Infinity2 dl 1Mbps up is fine :/

Question

So my Infinity has been ok since install a while ago. Recently dropped from 50 to about 30 then yesterday dropped to about 4 down to 1.1
Up is between 14-18 so on target.
Advance test ip profile is 63Mbps
So I spent 5 hours on online chat support testing testing . Usual issue of can't do anything you must be wired to router. Made no difference.
Sent a screenshot of the 2nd part of the test speedtest.btwholesale.com and tech said wasn't a BT test! Hmmm
So the lines apparently fine after they have run tests and they can't do much more and will call back tomorrow to try another speedtest as it was showing busy.
Fingers crossed it's ok tomorrow more like they don't have a clue what's wrong and keep getting me to turn stuff off and re run speed tests :/
They said if I request an engineer it's my cost!
Now I'm not daft and do my companies it so know enough to suspect they have messed something up somewhere but how can the line show to fine:/
Nothing new or changed in my house.
Seems to have happened to others this.
Any suggestions?

Have you checked if there are any problems with the BT network in your area.

If your IP Profile is where you would expect it to be this would tend to indicate that DLM (Dynamic Line Management) has not detected any faults on your line and lowered your speeds. I could be a fault at the exchange or a fault with homehub or modem.
Do you have a separate Openreach modem. If you do you could bypass your homehub to rule it out.
You can make a direct connection from your PC to the modem which will eliminate the homehub. Follow this guide to do that. Use your computer as normal and run a speed test. If it comes back OK then you know it's a faulty hub.
Step 1: Remove the homehub from the modem
Step2: Connect your pc/laptop into the modem using LAN1 port
Step3: Open network and sharing centre on windows and click set up a new connection or network
Step4: Connect to the internet then click make a new connection Broadband PPPoE
Step5: Username [email protected] and the password as BT
Step6: connect, If it doesn't,keep pressing try again until it does.
