Fibre or not....

I originally intended getting FTTC when I moved to Zen (Lite) in November 2011, but by the time I got connected on ADSL and had a new socket & cabling installed, and got a Billion 7800n, I was so pleased with the ADSL (later ADSL2+) I decided to stay with it as stability and reasonable speed was all I needed with working at home.

Some people (me included) got moved last summer because of the olympics, and can't be moved back.

I noticed the difference as slow loading sites and slow to dowload email. It did improve a bit but I still get the slow response for websites and some pages. Interleaving also came on in June, and the noise margin reset early November.
More recently, I think I was moved again in November because although I have the fastest connection/sync I've ever had: ADSL 1092 / 9349 kbps, I still get odd delays with web pages loading and sometimes, slow to download email. It's not terribly slow, but not as fast as it used to be before summer.

My ping also went up from 25 on most Speedtests to 45 most of the time, but the same Speedtest I've always used gives me just over 8 down. (mostly 7.4 before).

My attenuation is 46 down, 28.8 up (pretty much what it's always been: NEALB exch), and the noise margins are on average 2.9 down 5.9 up during the day, 1.4/5.8 at night.

What I'd like to ask is, would my taking up the current Zen offer for installation of FTTC be likely improve the general overall stability and slow loading of websites at times ?

All depends on the reason behind the slow website loading. If the said website is slow because it needs MegaBytes of data then a faster connection will help.

If the problem is DNS look up times, or the server hosting the website then fibre (FTTC) will make little or no difference.

Thanks - it's a problem I didn't have before getting moved but that's as much as I know really. Something must have caused interleaving to begin too.
The slowness can happen with any website - sometimes fast to load, other times slight delay, odd times a little longer.

Not sure if these two tests would tell you anything -
I just used Visualware to do a test to my IP number and it gives green lights for all the reults.

But when I tried entering Zen.co.uk it had a couple of problems:
DNS lookup time was 404 ms. There could be problems with the DNS server on the otiginating network.
Hop 1 is responding in an erratic manner, varying between 30 and 258ms response time. Could be indicative of a problem at this point.
100% packet loss due to firewalls

Hop 1 is usually your local router, try setting the PC to use the ZEN DNS servers, rather than the router, it may help things. If that does not help then try the google DNS servers 8.8.8.8 and 4.4.4.4

What "moves" were those please TrishaH? One of them perhaps ADSL to ADSL2+, but what was the other. And in what order?

I still get odd delays with web pages loading and sometimes, slow to download email. It's not terribly slow, but not as fast as it used to be before summer.

This is very odd - seemingly associated with the first move. Which is why I'd like to know what was what. The end result of ADSL2+ at that sort of level should have been a hardly noticeable faster website loading and for email you shouldn't really have noticed any difference at all.

My ping also went up from 25 on most Speedtests to 45 most of the time, but the same Speedtest I've always used gives me just over 8 down. (mostly 7.4 before).

The ping increase is almost certainly caused by interleaving being turned on.

My attenuation is 46 down, 28.8 up (pretty much what it's always been: NEALB exch), and the noise margins are on average 2.9 down 5.9 up during the day, 1.4/5.8 at night.

That implies your sync-time noise margin has been lowered to 3dB, as that's a very high sync speed for the attenuation.

It does seem that in some cases that lowering of the noise margin can be counter-productive, and the DLM has been over-optimistic. The lowering happens automatically with the latest version. I'm a bit concerned that you may be getting packet loss or errors that aren't bad enough to revert you to 6dB, but bad enough to degrade the real-life perfomance. Despite (in fact because of) the higher sync speed.

What I'd like to ask is, would my taking up the current Zen offer for installation of FTTC be likely improve the general overall stability and slow loading of websites at times ?

Likely, yes. certainly, hard to tell with the information we have at the moment. (I haven't gone back to past posts). ... OK, just read the "Ping" thread.

I have a feeling you have some sort of small fault, possibly on the line card at the exchange (which FTTC should cure, but if it is your end it won't) - but this all doesn't add up.

Re FTTC itself, samknows doesn't recognise the code you give for the exchange. Better anyway for FTTC checking would be your postcode. Here for more opinions, PM would do.

I've just checked the Zen site. I see you only have till Sunday to decide. But!

I expect you went to Zen for the reassurance of their reputation for performance and support. Exactly why I went to IDNet (for FTTC) from O2 LLU. A year on, with trembling fingers, I migrated to Plusnet FTTC for a hugely lower cost. I have no regrets whatsoever. Have a quick look at their website once you've answered my questions .

