20 internet disconnections a day

[davej99]

My Netgear DGN2200 router is logging about 20 internet disconnections a day since 2-6-12. Period of disconnect is almost always exactly 14 seconds. More discons early hours but some daytime and evening. There is no associated loss of sync.

ADSL2+ line stats and profile are rock solid and as good as they have ever been. 40dB atten and a margin of about 6dB gives me a sync of typically 10Mbps and a profile of 9Mbps. Only one resync since 28-5-12 and that was to a higher rate. Hardly noticeable browsing. Don't P2P or schedule so would not notice.

Does not seem like a house loop or line problem because. I use a filtered master faceplate with a hard wired dedicated ADSL spur leading directly to the router. There is no associated resyncing or variation of noise margin on plots. Router could be faulty I guess.

Have mentioned the problem to Tech Support, who want me to test at the master socket. All my kit is about 15 yards away driven from a switch at the router end of the ADSL spur, but I suppose it will have to be done to keep everyone happy. 

Meantime would appreciate any ideas on the possible cause from our NetterGurus

Thanks and regards, Dave

Nothing makes obvious sense, Dave it sounds like a BT fault, but the test socket routine will protect you from BT's charges.

[davej99]

You are right, Rik, it will have to be done, but 20 yards of patch cable across the house overnight will not find favour with the boss. And the ADSL2+ switch over was going so well. How r u btw. I have not been around much for a while? Been in Wester Ross and Skye. God's own is glorious right now!

Having exactly the same issue, spoke to support Thursday who said they would check the line, never heard back from them though. Mine are anywhere from 10pm to 7am, all seems ok in the day and are very brief, like yours. My line stats have not changed now, although it dropped about 15 times last night, speed is the same, so is snr. Most odd.  Mine started exactly the same time too. Apart from lots of issues at Guildford BRAS mentioned on AAISP I have no idea what's causing this. Getting fed up of it though. It does not seem to resync, its more like a loss of Authentication.

Tell her it's good for the economy.

Jammy bugger.

I've not had a good year with the heart, Dave, and am waiting for treatment when I'm well enough, a certain irony there.  It's a bit dispiriting, but we'll get there.

[davej99]

Thanks, Gary. Glad to know I am not imagining things. I am in Perthshire, so I am not sure of routing. As luck would have it I was browsing during a recent interuption and the site failed to load. Windows showed a solid internet connection and Routerstats showed no break. I guess many users would not notice unless router logs were checked. I get them emailed daily because I am monitoring the connection since I moved to ADSL2+ in March, (21CN finally crept into my bit of Scotland). Cheers, Dave.

[davej99]

It's a bit dispiriting, but we'll get there.

Hang in there Rick. We Netters need you. My 60+ sis-in law just had a hole in the heart patched. It took about just over an hour and she was home next day but one. My 60+ bro-in-law has a chest like a row of Saltires because he has had so much heart surgery. He just had a pacemaker fitted as well and last week we did a path climb in Skye of about a 1000 feet.  So much can be done these days, here hoping all goes well. Dave

[Ardua]

Best wishes Rik. My good lady and I had a brilliant two weeks in the Western Isles a month ago. Sadly, Scottish Government may spend a lot on healthcare etc but in some parts nothing on their roads. It was also an Internet stress free fortnight. Free wifi often offered but rarely available. Time to think of other things like photos for my next album.

I tried a Netgear 2200 when I transferred to ADSL2+ a year or so ago. After one disconnect after another my downstream SNR rose to 15. Did all the tests and eventually I took the Netgear back and replaced it with a Fritz!Box. Disconnects stopped but my SNR stayed high for about 3 months before falling to 3 over a period of 3 months. Eventually, the line stabilised at 17.5Mbps down. Never really got to the know what caused the initial loss of synch problems.

I'm wondering fif its my router, a DGND3300, thing is I was up for 1000 hours or so since I last rbooted, and its so intermittent 

[Rik]

Thanks guys. 

[Technical Ben]

I'm getting the same. 

[sparkler]

ive been getting disconnects for over a week went nuts on Friday and net was virtually unusable i don't think this is a line fault but a deliberate attempt by bt to disrupt my internet connection so i go back to them as it looks like bt are repeatedly turning of my internet connection for a few mins then turning it on so i reconnect rather than interference

[Gary]

My line seems to be behaving at the moment  BT where seen with lots of cables at the greenbox at the end of my road, maybe thats what the issue was. Lets hope its all settled again now.

[sparkler]

my connection seems to have gone normal as well i can actually maintain a vpn connection

[davej99]

Looks like my problem has cleared. I have not seen any disconnects in the last 48 hours or so.

