Hello techies - I'm not so up with how it gets to the router and hope that someone could explain what's going on here.
Changed to Post Office Broadband from Newnet on 3rd July (already had PO homephone for 4 years and Newnet for 4 years). IP profile with Newnet 5.5Mbps dropped to 2.0Mbps on 3rd July when changed over to Post Office. Corresponding speed drop from over 5Meg to less than 2Meg.
BTW speed test:
Download speed 1.96Mbps
DSL Connection rate 6.05Mbps(Down) 0.45(Up)
IP Profile 2Mbps.
ThinkBroadband graph: I haven't worked out how to post this but it drops off a cliff! horizontal at 5Meg until 3rd July and drops, drops, drops.
Post office are adamant that no problem and my line is only capable of "stable" 2Meg! I will cancel the PO contract if necessary and change to someone else (who?), if I cannot make them see sense here.
I hope someone can provide me with some useful advice here or suggest what actions I could take.
thanks

Post your router stats so we can assess what your line is really capable of.
Also what exchange?

Thanks for your interest. I have a ZyXEL router supplied by PO. I'm not sure if this is what you want to see but in Diagnostics I found this:
relative capacity occupation: 54%
noise margin upstream: 20.0 db
output power downstream: 20.0 dbm
attenuation upstream: 24.0 db
followed by tone bits table
and then
relative capacity occupation: 121%
noise margin downstream: 6.0 db
output power upstream: 12.0 dbm
attenuation downstream: 47.0 db
also followed by tone bits table.
It may be relevant that yesterday morning when I spoke to PO they took me through the WAN tab and found the login identifier as the ZyXEL default which we then altered to my PO ID - he said I should see a change later. When I contacted PO late afternoon they were not interested in investigating further and said I was only going to get 2Mbs. I have had consistently 5Mbps for at least the last 9 months.
If the above isn't what you need from the router to advise me, then please let me know.
Many thanks for your time. I hope to hear from you.

Speedtest graph, right click to get link to the graph and post that.
Each graph has a unique name but vanish after a few days or weeks

The connection speeds from the same time as the stats are really needed but if earlier figures apply it looks like yes ip profile should be higher
Need to keep on at PO support, good luck
If your upstream is 448 kbps then old style adsl and ip profile may well fix itself in a few days. Maximum of five days

Thanks for the advice - current test is
http://www.thinkbroadband.com/speedtest/results.html...
However I don't know how to display the ThinkBroadband history graph that I have from early this year to current date which clearly shows the drop.
I also have BTW speedtest results which I don't know is helpful towards an interpretation.- these currently show speed 1.93Mbps, DSL connection rate 6.3Mbps (Down), 0.45Mbps (up), IP Profile 2Mbps
I may have problems with PO support who completely blanked me yesterday afternoon and said I wasn't going to get anything better! I think my only route is now to write to their complaints office and see if someone will look into this further. Newnet did have problems with early May where they asked me to turn off my router when not using the computer - which I'm informed was resolved by them and concerned only certain makes of router - it was not the line that was a problem.
Hopefully someone can make some sense of this for me so I can make the case.
Thanks again for the help

I'd wager that 2 meg is what the PO has asked BT Wholesale to provide for you.
Sadly, the PO as an ISP has a poor reputation for customer support, so getting this resolved may prove painful.
Good luck.

The speed test graph is nice to see, but you need to go and check what the connection speed for the upstream is showing as in the zyxel router, the number being 448 or something else is important to how we answer and suggest what may be the best course of action.
the rounded number of 0.45 from the BT speedtest is not accurate enough.

Thanks again Mr Saffron after stumbling around in the router I found on the Status page the ADSL Showtime stat as 6336/448. So can I deduce that this is the current reading of 6336 (Down) and 448(Up) and as you point out my line has been setup by PO to 2Meg?
If this is the case then its very naughty as I was told that my line, as with Newnet, would work by operating as fast as the line would allow (previous IP profile 5.5). I will put that to them and see what they say - I always have the option of cancelling and hopefully seeing what action I can take with consumer laws. I was reasonably happy with Newnet and other than the odd niggle only changed to rationalize billing ( I'm getting on a bit now). It makes a bit of a nonsense the PO telling me to wait for line training and then have the audacity to say its unstable!
If there is any other route that I could investigate following I would be grateful to hear.
Best regards.

When you speak your ISP support again ask for a SNR reset as a stuck 2MB profile can be a common fault on 20CN products.
If all is well you should get your profile changed within 24 - 48 hours, (be aware DLM restarts it's 10 day test after the reset has been requested)
Hope this helps.

The IP profile might still improve of its own accord, how many days since it was at 2 Meg? if more than five then it looks to be a good old fashioned stuck IP profile - rare these days.

It has now been 11 days at 2Meg! I had asked about a stuck profile but the last support staff I spoke to weren't interested in doing anything. Today I'll write to their complaints dept and if their response is negative cancel the line with them and suffer the consequences - and make sure as many people as possible are aware of what can happen.
Thanks again.

have you left the router off overnight once in case that wakes something up.

Yes I tried it last night and has made no difference - either the line is now "trained" at the lower level or the PO have set this up with some kind of cap - router still reads Rate 6336/448.
Wish I hadn't changed and had stuck with Newnet.

