New FTTP connection, occasional drop outs

Had an FTTP VM connection put in recently, for the first week or so no issues but today it started dropping out and having checked the stats on the SH3 I'm concerned that the error rate seems incredibly high. The error counts are only within a few minutes of having restarted the SH3.

Re: New FTTP connection, occasional drop outs

Definitely something wrong.

Your downstream signal to noise is very poor.
Check connector inside and out (had any rain recently?). Disconnect and remake the connectors check the state of each.

If that doesn't fix it the you'll need and engineer.

Do you know where your local street side cabinet is? Does that look ok?

Re: New FTTP connection, occasional drop outs

Had some very heavy rain last week but not much over the weekend and it's been fine until today. I will eyeball the outside connections/street cabinet tomorrow and raise with VM thanks.

Re: New FTTP connection, occasional drop outs

I found a loose coax in the box outside which I have now snugged up, things appear to be back to normal although more inclined to believe it was a local fault that got fixed while I was out and about today!

Re: New FTTP connection, occasional drop outs

It's remained stable so far since I tightened the loose connection outside so currently all good.
