Hi,
I've just renewed my contract with BT and have been moved to the up to 16mb ADSL2 product, I always had a rock steady full 8mb connection (for 5 years until today), my Hub now reports G.992.5 annex A which I believe is ADSL2.
My speeds are now way below what I had before - only about 3 meg or so.
I know there is a 10 day training period, but I've only read about the speeds going down and not up during that time !
Can I expect my speeds to increase during the 10 days or get even worse ?
I presume I cannot contact BT until the 10 days are up ?
In case it helps my stats from the hub are:

The speeds might go up, but usually with BT the DLM works by starting off fast and then slowing down.
Lots of spare noise margin, well beyond any target margins. I would do a reboot of the router in another hour or so and grab the router stats as soon as they are available. To get a better idea of what target they are using.
No reason why the line should not run well beyond 8 Meg based on the stats shown.

29dB of margin is why!
Hopefully that will come down rapidly unless there are noise spikes occurring on your line.
Wait a while longer and power off the modem and fully disconnect from the line. Wait for a few minutes (3 minimum, 10 or more to be safe) to allow the DSLAM to forget. Power up the modem until it is fully booted and then connect to the line. Do it just once as several in succession can suggest to the DLM there is a problem.
Check stats and report back.
Might also be worth getting Router Stats Lite running to see how/when any re-syncs and changes occur.

Sit and wait unfortunately. BT will not touch it until the 10 days is up unless you can persuade them it is a fault.
Get Router Stats Lite running and monitor the sync and SNR. If you have a BT Hub you will need the specific HH version though.

I'm pretty sure it must be a fault as it has worked perfectly for 5 years and the day they change it to ADSL2 it halves my speed 
The 10 day wait is a pain, but maybe it will correct itself.
|
|
|
As I say, get RSL running and store the plots. Run some TBB and BT speed tests and log the results so you have everything ready for day10, if you need it.

I'd rather not get into all that, basically BT have signed me up for another year and effectively halved my speeds when they said I would get almost double, not very happy at all - also I have BT Vision, not sure if that will carry on working if my speeds drop any lower.
Everything was fine as it was, really beginning to wish I'd stayed as I was.
Thanks for your help though, its appreciated, I spoke to the Indian call centre and he really didn't seem to understand what I was talking about, didn't even seem to know what ADSL2 was !
|
|
|
Hmm weirder and weirder - visiting http://www.bt.com/help/servicestatus and putting in my phone number gives a broadband fault on my line that was reported on 15 April, which was the day I renewed my contract with BT(????). - it says the fault is on BT Retail Servers.
|
|
|
I fully understand your "pain", particularly when you get put through to some non-understanding Call-Centre Operator.
Can I suggest that you contact BT via:- http://bt.custhelp.com/app/contact_email/c/4950
This will get you through to a more "knowledgeable" set of contacts!
|
|
|
|
Many thanks for that, I have contacted them using that form.
|
|
|
I got moved to ADSL2 a while back (?3 yrs) with promises of a faster and more reliable connection. It was all over the place for months, dropping out several times a day and often much slower than the previous 1Mb/s. After a while (many months) it seemed to get more stable and now stays up for several weeks at a go (sometimes, sometimes a few hours) but the speed is just the same as it was before. Totally pointless exercise if you ask me.
2Mb/s? Not in my lifetime! (Nearly true Dec 2011)
|
|
|
More than likely that I am teaching you to suck eggs, but, could you post the stats again when plugged into the test socket of the NTE, all else disconnected.
2db more attenuation than my line, which happily gave 18 meg sync when on ADSL2. That 29db snr is the indication that summat's amiss/the line can go faster.
|
|
|
There is clearly a fault somewhere, even if it is just a software setting somewhere in the system. On that attenuation you should be connecting at between 17Mbps and 19Mbps. You need to try to get past the 10-day waiting period barrier and get someone to take action now, as once the fault is fixed the 10 days will have to be re-initialised and run again. The results it is gathering are junk.
As a point of information,  , the standard (ADSLx) connections in this country are ADSL and ADSL2+. ADSL2 is set only occasionally, but can occur when ADSL2+ is set and there are disturbances on the line.
G.992.1 = G.DMT = up to 8Mbps = ADSL Max.
G.992.3 = ADSL2.
G.992.5 = ADSL2+.
That might sound pedantic, but it could matter. If you talk to support people you will confuse them by talking about ADSL2 when that isn't what you are on. Though in the case of the person you spoke to not knowing what ADSL2 was I doubt if they would know what ADSL2+ is either.

That is a high SNRM when you get that to go down the speed should return... the mods should be able to help (that is who you contacted, they normally respond within 3 working days).

Thanks, I didn't know it was the mods I contacted (it was a BT branded page given to me earlier in this thread - http://bt.custhelp.com/app/contact_email/c/4950).

Yes, I doubt "mod" is the correct word or even abbrev. It's just a specific BT Contact Us form.

Have you tried a couple of Factory resets of the HH? APparently that cures a lot of things.

I've had no reply to the form I filled out from BT yet, but I guess 3 days aren't up yet.
This 'renewal' is a nightmare, I'll probably lose BT Vision next.

