Hi anyone with any experience in successfully and joyfully resolving a downward trend in broadband speed?
I've been speed testing every day and tracking performance. The pattern is periods of stability then a drop followed by another period of stability at a lower speed, etc, etc. In summary here's the average speeds since January:
19 Jan - 28 Jan 33Mbps
29 Jan - 16 Feb 29.2 Mbps
17 Feb - 28 Feb 26.8 Mbps
1 Mar - 19 Mar 24.3 Mbps
20 Mar 22.1 Mbps
are the speeds in your original post connection speeds or download speeds?
have you tried using the test socket with a filter to see if that helps with stability and therefore improves conenction speed at present it appears your drops in connection are increasing the noise margin above normal 6db resulting in the speed reducing
Thank you for the reply - any expert advice is most welcome! Let me see if I can answer your questions...
1) The speeds are 'download' speeds I believe. I have been using speedtest.net. I've been consistent in using the same test over time so I guess the downward trend remains a real thing.
2) Test socket with filter: I've attached a pic of the BT masterplate. I think this latest master socket plate includes a filter negating the need for microfilters. Is there another thing to try? If my speed is reducing over time due to noise margin then what can reduce the noise margin? How can the speed be returned to it's higher better performing starting position?
that is the newest master socket and of course is filtered. however that does not stop your internal wiring causing interference with your broadband hence why using the test socket with a filter eliminates your internal wiring from being cause of low speed. it also helps if engineer visit as you have eliminated internal wiring and unlikely to be charged callout fee of £130
the test socket is visible when you unclip the front of the new master - no screws to take out
So the test is unclip the front plate and plug into the test socket with a microfilter - sounds like a good plan.
What should I look for to confirm a positive (or negative) result?
You would need to leave in sockets for a time and see if helps stability which in turn is the start to improve noise margin and speed
you should also check that there no dial tone at any extension socket whether in use or not
