Issues with FTC

I've been experiencing a lot of issues with my fibre connection lately.  Usually when VPN-ing into work using SoftPhone, WebEx etc.  Connection drops, lots of distortion - but I wasn't sure if that was the company VPN or the apps I was using.


Today I've had major issues connecting to games and Netflix during the night, with extremely slow buffering, packet loss etc.  I checked the speed via my router and it seemed extremely low.  So I've rebooted and it's still showing the following:


5. DSL uptime: 0 days, 00:06:31
6. Data rate: 7735 / 42051
7. Maximum data rate: 7735 / 47805
8. Noise margin: 5.9 / 7.2
9. Line attenuation: 33.7 / 21.4
10. Signal attenuation: 34.5 / 19.5


It doesn't look right to me?  

It's not been right ever since Openreach sub-contracted to put in a new cabinet which took many weeks and included me losing phone then internet loss for about 4-5 days.  Mostly I haven't seen too much of an issue with speed (until today) but the quality of the line is definitely worse.


Next steps please?

Re: Issues with FTC

Did a BT speed test - 35M down, ~8M up, so no issues there.  It wouldn't go to the next page to run a detailed analysis though - tried twice and each time I received a message (pretty quickly) that it had timed out.


Oh and I should mention that, apart from Netflix, work VPN and main use is via ethernet, not wifi.

The banding would indicate that there's something out of place and so we'll more than likely need to get an engineer out to investigate.


Before we do that, though, we'd advise to utilise the test socket for around 48 hours to see if you see any improvement. If so, we can reasonably confident that it's an internal issue. If not, we'll raise the issue to BT Wholesale and arrange for the engineer.


Please let us know how it goes.
