Exchange recently upgraded - no ADSL2+, speed decr...

I got an email on 18/04/2011 from '[email protected]' saying:
'Good news. We’re rolling out our faster broadband and we’ll be upgrading our network in your area on 21-Apr-11. This’ll make the things you do online quicker.
This happened and since then my broadband speed has decreased from being a constant 8128Kbps down and 448Kbps down to varying from 6Mbps to 8064Kbps and LOTS of retraining. Any realtime applications like Skype or BT Broadband Voice are just unusable due to the constant retraining.
I have been on this line since 01/10/2010 and it has always been 8128Kbps down and 448Kbps up and never deviated until the 'upgrade' on 21/04/2011.
I use a Cisco 877 router with IOS 15.1(2)T2 and have tried various ADSL firmware (4.0.17, 4.0.18, 4.0.195, 4.0.209 & 4.0.210) all have given the same behaviour. I have now reverted back to the 4.0.17 firmware as this supposedly has fixes for UK ADSL2+:
ADSL firmware version 4.0.17 for UK annex M support only. Compatible with Huawei MA5300 DSLAM, EADB line card
I have spoken to BT and they say this is normal for the 10-day stabilsation period following the upgrade. I was hoping following the upgrade that ADSL2+ would be enabled and due to the maximum 8128Kbps I was getting prior to the upgrade I would get a faster connection. So far its been bad news.
I am likely to get ADSL2+ and will it stabilise at some point?

Modulation is ITU G.992.1 (G.DMT) Annex A according to the router stats. I have tried forcing ADSL2+ on the router but it fails to train.
The router is connected to the BT Master socket using the BT ADSL v1.0 faceplate that I took from the previous line when we moved.

What To Expect As Exchange Is Upgraded To ADSL2+

Hi
Currently I have ADSL Max with 8128/448 down/up line speeds. I get around 7 meg actual download speed. I use a TP-Link ADSL2+ modem router instead of the HomeHub 2 because the wireless network in the HomeHub kept crashing all the time (bug in firmware).
Yesterday I typed my phone number into the checker to see what line speed I should be getting these days and it gave me the ADSL2+ figures saying I should get around 17 meg download.
Called BT support who confirmed my exchange has been upgraded. They moved my line onto another channel and said that the speed should increase within a few hours. It didn’t so I called again and was told that even though the exchange had been upgraded, it would take several weeks for all the subscriber lines to be moved over to the new equipment so I should be patient.
I’m presuming that when my line is moved, the electrical connection will be broken, I will lose broadband temporarily and my router will automatically reconnect at the higher speed once the line is connected to the new equipment. Is that right or should I periodically reboot my router over the next week or so?
Is there anything else I should do in order to get ADSL2+ as soon as possible?
Thanks

Go to Solution.

Just in case it helps any others in future, I thought I would post what actually happened to me so others can know what to expect.
1. The offshore support people haven't got a clue. They gave me false information.
2. About 10 days ago I had an internet chat with another support guy (seemed like he was based in UK). He said I would have to phone in after 10/12/11 and sign up to a new contract in order to get the speed bump. This turned out to be false information too.
3. Earlier this week I received an email from BT telling me that my line would be upgraded today and to expect exactly what john46 told me on this thread. That's exactly what happened half an hour ago.
I now have about 16mbps download speed and the whole internet experience is a lot snappier.
I do however wish that BT could get its act together. It is obvious that the support people haven't been properly briefed.
Happy days

Slow speed/high SNR margin after upgrade to ADSL2+...

