Whilst I was away I had an email from Plusnet saying my connection has improved from an estimated 13mbps to 21mbps but this isn't the case or,if it was, my profile has fallen dramatically over the training period
Today's results from BT's Speedtester
Download speed achieved during the test was - 6562 Kbps
For your connection, the acceptable range of speeds is 1000-7150 Kbps.
Additional Information:
Your DSL Connection Rate :9120 Kbps(DOWN-STREAM), 896 Kbps(UP-STREAM)
IP Profile for your line is - 7150 Kbps
The throughput of Best Efforts (BE) classes achieved during the test is - 13.12:22.71:64.17 (SBE:NBE:PBE)
These figures represent the ratio while sententiously passing Sub BE, Normal BE and Priority BE marked traffic.
Plusnet Profile
Phone exchange: WATFORD
Estimated line speed: 7 - Checked on 2010-06-01 10:30:55
Current line speed: 7150
My router settings are
ADSL Link Downstream Upstream
Connection Speed 9123 kbps 896 kbps
Line Attenuation 35.5 db 17.8 db
Noise Margin 9.3 db 5.9 db
My pings and down load speeds were very erratic for 12 hours after the re-boot but seem to have settled down now.
I am currently using a Netgear DGN2000. Do I need to do anything to make it connect on ASDL2+ or would that happen automatically?
It looks like I still have this Assured Profile of 7150kbps (which is something Matt T was looking into) on my profile so even though my router is syncing higher I am still capped at 7150kpbs. Can my profile get a nudge?
Additional Information
After pulling out my hair trying to game over the weekend, I switched to a different Netgear modem and noticed that my downstream noise margin is very erractic. Polling the modem every second my noise margin was jumping around between 4db and 9db last night (peak period) whereas this morning (off-peak) it was still jumping between 5db & 9db. Is that normal?
Err, help!

I was having real trouble gaming over the weekend so since the initial post I have tried several router configurations. Each time I have done this the sync rate achieved has been between 8.5 to 9.2meg download and pretty much 1meg upload.
The last one was around 10pm last night (after the first router just froze) so I took the opportunity to switch to a different but older router. As this was during a peak period I know the sync rate fell just below 9meg ( from memory I thought it was 8.8meg but didn't think it was as low as you state) and the upstream was about 961kpbs having previously managing 1000kpbs with the first router
You may not recall but whilst I was transferring over to 21CN the first BT speed test mentioned an assured profile of 7150kbps. It doesn't mention 'assured' anymore but the 7150kbps seems to have remained even though I should be able to achieve much higher. I had got particularly excited when the Plusnet email said I had a current speed of 21meg.
I cant see why my profile should have been reduced to 7150kbps if plusnet advised it was 21000kbps within 10days if I haven't suffered any disconnections.
The only other thing I have noticed is the volatility of the download noise margin. Is it normal to be jumping around so much per second? Could it be a line or router fault?
Also am I still definitely in the Pro package as gaming is just awful. I can physically see that it has trouble streaming even the simplest of banner graphics before even joining a game at times?
It's a shame really as I have only been with Plusnet for 3 weeks and in this time I have gone from ADSL, to 21CN, to ADSL2+, and statistically it's shown some minor improvement but gaming hasn't.

Looking at your connection logs it does seem that there's a fair few disconnections on there which would explain the wavering SNR and also the low profile. Are you not seeing these disconnections from your end of things?

