Hoping someone here can help with the issue I've been having for the past 6 months, though I've seen a lot of posts on this subject.
Long story short:
Moved from Virgin to BT in February 2020, since then I've had nothing but problems maintaining a stable connection. Main problem is the speed of the line slowing down, I have a 50Mb contract, after two weeks I'm down to 25Mb or worse. Log call with BT, Openreach engineer arrives, checks line, all good, boosts speed back up, sure enough 2 weeks later its back down again, I am also suffering multiple disconnections, today I've had 10 in the last 4 hours, usual flashing lights then back to blue.
I'm now having to work from home due to a bereavement and a parent with the early stage of dementia so need my connection to work. Strangely enough I have the exact same package and smart hub in my own flat in London and do not have any of the problems I suffer here in the outskirts of a small city in the east of England.
List of works so far:
1 new socket installed at time of move from VM to BT. Its the only working socket in the house.
2 new faceplates by OR engineers
After much arguing with BT a new Smart Hub 2 was sent and installed to rule out device issues.
Not much connected to the Wi-Fi, 2 laptops and nothing else as BT were accusing my devices of causing the problems.
Line test has come back clear (OR engineers check this first, I've also run my own tests which came back clear, no noise). I've wi-fi sniffed networks near me but there are very few and none using the channels I'm on so no clashes
I've disabled smart setup and enabled and disabled the smart scan function to no avail.
Details from the new hub (I've removed mac addy and wifi name from below) - its been 2 days now since they boosted the speed back up...and its dropped to below 40Mb already..

1st question based on: "Not much connected to the Wi-Fi, 2 laptops and nothing else as BT were accusing my devices of causing the problems."
How are you performing the speed tests? Wireless or Wired? If Wireless then you will be unlikely to get close to the top speed. Wireless is renowned for having speed issues. You could try changing WiFi channels and findint the one with the best speed. Can you (if you haven't) perform a wired speed test?
Tried both, OR engineers have done the same.
The speed starts in the high 40's then over a period of 2 weeks drops to well below the stated line speed, regardless of the connection (and to be honest even if it was wireless I wouldn't expect the drop to be so dramatic though I take your point). I should add the speed doesn't increase until someone resets it. The last OR engineer showed me the graph over a period of time and you can see the gradual decrease. He said the system was designed to constantly drop the speed if it thinks there are problems on the line until it finds a speed its happy with. Thing is there are no problems on the line according to 5 OR engineers...
can you enter your phone number and post results remember delete number will show estimated connection speed range https://www.broadbandchecker.btwholesale.com/#/ADSL
Have you tried the test socket with a filter to see if that helps stability?