I have an issue with slow speed that I am suspecting is caused by a high SNR margin (about 12dB) which has come about (I believe) due to the fact that my router was repeatedly reset during the first few days of the upgraded service. The exchange was upgraded to ADSL2+ on 3rd January.
I have a US Robotics 9108 which has worked fine for nearly six years. I was getting around 8Mbps before the upgrade which isn't far off the theoretical maximum.
There was a problem with my router and I only found it to be my router at fault over the last few days. Upgrading its firmware has cured the problem which was that requests weren't being fulfilled once connection had been established, (seemingly particularly when this was ADSL2+ or ADSL2 mode). Consequently, I reset my router in these instances and I believe that this will have been interpretted by the exchange as being due to line noise. In general, I disabled ADSL2 and 2+ modes on my router to force it back to G.DMT and it usually worked fine (albeit slow sync rate relative to that I had before 3rd January).
During fault conditions, the connection synced OK. I recently borrowed a router and tried it and it immediately connected faster than mine had done previously and I could access the web without issue. This confirmed that my US Robotics was at fault, and after downloading its latest firmware, it fixed the problem.
There is no bell wire as there are no hard wired extensions from the master socket. I use a single filter which plugs directly into the master socket (i.e. no extension lead to the filter).
I was using a BT filter (MF50) I got in 2004 when I first got broadband. This came with a Voyager 100 modem and is a rebranded YCL one. I have since replaced this with a Z350-UK which I have borrowed. The US Robotics didn't come with any filters.
With the BT filter, caller display does not work at all when the router is connected in ADSL2 mode. In G.DMT mode the problem with caller display was intermittent. The Z350-UK has rectified the problem with caller display not working when in ADSL2 mode. I have ordered a Pressac Interstitial VDSL Faceplate as a perminant solution.
Do I need to contact the support helpline to get this fixed? Or will the SNR margin drop over time? As I say, I got around 8Mbps before the upgrade.
I am presently connected in 2+ mode and stats are:
SNR margin (dB):
12.8

Exchange and Account Upgraded to ADSL2+ - Stuck at...

Okay, so toward the end of July my exchange was upgraded to ADSL2+. I requested my account be upgraded which I am assured has been done, along with the associated profile change, with an estimated speed of 17Mb.
However, my Draytek Vigor 120 ADSL2+ modem is still syncing at 8128.
I have tried manually setting the connection to:
VPI: 0
VCI: 38
Enscap: VC Mux
Protocol: PPPoA
Modulation: ADSL2+(G.992.5)
When I do this, the modem just sits at 'hand shaking' but if I set modulation to multimode then it connects at 8128.
I have tried switching to the master socket and tried a different modem/router, but the sync never changes. I don't have a home hub as I have always had my own equipment.
I am awaiting an engineer visit on Saturday, but I thought I'd check here first, in case there is anything else I can try, especially since there is the usual; BT's fault it's free, my fault £99.
Any thoughts would be gratefully received, thanks in advance.

I suggest you contact the forum mods they should be able to get your problem sorted for you this is a link to them

My exchange has recently been upgraded to ADSL2 - ...

Hello,
I signed up for BT Total Broadband just over a year ago and I was connected at 8,128 Kbps on ADSL Max because that was the best my exchange offered. However, according to Sam Knows, my exchange has recently been upgraded to ADSL2. I tried running the line speed test for my phone number on the BT Broadband signup page and it now estimates my line speed would be 19Mb. I tried restarting my home hub but it just reconnected at 8,128 Kbps with G.992.1 Annex A. Is there anything I need to do to get the faster speed? Or is it just a case of waiting and it will happen automatically at some point?
I'm quite happy with my connection but obviously the faster speed would be great
Thanks for any help!
John

Hi once an exchange goes live it can take from a few days to several months for all lines to be moved over to the new ADSL 2+ equipment you do not need to do anything apart from wait BT will send out an email when your line is due to be moved across

Exchange Upgraded however my Speed has not increas...

Hi, I have recently learned that my exchange has been upgraded and is capable of speeds up to 17 Mbps over ADSL2+
To make sure I tested my phone number on the bt wholesales site. However I am currently stuck at 8.0 Mbps and the modulation is still on ITU-T G.992.1
I understand I may have to contact BT to sort this out. Is this correct? Or should I wait? I read around on the forums that I will be much better to contact the Mods than to call them. If so then i will probably use this post as reference for that.
Thanks in advance

