I'm moving to PlusNet on Tuesday. Below are my first weeks stats with an unlocked HG612 while still with BT..
How do they look ? Has the connection reset at any time?
Do they be any indication of what I may get with PlusNet?
I'll post the same from PlusNet when live..

Do they be any indication of what I may get with PlusNet?
There is no reason why they should not be identical with Plusnet.

There is a possibility speed will be slightly lower, but this is nothing to do with Plus Net.
The following two lines show his attainable speed (Max) and synced speed (Bearer)
Max: Upstream rate = 26294 Kbps, Downstream rate = 75984 Kbps
Bearer: 0, Upstream rate = 20000 Kbps, Downstream rate = 78364 Kbps
As we can see his downstream synced speed is quite a bit higher than his attainable, it is highly likely that the next time the modem resyncs for whatever reason his downstream will drop to around the attainable.
Whether changing ISPs will cause a resync I've no idea, either way the speeds are very good.

DLM hasn't intervened, and with an error rate that low, doesn't look to be a prospect.
My line runs at around 500 ES's per day, and gets no intervention. You are running at around 120.
Being on Plusnet should make no difference to *this* aspect of your line.

Thanks for the replies.
Is there any other stats or info it would be worth getting before the swap over ?
Thanks again.

Try to run a BQM: http://www.thinkbroadband.com/ping/monitors.html
Strictly, it needs a static IP, but it works with manual management of IP for a short temporary period (If your IP changes, remember to disable it, so the new owner won't get confused).
Getting a static IP at plusnet costs a one-off £5, if you feel like having this run long-term.
They have a page of BQM's here: http://community.plus.net/ping-graphs/

Delete rather than disable is probably better  .

Hi
Migration happened with out issue (so far) this AM. BQM shows my connection to BT went off at 1am. I entered my login details into my router and now I'm on PlusNet.
Stats so far..

BQM so far..
http://www.thinkbroadband.com/ping/share/e1b8df3b778...
Any issues to start with ?
I'll post some further details including speed tests in the PlusNet thread.
Thanks

The modem stayed synced all the time, which is what I would of expected, so there has been no change in your connection speed.
Has your actual ping time changed?

Has your actual ping time changed?
I've done 2 speedtest.net tests. Both show the ping as 18ms.
Since I put the HG612 in my ping has been anywhere between 19 - 35ms.
The last few speedtest test on BT were 28, 25 & 20.
PlusNet is showing a slightly faster upload/download speedtest result than BT - both using the HG612.
Ping from my PC to BBC and Google is 14ms
When I used the ECI modem I used to get a faster connection..(as seen on speedtest results)
Would it do any harm swapping back or do I need to give it a few days to settle in ?
|

You'll be quite safe to swap the modems around, just some things to bare in mind.
Power off the modem first.
Some recommend leaving it off for about half hour, personally I've never worried about this.
Don't continuously power down modems in quick succession.
Don't do it after dark as there tends to be more interference, lowering your sync.
Apart from the above general advice as your current attainable is lower than your sync your speeds will almost certainly be a bit lower, but of course the ECI might well negotiate a different speed to the Huawei anyway.
|
|
|
|
Thanks for the advice.
I'll leave it a few days as it seems to be working fine now.
From a speedtest point of view the connection is faster with Plusnet but only by a small amount.. not anything you'd notice in the real world.
|
|

Hmm.. had a couple of funny moments where I had no internet.
My PC which is connected directly to my router got upset, so I'm not sure it was a line issue or not.
But these are the latest stats from my HG612 any thing wrong or happened today ? thanks

Don't know regarding errors, but link uptime is 10 days 2 hours so it hasn't resynced recently.

Agreed.
There look to be only another couple of hundred errors in the last 2 days, so it isn't that either.

Thanks for taking a look.
Looks like it might have been an issue with one of PlusNets gateway's.
A couple of other users have posted about it on there forum.
Are there any docs or online guides to help understand the xdslcmd output ?
Thanks again.

If there are, they will stem from what RONSKI, WWWombat and Bald_Eagle1 have worked out  .

Any *easy* docs or guides?
What I've worked out for the output of xdslcmd as it relates to VDSL2 has come from a combination of reading the VDSL2 spec, and previously a variety of ADSL guides.
I found, in the past, there were some reasonably readable guides to ADSL on the net, but nothing for VDSL2. In the end, I resorted to the raw specs on the ITU website. Eventually, I got it - at least as much as a plain software engineer (who isn't a digital signal engineer) can manage.
The ability to understand (a portion of) those specs comes from a working life of reading & understanding telecomms specs, which dates back to being taught X.25 at Uni in the eighties.
I don't have a handle on all of the output, so there are probably a whole host of nuances that are just going over the top of my head.

It would be a good start to have a web page where you can paste the output and get an automated analysis, like we used to have with BE -
http://be.nfshost.com/
It's also an opportunity to aggregate some stats.

