Hi - first time post having just joined BT from another ISP after moving house (I'd heard some good things from friends so thought I'd give it a shot!).
When checking the BT wholesale site I get the following:
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 11.5Mbps; typically the line speed would range between 6.5Mbps and 15.5Mbps. Our test also indicates that your line could support an estimated ADSL 2+ Annex-M broadband upstream line speed of 1Mbps and downstream line speed of 11.5Mbps; typically the downstream speed would range between 6.5Mbps and 15.5Mbps.
Now I'm connected up using a new ADSL2+ supporting Netgear router - I've specified the following settings:
LLC Based Multiplexing
DSL Mode Auto
Transfer Mode ATM
I'm really noticing quite slow up and down bandwidth (relative to what I had previously).
I'm in a new flat and BT have installed a new connection. I'm ~900m from the exchange as the crow flies.
My router stats are:
Downstream Connection Speed - 8128 Kbps
Upstrream Connection Speed - 448 Kbps
My line noise / attenuation is 27db downstream and 14.5db upstream
When I test using the bt speedtester I get downstream rates of 6478Kbps
If I use something like speedtest.net I get ranges between 4549Kbps and 6557kbps down and 343Kbps to 369Kbps up.
From my point of view with the proximity to the exchange and the noise that is being reported I'd be expecting to synchronise to the exchange at higher rates and therefore get a better service.
Is there any way of checking that I've definately been provisioned an ADSL2+ connection rather than a ADSL Max? (the 8Mb synch to the exchange looks a bit suspicious)
Any ideas or help?

welcome to the forum
you are on adslmax with the speeds you quote - adsl2/2+ will show a modulation of 992.3/992.5 and not like yours 992.1.
check to see if your exchnage is 21CN enabled http://www.samknows.com/broadband/exchange_search

Thanks very much for the quick reply.
The exchange (ESDON) is indeed 21CN / ADSL2+ Enabled.
I tried to discuss with BT Tech Support and they were nice but they weren't really much help (other than offering me a paid service for somebody to come and have a look).
I don't have any way of checking the modulation - but you appear to know mine is 992.1 - were you able to work this out or are you assuming from the speeds?
Any recommendation on how to take this forward?
Really appreciate all/any guidance and assistance!

if you are using a hub then enter 192.168.1.254 into your browser and then navigate to adsl and you will see all the stats which are posted by others. you can post yours which will help. you should see from your connection speeds a modulation of 992.1 which is adslmax - 8128/448.
as you have just joined Bt you can first try to contact uk sales 08007830056 and complaine that your exchange is 21CN enabled but you are only on adslmax. if that does not work then post your stats and then contact the mods to get moved on to 21CN adsl2/2+ http://bt.custhelp.com/app/contact_email/c/4951
mods are uk based and can take up to 3 days to contact you but try sales first

Sadly not using a BT Hub.
Followed your guidance and spoke to sales, they see that the order was placed requesting ADSL2 ...
They suggested raising a grievance so I get a dedicated resource to look at this. Fingers crossed!
Thanks for your help!

if they won't help my suggestion to get a solution is to contact the mods as you will find that gives a better and more important faster solution.
which router are you using?
on 07-01-2012 15h10
so enter 192.168.0.1 should take you into the manager then I think something like router status and the at the bottom show connection details
on 07-01-2012 16h11
Yes, the router stats are pretty terse:
|Connection Speed||8128 kbps||448 kbps|
|Line Attenuation||27.5 db||14.5 db|
|Noise Margin||8.1 db||25.0 db|
I'll maybe see if there is a command line interface that I can use to get more info...