I will follow with the btspeedtester results shortly, having some issues with timing out. Though from what I have seen it shows my current download speed but does not indicate that I can/should get ADSL2+ speeds. But from the wholesale checker it tells me my line supports ADSL2+
Wholesale output:
For Telephone Number 01946xxxxxx on Exchange EGREMONT
Your exchange is ADSL enabled, and our initial test on your line indicates that your line should be able to have an ADSL broadband service that provides a fixed line speed up to 2Mbps.
Our test also indicates that your line currently supports an estimated ADSL Max broadband line speed of 8Mbps; typically the line speed would range between 7Mbps and 8Mbps.
Our test also indicates that your line currently supports an estimated ADSL2+ broadband line speed of 17Mbps; typically the line speed would range between 10Mbps and 19.5Mbps. Our test also indicates that your line could support an estimated ADSL 2+ Annex-M broadband upstream line speed of 1.5Mbps and downstream line speed of 17Mbps; typically the downstream speed would range between 10Mbps and 19.5Mbps.
The actual stable line speed supportable will be determined during the first 10 days of use. This speed may change over time, to ensure line stability is maintained.
If you decide to place an order, a further test will be performed to confirm if your line is suitable for the service you wish to purchase.
Thank you for your interest.
Please note that postcode and address check results are indicative only. Most accurate results can be obtained from a telephone number check.Note: If you already have a Broadband service enabled on this line and you want to switch service providers, you will need to contact both your current provider and your new provider to get your service changed over new and existing service provider to have this service transferred.
Also provision of some services may not be allowed due to product withdrawal, please contact your service provider for further details.

Upgrading to better speeds after exchange upgraded...

Hey,
My exchange has been marked as on the 21NC for probably close to a year now however I never got a speed boost after the upgrade. I figured my download speed might not of changed because of the SNR but my upload speed should of? So I assume the speed is still capped at the "upto 8Mb"?

Recently upgraded my macbook pro 13 late 2009 to an ssd but only getting a quarter of the speed

Hi, i recently upgraded my macbook pro 13 inch to a OCZ VERTEX 3 240gb ssd. The drive is supposed to be able to have write speeds of 500mb/s and read speeds of up to 550 mb/s but when i run a speed test on the disk im only getting a max write speed of around 105 mb/s, and read speed of 137mb/s ish, now the negotiated speed is only 1.5gb/s I have trim enabled, and i have tried changing the link speed but with no luck. The drive is rated for 6gb/s also. The drive is not in the hard drive bay because my hard drive cable is broken, i have it in the optical bay right now, could someone please help me or tell me how to make the drive at least go up to sata 3 speeds,

The 2009 MBPs were built with a very cheaply made HDD to LB cable. So I bet if you change that cable you will see more speed from that SSD.

I am using several Macs running Yosemite. I was recently “upgraded” to Xfinity’s new cable modem which can support both 2.5Ghz and 5Ghz networks at the same time. Actually I can connect to the internet over both with a satisfactory bump in speed for the Ghz. However when I connect to the 5Ghz the Time capsule disappears from the Airport Utility and claims to be Not Found. Is there something I have done wrong or just a Yosemite Teething Problem

First restart your mac and try again.
It could be
that the router and the TC are interfering wirelessly with each other.
You can check this by pressing the option key while clicking on the wireless icon on your screen
Open Wireless Diagnostics
enter your user password
Press CMD 4 then Scan
You will see all the wireless channels being used in your location and you can check if they are on the same channel
Make the SSID for the TC simple like MyTC
Set 5Ghz to auto
Update the TC
Try again

I recently upgraded my internet service with Comcast for faster internet. When I use an ethernet connection I get 50 MB download speed....when I use the wireless connection I get 10-20 MB speed. I have an airport extreme...3-4 years old. Why is the speed so different and are there settings I can change to increase the wireless speed?

If your supposed to be getting 20 Mb/s down via your ISP and both Mac's are not getting that on the SpeedTest, then obviously your router appears to be the cause.
Connect one Mac directly to the ISP's modem, power off/wait 30 seconds/then power on, then power on the Mac. The ISP will connect directly to the Mac, then run a SpeedTest.
Then repeat the same for the other Mac. If both Mac's have a problem then it's possibly the ISP, the modem, your lines to them or on your property, or both Mac's are messed up.
You'll have to keep searching for the cause. Call your ISP and ask then to run a test to see if your getting your 20 Mb/s to your modem, that should clear part of the problem.
Diagnosing network issues

Recent upgrade from 2 to 4 GB remarkably speeded up my Mac. However, in last two weeks it has reverted to extremely slow ops, so bad I can hardly get G-mail to open or even navigate within Apple programs. Anyone know what's happening here?

