Guys sorry i didn't upload the stats sooner.

I am definitely not isp / telecoms / router savy at all. I know the bare basics of how to get about the router and manage my home connections.

Also by "hypothesising" i was actually trying to learn about the technical side as i didn't actually understand what a lot of the technical terms are i.e. attenuation. Also the reason why i was hypothesising was to be corrected if my understanding was incorrect.

Back to the router stats:
I did swap over the routers to the new one supplied,.

Here are the stats:
Port Status TxPkts RxPkts Collisions Tx B/s Rx B/s Up Time
WAN PPPoA 241944 383448 0 923 20886 06:38:22
LAN 10M/100M 253197 200147 0 11837 843 07:20:16
WLAN 11M/54M/150M 228695 101322 0 9720 536 07:20:19

ADSL Link Downstream Upstream
Connection Speed 17056 Kbps 1134 Kbps
Line Attenuation 24.1 dB 12.1 dB
Noise Margin 2.9 dB 5.3 dB

Stats which make more sense!

Quick tutorial (non-geeky version):

Sync - Speed of connection...modem to ISP

Profile - 88.2% of sync (or should be - a BT speedtest shoudl show this) - set by BTw and can fluctuate if line not too stable.

Throughput (actual speed of line) - approximately 94% of profile.

Attenuation - Resistance...lower is better and tends to give an idea of distance from exchange. 24.1dB suggest around 1.8km from exchange. The longer the line, the more metal the signal passes thorugh, the more resistance (attenuation) experienced.

SNR - Signal to noise ratio - higher is better - the name sums it up really; it's the amoung of signal to noise, so higher signal to lower noise (noise is basically interference) is better. Generally set at 15, 12, 9, 6, or 3...ISPs should set this to 6 if the line is good for it. Tweaking to 3 (and some routers allow for 4.5dB settings) allows for higher sync, but more noise, so more line errors and a better chance of line drops...and the sync drops...and the SNR rises.

I suggest you reboot the router between 6am and 8am, and see what the sync is. If better, visit BT speedtest soon after and that should raise the profile of the connection. If your ISP follows up with the profile change, your speeds will rise too. Some folk recommend a time before lunchtime for reboots. Opinions vary.

Rough guess... best sync of 19 Meg and speeds of 17 Meg on 3dB SNR.

they estimate my adsl too high.

sky estimate 9meg for adsl on my address haha, I also remember talktalk telling me a very silly high number over the phone which was in double digits.

IIRC it is you with the very unusual noise margin behaviour. In general, daylight hours is the important factor. So in the summer, 6am-8am fine, but for most people that would be a bad time in the winter.

Visiting the BT speed test doesn't affect the profile, it just reports it. (We don't want to imply something to this OP that isn't the case).

If your ISP follows up with the profile change, your speeds will rise too.

Very few ISPs apply copies of the IP Profile. I doubt if Orange do but don't know for sure.

Ah - as covered above .

Hence the suggestion. There's room for other time tests after.

Splitting hairs. If I visit the tester then wait a day, my profile can rise. Not always, but it can. If...not sure what triggers it...Plusnet have their systems aligned...or I have a reboot after the test. It's difficult to nail down which...probably the latter.

Indeed, but the statement stands. If the ISP doesn't raise it, that's another problem for the OP later.

That's more like it! The previous figures were corrupt.

From that Attn. you should be getting 19 Meg Sync & throughput of about 16 Meg on speedtests. You reported you had previously got 15 Meg on speedtests. At that time you would have been syncing at about 18 Meg, faster than now.

As others have requested, reboot your router during daylight hours and repeat these stats.

Then run the BT Speedtester "ADSL and FTTC Diagnostics" (not the Beta) and copy & paste back just the text results.

It wasn't you who was hypothesising

@ Roberto: There is no indication that Orange keep their own copy of IP Profile like PN; we never see PN-like discrepancies. As Orange actually have BTw managing their BB they would have no reason to.

Indeed. I'll update my guess. Working more in the 10-13 Meg range, I'm more in the habit of knocking off a couple of Meg. The losses fairly increase as the sync rises.

Exactly my logic for saying what I did .

Don't PN used BTw WMBC for their BB?

And why would BTw management of the BB end up with no reason for Orange to have to match speeds? I though BT required it of *all* ISPs... even if not all of them do it.

BT Wholesale does not require all the ISPs to shadow the IP Profile in the same way that Plusnet do