I was logging about 20 internet disconnections a day from 2-6-12  to 9-6-12. The period of each disconnect was almost always exactly 14 seconds. More disconnections early hours but some daytime and evening. No router red lights or sync blink. Line stats and profile rock solid throughout and as good as they have ever been.  No loss of sync or variation in noise margin seen on Router Stats plots when disconnections occurred. Pings 22ms to idnet.

I never heard back from support  I just told them they had stopped today.

[sparkler]

ok so 2 of us are in wales anyone else in wales or are the rest of you english??

and ive been without internet for 3 hours stupid auth fail message

[davej99]

Still OK here in sunny Perthshire. Pretty certain I was losing PPPoA not sync. Is that the case for the Welsh cases mentioned?

[sparkler]

ive been losing sync with the exchange as in noise margin 8db then 3db then -xxdb and gone

[ValleyBoy]

Left the PC on for quite a while last night and had no drop for over 7 hours kept checking! Powered the PC down and checked again this morning only to find that I had multiple drops overnight. It is really strange never seem to have a dropout whilst working on the PC in the evening, most disconnects appear to happen over night and during the day.

No loss of sync apparent.
Upstream 8128
Attenuation 28db
NM 6db

Downstream 448
Attenuation 8db
NM 24db

Been the above for over 18 months.

Going to replace the filters and all the cables this evening first, if no luck with that will replace the router (a little lucky in that respect as I work in IT so can borrow kit quite easily). If that fails then it would have to be something at the BT end, as I would have eliminated all internal factors.

The annoying thing is that I have had a rock solid connection for about 18 months, did have an exchange problem in January 2011.

[Rik]

That sounds local. Have you tried the router in the test socket?

[sparkler]

That sounds local. Have you tried the router in the test socket?

yes its local from router to local exchange and its in test socket but thats never done anything in the past

[Rik]

Try a new filter, borrow a router if you can.

[sparkler]

ive done that last time as well and it was no use even changed the cable

edit: ive got a Billion BiPAC 7800N coming tomorrow so everything from router to test socket wil be brand new and straight out of the box

[ValleyBoy]

Have a brand new filter, and rj11 cable and will plug directly into master socket...only thing I will not change at this time will be the router. If the new cable and new filter do not the trick then will try a new router. If all those fail will have to be BT.

Could be a master plan by BT to create problems at this time as the exchange gets upgraded to FTTC at the beginning of September.

My faith in BT is quite low ever since a couple of years ago I tried to report a problem (automated service) with the Telephone being constantly engaged. The automated service said one minute while we test the line! the automated reply came back.....sorry we cannot test the line at this time as it is engaged, please ring back later! That was the fault I was trying to tell them about! Ended up in this constant loop until after multiple attempts actually got to speak to somebody in person.

[Rik]

My faith in BT is permanently low.

BT are in a league of their own.

If you are sure you are not losing sync, it is hard to believe the problem is the filter, house loop, or the line up to the exchange MSAN. In my case I did try another router, which was fine. But when I reverted to the original one, that was fine too. Mistake I made was not to power reboot the original router first.

I read BT are trialing low power mode ADSL2+, whereby power reduces when connection traffic is low. (It's called BT Cool Broadband, which I do not understand). They say this allows a line that is not being used, to drop down in power and reduce its bit carrying capacity. When more data is demanded than the low power mode will carry, the line will request the transition back to the previous full power rate. BT say in order to support the low power mode, both ends of the circuit require low power mode, MSAN & CPE. Whether the latter is ISP or subscriber equipment I do not know. They call it an always available rather than an always on service. I wonder if this is somehow to blame as circuits that should not try to go to sleep.

[ValleyBoy]

Changed the cable to the router. Router plugged directly into BT master socket and changed the filter.

Been steady for over 4 hours but have now noticed that the noise margin is fluctuating between 6db and 3db 

Next option has to be the router.....if that fails then definitely something wrong somewhere...done all I can to eliminate potential causes.

[Ruerin]

No disconnections for me, but certainly some strange routing issues. I've had ~200 ping to Moscow and ~160 ping to New York today (certain gameservers only). A friend of mine on BT has been having it a lot worse, though - constant disconnections every 5 minutes.

[Steve]

Someone had a busy night. BT connections seemed to be down in the early hours for several if not all of us.

[davej99]

My faith in BT is permanently low. 

you should try talktalk bt won't seem so bad then

[Gary]

Down for me at about 3am, no loss of speed, just authentication once again....

[Glenn]

From the admins's TBB graphs, it looks like all BT lines had downtime last night, twice for Zap. Rik's LLU connection remained unaffected.

[zappaDPJ]

Someone had a busy night. BT connections seemed to be down in the early hours for several if not all of us.