My mac was barely creeping along when community evaluation suggested my RAM was maxed out so I upgraded. Operation speed increased dramatically for about 2-3 weeks and all of a sudden it is back to a crawl. I can hardly open G-mail and also have problems navigating between Apple programs like opening numbers, etc. I checked ookla speed tests and am operating around 25 + mbs for downloads and about 10 for uploads. G-mail error notices state slow problem is due to flaky connectivity. Nothing new has been added to the computer to account for this slow response. Any suggestions for this performance change?

1. This procedure is a diagnostic test. It changes nothing, for better or worse, and therefore will not, in itself, solve the problem. But with the aid of the test results, the solution may take a few minutes, instead of hours or days.
Don't be put off by the complexity of these instructions. The process is much less complicated than the description. You do harder tasks with the computer all the time.
2. If you don't already have a current backup, back up all data before doing anything else. The backup is necessary on general principle, not because of anything in the test procedure. Backup is always a must, and when you're having any kind of trouble with the computer, you may be at higher than usual risk of losing data, whether you follow these instructions or not.
There are ways to back up a computer that isn't fully functional. Ask if you need guidance.
3. Below are instructions to run a UNIX shell script, a type of program. As I wrote above, it changes nothing. It doesn't send or receive any data on the network. All it does is to generate a human-readable report on the state of the computer. That report goes nowhere unless you choose to share it. If you prefer, you can act on it yourself without disclosing the contents to me or anyone else.
You should be wondering whether you can believe me, and whether it's safe to run a program at the behest of a stranger. In general, no, it's not safe and I don't encourage it.
In this case, however, there are a couple of ways for you to decide whether the program is safe without having to trust me. First, you can read it. Unlike an application that you download and click to run, it's transparent, so anyone with the necessary skill can verify what it does.
You may not be able to understand the script yourself. But variations of it have been posted on this website thousands of times over a period of years. The site is hosted by Apple, which does not allow it to be used to distribute harmful software. Any one of the millions of registered users could have read the script and raised the alarm if it was harmful. Then I would not be here now and you would not be reading this message.
Nevertheless, if you can't satisfy yourself that these instructions are safe, don't follow them. Ask for other options.
4. Here's a summary of what you need to do, if you choose to proceed:
☞ Copy a line of text in this window to the Clipboard.
☞ Paste into the window of another application.
☞ Wait for the test to run. It usually takes a few minutes.
☞ Paste the results, which will have been copied automatically, back into a reply on this page.
The sequence is: copy, paste, wait, paste again. You don't need to copy a second time. Details follow.
5. You may have started the computer in "safe" mode. Preferably, these steps should be taken in “normal” mode, under the conditions in which the problem is reproduced. If the system is now in safe mode and works well enough in normal mode to run the test, restart as usual. If you can only test in safe mode, do that.
6. If you have more than one user, and the one affected by the problem is not an administrator, then please run the test twice: once while logged in as the affected user, and once as an administrator. The results may be different. The user that is created automatically on a new computer when you start it for the first time is an administrator. If you can't log in as an administrator, test as the affected user. Most personal Macs have only one user, and in that case this section doesn’t apply. Don't log in as root.
7. The script is a single long line, all of which must be selected. You can accomplish this easily by triple-clicking anywhere in the line. The whole line will highlight, though you may not see all of it in the browser window, and you can then copy it.

Copy the selected text to the Clipboard by pressing the key combination command-C.
8. Launch the built-in Terminal application in any of the following ways:
☞ Enter the first few letters of its name into a Spotlight search. Select it in the results (it should be at the top.)
☞ In the Finder, select Go ▹ Utilities from the menu bar, or press the key combination shift-command-U. The application is in the folder that opens.
☞ Open LaunchPad and start typing the name.
Click anywhere in the Terminal window and paste by pressing command-V. The text you pasted should vanish immediately. If it doesn't, press the return key.
9. If you see an error message in the Terminal window such as "Syntax error" or "Event not found," enter
exec bash
and press return. Then paste the script again.
10. If you're logged in as an administrator, you'll be prompted for your login password. Nothing will be displayed when you type it. You will not see the usual dots in place of typed characters. Make sure caps lock is off. Type carefully and then press return. You may get a one-time warning to be careful. If you make three failed attempts to enter the password, the test will run anyway, but it will produce less information. In most cases, the difference is not important. If you don't know the password, or if you prefer not to enter it, press the key combination control-C or just press return three times at the password prompt. Again, the script will still run.
If you're not logged in as an administrator, you won't be prompted for a password. The test will still run. It just won't do anything that requires administrator privileges.
11. The test may take a few minutes to run, depending on how many files you have and the speed of the computer. A computer that's abnormally slow may take longer to run the test. While it's running, there will be a series of messages in the Terminal window like this:
Part 1 of 8 done at … sec
Part 8 of 8 done at … sec
The messages won't be spaced equally apart in time, but they give a rough indication of progress. The total number of parts may be different from what's shown here.
Wait for the final message

