20 internet disconnections a day

sparkler · Jun 12, 2012, 08:09:11

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

ValleyBoy · Jun 12, 2012, 08:21:07

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.

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 · Jun 12, 2012, 10:45:44

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

sparkler · Jun 12, 2012, 11:05:43

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 · Jun 12, 2012, 12:01:40

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 · Jun 12, 2012, 14:03:41

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 · Jun 12, 2012, 21:39:09

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 · Jun 12, 2012, 22:38:42

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 · Jun 13, 2012, 06:32:58

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

davej99 · Jun 13, 2012, 07:06:03

14 disconnects for me with no loss of sync.
Dissconnects from 19:17 12-6-12 to 06:03 13-6-3.
WAN/LAN uptime to 06:03 was 23:34 hours.

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

Gary · Jun 13, 2012, 07:50:22

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

Glenn · Jun 13, 2012, 08:00:12

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.

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:

QuoteWed 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.

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 · Jun 13, 2012, 10:00:59

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

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 · Jun 13, 2012, 10:12:24

Perthshire's a good compensation.

sparkler · Jun 13, 2012, 11:06:23

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 · Jun 14, 2012, 10:28:59

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.
