Is upgrade to adsl2+ working?

[zipp37]

On friday my line was upgraded from adsl to adsl+2 but it seems to me that it is still working on normal adsl. Wondering if anyone might clear it up for me?

Router: Netgear DGN2200
connection speed:  downstream 8064 kbps, Upstream 448 kbps
line attenuation: downstream 35.0 db, upstream 15.5 db
noise margin: downstream 12.3 db, upstream 23.0 db

Speedtester results:  Download speedachieved during the test was - 6555 Kbps
                             For your connection, the acceptable range of speeds is 2000-7150 Kbps.
                             Additional Information: Your DSL Connection Rate :8064 Kbps(DOWN-STREAM), 448 Kbps(UP-STREAM)
                             IP Profile for your line is - 7114 Kbps


                             >Upload speed achieved during the test was - 365 Kbps
                             Additional Information: Upstream Rate IP profile on your line is - 448 Kbps

I was hoping for better figures but this is not what is bothering me! In adsl settings i can set the router to auto, adsl, adsl2 or adsl2+.
If i set to auto or adsl it works as above but if try to connect via adsl2 or adsl2+ the router just doesnt sync at all. Does this mean I
am still stuck on Adsl?

Thx
David

When I installed an ADSL2+ router here, it connected to that automatically, so I would wager your connection has not been upgraded for some reason.

How do you know your line has been upgraded? LLU connections support ADSL2+ always, I believe, but with normal BT lines it varies between exchange. If you are going by BT schedule dates, then they are very unreliable. Either way, it seems you're still on ADSL Max.

[mervl]

AFAIK the 448kbps upstream indicates it's still ADSL (not ADSL2/2+). You'd expect upstream to rise to the 600-1200 range. Put the relevant details from your router into this to see what could be achievable for downloads: http://www.farina1.com/adsl/ .

Again I gather upgrading of lines isn't automatic on the upgrading of the exchange. It has to be ordered by the customer or requested by the ISP. I'm not sure what IDNet's policy is.

Well my changeover was scheduled for yesterday and it did go down and come back up at a slightly higher rate. Idnet page tells me I'm on Adsl2+ package also.
But yea it does seem like im still on adsl.

[Steve]

 

The other possibility is that for some reason they switched you to adsl2+ but profiled your line as adslmax (which they can) but I guess perhaps nothing has happened at all.

[Ray]

 

[esh]

I would probably drop IDNet an email. They kindly explained to me that my router didn't support ADSL2+ at the time, which is why I upgraded. So if you can't support it for some reason, they should be able to tell you why, otherwise there might need to be a switch flicked somewhere at the exchange even if your line supports it now.

[Rik]

Welcome to the forum, Zipp.

My best guess would be that BT haven't properly configured your circuit, either phone support or drop them an email, but they won't be able to do anything for you till Monday morning, unfortunately. It is possible that the router is the issue, so it's worth checking you have the latest firmware. (Incidentally, always try and avoid Friday activation dates with BT as, if anything does go wrong, you're stuck with it till Monday!).

[MisterW]

Not being an Idnet customer I'm not sure how they go about provisioning transfers from 20CN to 21CN but

IP Profile for your line is - 7114 Kbps

That is a new style 88.2% profile , ONLY used on 21CN.
My guess is the you've been transferred to 21CN but provisioned on ADSL1, hence your speeds haven't changed.

AFAIK the 448kbps upstream indicates it's still ADSL (not ADSL2/2+).

Nope, its quite possible to provision an upstream cap of 448k on ADSL2+.

Idnet page tells me I'm on Adsl2+ package also.

I'd guess that actually means you're on a 21CN connection. There is a lot of confusion regarding 21CN and ADSL2+. ADSL2+ means its 21CN but 21CN doesn't necessarily mean it's ADSL2+. It's possible to provision 21CN on ADSL1 which is more or less the same as the old 20CN ADSLMAX.
As others have said, you need to contact support to establish what's happened.

[zipp37]

Apparently I am on adsl2+ and sadly my line wont allow for any improvement. Thx all for the help/advice.

[Rik]

  Thanks for letting us know.