Very slow ADSL2+ speed in ROMSEY

hi I am in Romsey Vic over the past month I have noticed my ADSL2 speed have dropped from over 11Mbps down to below 1.0Mbps. I am less than 2 KM from the exchange. i call Bigpond on Sunday and spoke to them for 30 minutes, during this time the speed did improved, 30 minutes later I was back to the slow speeds. Yesterday I got the new Telstra GateWay Max TG799 modem and connected it and still having the same slow speeds. Last night around 8pm the speed return back to 11.0Mbps. This morning it was back down to approximately 1.0Mbps. I was told when I got the modem i should see faster speeds with the newer model, what a joke. Has anybody else experience the same problem in the Romsey area. Are Bigpond able to check the exchange and see what is using all the band width? I find that the mobile braodband is faster around 30Mbps in the area, and yet ADSL2 is around 1Mbps. Can anybody help, or is Bigpond forcing customer to go to Mobile for better speeds? I use abouit 50 -60GB per month, Thanks,John

It could simply be increased usage patterns. It may have been getting progressively worse over time, but only recently reached a level where you really start to notice it.
I'm with iiNet and since April my speeds have gone from 20Mbps normally, to as low as 2Mbps during peak periods. 1/10th of what my service is capable of supporting. This is due to peak congestion.
Telstra Wholesale, which are an entirely different business by law to Retail (who you deal with) would likely be able to see what exchanges have links that are congested/saturated. However Retail rely on them to make the decision on when and if to upgrade backhaul to these exchanges.
So if you don't yet appear on the backhaul relief as per the link I posted above there are no current plans to provide an upgrade to help out with the congestion.
The worst part is, depending on your location, changing providers may not even help

Upgraded to ADSL2 - what is ADSL2 DELT?

I signed up to ADSL2 and have read the forums about the 10 day training period. It was turned on sometime on the night of 28 December. I have been running a BTspeedtest daily in case any issues developed.
Day 1 was 30 December and the result looked promising

Given the downstream rate on day one I was expecting that the IP profile would catch up.

The downstream has held at 6656 kbs since as has the IP profile at 15000 kbs which to me seems odd. I would have expected the IP profile to have to catch up with the download speed.
I have a Zyxel P660 HW-T1 v2 router and have today noticed that it is in ADSL2 DELT mode. I don't know how long it has been in this mode. After a bit of googling led me to conclude a possible issue with the router due to this http://www.aaisp.net.uk/kb-broadband-zyxelp660hwt1v2.html . I have therefore tried the telnet change suggested and rebooted my router (I know this may mean having to restart at day 1 again, but given that things had settled down I felt that nothing ventured nothing gained). The router is still showing that it is in ADSL2 DELT at the rate of 6656kbs and I am therefore wandering what it is and whether something at the BT end of the operation is causing this.
Whilst posting I would welcome some comments on my noise margin seeing as my router is plugged into an extension via an ethernet cable - it is fairly impracticle to plug it into the master socket as I would have to run wirelessly which I know I could do but some speed loss is inevitable doing it this way.
Margins are:-
noise margin upstream: 8 db
output power downstream: 13 db
attenuation upstream: 11 db
noise margin downstream: 19 db
output power upstream: 11 db
attenuation downstream: 18 db
This 10 day training period is a real pain but I am happy to perservere with it as I feel that given the IP profiles I am acheiving I will end up with a speed that will be the envy of most - I would just like to get to the bottom of the ADSL2 DELT issue as I feel that a cap of 6656 kbs that it appears to be causing is not going to assist the overall training on the line.
Solved!
Go to Solution.