I'll happily try the change you suggest, but will answer Bob's questions first if that's OK.
I'll need to ask you how to try these DNS servers anyway

It was just before the olympics - visits to my own website show my server location, and prior to that, I was 'Westmister'.
Not long after I noticed the slowdowns I saw that I was showing as 'London'. It was about that time that I found that people had been moved because of the olympics.

In early November I lost connection and it synced at 8224/695 so I called Zen tech dept and he had me unplug the router. It reconnected at the right up speed but sometime during that night, it disconnected and re-connected at the 9349/1092 that I now have and the SNR had been re-set according to the Zen line data.
It was around then that my location showed up as 'United Kingdom' - hence me thinking it was another move. I had asked if I could be put on the pre-olympics connection I had but apparently they can't do that.
That disconnection in early November that resulted in the slower up speed could have been a BT maintenance thing as far as I recall, but I don't know what it was that they did.

(When I upgraded to ADSL2+ you did help check that I was getting the right speeds etc. There wasn't a lot of difference as you say.)

I did understand the ping once it had been explained here.

Twice Zen tech people have mentioned errors on the up part of the line but didn't seem overly concerned.

I'll PM my postcode. If I did go for the FTTC, it would be the lite version so wouldn't cost much more each month.
I do like Zen and they've never been anything but helpful if I've had queries or the initial difficulty (router), etc.
Just wish I had the same trouble free connection I had for the first 7 months! I'm one of those people that hate tinkering around with computer stuff, and hope that any changes just 'get on with it' as it were

Plusnet does look good, so if I ever do want to move, I'll likely choose them

Ask Zen if they can set a 6db target noise margin instead of 3. That might help you out if there's errors building up.

I was thinking along the same lines as ukhardy07, TrishaH.

Also is it possible you could post your router stats, incuding the error counts, once a day for three or four days please?

Do you have a fixed IP address? I think you will have. In which case a thinkbroadband BQM rolling graph as per the one in my sig might be useful - packet loss is what I would be looking for.

Yes, asking for a re-set would be a good idea unless I take the fibre install offer.

Router stats for ADSL 5 minutes ago:
DSP Firmware Version A2pB025f.d22k
DMT Status No Defect
Operational Mode
ADSL2+
Upstream 1092
Downstream 9349
SNR Margin(Upstream) 5.9
SNR Margin(Downstream) 1.8
Line Attenuation(Upstream) 26.8
Line Attenuation(Downstream) 46.0

Do you need anything else from stats ...and can you tell me where the errors are shown please?

I did a Freeola packet test: nil packet loss, Latency 40.423, Jitter 1

I got the BQM but that was 10-15 minutes ago and it's still blank ...ah! no it's not now ..there's a little bit of green and yellow on the right!
Do I paste the shared direct link ?

The best way to share the BQM is to put it in your sig. (In My Home, scroll to the bottom, Personal info etc.). Then it's always available. Easy enough to remove for the future once it has done what we want, but it can be useful to have around.

Yes you use the Direct Link, but neatest is to use the url tags to make it a standard named link like we do in the forums, rather than paste the raw stuff.

OK - pasted it into the Sig box ...hopefully I did that bit right

Yep, your bit of that is perfect. I can't say the same for the latency . Though it is fairly steady. Mine is all over the place from 8pm. I need to ask about that as it had a spell last week doing similar, and it shouldn't.

Thanks - glad you know what you're looking at. I'm not sure what's 'normal' on something like that.

Do you know where I'd find the error count on my router please? Can't say I've ever found it anywhere.

my comment is this.

higher latency will slow down things like dns lookups and image heavy websites as it lengthens the time for connections to be established, it also can slow things down if insufficient buffer windows are set for TCP although for modern operating systems it shouldnt be an issue on downloading as it auto tunes.

However for the connection establishing speeds its in order of milliseconds not seconds, I wouldnt expect that to be a noticeable affect on dns lookups just slightly noticeable when loading websites.

You have a very low noise margin but also looks like interleaving 'may' be applied on the line as well. Or you just have a long route to london.

Yes, interleaving appeared last June and the noise margin got re-set in early November.

Ack! Mea culpa.

Sorry re your BQM link which I said was correct, it seems you have the "Snapshot" one. It needs to be the "Share Live Graph" one.

OK.... this looks promising?

Error Seconds (ES) and S(erious)ES are high for 57 days Uptime on Interleaved. Is that when it last re-synced, when you rebooted router?

You'd probably be better off on 6dB NM.

Yes, that's the last time it was re-booted - actually unplugged it for a few minutes the day before at the Tech chaps request, but saw next morning that it had lost sync during the night and it's been re-connected at that ever since ...and that's the same day the NM was re-set according the the line data.

I'm pretty sure it never got re-set before and must have been at 6dB.

