I've been experiencing issues with my ADSL connection for about 3 weeks now, when it had previously been fine and stable. My ISP is NowTV. The connection will drop multiple times per day - there is no rhyme, reason, pattern or logic to why it happens. It usually drops out between 5-10 times per day, but always reconnects a minute or two later.
It could drop out 3 times in 15 minutes or once in 6 hours - no logic to it. In fact from Monday afternoon to Tuesday afternoon this week it was pretty stable and didn't drop out at all. Then today it's been basically unusable. I'm working from home and am now getting a lot of grief from work when I drop off of video calls with colleagues and clients. NowTV have been able to see that I've been experiencing regular drop outs but have really only sent out engineers who can't find any issues.
- I've tried 3 different routers; all exhibit the same issues.
- I've tried taking the master socket faceplate off and plugging into the test socket with a filter; no difference.
- I've had 2 engineers round, both of whom have found no faults on the line, have traced the cable all along the outside of the building, back to the pole and back to the exchange. They can find no fault and no noise on the line.
- I've tried isolating every electrical circuit in my apartment at the fuse box, other than the circuit for the sockets because obviously the router needs power. Still the issue persists.
I began monitoring my connection with RouterStats-Lite about a week ago and have noticed wild fluctuations in noise margin, amid periods where it is stable - if high. These fluctuations often cause my connection to drop out, but not always. Take a look at some snapshots from today for an idea of what my SNR is doing:
I rent a small apartment on the 3rd floor of a moderately old building. Other than my mobile I don't own a phone, so nothing else is plugged into the socket. The only devices that use my connection are 2 laptops, mobile phone and an iPad.
Any ideas folks? Am I looking at REIN interference here? I'm really struggling to imagine where it could be coming from if so. Nothing has changed in my home, many other apartments around me in this building are also empty at the moment. I'm absolutely at my wit's end here, and I don't think my employer is particularly happy either.
Thanks for any insight!
