Thank you, they did reset it and it changed for 1 day, I will keep the billion connected as my plan is to maintain this connection as I want that DLM to notice , I work away and go on Monday for 3 weeks so will be interesting to see if it has changed when I come home, my main point is that interleaved that's applied even after one good day,my ping is 30+ and very annoying for gaming

I'm sorry you feel that way.  ??? 

Looking at you prior two posts, all I see is a service that is almost operating at its design maximum . . . 73 Mbps DS & 20 Mbps US. The fact that the signal to noise ratio margin is just over 12 dB for both DS and US is because your circuit is operating so well. Essentially you have that extra 6 dB as a "buffer" which would have to be "eroded" before service degradation would become apparent.

It is silly o'clock in the morning and I can hear my bed calling me, so I really don't want to review all of the previous posts to this thread. If you would please post a summary of the help you need, I'll see what I can do later today . . . Unless someone else responds before I am next here.

Even a top-grade ISP will have limits as to what they can do given the lack of control over the workings of DLM. If Black Sheep is around, he might be able to elaborate on this point. :-(

There are a lot of incredibly knowledgeable people on kitz, but sometimes it comes to a point where our top experts are occupied, and users' difficulties are such that an outstanding ISP is the way to go. (cracked record :-) )

Apologies for the delay in response.

here are the stats off MDWS

Is 456240DSF you?

Looking at those stats over the past 20 days.  I cant see any indication that that particular line has been reset.
INP has been at 3.0 for at least the past 20 days, and interleaving delay also hasn't moved from 8.

Im also confused because that line is showing a current sync of 57728 for the past 11 days which doesnt tie up with stats you posted above.

I was wanting to see what was happening with your SNRm and how much it varied over the course of the day, but I cant see any indication of that either, although there is a break in logging a couple of days ago. 

As said in a previous post I'd need to see your SNRm variance before commenting further, but going off your stats alone - certain DLM intervention can cause an increase in SNRm - ie banding -  I cant recall the exact figures off hand but Im sure one of the bands is in the 74Mbps region.  If you have been banded at 74 then that could account for the 73265 sync with an SNRm of 12dB.   Based on the hard stats youve posted I cannot see any reason why DLM should be coming down so hard on you.. and that is why we need to look at SNRm variance and the amount of errored seconds.

The other thing that springs to mind...  have you been swapping out routers and/or doing lots of resyncs?   If so DLM could be punishing you for that.



A warning that I may not pick up on this immediately -  I have so much family stuff going on right now Im not sure if Im coming or going... and am miles behind with forum posts :/

Thanks for the reply

Is 456240DSF you?  Yes that's my stats , I find it strange they do not add up ,the stats I posted are from my billion 8800 ,also I think may have had about 3 resets from swapping equipment and firmware upgrades but that was 3 weeks ago ,I was previously getting 74down and a ping of 12 now it's 60 and ping is 30 so that is what I am trying to resolve,I did think about putting openreach eci modem back in but do not want to DC . I will monitor it, thanks for your help

So not sure why such a difference between my billion and MDSLweb, also by 74down that was my speed test results

Sorry for being a pain,on a side note the chap that I know around the corner who is 79 is with talk talk and went around and done a firmware upgrade for him on his asus 66u,done a speed test after and his ping was 12ms,so I know my line is rubbish

Hi

If it's just a ping where you want lower times for gaming, please search forum for the different username to use, which should give you lower ping times more inline with what your wanting.

If you have static external IP, these will not work and you would need to revert to your username and password.

You should not have to repower your router, just drop PPP

I hope it helps

Many thanks

John
