Drop in speed FTTC :(

[usermac]

I am gutted my connection has been reduced I was always connected at 80/20 but now the sync has dropped to 74.6

which doesn't seem like much but when you take into acount a further reduction from the IP profile my download speed has dropped to lows of 61.

I am on a short line about 150 metres from cab and exchange I have seen my line performed better than this.

I had an engineer visit and he said he couldn't find anything wrong with my connection and said that the he had done an snr reset so my line would find it way back to 80/20.

Has my line been banded I don't get it.

Which exchange and cab? You've cut that off.

From what you have posted you have lost G.INP hence the noise margin back at normal 6db. Just remain connected and DLM should activate and you will get increase in speed back

[usermac]

My modem does not offer me any other stats which kind is kind of unhelpful but It usually will hold connection well over 100 days and more so it is good in that respect.

I hope it is G.INP that just needs to be switched back on but
I was getting 6dB before on 80/20 ?

Connection time is only 5 days maybe there was other drops?  You just need to wait for DLM but need to ensure stable connection 

[pippincp]

It takes 10-14 days for G.INP to kick back in.

[usermac]

Nearly 11 days now

I think there was a couple of re syncs from the snr reset but seems to be holding now so

I will certainly have more faith in the DLM if it actually does put my connection back to the way it was but time will tell.

[imjolly]

looks like noise margin is reducing and will continue as long a no drops in connection apart from the DLM resets

[usermac]

It is not looking like the DLM is going to increase my speed even with a stable connection of just over twenty days.

The DLM is quick to take away connection speed but getting it to retrain is a long old process. 

I also think re transmission high is set on my connection which is further reducing the download speed.  I know it will probably be a no but can get an admin to check my line stats to see what is going on. This is really doing my head 😫
