Speed slowed, possibly after Engineer visit?

Hi, I wonder if you can help please.

I am using the standard supplied modem router, which displays :-

Downstream: 16.49 Mbps
Upstream: 3.203 Mbps

I'm on unlimited the Fibre package and have been doing speed tests fairly regularly in case I need a record of any issues.

My speed was fairly stable at around 18-19mb download and around 2.5-3 upload. I'm led to believe I'm quite a way from the exchange as it's not great to start with. Openreach have been putting FTTP on the poles recently on the access road where I live, but my road only has underground cables and I've seen no work done in them as yet but that's neither here or there as yet.

My issue is that an BT engineer came out on the 01/04/2020 to fix a fault on the voice side (Data was unaffected). He renewed the connections in the grey termination box outside and replaced my i-plate and NTE5 with a new master socket 5C.

Since then my download speeds have tailed off to 14 or so and upload speeds are variable between 1.9 - 2.9.

I know its only 4 but when I only had 18-19 to start with...........


I have tried hardwired etc on different devices.

Any thoughts or ideas please?

Many thanks

This tells you what to do if the speed is lower than it should be. Plusnet will tell you what speed you should be getting if you don't know the number. For FTTC it is the distance from your property to the cabinet that matters not the distance to the exchange.

Sorry, should have added. Both Plusnet and BT previously gave an estimate of around 18-20mb so I know that the 18mb I had for a long time was about the upper limit anyway I expected anyway.

According to the BT Broadband Availability Checker the upper limit for clean is 24 and 15 low. Impacted is 23 high and 13 low.

Although the fastest observed VDSL speed was 15mb at the end of April, don't know if that's relevant or not....

I have tried the new updated BT wholesale checker and that seems to hang on the additional diagnostics, just like the old one.