[Steve]

Thanks , however can you recall your adsl downstream sync and margin. Just that I notice the downstream margin is sitting at 12 on adsl2+ and the downstream attenuation of 35 would ideally give a you much higher sync on adsl2+ of 10-11k.

[MisterW]

Apparently I am on adsl2+ and sadly my line wont allow for any improvement. Thx all for the help/advice.

Sorry, I'm not convinced, that sync of 8064 is suspicious, its the maximum interleaved sync on ADSL1 and as Steve says your downstream margin is raised. That could be either because your line is noisy OR more likely your speed is capped beacuse its restricted to ADLS1 and hence there is more headroom for the SNR.
Does the DGN2000 give the ADSL mode anywhere , it'll be something like G.DMT or G.992.x
Does this display give any more info http://192.168.0.1/RST_stattbl.htm ?

With an attenuation of 35db you should be capable of much higher speeds on ADSL2+.
 

[Steve]

Certainly it used to be the case that if the line struggled on adsl2+ it took a while before being re-profiled back to adsl.

[MisterW]

I didn't think it would ever automatically go back to ADSL1. If it struggles on ADSL2+(G.992.5) it will fall back to ADSL2(G.992.3) automatically but AFAIK to go back to ADSL1(G.992.1) needs a manual reprovision order to BTw.

[Steve]

Sorry I wasn't clear, we used to see the instability and banded profile imposition prior to the decision to re profile back to adsl1. Have things changed I wonder is there now some other determinants of adls2+ suitability rather than trial and error.

[MisterW]

No, I don't believe anything has changed. There is however a tendancy when migrating from 20CN to 21CN to assess the line capability and decide on ADSL2+ or ADSL1 based on whether the line is likely to benefit from ADSL2+. It's usually ADSL2+ if the line alraedy synchs > 4M.

From the stats posted, both you(Steve) and I believe zipp's line is more than capable of higher speeds.
I'm still convinced that zipp's line is ADSL1 and that someone in support is confused with the potential difference between ADSL2+ and 21CN, I've seen it all too often with other ISP's support but have, obviously, no experience with IDNet support. I've also seen occasions when BTw's systems have the wrong info and say the line is ADSL2+ when its actually ADSL1!.

If we can get the actual ADSL mode from the router that will be the definitive answer...

[zipp37]

Just had a call from a nice chap at idnet! Apparentley it was set to adsl and now he has changed this and I should see improvement overnight.
Thanks all once again.

[Steve]

Let us know how it performs on adsl2+

[MisterW]

and I should see improvement overnight

That's good news, post your routers stats again please, once the change has happened.

[Rik]

BT did misconfigure the circuit and will correct it overnight. 

[psp83]

Good old BT!

[Rik]

Some say that, others know them. 

[Steve]

BT did misconfigure the circuit and will correct it overnight. 

I guess adsl is the default profile unless the customer asks the ISP for the switch to adsl2+

[Rik]

Or BT screwed up.

[MisterW]

No comment

[psp83]

Or BT screwed up.

That's every day work to BT.

I would love to know how many mistakes that company makes in a week.

[MisterW]

So would BT

You may not have a connection in the morning 

[psp83]

The salary of each worker is based on screw ups, the more you make the better pay

[MisterW]

@zipp37, Any news ?
or do we take it from the silence that BT messed up again and psp83 was right

[Lona]

Or BT screwed up.

You can say that again, Rik. Look at the cockup BT made of my upgrade.  I can't say I see a difference. Speeds are just the same as adsl.

[zipp37]

@zipp37, Any news ?

Supposed to be reconfiguring it today but its getting late now, I'm not hopeful.

[Gary]

You can say that again, Rik. Look at the cockup BT made of my upgrade.  I can't say I see a difference. Speeds are just the same as adsl.

That all depends on the quality of your line, Lona. I went from a  adsl max 8128 to a adsl2+ 14215 sync with similar specs to Zipp37 and that has held, I'm not far from the green box though and my adsl line even though it was not interleaved had a lot of headroom snr wise.

[zipp37]

Latest news is that apparently there is a problem at my exchange and if they switch me to Adsl+2 atm I'd lose speeds rather than gain. They need to change a card or something after that i can be reconfigured. No eta on that though..

[Rik]

I gather that BT hope to replace the faulty card in a day or two.