In reply to a post by TrishaH:

Yes, that's the right link, as you posted just after 2pm and it is now showing up to 3pm. Just wrap it in url tags now for neatness. You can do that by inserting them in your sig setup.

Looks good so far, very little packet loss showing. Latency reasonably steady, assuming you were doing stuff where those spikes were?

I'll look at the stats in a bit.

Must have got the url bit wrong because it disappeared so I had to put it back as it was. Edit: ian72 kindly showed me how to do that, so done now

Yes, was doing stuff during the spikes ...the longest one late last night was when I checked the router stats just before turning the computer off, and it was one of those that took a few seconds to open.

Edited by deleted (Thu 03-Jan-13 16:28:02)

Copy this but remove the dash before the word url in the opening tag and after url in the closing tag:

[-url=http://www.thinkbroadband.com/ping/share/315fccf9482d40ee613317b082c9efa6.html]link[/url-]

Will result in this:

link

Thank you!

You're welcome. You can of course change the "link" to whatever you want to call it and put some pretty words around it...

The funny thing is that with the wrong link you did the url bit perfectly . You can now edit the word "link" in your sig to "BQM", like you had originally.

There is an easier way:

If you put the (noparse) and (/noparse) tags around any of the bbcode (using brackets rather than parentheses, obviously), it will be treated as simple text and not acted upon.

eg your link example would become

[url=http://www.thinkbroadband.com/ping/share/315fccf9482d40ee613317b082c9efa6.html]link[/url]

and this bolded, italic underlined text would become [b]bolded[/b], [i]italic[/i] [u]underlined[/u]

If you see some effect and wonder how it was done, clicking the "quote" button will show all the gory details

Okeydokey

...and thanks all three of you for that help!

Hehe!

So now we'll know what time you go to bed and get up each day ....

ROFL - Couldn't resist that .

More seriously, that is still looking very clean but who know what might show up now and then.

Ha-ha! Well, the government seems to know everything we do, so why not! ...just don't tell me there's a webcam incorporated: first hour awake and I'm a bit of a zombie!
....so now 'broadband brother' is watching

I had to adjust my work & sleep time when husband retired - need at least a good few hours of concentration with work, so night is quietest - still need 7-8 hours sleep though!

I did notice that the graph seems to be slightly off timewise though - I didn't switch the computer on until at least 10.30am and I checked the router later than 2am. Still, it's accurate enough for purpose I suppose.

Connection been working not too badly today, but it does that and then gets iffy again.

I had assumed you got up a bit before the BQM activity started, in order to fix your makeup before coming on here. Your nail-varnish could do with a bit of attention however.

The timescale can be wonky for the first 24 hours. Then it knows where it is. I still haven't looked at the stats - forgot! Now have to empty the dishwasher - we need the space!

I do: up at 10am ...no choice as husband sends the dogs up to wake me gently - one is 58lbs!! Slurp!
Gave up on makeup when I jumped off the 'real job' treadmill in '89, as for nail varnish- sorry I'll try and present myself better tomorrow! (turps, resins and nail varnish don't mix well to be honest though).

My dishwasher is super efficient ..puts everything away when dried!

Tie a lump of string round your finger to remember to look at the stats ...think Uilebheist has a big ball of it for amnesia

In reply to a post by RobertoS:

Well, the connection seems to have been quite steady and responsive this past couple of days particularly.
For someone who doesn't need more speed, I reckon it's probably stable enough not to justify any extra monthly outlay for FTTC.

All I ask really is a responsive and sound connection with a reasonable speed for my needs.

I look at the NM's every now and then, and this is how it's been Down/Up since 18th Dec (much the same since 7th Nov when NM was re-set):

18/12 02.30am 2.3/5.9
18/12 11.00am 2.9/5.9
19/12 02.00am 2.1/5.9
21/12 01.30am 1.9/6.0
23/12 13.00pm 3.1/6.0
26/12 01.00am 0.8/5.8
27/12 01.15am 1.4/5.8
27/12 14.00pm 2.6/6.0
28/12 11.00am 2.9/5.8
31/12 13.00pm 2.9/6.0
03/01 02.42am 2.1/5.9
03/01 10.50am 3.0/5.4
03/01 16.55pm 2.4/5.8
04/01 01.45am 1.9/5.9
05/01 01.48am 1.2/5.8
06/01 10.40am 3.1/5.9

XRaySpecS advised asking for the NM to be re-set at 6dB - always the chance it'll start misbehaving again if they do I suppose, but when - and I think it will happen - it starts the slow loading of pages etc again, I'll ask them to try it.
Not sure if the interleaving from last June fixed anything amiss or made things worse!