The data pre 7th June can be ignored as this was when various testing was being done with BT on the old ADSL network.
My training period was reset on the 7th June just before I migrated over to the 21CN network. During 8th & 9th June I was migrating over to 21CN and then onto ADSL2+ so I guess that is what the disconnects were then. I am not sure about the disconnect on the 11th but I know that my order to have my upstream uncapped was being processed whilst I was away so maybe it was that?
The disconnects on 19th was upon my return to ensure all the amendments were picked up by the router. And on the 20th that was me pulling my hair out and trying various configurations to get a decent connection for gaming.
However, the email I received from plusnet on the 9th said my current profile was 21000kbps just as I moved to ADSL2+. From the 9th until the 19th I had one disconnect which was probably the upstream being uncapped. Otherwise a perfect training period. Upon my arrival home on the 19th and before all the disconnects I could see that my profile had already fallen to 7150kbps. It looks to me that the "Assured rate of 7150kbps" that Bt put me on when they migrated me to 21CN has stayed in place and the Plusnet profile of 21000kbps has just reduced itself to match.
That surely can't be right.
Am home now so can also give you the following test data
Router Stats
ADSL Link Downstream Upstream
Connection Speed 8199 kbps 992 kbps
Line Attenuation 33 db 9 db
Noise Margin 7 db 5 db
BTSpeedtester at 7.30pm ish
Download speed achieved during the test was - 7035 Kbps
For your connection, the acceptable range of speeds is 1000-7150 Kbps.
Additional Information:
Your DSL Connection Rate : 8196 Kbps(DOWN-STREAM), 992 Kbps(UP-STREAM)
IP Profile for your line is - 7150 Kbps
The throughput of Best Efforts (BE) classes achieved during the test is - 15.65:22.66:61.69 (SBE:NBE:PBE)
These figures represent the ratio while sententiously passing Sub BE, Normal BE and Priority BE marked traffic.
Not sure why you can't see the upstream figure when you run the tests from your end. I could switch back to the newer router to see if that helps but I'm trying not to keep resyncing untill all of this is resolved.
Just to add that my pings seem to have got a bit worse today as well.
I ran BT Speedtester again at 9.45pm and got very different results (nothing has been changed at all)
Download speedachieved during the test was - 1451 Kbps
For your connection, the acceptable range of speedsis 1000-7150 Kbps.
Additional Information:
Your DSL Connection Rate :8196 Kbps(DOWN-STREAM), 992 Kbps(UP-STREAM)
IP Profile for your line is - 7150 Kbps
The throughput of Best Efforts (BE) classes achieved during the test is - 23.85:28.26:47.9 (SBE:NBE:PBE)
These figures represent the ratio while sententiously passing Sub BE, Normal BE and Priority BE marked traffic
Help, pretty please!

I transferred over to Plusnet on ADSL to get the 8meg service but then saw that ADSL2+ was available so I migrated over to that and the original Plusnet estimate was for 13meg upload ability. The same 13meg was quoted on the BT exchange checker.
As I transferred over to ADSL2+ BT gave me this Assured Profile of 7150kbps and at the same time the BT Exchange checker dropped its estimate to 7meg which I assumed was because it could see the assured profile. Once on ADSL2+ the Plusnet profile was set to 21meg but the BT profile is still stuck at a crumby 7meg.
Could you please test my line again, as you did at the top of the thread, and see if you can obtain an upstream reading (which you couldn't yesterday)
Can you also check that I am on the Pro package because my pings are very erratic since the migration and as the BT tests provided above show that my upload ability collapsed from 7035kbps to 1471kbps last night. I know there is a bit of volatility when the network gets busy but to fall from 7meg to 1meg seems rather a lot.
It just makes gaming pointless and gaming is the reason I moved to Plusnet.

The test is showing your downstream at 8888kb/s and upstream as 992 so it's looking alright. As for Pro, you're on the Extra account - not sure when you put the request in to move across but I'll take a look for you and get back tomorrow morning and see what's going on there.

On the modem side it seems I had two random disconnects one straight after the other around 2pm - the router had remained powered up so are you able to tell if it was something at your end that may have caused this?

Beg pardon, you are indeed on the Pro account - sorry about that.
Regarding the disconnects, they're showing as "unknown (Termination by server side (NAS) Modem)" which confirms that it wasn't caused by anything at our side - it's usually interference or a drop due to something either at the exchange, on the wiring or possibly interference within your own premises.

The faults department have asked me to connect to the test socket, again, for diagnostics and I'm back to getting to getting strange results from the BT Speedtester again.
The service was unable to ascertain my DSL connection rates and also this dreaded Assured Profile has reared itself again.
Test1 comprises of Best Effort Test: -provides
background information.
Download Speed 6861 Kbps
0 Kbps 7150 Kbps
Max Achievable Speed
Download speed achieved during the test was - 6861 Kbps
For your connection, the acceptable range of speeds is
1000-7150 Kbps.
Additional Information:
Assured Rate IP profile on your line is - 7150 Kbps
If you wish to discuss these results please contact your
ISP.
Does Plusnet lend out it's own preferred ASDL2+ router that I could test with?
I'd be surprised if my new Netgear router was causing any issues but it would help eliminate the possibility and I am loathe to purchase the Plusnet one if it is unlikely to make a difference.

Yeah, we'll send you a test router out, normally takes about 2-3 working days.

Maybe a dumb question but -
My router is currently plugged in to the master test socket whilst Plusnet runs some diagnostics via an adsl filter of course. However I have just noticed that if I plug a phone in to the phone socket on the adsl filter it causes the LCP to go down and then come straight up againwith a resync.
Is that to be expected or should plugging a phone in make no difference.

Plugging a phone into the filter should not cause any issue at all. Either the filter or the phone should be changed to eliminate this.
