If you have a good line then unless you are very close to the cabinet the DLM will automatically adjust it to 3dB, so this is perfectly normal unless you are getting excessive errors.

Hi @DOC1
Thanks a lot for reaching out, the SNR margin on your line seems fine given the line length, although on our end, the odd disconnection is apparent, especially last week, you'll see these on the visual radius which I'll link below. While the speeds on your line appear to be fine as well, line issues have been detected on our RRT.
Going forward, if you haven't already, please plug your router directly into the test socket, which lies behind the faceplate of your master socket and see how your connection fairs over the next few days, if your service keeps cutting out, please let us know by heading over to faults.plus.net, and raise this with our Technical Support Team.
When testing also, please avoid using any extension cables and sockets.

I've asked the mods to merge your new topic into your existing one Here.
If you're still getting drops in the test socket, I'd head on back to faults.plus.net to finish raising a fault for further investigation.

No problem @DOC1
If you can post back once you've raised the fault, we'll make sure that's picked up as soon as we can

Hi @Gandalf
I have received a text message saying ' To progress my fault an engineer needs to visit and if the fault is with my internal wiring or equipment a £65 charge will be applied '
Does this mean that they cannot see any fault at there end? And its possibly at my end ?
Would I be better off just removing from the test socket and putting everything back to how it was as £65 is a lot of money.

Hi @DOC1
Thanks a lot for your response. The reason I sent out that SMS was because while disconnections are apparent, there are no definitive faults on your line which have been picked up on our tests. We'd therefore ask you to conduct some checks on your side, and if the matter has still not been resolved, we'd then look to arrange an engineer appointment.
Saying that, we've noted that you've had your current router for over 2 years, I'd be happy to process a new one to be sent out to you prior to raising this issue with our suppliers? Let me know what you think and I'll get back to you.