I would rather leave it until the 10 period is up before I start testing my router on the master socket. The reason is because the master socket is in the lounge and the router has several bright green lights that irritate my partner. It would also mean I would have to run my PC wirelessly which creates its own set of problems whenever I use my laptop.
If after the 10 days are up there has been no improvement then I will have to consider moving my router or see how much it would cost to get cat 5 cable to replace the phone line to the extension socket - that would eliminate the need to use the router in the master socket. Obviously either course would need a further 10 days to prove that it is either a router setting or something at BT's end.
As you have confirmed the second test and one I did yesterday which is below showed IP profiles inconsistant with 6656 speeds suggest that something is not quite right somewhere.

The Router shows System up time - thats all. It stays on 24/7 even if something has gone wrong at the BT exchange - happened once - the only way the counter can be reset is if you reboot it. As I have advised it was not rebooted until today and I have not seen any explanation for the strange IP profiles when compared with the speed.
These speed tests indicate that something was not quite right before today's reboot of the router - I will continue to monitor daily and review where things are in 10 days time unless anything else strange happens - I am not that concerned if I have a bit of noise on my extension - if my line accepts say 17.5mb but internal wiring strangles it to 10mb that will be still acceptable as I will know that there is something I can do about it. I had some difficulties when I upgraded to ADSL2 but removing the bell wire sorted that one and I was on a steady 7500 IP profile and receiving around 5-6MB speeds through the extension.
It just peeves me that you have to wait 10 days when the evidence is there that something is not quite right. It's like baking bread, if you can't see it rising in the oven you know that the end result is no going to be any good and I think the same applies in this case - if both IP profile and speeds were low then I could accept the wait, but not when the IP profile was there(and hopefully will return over the next couple of days).

Is it true ones been upgraded to ADSL2 it's not po...

Hi
The problem is some months ago I got BT to upgrade my broadband from ADSL MAX to ADSL2 not ADSL2+ thinking I might get better
speeds on my line but in the end all I got from ADSL2 is a hole **bleep** load of problems and no speed increase on download but
just a slight increase in upload speed.
When I was on ADSL MAX I was able to maintain a connection speed of 2.5MB and 3MB maxumum speed but ever since upgrading to
ADSL2 i`m barely even getting 2MB stable because of the **bleep** banding that you get with ADSL2.
During the time I upgraded my broadband to ADSL2, my line had around a 57 db line Line attenuation and
after the upgrade and
when I saw I was getting nothing but problems, BT tried changing my E pare from the green cabinets down to the exchange
thinking this could be causing me the problems which it wasn`t but did gave me a extra 1MB out of my connection giving me a
4MB capable line from the 3 MB maximum I use to have but even then I still can`t even get 2MB on ADSL2.
My line use to only have a sync rate of around 3700Kbps but now has a Line attenuation of 50-51 db with a maximum sync rate of
4800Kbps because of the E pair change.
I have told BT that my line stableness has gotten worse since moving to ADSL2 and if it is possible that could downgrade my
broadband back to ADSL MAX but according to them, ones i`m on ADSL2, it's just not possible to be switched back to ADSL MAX again.
I was wondering if this is correct or are they polling a fast one? and is there anything I can do to get them to downgrade me back
to ADSL MAX?
Thanks for responding.

I forgot to say in my original post that I have been experiencing quite frequent dropouts since the start of this year even when I was on ADSL MAX but I was still able to maintain at least 2.5 MB speeds but it seems I think the main problem is ADSL2 doesn`t like frequent dropouts at all and i've noticed even one bad dropout on ADSL2 is enough to kicking the banding system to drop my speed margins drastically.
As i`m receiving frequent dropouts, my connection is not staying connected long enough for the DLM banding on my line to further reduce to give me back more of my line speed.
At least on ADSL MAX it gave you 10 dropouts within one hour before I would lose speed.
There is a outgoing case between me and BT and my dropout problems now since some months but BT just can`t seem to find where the problem is and I think BT has now had enough and just keep fobbing me off saying the speed ADSL2 is giving me is the maximum supported speed i`ll get from my line which is a load of **bleep** as my line connects no problems at 4MB with a 6db noise margin though because of the stupid banding on ADSL2 and my frequent dropouts, my speed just goes way down to nothing.

Exchange recently upgraded - no ADSL2+, speed decr...