[MisterW]

Sounds a bit like b******t to me. I'd be surprised if they knew the card wouldn't handle adsl2+ properly until they actually tried changing the line over. Unless of course they have already tried changing other lines on the same card and discovered a problem. Didn't think that BT had that good a system to detect common problems though

[Rik]

Cynic. 

[psp83]

After today's issue with my line upgrade to FTTC, BT probly can't find the exchange 

[Rik]

You mean they ever could? 

[zipp37]

Almost a week since i should have been switched. No clue when it's likely to occur! Definetely growing a  dislike for BT...

[Rik]

Welcome to the club.

[Lona]

That all depends on the quality of your line, Lona. I went from a  adsl max 8128 to a adsl2+ 14215 sync with similar specs to Zipp37 and that has held, I'm not far from the green box though and my adsl line even though it was not interleaved had a lot of headroom snr wise.

I don't know what a green box is let alone know where it is.

[zipp37]

Latest news is that there are still problems at my exchange which will be reviewed again on monday. I have no idea what this means does anyone else?

[Technical Ben]

Sounds like there is equipment problems at the exchange. Good news is, it's being looked into. But it may take some time to get an engineer to the site and parts ordered.

[MisterW]

<cynicmode>BT are stalling, hoping it will all go away!</cynicmode>

[zipp37]

6 days later and still waiting... Guess they don't believe in keeping customers informed at BT

[zipp37]

Apparently there is no capacity at the exchange for me to be switched to adsl2+.  So either people need to cancel or enough need to apply for the exchange to be upgraded!

[MisterW]

Again...

Sounds a bit like b******t to me.

I thought we'd established that you'd already been transferred to 21CN.

IP Profile for your line is - 7114 Kbps

That is a 88.2% IP Profile, ONLY used on 21CN.
AFAIK there is no reason why exchange capacity should be involved in changing a 21CN line from ADSL1 to ADSL2+.
Anyone else know differently ?

[zipp37]

Makes me wonder if I'd have all this trouble if my isp was BT itself?

[Simon]

No, more. 

[Technical Ben]

Yes you would. Worse, you'd not get told anything at all. You'd call, and what answer would you get? "Reset your hub"? (I've been there with O2, not sure if BT are the same, but I'd assume so.)

[zipp37]

It seems like the switch finally got turned on

Router: Netgear DGN2200
connection speed:  downstream 12278 kbps, Upstream 440 kbps
line attenuation: downstream 38.0 db, upstream 15.4 db
noise margin: downstream 6.2 db, upstream 26.8 db


Speedtester results: Download speedachieved during the test was - 8168 Kbps
                            For your connection, the acceptable range of speeds is 4000-21000 Kbps.
                            Additional Information: Your DSL Connection Rate :12278 Kbps(DOWN-STREAM), 440 Kbps(UP-STREAM)
                            IP Profile for your line is - 10832 Kbps

                            Upload speed achieved during the test was - 364 Kbps
                            Additional Information: Upstream Rate IP profile on your line is - 440 Kbps

Curious why upload is only 440 and why the max speed during test was only 8168? Is this because the line needs to resync?

[Steve]

Throughput is not too far from IP profile, I think you need to check at various times of the day as congestion may be playing apart. The upstream sync I would speak to support, they may be able to tell you how and why your line was configured in that fashion. It maybe to achieve the downstream sync they've had to back off on the upstream.

It's progress though.

[MisterW]

Curious why upload is only 440

I would guess you've got a capped upstream profile. Unless you do a lot of uploading I would stick with that, as uncapping the upstream can sometimes reduce the downstream.
Steve is right on the speed, its not far from your profile and I'd look at it at various times.

[zipp37]

Router: Netgear DGN2200
connection speed:  downstream 9296 kbps, Upstream 444 kbps
line attenuation: downstream 38.0 db, upstream 15.5 db
noise margin: downstream 12.3 db, upstream 26.5 db

Every day at 12.50pm my modem resyncs the connection speed drops and the noise margin rises!
Anyone know why this is? Everything seemed stable otherwise.

[Steve]

If it's the same time everyday it would be worth looking for some electrical equipment in the house that turned off/on at that time.
