and post results must be done with ethernet conenction not wireless
Thanks for the reply.
Here are the results over ethernet but they are not relevant because the service is running OK at the this moment. I can tolerate the variations in speed between 4Mbps and over 6 Mbps, my concern is the repeated drops to 2Mbps and below when it becomes impossible to even answer an email.
1. Best Effort Test: -provides background information.
|0 Mbps||7.15 Mbps|
Max Achievable Speed
| Download speedachieved during the test was - 6.57 Mbps|
For your connection, the acceptable range of speeds is 2 Mbps-7.15 Mbps.
IP Profile for your line is - 5.88 Mbps
2. Upstream Test: -provides background information.
|0 Mbps||0.83 Mbps|
Max Achievable Speed
|Upload speed achieved during the test was - 0.61Mbps|
Upstream Rate IP profile on your line is - 0.83 Mbps
We were unable to identify any performance problem with your service at this time.
It is possible that any problem you are currently, or had previously experienced may have been caused by traffic congestion on the Internet or by the server you were accessing responding slowly.
If you continue to encounter a problem with a specific server, please contact the administrator of that server in the first instance.
Please visit the FAQ if you are unable to understand the test results.
btspeedtester still having problems - as you can see your download speed exceeds your profile which is wrong
can you try speedtest.net and post results please

Were those tests done with a wired connection? If so, then the slower tests may have been run when the line was experiencing errors, which is probably why the target downstream SNRM is 9 dB.
the important infrmation missing from list is connection speed and ip profile
