Could my speed increase


[link to this post]
 
Hello folks, since having fttc installed back in December, my speeds have dropped by approx. 10-15m. Looking at the below stats, can anyone advise where the problem may lie? Or is this simply a case of crosstalk now more people in the village are connected?
Cheers!

Would seem reasonable that it's crosstalk.

What speed range estimate were you given?

As far as I recall, more or less 76/20 when I first signed up. BT checker figures have sinced dropped so ISP won't investigate as a fault.

It looks banded to me

Does the sync ever change from 59997?

Apologies for my ignorance. Banded? What does that mean. Cheers!

Your sync speed is capped at 60 Mbps

Agreed. With an attainable of 62meg though, there'd be little to no gain from a reset.

OP - is your modem/router connected to the master socket, or an extension?

15dB attenuation would normally get mid 60s to mid 70s depending on noise levels. Your SNR of 5dB suggests that there is a lot of noise being picked up on the line - potentially from cross talk and that is what is pushing you attainable and sync speeds down.

Always worth checking that you are not creating the noise yourself - trying powering everything off in your house including fridge/freezer, boiler, and making sure devices are not in standby by turning off at the sockets. Just have your modem and PC running and monitor te SNR before and after. If that make little difference then there is little else to do.

Connected to master socket via NTE5 faceplate. No extensions running from master socket. Thanks for all your info. people. Speed dropped around April/May time and I don't recall anything changing in the house at that time. I will do as suggested though to rule out something internal causing the noise, though I suspect I was one of the first connections at the FTTC cab and as more and more people in the village have signed up crosstalk has increased. Presumably g.fast will help as and when it gets rolled out? Have to say I'm not holding my breath though, it took long enough to get FTTC.
Thanks again all, always worth having 'expert' opinion on these things.

Cheers!

Depends how close to the cab you are for G.fast. That's if it'll even get rolled out on your cab.
