Hi to all,

I just came back to BT last week, engineer fitted new drop line, wiring and master socket

I told the engineer that I had a lot off issues in the past and had found that 21cn on 992.3 (adsl2) with interleaving had been found to work the best with speed and reliability.

however, despite the info, he connected me on ADSL Max as per BT standard protocol for longer lines,which peeved me off as I had only just came back.

now here I am with a 9.5 snr on fast path with a much slower sync.

The router had been left alone, I reset it an hour ago (waited 30 minutes) hoping the snr would pull back down to 6 and turn on interleaving, but it has stayed where it is.

I am afraid now that because of new line training, that the Dom has decided this is the best it can do, which is incorrect.

I am happy enough to give g.dmt a chance to see how it fairs this time, I was just hoping to request a MOD to reset line back to 6 SNR and apply the interleaving.

Hopefully the training period with interleaving applied the snr will stay there, but of not can go back to my test and tried setup as before.

From your stats the max down speed is only 2.9mb so unlikely much change even if adsl2. Up speed would be far better on adsl2

Thanks for the reply,

I think that’s dlm has kicking in giving that as a max, when it first connected the at 6snr, the max was 3600, a few days ago it changed to that figure

Re: New customer

w4481 — Sat, 07 Nov 2020 15:49:24 GMT

Also, just to note, I always get a sync of around 3500 before, even 4 in the summer

Re: New customer

w4481 — Sat, 07 Nov 2020 15:54:28 GMT

I’m assuming that max rate is based on the current snr of 10

Re: New customer

imjolly — Sat, 07 Nov 2020 16:39:07 GMT

The max data rate is best your line can do. The higher noise margin is due to your connection speed being below thee attainable rate

just run dslchecker so we can see what is available to you save the guessing

Thanks for response again, the wholesale check is saying Adsl max 1- 2.5 and Adsl2+ 1 - 3.5, so it is obviously openreach putting me on max that has slowed things down.

the 21cn previously I had must just perform better.

in that case, since I had actually requested 21cn from the start, maybe the mods could arrange a switchover for me.

Just to note, it does seem rather odd that my neighbour next door, with their line running off the same pole has a current sync of 4.6, when I checked they are on adsl max as well.

openreach fitted whole new line to my house too, so can’t be any errors that side and have no extensions or anything in house either, drop wire straight to the master.

I find it hard to understand how the house next door to me has nearly twice the speed

please can you post full dslchecker results you can use camera icon

Try phoning CS on 150 and see if you can get them to help you move to adsl2. Probably not much change to down speed but certainly faster up speed

no 2 lines are the same so your neighbour could have a better line than you all the way back to the exchange

Re: New customer

w4481 — Sat, 07 Nov 2020 18:44:59 GMT

Sure, I’ll will post it when I’m back home.

I don’t mean to undermine, but I know the adsl2 on 21cn is faster as I had it the last few years with another ISP and had steady line syncing around 3500 always. Starting to regret coming back to BT unfortunately . I will try CS, but I’m pretty sure they will be as useless as ever, so was hoping a mod would issue the switch.

thanks again for your input, much appreciated

imjolly — Sat, 07 Nov 2020 18:55:09 GMT

If you try CS and hit a brick wall then post back and we can see if can get more help

hopefully you will get the 3.5mb down speed with your current 54db attenuation I would hope maybe 3.9/4mb on good line with no noise but will see

Re: New customer

w4481 — Sat, 07 Nov 2020 19:01:58 GMT

Will try and see how I get on, thanks for your help

Re: New customer

w4481 — Sat, 07 Nov 2020 21:18:33 GMT

If I could just ask one more question before contacting CS tomorrow, if you don’t mind 😊

I have a billion router with the adjustable snr value.

I just wanted to query should I save a lot of hassle and just lower the snr down a few myself to achieve a better sync?

My concern is that the Dlm won’t like this and mess it all up ?

Or if I was just to wait a while and see how it goes, will the Dlm maybe lower the snr itself in time.

thanks again

i would not make any change just now and leave the hub connected and see if you can get CS to move you to adsl2. On adsl2 should reset your noise margin to 6db with corresponding speed. If you can then maintain a stable connection with no reset then DLM will reduce your noise margin down to 3db which should boost your down speed - no need for billion

Hi,

finally got around to ringing CS and was a rather painful experience lol kept asking what the fault was etc, I was trying to explain no fault just want moved to 21cn as get better speeds up and slightly better down, don’t think she understood what I was talking about and was trying to book engineer lol

If it wasn’t too much bother, would a mod mind picking this up and put the change through for 21cn, preferably on adsl2 992.3, save me a lot of phone time with CS!

i Have asked mods to lend a hand but they are busy so could take longer than normal but they will get back to you
