Re: Just Got Up And Running After 4 Weeks

It's obvious from the stats that you are losing sync periodically due to some sort of line problem. The uncapping will have nothing to do with this (although it's been know to exacerbate it). That new Current Line Speed is consistent with the current sync speed and profile. What's perhaps slightly surprising is that Interleaving hasn't been applied, unless you've had it turned off for Gaming.
Try pinging ntp.plus.net from a Cmd prompt and see what results you get.
You really need to get the corded phone to check out that potential issue!

Re: Just Got Up And Running After 4 Weeks

Just ran the BTw speed test and it shows:
Download speed: 7.51Mbps
Upload speed: 0.87Mbps
Ping: 38.25 ms


Further Diagnostics:
IP Profile for your line is - 7.06 Mbps

I did notice there's been a resync from the upload time.All was well until I had the upload uncapped.Interleaving was on but it just came off again a few days ago.
I was told uncapping upload takes speed off the download side but others say it doesn't...which is right ?   Undecided
Ping in command prompt result: 0% loss and 23ms average

Direct answer - don't know Shocked
However, there is a definite correlation between the movements of upload/download speeds on my line: The last change saw an upload increase of 50-60k and a download decrease of 100k Cry

Re: Just Got Up And Running After 4 Weeks

Sounds like it does come off the download side.It's too much of a coincidence that all was hunky dory for me until my upload was uncapped.
I'd still like the upload speed uncap undone.Wondering if I should get an SNR reset too while I'm at it...not happy losing 1Mbps off my download speed.  Shocked

Re: Just Got Up And Running After 4 Weeks

It is only supposed to be annex M on ADSL2+ that uses any bandwidth that would otherwise be used for DS, this is where the confusion has come about in recent times. Annex M is only offered on Business Lines by Plusnet. Even I've got "confused" in the past  Embarrassed
IIRC when the unload uncap activates there could be a resync. Line conditions at the time will decide on the sync speed.
I wouldn't pay too much attention to the ping result from the BT Speedtester. The ping from the Cmd prompt implies that Interleaving is off - consistent with the stats.
Judging by the last stats that you posted, and the time of posting, the last resync probably occurred at around 6.00pm. It's possible that noise conditions on your line has increased because of the onset of dusk and this has given a slower sync speed. If you still have a 6dB Target then a Daytime resync (using the Disconnect method) will improve the sync speed. But if the Target has gone to 9dB you'll probably get slightly slower.
You want to stop worrying about your Uncapped upstream and concentrate on getting a corded phone. I said at the outset that your line appeared to be under-performing for some reason.
A DCT member will be able to advise on the current Target.  And if you do have a line fault you will not be able to get a fault raised whilst a line is in training!

Re: Just Got Up And Running After 4 Weeks

Hi Glenn,
Uncapping the upstream should not be effecting your downstream.
Your target profile is currently set to 9dB which will be the reason behind lower downstream speeds.
This may be due to the disconnections on your line, have these been caused by you?

Re: Just Got Up And Running After 4 Weeks

That answers the question about speed coming off download to put on the upload....but as soon as the uncap happened my download speed dropped by the amount needed for the upload increase.  Shocked
You mention the SNR Margin....which stat do you look at ?...the SNR up or down ?...or an average of the two ?
Just checked again and it's: SN Margin (Up/Down) [dB]: 5,7 / 8,3
I did wonder if a shut down and reboot of the router might help.   Undecided
I definitely will get a corded phone to check for line noise.  Smiley

Re: Just Got Up And Running After 4 Weeks

Rebooting now will give you a slower speed as I explained in my previous post.
I think I'm banging my head against a wall here.
There's a bit of a pattern there with the disconnects. Is there any BT Openreach work going on at your Cabinet for example, or do those times coincide with anything eg. Central heating coming on?
Until you check you line, you do not know what might be going on. If you were to just raise a Broadband fault, then unless there was an obvious failure on the CIDT copper test, then the likely outcome would be, they'd suggest turning on Interleaving to try stabilising things, and the Raising of the Target SNRM is standard Exchange DLM behaviour to stabilise a dropping connection. Every rise in Target SNRM will lose you sync speed.

Re: Just Got Up And Running After 4 Weeks

Hi chris.....all I've done is disconnect the PPPoA session to gateway hop to see if that would help my speeds.I was told that it wont affect the DLM and that it was ok.
Not sure if those disconnects are me doing that....but I did gateway hop twice this morning and over the last number of days...since last weekend a week ago really.  Shocked

Re: Just Got Up And Running After 4 Weeks

@ Anotherone.....your not banging your head against a wall.There's been no one at the cabinet as far as I know.As for the disconnects...as I said all I've done is disconnect the PPPoA session in my router admin page and nothing else.There is nothing else I can think of that would coincide with those times no.

Re: Just Got Up And Running After 4 Weeks

Gateway hopping won't affect DLM. That's a Visual Radius log which shows the drops of PPP sessions, not a loss of sync, so if all those were you, then that's fine. For users that aren't dropping their PPPoA session by logging into the modem/router, such drops usually indicates a loss of sync. A loss of sync normally results in a drop of PPP session.

Ahh I get you....that makes perfect sense.Yeah they are the times I've gateway hopped.  Smiley

Re: Just Got Up And Running After 4 Weeks

Do the drops co-incide with the ringing of an incoming phone call?

@ jelv....no I don't have a phone plugged in as yet.The drops in that log are just from me gateway hopping.  Smiley

Re: Just Got Up And Running After 4 Weeks

Router stats I've just taken:
DSL Connection
Link Information

Uptime: 2 days, 19:53:38
DSL Type: ITU-T G.992.5
Bandwidth (Up/Down) [kbps/kbps]: 1.039 / 8.000
Data Transferred (Sent/Received) [GB/GB]: 1,20 / 1,79
Output Power (Up/Down) [dBm]: 12,6 / 0,0
Line Attenuation (Up/Down) [dB]: 17,8 / 36,5
SN Margin (Up/Down) [dB]: 5,8 / 8,3
System Vendor ID (Local/Remote): TMMB / ----
Chipset Vendor ID (Local/Remote): BDCM / IFTN
Loss of Framing (Local/Remote): 18 / 0
Loss of Signal (Local/Remote): 2 / 0
Loss of Power (Local/Remote): 0 / 0
Loss of Link (Remote): -
Error Seconds (Local/Remote): 82.665 / 1
FEC Errors (Up/Down): 0 / 0
CRC Errors (Up/Down): 186 / 12.752
HEC Errors (Up/Down): 238 / 27.478


My SN target is now 9dB I found out yesterday...but it hasn't seemed to have helped.The errors are worse if anything, even when interleaving was on after it got set to 9dB, and my download speed is over 1Mbps slower.
Everything was better when my target was 6dB....my browsing was noticeably faster and my file downloading was faster too, even with the error rates being as high as they were.
Can I get the SN target put back to 6dB ?  Smiley