It wouldn't be a bad idea.
But would there be enough data to make for meaningful comparisons? The fact the modems are locked down means that only a few samples, from those willing to unlock, are really available.

Hey, I hope people don't mind me making use of this thread, I personally didn't see the point in making another one.
I just got my HG612 yesterday, i've unlocked it and installed the latest drivers. Here are my stats:

Yesterday everything was fine, Speedtests were getting me around 75Mbps down, 18 up and around 15ms pings to bbc.co.uk.
Today it has gotten a bit worse, my pings have increased to around 30ms and my speeds are around 70/18.
Also when looking at stats of other folks in this thread, my max rates seem crazy high compared to theirs, what is that about?

Max is crazily high because you are very close to the cabinet.
Actual downstream (Path) is below 79,999 because you appear to have a very noisy line with considerable interleaving.
How long had you had good speeds, and with what sort of modem?

Less than a day with the HG612.
I installed the modem around 17:00 yesterday and it was fine to start off with, this morning the speeds have decreased.
The HH5 was in for about 2 weeks with inconsistent speeds, but unfortunately I have been away for a week since the install and have not had the chance to monitor it properly.
Before I left and yesterday when I did a speed test with the HH5, it was similar as when I first used the HG612, 15ms pings and 75ish down.

Are those statistics from "yesterday" or "today" (whichever days you were talking about)? Do you have equivalent output from the other day? Which modem was plugged in "yesterday" and "today"?
On the statistics you give us:
DLM has most certainly intervened on your line, setting INP of 3 symbols both upstream and downstream, and setting "delay" to 6ms downstream and 5ms upstream. This has activated FEC and interleaving.
FEC protection is using 25% of your downstream bandwidth and 32% of your upstream bandwidth. The combination of interleaving delays will add 11ms to all you ping times.
The "usual" setting for DLM intervention downstream is for 3 symbols and 8ms, while upstream rarely gets any intervention.
I'd say DLM is trying to balance between the two with those settings, and setting a lower-than-normal "delay" for the downstream. The downside of that is that to achieve 3 symbols of INP protection, the modem has to use a lot of bandwidth. As a comparison, 3 symbols and 8ms would general result in just under 20% bandwidth overhead.
From the way DLM has intervened, your line looks to be being badly affected by noise. Unfortunately, the statistics don't cover a very long period to show this.
my max rates seem crazy high compared to theirs, what is that about?
Two things that combine:
1. You are close to the cabinet. Your downstream attenuation values of 5.4dB, 11.7dB and 19.7dB are pretty low.
Mine are 11.3dB, 27.1dB and 41.3dB with a cable distance of 350-400m, giving attainable values of 82/25; you must be considerably closer - within 200m would be my guess.
2. When FEC/interleaving is turned on, and actual speed goes down, something funny happens to the max attainable value: it goes up - usually by about the same amount as the actual speed goes down (this rule-of-thumb is seen downstream; intervention upstream is so rare that I don't think I could say what happens there)
That rule-of-thumb suggests your real downstream attainable value, if FEC/interleaving were removed, would be around 100.

I'm not making myself very clear, I apologize.
Basically, yesterday when I got home, I did a quick speedtest and ping on the HH5 where I got 75/18ish and 15ms pings to bbc.co.uk.
I switched out the HH5 to the combo in my signature (HG612 and WR1043) and the speeds were pretty much the same as on the HH5 yesterday.
Today, when I got up this morning, and the time of posting this, the speeds have dropped considerably to 70/18ish and pings are 26 - 30ms.
Unfortunately, I didn't save any stats from the modem yesterday, but the stats I posted above are from today. I also did the driver update today which didn't improve or even worsen the speeds.
It looks like there could be an issue with the HG612 i'm using.
EDIT: Saying that, my speeds and pings have been more consistent, sometimes when I did tests from the HH5 it would randomly get low speeds around 20meg.

So my pings are pretty much the same, they aren't bad I guess, but they are worse than they used to be.
Here is a speedtest I did this morning, the speeds around around the same or maybe slightly better: http://www.thinkbroadband.com/speedtest/button/13985...
Not sure what to think or do to be honest. I could put the HH5 back, and have reduced pings with all over the place speed, or stay as I am now with half decent speed and higher pings.
Would contacting BT about my issues be worth a try?

Alternatively, you could leave it alone and if it's stable, DLM may decide to reduce the interleaving on your line.

Yeah, good idea. Ill give it a few days then before I start whining again.
Is it possible that all the resets and messing around with firmware on the modem could have triggered DLM to add interleaving? As I said, it was fine to start off with.
|

|

Yes, DLM is interested in errors and disconnections. It takes about 10 days to remove interleaving once added, as long as the errors and disconnections have ceased.
But it may be longer - 2-4 weeks even.