They cant cap ip profile only sync speeds

Thanks again - I am slowly learning a bit more. I've just got off the telephone with PO Support and after explaining carefully the situation a very helpful person looked at this closer and said it had been manually capped at the exchange. They have asked me to connect to the test socket and carry out speed tests for 24hr and then they will look at getting an Engineer to investigate - hopefully I'll sign off here in the not too distant future with a resolution.

More FUD, the exchange houses the DSLAM, but the IP Profile is administered by hardware deeper in the network and they cannot cap it.
They can band the connection speeds but that is all. The IP Profile can get stuck sometimes and 2 Meg is the usual value, it is not because a person forced it, but the joy of computers.

Had to explain my situation to the 7th person at PO support this morning. As a pessimist by nature my heart dropped further when he said that I didn't need an Engineer and they would escalate this to 2nd Level Support to change IP profile (what am I to know?), and I should hear in the next 48hrs.
Late morning my phone rang and spoke to what must have been someone with clout because he said the IP profile was stuck and they had now changed it. This afternoon my IP profile was 6.0Mbps and this is TBB speedtest:
http://www.thinkbroadband.com/speedtest/results.html...
Yippee.Fingers crossed.
I had noticed my Upload rate still remains at 448kbps but I'm hoping this doesn't matter. Thanks to everyone for the information which encouraged me to pursue this.

Success 
May we see the full router stats incl. connection/sync speeds? I don't believe we've yet seen a complete set.
And what exchange?
Giving us all this fully will enable us to give you a definitive answer on the 448K Up Sync.

There are two tabs in the router which seem to have "stats" but I'm not sure this is the information needed. Anyway I've summarized all the information which hopefully is relevant:
ZyXEL AMG1202-T10A
ADSL G.dmt Annex A/L/M
ADSL 6304 / 448
LAN 100M/Full
WLAN 150M
DSL line Status:
relative capacity occupation: 55%
noise margin upstream: 20.0 db
output power downstream: 19.5 dbm
attenuation upstream: 24.0 db
followed by table of tone bits
relative capacity occupation: 121%
noise margin downstream: 5.0 db
output power upstream: 12.0 dbm
attenuation downstream: 47.5 db
followed by table of tone bits
Latest - a few minutes ago
BTW speedtest Download 5.18Mbps, Upload 0.39, Ping 41.25ms
DSL connection rate 6.02Mbps down, 0.45Mbps up.
Likewise latest TBB speedtest
http://www.thinkbroadband.com/speedtest/results.html...
Not sure if this link will work as I've a few problems copying and pasting here. Let me know if any other info will help. Many thanks

ADSL G.dmt Annex A/L/M Is that on a page where you can make your own settings or on a page just reporting current status? Clearer to copy verbatim rather than summarize as you may make assumptions about things you may not know.
The presence of the Annex choices makes me suspect they are settings. In which case you could try setting ADSL2+ (G.992.5) there. However if it is really the current status then G.DMT explains the 448K Up Sync. If you would just tell me your exchange, as I keep asking, I would be able to tell you whether G.DMT is all you can get there. BTW speedtest Download 5.18Mbps, Upload 0.39, Ping 41.25ms
DSL connection rate 6.02Mbps down, 0.45Mbps up. What about the IP profile?

Sorry I forgot to let you know the exchange nearest is Diss in Norfolk which is about 2.5 miles away. The router was supplied by the Post Office and its pages are completely alien to me despite downloading the manual - I just don't understand the technical terms.
The 6304/448 was on the Status page and has been showing 6016/448 since yesterday evening. It has also shown 6336/448 so I assume this is the DSL rate . Speed has also now dropped back to about 4.75Mbps but this is fine for me providing it doesn't deteriorate. I'm unable to copy and paste or print the displayed pages from the router. The other figures are shown under Diagnostics page - DSL tab. I understood that ADSL2+ was available from about this time last year.
Sorry again - forgot IP Profile. It has been 6.0 since they intervened Tuesday ( 16th) and I've just done another check.
BTW test: Download speed 5.18Mbps. 7.15 maximum achievable speed. DSL rate 6.02 Down 0.45 Up. IP Profile 6Mbps

You connection stats are currently extremely good. It was a stuck or recalcitrant IP Profile that was causing the problem. It may have reduced because you had noise or discons on the line before. It is now 6 Meg. Just keep an eye on it.

Sorry I forgot to let you know the exchange nearest is Diss in Norfolk which is about 2.5 miles away. . To find which telephone exchange you are connected and the line distance use SamKnows. 
http://www.samknows.com/broadband/exchange_search
For distance from your exchange Go� Broadband Checker > Search > then Locality.
http://www.samknows.com/broadband/broadband_checker

the line distance use SamKnows. No, straight line distance: Locality
Note that this is the straight line distance - the actual cable length will be longer! In my case the line length is 2 km but the straight line distance is given here as only 801 m.
EDIT: It is only line length that is important!

Thanks again for the replies - still IP profile 6Mbps & keeping my fingers crossed as it will be a week come Tuesday. I used "Sam Knows" and it shows a distance of exactly 3.969km or about 2.5 miles in real money from Diss exchange. When I look at the services available it cannot find my address although the drop down menu shows my house! However when I use the old name of the house it then shows availability of 1 Mbps ADSL or BT 21CN services along with Talk Talk and Sky. This makes me suspect some of their databases may (or may not!) be a little bit out of date.
