Reduced Broadband Speed, Fault or Speed Capping

Hi, moved into new property 9 months ago. BT broadband connection  with speed between 75 to 72 Mpbs for 7 months then sudden drop to 61.23 Mpbs. The speed we are currently on looks suspicious in that it is exactly what the downstream handback threshold is in DSL checker. Has BT capped the line just above the point were we can’t complain? DSL checker says we should get between 80 to 67 Mpbs. Upstream is at 20 so not impacted. Set up at house same as when we could achieve high speeds, there is no extension. Home hub shows max rate of 74. Noise margins 6db. Is this anything folks have seen heard of before in that speeds are capped? If this is a permanent issue we are basically paying over the top for speeds we can’t get so would be better off down grading. We have an engineer appointment booked so hopefully it can be sorted but any wisdom to pass onto the engineer would be gratefully received.

Any noise on your line? 17070 option 2, best with corded phone.

Other than that the engineer will have the test equipment we don't have so will be in a better position to diagnose the fault.

Re: Reduced Broadband Speed, Fault or Speed Capping

Hi @CornRoadInver 

Welcome back to the Community and thanks for taking the time to post.

Sorry to hear that you are having problems with your broadband connection.

It's possible that your connection was dropping or unstable meaning that DLM needed to cap the speeds to try and make the connection stable again. If this is the case then the engineer will reset the line once he/she has fixed the fault.

Let us know how you get on with the engineer.

Matt

Re: Reduced Broadband Speed, Fault or Speed Capping

Engineer visit was today. Not brilliant as he was an installation engineer only so was limited to checking house wiring which was perfectly okay as expected, master socket was already a 5c so no work there, did a silent line check that was okay, checked main cable connection. Speed test managed 61.3, max with the first one only getting 32. He called service support and was told as this was within 70% of top rate that it was fine. No DLM reset or checking out with property. Only snippet that may shed some light is that the service support said that speeds had been faster but had dropped but for last month had been stable at around 60, and that the line was impacted with bridge tap so speed was actually within expected speed. Just a bit annoying that you had good speed to start but a few months  down the road it slows up. Hub still says it can get faster max rate not sure if the bridge tap is new to the line or not. Looked up bridge taps but info not clear were that would be on the line as I’m only 30m from the cabinet. Looks like I’ll need to keep an eye on speeds but a check of externally wiring or DLM reset would have given more confidence that all had been done to try and get back to the stated superfast 2 rates.
