Well, my router resynced at 1 am in the night without any speed change. The only thing that has changed is IP and DNS. And now DS SnR is 5.4 dB at 6pm, don't want to know what it would be at 10pm. No latency increase either.

[N0STIE]

SnR is 4.9dB atm, is it really allowed to be that low? Not experiencing any issues though.

[Starman]

My line has been sat at 1.5dB DS for 7 days so far since an area wide power cut - wouldn't worry too much

[kitz]

4.9 should be ok. 

What is your error rate like, thats more important.   DLM works on the amount of Errored Seconds.  (E/Sec).

I ran a line at 3dB for many years - it all depends on your individual line, but theres quite a few of us here who see SNRm below 6dB at various times of the day.

Don't know my amount of ES. TD-W9980 only shows Errors (Pkts) - no idea what this mean either.

You may be able to get your Errored Seconds (and more) if you use ejs StatPOSTer

If youre struggling to set it up open a new thread in the router monitoring section and someone will be able to help you.

From memory you must be using port LAN2 LAN3 on the TD-W9980 to the PC you're running StatPOSTer on, otherwise it wont work.

Already done, kitz

By the way my router just resynced and something happened that I'd never expect to happen once again. It happened to me once, but then I was getting over 1000 ES/hour and DLM intervened just few hours after and reverted my latency to 12ms then I was getting about 700 ES/24hrs and it was fine then G.INP arrived I don't think it will stay that way though  but

Back on ADSL2+ I used to run on a 1 dB SNR margin with a DG834GT, one of the best at the time. 19 Mbps sync on a 30 dB line.  D

[William Grimsley]

Holy smokes! I was thinking 1 dB might have been possible on my line, but then my connection used to drop out at 6 dB most evenings... LOL.

[loonylion]

I used to run 1dB on a 50ish dB line. It only lost sync about once a week.

[William Grimsley]

What sync rate did you get as I had a a 50 dB line...

[loonylion]

around 5Mbps using G.DMT

[William Grimsley]

Oh, that's not good. I got 5 Mbps at 50 dB on an SNR Margin of 9 dB...

[Chrysalis]

its good and bad, to have it holding at 1db was defenitly good for a 50db line, but the sync rate was poor.

my 50db adsl line which i made a lot of noise about at the time was extremely unstable, it did sync at about 3000-6400kbit at 6db in the day (3000 isnt a typo, had huge snr swings), but the stability was extremely bad, and required heavy DLM intervention which still didnt full stabilise the line even at 15db and interleaving,   

The line was quite stable tho when I was on ukonline utilising SRA, an excellent game changer technology for bad lines which sadly was not used by any other isp's only ukonline.
