ADSL2 Regrade - slow connection

[clinton]

Hi, so today my ADSL2 was activated on my line, it was a fairly decent ADSL MAX up to 8mb, which I would get 7mb down on before the regrade.

This morning when I first checked the speed, I was getting about 17.5/0.9, but  since lunchtime only this painfully slow 287kbps down and 440kbps up

Now I know it's only the first day, but since this lunchtime the connection has stayed at 287Kbps Down and 440 up. Is this normal, will the connection improve on it's own, or should I be talking to somebody about it?

Here is the line stats, I reset the router to see If that would help, hence the low connection time.

Line state: Connectedppp0_0 Connection time: 0 days, 00:27:58 Downstream: 287.1 Kbps Upstream: 440 Kbps

ADSL Settings VPI/VCI: 0/38 Type: PPPoA Modulation: G.992.5 Annex A Latency type: Interleaved Noise margin (Down/Up): 30.1 dB / 28.1 dB Line attenuation (Down/Up): 19.3 dB / 9.3 dB Output power (Down/Up): 18.3 dBm / 11.6 dBm FEC Events (Down/Up): 0 / 0 CRC Events (Down/Up): 0 / 32 Loss of Framing (Local/Remote): 0 / 0 Loss of Signal (Local/Remote): 0 / 0 Loss of Power (Local/Remote): 0 / 0 HEC Events (Down/Up): 0 / 7 Error Seconds (Local/Remote): 0 / 0

Hi,

I'd just like to clarify something in regard to profile resets.

When these first became available it was the case that further faults on the line could not be raised for the entirety of the 10 day period.  That has, however, changed in the past year or so.

When a profile reset is put through the main effect should happen in the first 24 to 72 hours, and in most cases it's been done as part of the fault process anyway, so there should usually already be a case open.

Also there should be a callback booked for a few days after the reset to check if its worked or not.  If you don't get this and the connection is still broken then you should call in to the Helpdesk.  There may be any number of reasons why they didn't contact you, and it's better to phone in and make sure the case stays active, rather than waiting for ages and having to start the whole process again.

Thanks that's good to know

Just an update on my situation...

After a chat with support this evening; Wednesday night an engineer did a lift and shift, and also at some point the IP profile for my line has changed from 0.25Mbps to 6.11Mbps. However I'm still only getting between 0.19 - 0.24Mbps down. Router logs show that I'm getting fairly consistant FECs and some CRCs along with a few hundred Link Retrains.

This is the stat's from the 2Wire 2700.

The Noise Margin is a lot lower and the Attenuation a bit higher than what was reported on the BH3, whether that's due to the engineers work or just different methods of reporting from the routers I'm not sure.

Down Up

Modem Type:	Built in modem - ADSL
DSL Line (Wire Pair):	Line 1 (inner pair)
Current DSL Connection:
Rate:	6925 kbs	444 kbs
Max Rate:	15913 kbs	876 kbs
Noise Margin:	10.8 dB	30.1 dB
Attenuation:	22.6 dB	9.3 dB
Output Power:	10.1 dBm	12.1 dBm
Protocol:	G.DMT2+ Annex A
Channel:	Interleaved
DSLAM Vendor Information	Country: {46336} Vendor: {IFTN} Specific: {48753 }
ATM PVC:	0/38
Rate Cap:	15913 kbs
Attenuation @ 300kHz:	22.6 dB
Uncanceled Echo:	-21.4 dB	Ok
VCXO Frequency Offset:	5.8 ppm	Ok
Final Receive Gain:	14.6 dB	Ok
Excessive Impulse Noise:	0	Ok

Unfortunately I still get this,

This is what I had for a few hours on Monday,

Notice the difference in Ping also, I presume this is mainly due to Interleaving now being switched on, it's really important for me to have a low latency and when this problem is sorted I hope I will be able to have FastPath constantly enabled.

I'm nearly regretting going ahead with this regrade atm, I should have done more research into ADSL2+ and possible consequences. I would definitely sacrifice some speed for lower latency and I might have been better off staying with my stable FastPath Max connection.

What exactly is the usual speed you get if you are running at your normal connection?

[clinton]

Since the regrade average download speed is about 0.24Mbps, before on ADSL Max I would get 6.9Mbps if not more on a good day.

Here is the training log from this morning,

The Connection is now stable again but still so slow;

You are currently capped at 288kbps down and 444 kbps up - the line sync speed looks excellent very few errors &c.

Get through to support and get them to look at that image - it is obvious and if first line is not able to sort it within a few minutes you need to get them to escalate it to second line with them to call you within an hour.

They have decieded to send an engineer round on Monday.

This is starting to become hard work now

Engineer came round yesterday, everything was fine my end, really good line and all my equipment was fine.

He said that I was band capped up and down and that he would get both reset.

However it seems that only my download has been reset, with the noise ratio brought down from 30Db to 6Db, and my DL speed is now averaging 15Mbps.

The upload however has remained at 30Db and as expected the upload speed has stayed the same about 0.35Mbps up.

So I would say that I'm still band capped on my upload.

Now to the hard work part, I received a follow up call just now to check if everything was okay. Obviously i tried to explain that I still needed to get the upload speed fixed as it was still band capped, to which I was told that BT do not cap the upload and that the speed I was getting was acceptable, and I now need to wait for the ten day training period to complete.

Fantastic, so I expect I will need to spend another several hours going though this process again in ten days time.

Probably the most annoying thing has been that no body has really explained to me what the problem actually was.

It cost me an hour in phone calls but finally have my connection sorted.

Somebody from BT phoned yesterday and told me they have now removed the cap on my upload, and sure enough I now have a really nice connection
