Incredible fluctuations in fibre speeds

We've been with plusnet a number of years now and were convinced (with a solid offer) to upgrade to Fibre. I was attracted to it because we do a chunk of streaming in our household via Now TV and NFL Gamepass and I thought I could avoid some of the buffering issues we suffered on standard broadband.
Well since the switch the speeds we received vary terribly. Occasionally we hit 30 mbs + but usually its in the 10's to mid teens. Thats usually. There are times for no reason it drops under 10 and tonight it hit a new low of 1 and a bit mbs according to speedtest !
Watching NFL Gamepass today has mean't dropping quality to levels I used to us on standard broadband and even then I'm getting buffering.
As I write its crawled back up to 9.73 mbs.....30 mbs is a dream it seems
I've raised tickets and had the reports back saying there is no problem when there obviously is.
Any ideas or suggestions of things I can do (I've used all available speed tests and the differences are negliable) ????

Have you seen this thread at https://community.plus.net/t5/Fibre-Broadband/High-packet-loss-and-other-DNS-issues/m-p/1354749#U135... because you may be suffering from this issue?
The basic conditions are
- High packet loss
- You are connected to the Plusnet new network (I'll explain how to test below for that)
- You have not bought a static IP address from Plusnet
How to check for the new network?
Look at http://users.plus.net/@gateway/ if the gateway name shown contains the letters "-IR" then it is the new network (this test works for non static IP users only)

core2-hu0-18-0-0.colindale.ukcore.bt.net (62.172.103.16) 4.568 ms
Is what I got from the gateway check which is all gobbledegook to me being honest.
Just tried BT Whoelsale test....still under 10mbs

That is the new network (Plusnet haven't updated some fields to give back a human readable result)
Are you using the Plusnet Hub One router or did you supply your own?

According to the above their test failed due to 100% packet loss.
BT Wholesale had an error after doing a basic speedtest too.

Not good, I ran that test and got
Packets Lost{ i } Latency{ i } Jitter{ i } 0% 13.516ms 0ms
But I'm not affected by the issue so would expect a clear test result I got.
You may want to add your complaint to the big thread linked above

That figure may be highly misleading as apparently the test pings the host IP address. If there is nothing set up to respond to pings (which will be the case when only the Hub One is used) it will report 100% loss as the test will not work.

At least that one states it can't do it rather than incorrectly reporting 100% loss.
What is the other error?

The BT test now actually completes, this is the result there right now.

Well I wish that Freeola put better instructions in place as it just says
What does this Broadband Line Quality Test actually do?
The line test above works by sending packets from our server straight to your computer and reporting as it is doing so. This allows our test to see if there is any packet loss, what the average network latency of your line is and provides a jitter measure. This accurate line quality test can alert you to any potential problems on your ADSL line.
So naturally I assumed the browser was handling the packet test.

@SpendLessTime this is what I get when I disable the DMZ on my Hub One (normally a Now TV box lives there)
An error has occurredUnfortunately the line test has failed to complete, due to 100% packet loss. This means that we were unable to connect to your computer via a ping request. The most likely cause of this problems is firewall software that is set to block ping requests. This firewall software may be installed on your computer, or built into your router (if you use a router to connect to the internet).
That is wrong as well as nothing is blocking the ping requests, I just don't have anything set up to respond to them.

Well today we have varied between just over 30mbs....to just over 6mbs....to under 1mbs....to 5mbs right now.
Laggy webpages....I really don't know what to do !
Am I naive to say I didn't expect this on "fibre" broadband or do I take it further ?

No this is not the service you should be getting, something is very wrong.
You need to take it further.
Start with the basic tests for phone and FTTC. If at the end you have yet to submit a fault then do so for the FTTC. The links are in the guides I've linked to below.
First thing is to check for a phone fault (if Plusnet provide the phone start here https://www.plus.net/help/phone/phone-line-troubleshooting/ ) If you do have a phone voice fault, report it as such and do not mention any broadband issues. And then when that is fixed, see if the broadband is better.
Then if still not solved (or no phone fault is in evidence) start with the FTTC guides at https://community.plus.net/t5/Fibre-Broadband/Fibre-Fault-Guides/m-p/1156188#U1156188
