Ouch!!

Ikr! People say I don't have a fault, but what's even more surprising is that there are no downstream errors!

There is a BIG difference between a fault that an telecoms operator will dispatch staff to resolve and be able to fix and what the various error counters/handlers within the DSL stack will report.

Any Radio Frequency based medium has to tolerate errors, hence all the error correction systems, and while fibre optic may not be subject to RF interference many of the mathematical techniques are still employed.

I say you do have a fault.

But I also say you don't have a fault that's reportable. Or not last time I looked, anyway.

The trick is to realise is that there is no such thing as a perfect line. It just has to be "good enough" to carry the service being asked for.

Many engineers and researchers have spent years, decades even, figuring out how to get lines to transfer data in noisy environments with as few errors as possible.

Should it be a surprise that so many of these solutions actually work?

People keep saying that copper is obsolete. The trouble is that the DSP chips controlling those copper lines are most certainly not obsolete. They employ the state of the art of what we can get signal processors to do. The improvements we see in speed and reliability is a direct consequence of Moore's law, and the amount of work we can ask of our hardware.

My line has suffered 2 resyncs in the last 30 mins, with the reason apparently being "Reason: 4 CReverb1Misdetection" - not a clue what that means!

Also, my attenuation has jumped up from 18.5ish to 29 and speeds have more than halved:

Current Downstream Sync Rate is now 28817kbps @ 5.1db SNRM
Current Upstream Sync Rate is now 8173kbps @ 6.2db SNRM

I haven't got access to my stats from modem at moment but I am tenbyboy2 on MDWS.

Need to check if you have dial tone, if so, run the quiet line test.

I literally work 2 mins away from home so I need to concoct a good story to have to pop home for 15 mins

This has happened before but it's a pain it's happening now just as my line got the lowered SNR yesterday as it may now think it's too unstable do you think?

Working that close then I would think the excuse of "I need the loo" would be good enough to get out of the office

It's worth a try

Nah, your noise margin is still 5.1, so something has caused the speed to drop. It's not like DLM has took a huff and increased the margin to 20.
