Just ensure you have disconnected the wire from all the sockets.”
Further update - the internet connection ground to a halt again last night
Observations:
It was wet and windy for most of yesterday
The router was reporting a download noise margin of 11dB and an upstream noise margin of 16dB
Now, this morning it is working again: Observations:
It has stopped raining overnight
The router reports a download noise margin at 25dB, and an upstream noise margin of 16dB
The attenuation levels as reported by the router were the same last night as they are now.
Can someone tell me what a typical noise margin figure should be (is a higher number good or bad? - since measured in dB - which is a log scale , an overnight change from 11 to 25 is a huge jump!)
Is there a poor connection external to the property? Water? We're on overhead cable to the property from a nearby pole, the wire was renewed 2/3 years ago from the pole to an external JB on the house - but the wire from the JB on the house to the first BT connection box inside the property is still the old wire - the wire looks as though it has seen better days! Could it have become porous and allow water in?
I've logged a call last night with Virgin Media who couldn't resolve the issue - supposed to phone me back today