From what I can understand, the BQM has shown very little packet loss ?

Just happened to notice that the ADSL dropped very briefly at 18.26pm - 3 minutes after it happend I saw that the downstream is slightly lower, but the up moreso:

There's no line data changes as yet on the ISP's customer section.

Should I pull the plug on the router for a few minutes in the morning and re-connnect to see what happens?

I think I would.

From those stats compared to the ones a while back, I would think something hit the upstream frequencies. Note the downstream and upstream noise margin changes.

If the noise was still there during the re-sync, which is quite possible, the noise margin would rise when the noise stopped.

I'll do that in the morning.

My mistake by the way - it had been down 3 hours earlier (misread 3 hours for minutes!)

The BQM showed a bit more blue this past day or two but not a lot.

As long as he isn't grinding animal bones you should be safe.

Duh! ...bench grinder ...and both dogs still intact.

Just thought that may have caused the interference.

I'd forgotten about the dogs. I wasn't thinking about those at all. I'm sure he wouldn't harm them. Beef ribs and lamb knucklebones were the sort of thing on my mind.

[ghoul] Think about it [/ghoul].

Aye we can. We can set the Target to 6db and a Stable profile which will stop ot from hitting 3db.

PM the details and I'll have this done for you.

Since the early discussion of the OP's problem the line concerned seems to have largely stabilised, on the 3dB setting. But it's good for the OP to know you can do this if necessary .

Close to the line any power tool is likely to cause some noise - the very nature of an electric motor means there will be wideband RFI, most significant at switch on, but will continue as the motor runs.

Many years back, we had a small hand held motor specifically designed to create "noise" and was used for testing immunity to interference. If I was to put one close to street cabinet it would probably create enough noise to make every line unusable.

Haven't been able to read any of these messages until now.
After hours of hoping to get it to re-connect, I called the Tech services, a short while ago, spoke to Sherrif who was very helpful, and he did indeed decide to re-set the SNR and put it on Stable profile
Very happy now as it's synced at what it was before Nov 7th and the latency has gone back down too.

Seems it was teetering on the brink when I first asked the original question of this thread last week! ...and it's lookiing like they were spot on!

As you can see, it gave up this morning, and hopefully it's fixed now
These are the stats just a few minutes after the margin was re-set etc:

DMT Status No Defect
Operational Mode ADSL2+
Upstream 1080
Downstream 8107
SNR Margin(Upstream) 5.4
SNR Margin(Downstream) 6.1
Line Attenuation(Upstream) 26.6
Line Attenuation(Downstream) 45.5

Looks pretty much as it used to before early November, and was a really stable connection until then.

Websites now seem to be loading as fast as they used to, and emails downloading properly again! Happy

Amazing what seemingly innocuous electrical items can cause problems!

Guess I won't bin his grinder now!

Makes my reply to Azzaka look a little premature, .

No, not at all - you said it how it was: OK ...which is as it was last week just about.

Seems any problems I've had were likely down to the DLM 'fixing' something that wasn't particularly broken last November - which is what a number of you correctly suspected: noise margin.

It seems happy with itself now anyway: SNR Margin(Upstream) 4.7
SNR Margin(Downstream) 5.2

Hopefully, all will be well now.

Hey!

Have you looked at your BQM? Look at the latency!

Ahh ..it's good to see it back to 'normal'

ADSL dropped briefly at 12.35pm this afternoon (12th) - when I checked, the latency had gone back up again! It also synced slightly differently, but not much.

I asked ISP if the DLM had put it back on interleaved, and he said it didn't appear so.
He set up something called a ping monitor and said to call back on Monday to see if they saw any reason.

SNR seems to be still OK - router currently at 2am:
Upstream 1091
Downstream 8317
SNR Margin(Upstream) 6.3
SNR Margin(Downstream) 5.1

So, I'll see what's said on Monday.

The BQM showed a steady connection with very small blue spikes and no packet loss for two days.
I did however have the problems with emails downloading into Outlook in a timely fashion for those two days. (Had this last summer for a time), plus some websites hesitated to load.

Spoke to ISP last night and they agreed that despite the latency going back up on Saturday after it lost sync, all seemed well.
I again mentioned that I'd thought interleaving had been reintroduced.
This morning, most of the BQM was black, but activity since 9.30am shows packet loss and a bit more spikiness on the average latency.

I just checked the line data, and it's been updated since yesterday, and see I was right about why the latency went back up on Saturday - the interleaving did come back on!

I know these aren't big problems, but until June I had a decent connection with no problems of slow downloading emails and web pages, and was always on 'Fast' Run mode.

Your black was because the BQM was broken. So that's nothing to worry about .