Ok, thank you. I'll have to gain some patience and wait it out.

Are you aware you can monitor the stats with DSLStats?

No, ive not seen that one before. I've been messing around with PRTG, but ill give that one a try too!
I've got ping graphs on fruk.net running. Link
(The large packet loss is where I did a restart and my DD-WRT didn't update the DDNS for some reason until I forced it.)
EDIT: I'm using DSLstats now and its pretty great! It does all the telnet commands for me too so I can whine about stats quicker and easier, thanks!
I'll leave it running in the background, set it to run on startup too.

The HH5 has been known to have problems which can cause the DLM to take action, as BatBoy says leave it alone.
There is also another program for long term logging of stats, although it's designed to be left running constantly. It's called HG612 Stats Modem Stats. A lot of people run both in combination though you have to make sure that they aren't timed to collect the stats at the same time. I think this is virtually automatic now as long as you leave HG612 to collect at 0 seconds.

My connection at work just clocked 405,210 FEC errors in the last minute, and it's been running fine like that since last July. They've tended to vary between 100k to 500k per minute, so I would not worry about 12k a day
If fact I'd hazard a guess that if they are that low then your interleaving will be reduced at some point.

Good morning everyone. Just a little update as I fired up DSLstats this morning to find out Interleaving appears to have been turned off completely already! So that was a lot faster than expected.
The stats look more like this now:

So thankfully my pings are back to normal now and the speed has increased back to normal too. Strangely there are all sorts of errors occurring now.
In the bottom corner of DSLstats it reads that the modem has been up for 1:21:23:51, but the DSL has only been up 8:51:23. Does that mean it was reset when DLM changed or is there something else for me to concern over?
Also, am I right in assuming as long as the modem stays connected, I can restart and play with the router as much as I want without upsetting DLM again? I wondered this because it often causes an IP change.

Your IP address changes because you don't have a fixed IP address and disconnecting the router breaks the connection between you and your ISP, which runs over the connection between the DLM and modem. The modem maintains the connection between it's self and the DLM independently of the ISP connection.

Ah, thats good. I wasn't sure if DLM depended on a login or IP address from BT.
Thanks again

The 1:21:3:51 is the length of time the modem has been since last reboot. The DLM changed the line settings so disconnected and reconnected in order for them to take effect. Which is why your speeds have gone up and stats are showing Fast Path. The 8:51:23 is the time since the connection was re-established.

Right, so the connection does drop when DLM makes changes, thats all fine then. Thank you.
It's also nice to be able to see my line is managing the full sync speed now too, I was sceptical at first but it seems perfect now.

The post you linked to states the same firmware version that I have installed, where did you get 'A2pv6C038m.d24j'?

|

If you go to that link and go to the Experimental section I know for sure that the unlockedgui-noBTagent one is based on the A2pv6C038m.d24j as that's what I used a few weeks ago and I've had no problems with it at all, it also synced higher than I've had on the previous versions.

Oh right I see, i'll download it and flash this weekend probably. Thanks.

I think that post mentions the old firmware instead of the new, it's just a typo.

I've never really looked into what's considered normal for FEC errors, is an estimated 12k per day ok?
Now DLM has de-intervened, I guess we have something of an answer to that.
While it seems clear that DLM monitors the 24-hour ES values in choosing to intervene, it isn't at all clear how much attention it pays to the FEC rate (vs the ES rate) when choosing to de-intervene.
It is good to see your line is back to 80/20 speeds, as it seemed to be clear that it *ought* to have supported that. In looking at your stats again, I've noted two things:
1. The attainable figure dropped a little after FEC/interleaving was removed, but not as much as I expected. That is interesting for watching in the future, but this disparity might have been caused by...
2. When DLM had intervened, and your speed was 77Mbps, I concentrated too hard on the FEC/interleaving settings. One aspect I missed was that your downstream SNR values were all much higher then 6dB
That suggests two things:
a) That your speed (at the time of taking the stats) could have gone much higher - and a manual resync would have probably restored a full 80/20 sync, even if it would have left the DLM-triggered higher latency in place
b) That the reduced speed (at the time of syncing at 77Mbps) must have been affected by a lot more noise on the line, that has since disappeared. The sync would have targeted an SNRM of 6dB, so the increase of SNR values from 6dB to 11-13dB must have happened after the sync by removal of noise.
The best conclusion is that you have some source of noise around that acts (or acted) intermittently. You might want to leave the stats gathering in place, in case it returns...

I've never really looked into what's considered normal for FEC errors, is an estimated 12k per day ok?
Er... my last 1 day FEC count was 5,910,605 from a new noise source in the past 48 hours. However, DLM seems to be managing this with its current settings. ES is still around 200 or less and CRC about 800, both per day.
Wherever it's coming from it's not in the house though. See stats in sig for a live view.