Uptime: 0 days, 3:14:46 Why has your connection got this uptime?
|
|
|
|
No idea, I leave the hub on all the time, I presume it disconnected at some point.
|
|
|
|
That will be the problem. The constant disconnections will cause DLM to put you on a banded profile.
|
|
|
|
It's weird that the hub worked perfectly for 5+ years and the day they change me to adsl2+ it's possibly failing, I have a homehub 1 - is it compatible with ADSL2+ ?
|
|
|
Exactly the reason I suggested running Router Stats Lite - you can see what the connection is doing.

Get it to track Downstream Sync speed and SNR at 10 second intervals (if possible) or 30 seconds if that fails. Put teh graphs on an image hosting site and post links.

Keep it running all day at the shortest sampling interval that you can. What happened at 10:46 or was that when you started it running?
The SNR graph seems a little odd being FLAT ! I would expect to see some minute by minute changes. This is an old one of mine showing both Down (Rx) and Up (Tx) figures.
SNR
It demonstrates how the noise level changes continually and the gradual changes over a day on the downstream.

I started it running at 10:46.
I'll keep it running all day and post the graphs as it generates them later.
Its set to every 10 seconds..
|
|
|
|
|
|
|
|
|
|
|
Not much point in posting anymore graphs, its pretty much the same, noise margin either 30.5 or 31 and connection steady at around 2 meg.
I haven't heard back from anyone at BT/Mods yet regarding the form I filled out last Thursday.
Hopefully I'll hear soon.

Try sending another comment to them. There is an obvious fault and as your SNR is way up and stable, something is wrong or needs resetting.

Not necessarily! Many routers report 0dB power down on BTw connections.

Your noise margin was quite (not massively) flappy and up and down. It's probably just the router, you often see this on NETGEAR routers? Were you using one of them?
One of my lines never varied between between 0.1db whereas another could change +-4db.
Looking at the line with a complete flat SNR is normal on plenty of lines. It probably goes down a little overnight.
It just means your line has more noise / your router is reporting more.

Having just checked apparently it;s a firmware bug that misreports - my bad

Thanks guys, I think at this point all I can do is wait for the mods to reply to my form, tomorrow it will be a week since I renewed (and a week since I first contacted the 'mods') and BT 'upgraded' my account, my router just rebooted but everything is still the same
I really wish I had stayed as I was, everything worked fine before this 'upgrade'
|
|
|
I've been contacted by BT
I'll you let you know how things go.
|

|

BT Wholesale have run tests and think there is a fault in the exchange which is going to be looked at on Friday/Saturday, with follow up call's from BT on both Saturday & Monday to see where we are.
|
|
|
|
Well I'm not happy at all, after being told the exchange would be looked at by close of play yesterday, and waiting in for a phone call this morning I'm now told that BT Wholesale is 'very busy' and now cannot even look at the problem ih the exchange until next Thursday (2nd May !!!)
The lady on the phone was very apologetic but I really think this is unacceptable, add to this fact that BT Vision was 'upgraded' this week and has left me a long paying member with a now inferior box (removal of 1080i because my box is 'too old' & non working ESPN) and I feel that I've been badly let down.
How on earth can BT be too busy to visit their own exchange ???
I'm extremely angry and disapointed.

Maybe the job did get done yesterday as expected? It would be interesting to know what your own router reports now.
Fifteen error seconds in under ten minutes doesn't look healthy to me.

That settles that question then. Rather emphatically!
Have you tried a factory reset on the Home Hub? Possibly a couple. That seems to cure all sorts of HH problems.
If it doesn't, tell them the hub is the issue, and how you know, and you need a replacement.

I have rung the team that was helping me and told them, I was told I would be called back, but haven't heard anything yet.
I've reset the hub but it makes no difference.
It seems that the original hub doesn't handle adsl2+ or I just have a faulty one, its strange that it worked perfectly with adslmax for 6 years though !
|
|
|
Sounds more like it just doesn't handle ADSL2+.
Can you set it to G.DMT or G.992.1 in the GUI? That should get you back to your ADSL Max speeds until you get a replacement.

Its a BT home hub, the original white one (with the place for the phone).

It won't say ADSL Max. You are looking for the ones I gave. Possibly labelled Mode.

Sounds more like it just doesn't handle ADSL2+. It wouldn't say this then: Modulation: G.992.5 annex A but it might not handle ADSL2+ properly or need a firmware update to do so.
EDIT: Rather remiss of BT to upgrade connection but not send out new router, knowing OP has original router for years running only on ADSL Max.

Something is obviously wrong with this particular Home Hub unit.
However, they all support ADSL2+. BT have a helpful list confirming this.

Thanks everyone, looking at that list - I have the home hub 1.0
Its running 6.2.6.h firmware, which seems to be the latest.

Hi Merly, did you get this problem solved? I upgraded my BT broadband to the same as you, just under a week ago, and I'm having a lot of problems.
Everything is running very slow, and videos take so long to load, then keep buffering.
I have never had this problem before, and I had been on the same basic package with BT for more years than I can remember.
I'm beginning to wonder if I have done the right thing. All I wanted was to be able to use it more than I could on 10gb.
I didn't realise anything would change like that. Is is a waste of time?????
