You were not on a fixed 2MB profile, the reason for your reduced speed was your high noise margin (27dB) on downstream.

Yes, that high NM was damping OP's speed to 2 Meg. Why were you setting it so high in the 1st place?

In reply to a post by UKDoc:

Your new stats show 0.9db noise margin.

Far too low! Line's going to be very unstable.

In reply to a post by UKDoc:

so your full speed is back at 13-14mbps which is typical for line attenuation of 17-18dB.

Perposterous! 20-21 Meg is typical speed @ 18 dB attn.

You can keep an eye on this and let us know if you have any further issues.

With a 0.9dB margin at the time he took those stats, further issues he will certainly have. As for expecting 13-14Mbps sync/connection speed on 18dB attenuation - as XRaySpeX says, that is garbage.

(Edit - last sentence removed as it was due to my misreading part of XRaySpeX's post).

Quite what Orange have done to try to sort out your speed problem is a bit unclear. As I've just posted in reply to their rep, I think you will have had disconnections this evening.

Can you tell us if you did, then during daylight take and post the stats again, then turn your router off for 10 minutes.

Start it up again, and read the stats as soon as possible after it connects. (Don't panic and rush, just don't wait for any significant time).

The 10-minute switch-off would be better as 30 minutes if you can bear that . That allows other settings in the system to clear down. These should be within a couple of minutes, but sometimes it takes longer. My suggested ten minutes is usually enough, 30 minutes should almost guarantee it.

The stats from immediately after the reconnection give us important information, in particular the setting they have for the sync-time noise margin, which significantly affects your connection speed.

Following on from that, and whatever it shows, we need to look at why you never got more than 14Mbps sync in the first place, before your router started playing up. As XRaySpeX says, around 20Mbps sync should be possible, with 18Mbps being the least you should expect.

This problem could very well be to do with the way things are set up and wired at your place.

Hello RobertOS, XraySpeX

I am just here to try and help customers and am not looking to get into technical debate/flame war with the thinkbroadband residents .

In a pure noise free environment 17-18db will give around 20Mbps. The line rate I quoted 13-14Mpbs included a typical noise margin value, but yes agreed you can get some where in between.

The reason for the high noise margin in the first instance (and subsequent very low) is not clear which is why I have asked 'dsharp67' to let me know if he has any more issues and the team that did the reset are continuing to monitor.

Regards

The line rate I quoted 13-14Mpbs included a typical noise margin value

This is not a question of flaming, it is a case of simple misinformation.

You personally may not be at fault in this, but whoever in your management or training systems have told you that 0.9dB is a typical noise margin value, especially if that is necessary to achieve a non-typical 13Mbps on 18dB attenuation, is not being fair to you or how you appear here. It is simply not true.

The speeds I quoted give the user a target to aim for by addressing, if necessary, any simple home wiring issues within his purview and not settle for second-best.

There is no flaming taking place. This is a Forum where we can all express our opinions. These will inevitably include technicalities.

i think ive got a similar issue. Had line fault which was fixed a couple of weeks ago, broadband speed dropped as a result. Line fault fixed but broadband speed didnt recover.

ADSL firmware version : A2pBT009c1.d17d
Connection mode : ADSL2+
Type : Fast
Noise margin (dB) : 12.1
Attenuation (dB) : 39.0
Attainable download rate (kbps) : 2470
ADSL status : Connected [0]

Downstream Upstream
Rate (kbps) 2434 324

I used to get a speed of around 5 but now seen stuck at 2

39dB attenuation and 5Meg was below average connection speed.

What you need to get back to the 5Meg is for the 12 dB Target Noise Margin you appear to have to be dropped to 6dB

Hi Pete1970,

If you want to drop me a Private Message, with your broadband line number and a contact number I will get someone to call you back, to look at your line again.

Regards

I don't know if you would consider this a stuck IP profile but I when I signed up for Orange broadband back in April 2011, my estimated line speed was 17MB. Right now after taking a speed test my stats are:

Download speedachieved during the test was - 10.43 Mbps
For your connection, the acceptable range of speeds is 4 Mbps-21 Mbps.
IP Profile for your line is - 10.95 Mbps

Upload speed achieved during the test was - 1.05Mbps
Additional Information:
Upstream Rate IP profile on your line is - 832 Kbps

I am using a TP-Link W8960N router because the Netgear DGN1000 was terrible. My router stats are:

Mode: ADSL_2plus
Traffic Type: ATM
Status: Up
Link Power State: L0

Downstream Upstream
Rate (Kbps): 12483 1215

Downstream Upstream
Line Coding(Trellis): On On
SNR Margin (0.1 dB): 116 51
Attenuation (0.1 dB): 285 114
Output Power (0.1 dBm): 0 127
Attainable Rate (Kbps): 15108 1200

With these download margin and attenuation stats, I believe I should be getting 15MB-17MB. When I called Orange on Monday 12th March, and asked why I am not getting a faster download speed the guy from India said that if my download speed was faster, than the line would become unstable and I would get disconnected. What I wanted to know is whether or not this is true?
