Help with my BT Infinity Service


[link to this post]
 
Hello, I've been having problems with my BT Infinity service for a few months now. Finally today thought I would ask for some advice. I first had it installed back in Feb 2011 and I was the first customer on the cabinet. Openreach engineer said my line was capable of reaching "The Full VDSL speed". Up until March the connection was reaching 40Mbps. Since then the speed has lingered around 15Mbps. I upgraded to the unlimited package recently as I was using more data and I hoped this would reset my IP Profile but no such luck. I just unlocked firmware on the VDSL modem but cant make much sense of the stats.

Connection Status
Help
Mode VDSL2
Traffic type PTM
DSL synchronization status Up
DSL up time 4360

Line Status
Help
Downstream Upstream
Attainable rate (kbit/s) 81156 30753
SNR margin (dB) 26.4 19.4
Line attenuation (dB) 0 0
Output power (dBmV) 13.2 -4.3

Downstream Upstream
Line rate (kbit/s) 17999 14999



I expect my cabinet to have many connections as you're lucky for ADSL speeds to go above 1Mbps.
Any help or advice is appreciated.

Thanks, Chris.

Modem is saying it can do 80/20 easily, but is synced at a lot lower speed.

Tried restarting the modem and grabbing stats as soon as they are available.

Is SNR margin still zero?

The lines rates at 17999/14999 in your original and latest posts look a little suspicious.

Do a few more reboots - spaced out by an hour or so and see what they say. If it comes back as 17999/14999 then you are certainly being capped.

SNR has gone back to 26.4 / 19.4 I'm not sure if this is good or bad?

I shall get back to you tomorrow regarding the restarts and keep an eye on it. Thanks for your help!

You should check out your ip profile before reporting the line fault.

Lots of spare noise margin points to it being capped most likely
