Hi, we purchased BT infinity option 2 in January and everything has been good except for the home hub rebooting that has been mentioned on this forum.
What I would like to know is that I have noticed my noise margin has been slowly decreasing over the last few months which is also decreasing the max data rate too, does anyone know if this is normal for infinty? (noise margin was around 9db down when we first got it installed)
Crosstalk at work. I used to have a max rate of about 100mbps. Over the years as more people have taken up fibre my max rate has dropped to below 80 where sync rates are now being effected 😞
Your Max rate has not dropped that much and at least your SNRM is just above the target margin of 6.0dB when you start to go below 6.0dB then you need to start worrying.
Any ideas anyone ?
To me it looks like your download SNRM is having a battle with noise/interference and your probably seeing your down SNRM decreasing in the evenings and when the DLM starts seeing your SNRM going below a certain level you may get a lower re-sync which should increase the SNRM.
It's hard to find and cure noise/interference as some of that may be Radio Frequency Interference from broadcasting stations on AM which effect the Mid tones from 1680 to 1720, and there is also something call crosstalk when new customers get connected to your Cabinet.
If you think there is a fault then call it in.
