The support for fibre is lame to say the least and after texting I got a message to say all is well and so I have to pay £60 a month for a 150 Mbps connection. How can I take this up with BT?
are you dealing with the FTTP TEam 08005874787
FTTP once connected , provides whatever speed profile you pay for , it’s not like any automated intervention ( reduction) is applied to aid stability, like ADSL or FTTC, if you are not getting what you pay for , and your provider has checked that you are on the correct profile ( in other words they check that your account is set up as 900Mb ) then provided your PON light is lit there isn’t much else to check, your ONT serial number is what the headend ‘uses’ to deliver the appropriate speed, so unless you and a neighbour swapped ONT’s , that’s the only way it conceivable that you could get ‘their’ speed and they get ‘your’ speed, so even someone swapping things around externally is not going to give you the wrong speed.
If your link is ‘up’ , your account is set correctly , and your ONT serial number correctly recorded for your address, the speed you pay for should be at the ONT.
Any speed test you do needs to be on a wired device and obviously capable of using Gb speeds.
You can eliminate the router ( it’s always possible the router is faulty ) as the issue by connecting directly to the ONT and setting up a PPPoE session.
What have you done to prove it’s not your own gear limiting speeds ?
Using a Unified router connected to the unit on the wall and that can run its own speed test so not a wifi or home network problem.
Doing a browser based speed test will give a similar ballpark figure - just over 100 Mbps.
There are many posts like yours on this and similar type forums , especially when using third party kit , where the expected speed doesn’t materialise , inevitably it’s the users own kit, either incapable or incorrectly set up, as already explained, to eliminate any element of doubt , connect a suitable device to the ONT directly , set up PPPoE session and run a speed test.
Have you attempted to use the SH2 and run a test ?
