Hi,
I'm on a fibre package with BT (Fibre with BT Halo 1) that has been rated at estimated max speed of 40-50Mb for the last few years.
Suddenly (more or less overnight, I think), we're now rated at 20-23Mb max download speed - i.e. something upstream of me (cabinet or exchange) has changed and now this is the fastest I can ever expect.
This is...rather frustrating to say the least.
Can someone in the know tell me how common it is for BT to basically halve your connection overnight with no communication / warning? And whether I can expect it to return to the old baseline?
Given this new lower estimated max is what I am seeing on BT.com and across all the broadband / exchange check sites, I am thinking it's a deliberate downgrade due to capacity constraints, rather than a fault.
Thanks!

Re: Broadband package max speed has been downgraded?
welcome to the BT community forum where customers help customers and only BT employees are the forum mods
in order for the forum members to help please can you post the stats from your router (if hub enter 192.168.1.254 in your browser) and if HH5 then go to troubleshooting then helpdesk and if HH6/SH2 then advanced settings then technical log information .
Have you tried the quiet line test? - dial 17070 option 2 - should hear nothing - best done with a corded phone. if cordless phone you may hear a 'dull hum' which is normal
enter your phone number and post results remember to delete number https://www.broadbandchecker.btwholesale.com/#/ADSL
Someone may then be able to offer help/assistance/suggestions to your problem

Re: Broadband package max speed has been downgraded?
Is your download speed actually slower or is it just your estimated/guaranteed speed that has been lowered?

Re: Broadband package max speed has been downgraded?
Many thanks! See below for router / exchange info.
Max estimated speed from most providers now seems to be 20Mb. It has been 40-50Mb for years, so I don't know what is driving this.

Re: Broadband package max speed has been downgraded?
This is now what I'm told my guaranteed / estimate is, and is in line with speed test results.
Never had any problems with my connection previously, which was always 40-50Mb in line with previous guaranteed / estimate.

My download speed is also lower, in line with the new estimate / guaranteed speed.
No, your estimate is now lower in line with your actual speed. I.e, it is reflecting reality.
However, your speed is lower than it should be and is below your handback threshold. Try connecting to the test socket behind the removable faceplate of the master socket with a new filter and see if your speed improves.

Re: Broadband package max speed has been downgraded?
So there might be a fault rather than a deliberate downgrade?
Apologies the workings of this is pretty opaque to me, so forgive my ignorance!

Re: Broadband package max speed has been downgraded?
Its possible you have a disconnection on one wire of your phone line. Can you get dial tonr when you plug a phone in?
One wire disconnected usually causes about half speed.

Well, somewhat embarrassingly, a home hub reboot seems to have resolved it all.
Sorry folks! Totally misread what was happening here. Appreciate the guidance!
