Okay, I know I'm someway short of the 2 week honeymoon period but, from much experience, I can tell I need Plusnet to make a few adjustments or investigate.
I just upgraded from Unlimited Fibre to Unlimited Fibre Extra.
Before the upgrade my router was syncing at circa 38-40Mbps. After the upgrade the sync is 71.52Mbps. Super.
I noted that actual throughput was below 1Mbps for the first few hours, but upload was correct at just under 18Mbps.
DLM got its teeth into it and the speed went up to 40+Mbps after a couple of days. I expected a bit more but would have been happy with this, however it's dropped considerably and remained low. (Apparently, according to BT during the last round of troubles, my physical line quality as a good as they come.)
DLM seems to have stepped down to a slower throughput than I had before the upgrade - which makes no sense since nothing has changed aside from the upgrade. Current throughput struggles to beat 20Mbps. Much less at peak times.
Some points to note -
Some time ago a Plusnet tech had to manually adjust my line's fault tolerance to get a better throughput. At the time this worked splendidly.
Some months ago I was given the runaround by both Plusnet and BTW - several pointless engineer visits - before anyone would believe I was on a hot VLAN. Once this was changed throughput at peak times improved beyond belief.
No engineer visits are required - nothing has changed at this end aside from the upgrade so I'd rather not entertain the usual round of 'check the sockets' etc. This has all be done - please take that as read.
In due course, can anyone at Plusnet look into this please?
Fixed! Go to the fix.

Thanks for getting in touch @DocDelete
I'm sorry to hear that you've had issues with your speeds since your upgrade to Fibre Extra.
It looks like for some reason the connection profile on our end has been set to 21mbps which will have been restricting your throughput speeds.
I've now corrected this for you and dropped your connection so you should be picking up faster speeds now.
If you're still having issues let us know

Thank you @MatthewWheeler - just checked at 36Mbps. I hope that DLM ups that a bit more over the next few days. I think the 'minimum guaranteed speed' reads at 50.9Mbps.
Likely?

Just clocked at 60.2Mbps so I guess that's my answer!
Fingers crossed.
Thanks again for looking into this for me @MatthewWheeler

Hmmm. @JOLO @MatthewWheeler - struggling today, just over 30Mbps, tested several times since this morning. Back to pre-upgrade speed after we witnessed 60+Mbps for a sustained period. Any clues?

Thanks for getting back to us @DocDelete
I've retested your line and I can't see any cause for this on our end.
If you're still having issues please follow the steps below we can investigate further please connect your computer/laptop to the router with an ethernet cable and run the BT Speedtester service at http://speedtest.btwholesale.com
You must ensure that you have no other programs running at the same time such as streaming, general browsing and the most common one is antivirus programs downloading updates in the background. This must be done on a wired connection and not wireless Once the initial result is completed please click Further Diagnostics.
Please type in your phone number and click run diagnostic test. This will run a test and send the results to the server for investigation

Thanks @MatthewWheeler - so is BTW's speedtest working again now? From more than a year ago it had issues with not performing parts of the test correctly. That's not just me, but I believe a widespread comment.
I have an automated programme on my laptop, wired into the router via RJ45, that runs a download test every so often and charts the result. I'll set that going too.

Hi again @MatthewWheeler @JOLO -
Um, it seems I've been throttled down to <21Mbps again. A few hiccups over the weekend while multiple streaming showed up a lot of buffering. I've checked with a few random speed tests and it's not improving. I've run a regularly check for an hour or so with a wired connection, and the trend is enough evidence for me to contact you again. Pic attached.
Can someone have a look again please?
Thanks, Ken.

As testing your line isn't picking up this problem from here, we'll need to do some troubleshooting to try and narrow down the cause. I'd recommend starting with basic checks here. If these checks don't resolve the problem, the next step would be to connect your router directly to the test socket, which is under the faceplate of your master socket and seeing if the connection stabilises. This rules out internal wiring, face plates and extension sockets as being the cause. Please see the guide here for instructions on how to connect to the test socket.

Hi @EmilyD
Sorry, done all that. This isn't my first rodeo.
It's wasn't a line fault issue last time and it probably isn't now. Further, I have no other sockets, faceplates or extensions. The master socket is purely used for the broadband.
The sync speed isn't and has never been a problem. It's the throughput speed. Look further up the thread for the bit where PlusNet had throttled me down previously despite sync speed being 72.5.
Also - nothing physical has changed here. Last week the speed was fine.(Last year it took a stupidly long time to convince both Plusnet and BT Wholesale that I was on a busy VLAN, so rest assured all hoops have already been stepped through).

Additionally - I have a master socket 5c which isn't covered by your master socket tutorial.
Importantly - I have also swapped routers to check. No change. So, it's not a router fault.
The throughput speed at <21Mbps is highly suspicious and massively consistent. If this were a line or congestion fault I'm not sure we'd see this.

Thanks for getting back to us @DocDelete I'm sorry to see you're experiencing speed problems. From what I can see this looks to be due to a stuck profile on your account. I've fixed this for you now, could you reboot your router letting us know how your speeds look afterwards?

Thank you again @Gandalf - I restarted and we've leapt from 20Mbps to just over 70Mbps. Line quality here seems to be very good so it's always a clue that something else is going on!
The stuck profile has happened before. Is there anything that would cause this from my end?
If not, it's a shame I have to keep monitoring my throughput speed to catch this problem.
Regards
Ken.