I lost the net at 00.10am and didn't get it back until 4.30am. I took a forum off-line at midnight to apply what should have been a quick security patch, started uploading the files and down it went. I've just finished clearing up the mess. Night night

I've just found this on BT's site:

Wed 13/06/2012 at 00:14   Ongoing    We are currently improving the broadband network   

More details

Estimated time to resolve: 2hrs
We are currently improving the broadband network. This may cause you to experience a temporary loss of service. If you are having problems connecting we apologise, please switch off your equipment, wait three minutes before switching on your router, restart your computer and try to reconnect.
If you have already tried this and are still having problems, residential customers can call 0800 111 4567 or business customers can call 0845 600 7020.

Seeing as this was quite obviously planned, it's a bloody disgrace that there was no prior notification to ISPs/customers.

[davej99]

.... it's a bloody disgrace that there was no prior notification to ISPs/customers.

Meantime, I reconfigured to run my router from the master socket in readyness for testing. Now the house phone is causing loss of sync and my profile is trashed. After all it seems evident BT is causing the original loss of connection problem.

I should have stuck to my belief that a dedicated hard wired ADSL spur from a filtered placeplate is always going to be more robust than a dongle filter and left things as they were. Testing at the master socket is clearly not a good idea if there is no evidence of a sync problem. But BT think we are all dummies, so customers and tech support can get nowhere without this often pointless routine. (Rant over)

PEWs overan here, but I got a better sync speed, up and down, out of it.

[Gary]

What confuses me is why other ISP's don't seem to go down, phoned a friend in the village on talk talk  and his logs show no downtime last night, which is pretty amazing considering its talk talk 

[davej99]

....  phoned a friend in the village on talk talk and his logs show no downtime last night ....

If talk talk are using LLU in the above case, your friend may be unaffected. Have to say Sky and TT are options for me to avoid BT. Wish IDNET could persuade BE to expand their LLU in Perthshire. 

[Rik]

Perthshire's a good compensation.

[sparkler]

ok ive got my new router i like it better than my old dgn2000 as its firewall actually works also got 300mbps instead of 270mbps wireless

[davej99]

Disconnect problem seems to come and go. There yesterday, gone today. So far as I can tell, these are multiple 14 second PPPoA interupts with no loss of sync. Have played about with filters and routers and master socket test point, but that seems to create noise not reduce it. James in Tech Support has been testing stuff, (thanks, James), and my circuit looks fine. So I guess it is down to BT pratting about. Would advise others with this problem not to tinker with setup if there is no loss of sync.

[davej99]

Nope adsl not LLU. Anyway my lines stable again for a day, really fed up with this, especially since no one has any idea what when and why. Makes me laugh my line has been stable for three years since I moved here, BT do work to make things more stable and now its shot to hell

Has anyone contacted support?

I did, but during the time they had not got around to testing my line (I called, they said they would test my line)  it had stopped again so I emailed them to let them know. If I call today and they say they will test my line, by the time they won't have it will be fine again. 

[sparkler]

i contacted support anyways internets still screwed up and is really pissing me off might even return to bt atleast that way they will stop disrupting my internet connection

Not being with BT is also not the cause of your issues,  BT Wholesale is nothing to do with BT who sell you BB. On a side note mine glitched at 16:24. God knows what's going on but I'm more than fed up now.

[sparkler]

well i never had these repeated disconnects until i left bt then a week or 2 it started so its got to be bt i doubt my line got upset that i changed suppliers and started messing my connection up on its own also openreach is a bt subsidiary

BT do not hunt people down and mess with their line, sadly you are not that important to them in the grand scheme of things.  The issue seems to be elsewhere and only effecting some lines, mine was rock solid for years, now I get these glitches where I loose sync but it does not effect speed or snr.

[sparkler]

well my snr is lick i yoyo speed is also messed up probably because i disconnect all the time

[Tacitus]

i doubt my line got upset that i changed suppliers and started messing my connection up on its own........

You weren't moved from ADSL to ADSL2/2+ in the transition were you?  The reason I ask is that my sister has recently been moved across although she's still on G-DMT.  However her once stable line now repeatedly disconnects and drops speed from its once solid 5500/6000 to as low as 192.

The only other reason I can think of is that she's suddenly been subject to some major noise events, to which ADSL2 seems more sensitive.

Fortunately she has the option of fibre, although that would probably mean leaving iDNet.

[cavillas]

I believe that BT equipment failures causing outages in Sheffield and London are still causing problems throughout the country even now.

[sparkler]

nope only adsl adsl2 is coming sometime this year the date keeps changing also have to restart my router a few times as my wireless is acting funny

[Tacitus]

I believe that BT equipment failures causing outages in Sheffield and London are still causing problems throughout the country even now.

She's in the East Midlands Alf, so she's quite possibly being affected by the failures in Sheffield.

[sparkler]

ive switched to G.lite mode lets see if that works alo my internet speed has halved with it :/
