I had 2 resyncs yesterday afternoon, currently no idea what caused them,, but I dont appear to be on a new DLM profile, was close to 100 days uptime, shame. Given both were within 10 mins of each other I suspect an engineer at the cab.

--edit--

My US snrm has dropped a bit so I wonder if was the DSLAM enforcing a new UPBO.

Odd it looks like a retrain reason 0 which is what you get when you turn off the modem for 30 minutes and then on again LOS: Loss of Service and only see 1 resync on MDWS at 16:16 27/1/2015  :-\

to check when I think my line was on G.INP, check on MDWS my username for first week of sept when I had low attianable before my fault was fixed, I Was on fast path on the DS with FEC enabled.

Seems it has kicked in on my connection now. I was always on fast path before, my pings seem unaffected (Please not my first hop has always been high as its the plusnet gateway in London and I am in north Wales so the first hop is actually most of the country.

This is on a HG612 unlocked using H-Wolfs build.

yeah new g.inp fields get added, it be nice if the modem stats tool can be updated to look for these values.

once HG612_Modem_stats crashes then you will know G.INP is active on your line ::)

I'm hoping to get G.INP once I get up to the top of the long ladder my connection's in at the moment. 49Mbps cap at INP 7 with a maximum delay of 16ms (actual 11ms) on downstream, but about two days ago DLM made a positive change for the first time in a while since unplugging the ASUS. It was INP 8 with a 44Mbps cap before the positive change.

Currently using the Fritz!Box 7490 which is working quite nicely. Also reports whether G.INP is active or not via the web UI, and I've just found out how to get more detailed stats from telnet earlier this evening (if curious then see here for the output and some graphs I made for QLN and such). I doubt I'll be returning to the ASUS and will probably keep that in storage.

Do you have any equivalent output (--stats and --pbParams) from before G.INP kicked in? It'd be educational to compare them...

Hi unfortunately this is all i could find, Its the graphs and modem stats log. Unfortunately i don't have a Plink log or equivalent from before (i must have deleted them)

Thanks.

I'll try to work through them with a copy of the spec, and see what I can work out!

I had a resync last night and I'm now seeing INP at 5 (from 3), and interleave depth is at 973, opposed to 509 yesterday.

However, I'm now syncing just over 3000kbps higher with a higher snr margin  :-\

Yesterday - (When I last checked about 3pm) Sync - 35248kbps, SNR hanging around 3.2

Today - 38464kbps, SNR 5.7. Max attainable has jumped up to 42628kbps too

I know I need to setup 24/7 monitoring to see what's going on with my line properly it's just getting round to setting it all up  ;D
