No.

Several posts using incorrect terminology in this thread, along with guesswork, and others wading in with their own retelling of their own issues, with no bearing on the OP’s problem.

Sounds like your line was cut and is now impacted due to a splice.

Odd comment. A single extra joint done correctly (it's hard to get wrong) will have no noticeable impact on a lines sync.

It isn't exactly detrimental to a line to have joins/crimps or everyone on copper would be screwed.
Count the number of footway "joint boxes" (the clue is in the name) on the average pavement and how often they are spaced.

Most lines probably have half a dozen joints between cabinet and home. Lots have many many more.

Can you please advise of my misdemeanours so I learn and don't do it again

Edit: Sorry misread guesswork as guess who and thought I had messed up like I normally do

48 mbps should be plenty for two HD connections and a download. I got 4K programme on TV with adsl via Amazon.

Whichever is the most important then carry out the other operation at a different time.

As a process of elimination putting you back on your original DSLAM port to see if the speed would go back to what it was would be a good start but I don't know what the chances of that would be. Are you sure nothing else was changed during the very first visit.

Streaming 4K (UHD) - Netflix/Amazon/Disney can stream 4K in around 25 Mbps. The likes of BBC which like to do things differently may need more, if you can find any 4k content.

Live broadcast 4K (UHD) - This is where things are more complicated, and may need 50 Mbps or more. (YouTube isn't real "broadcast").

Amazon use much higher compression. 15 mbps was enough to get the programme.

Max attainable should really be 100Mb or so at the cab. 80Mb at the cab used to get marked as faulty but it’s meaning that they have so many faulty ports that now 80Mb is allowed at the cab. So OP is out of luck.

Its a shame the acceptable standards have been allowed to slip like this, its always the customer who ultimately suffers not the ISP or Openreach who still get paid the same.

Spliced is just an Americanism for jointed. A lot of American terms have crept in in recent years.
