DLM Reset Issues - Advice Needed

Hi all,

 

Looking for some advice regarding DLM on Infinity 2 line. I had the DLM reset on the line as a few power cycles by myself had knocked me onto a lower IP profile and enabled interleaving, essentially doubling my ping times (dreadful for online gaming). My fault I know, but I wasn't aware of the pain that is DLM coming from ADSL fastpath to FTTC. Before that, I had 2 months of great speeds and ping times. DLM reset was done by engineer Friday 13/05/16 and all looked great - back onto high sync speeds and nice low pings.

 

Waking up this morning however, I see that the Hub has dropped connection overnight, sometime around 5am. Is this DLM again? Does DLM actually drop the connection if it makes a change? There doesn't appear to be any drop in sync and interleaving doesn't appear to be on. I will post logs below, as well as general stats (I believe the line drop event begins with the 5:12:12 PPP LCP Receive Termination Request (NONE) event). Also worth mentioning probably that I'm only 400m from exchange, according to the engineer. My concern is that DLM is going to continually drop the connection and I'm going to end up with interleaving back on in the near future. Any help greatly appreciated.

Re: DLM Reset Issues - Advice Needed

DLM may disconnect you but I would not worry
Looks like your speed is as good as it can be and GINP is off. This if your cabinet supports it is applied before GINP
Just let it go and stop worrying

Re: DLM Reset Issues - Advice Needed

Where do you see G.INP on/off in the stats/logs? Sounds like something else to look out for going forward.

You dont have it you are at max 79987 and your profile is fully open
If GINP was on rate would show as 77.34 in the wholesale sleedtest

Re: DLM Reset Issues - Advice Needed

Cheers for the input. What is the PPP LCP Receive Termination Request (NONE) event though? What has actually caused the line to drop? From my POV the line has been stable with no issues since the reset, but something has caused it to drop at 5am this morning.

Re: DLM Reset Issues - Advice Needed

That is the network telling the router to disconnect and reconnect. It doesnt count towards DLM penalties
No idea why is doing it just leave it alone

Re: DLM Reset Issues - Advice Needed

Excuse my ignorance Barry, but what's the TR-069 update issues? If I am to ditch the hub, what would you recommend having in its place? Everyone I've spoken to at BT seems to think I should be having uptime of weeks and months.

Re: DLM Reset Issues - Advice Needed

you can buy a separate modem from auction and use the HH5 which many find a good solution or aternatively get a 3rd party mode/router like tplink 9980
