Frequent disconnections

Go to solution

My broadband keeps disconnecting at random times. It disconnects up to 20 times a day and on Wednesday morning was down for about 5 hours. I rang BT and an engineer was supposed to come around on Friday but phoned on Friday afternoon to cancel, now will not come till Wednesday morning. I have tried plugging in to the test socket and also tried 2 different Homehubs plus a BT business hub but all suffer the same problems. I have also changed the filters. Previous to these problems the router would stay connected for days.

Update,
An engineer called on Sunday morning. He did some line checks and changed the master socket and also checked the extension wiring.
He said that the line was now stable!
Unfortunately the problem still remains and the router as lost sync 12 times in the 7 hours since he left.
I rang BT wholesale again on Monday and arranged another engineer visit for Tuesday morning.
Latest update.
Engineer never showed up and no call to let us know he wasn't coming.
Rang BT wholesale who are now trying to chase up what as happened.
He did say that a note had been left on our account but I've no idea what the note was.
The disconnections continue and I'm now getting a bit angry at the service I am receiving.
Two failed visits, waiting in for no one to show is very frustrating.
Latest log of disconnections.

How goes it Red? ... hope your ok.

 

Does quiet line test pick up any noise?

 

17070 option 2,

 

A radio tuned to 612MW will show potential rein problems...

 

Gather your still using the old business router?

Re: Frequent disconnections

Hi Roger.

The quiet line test just had a slight hiss.

As for the radio that station is the best I've tuned in to.

Here's the playlist,

 

"Don't Speak" by No Doubt.

"Enjoy the Silence" by Depeche Mode

 Bjork - "It's oh so quiet

 Coldplay, "A Whisper"

Smiley Happy

 

Just a gentle hiss even with the volume full up.

 

Going to try plugging it into the test socket again later but don't think it will make any difference.

Margins at 15db

Drops at anytime during the day or night.

The router is showing lots of errors as well.

Re: Frequent disconnections

Like it was before BTw fixed the margin below threshold in April maybe?

 

Looks like your deffo under line management again.

 

If all's well at home, as you said before (April) ....

 

I reckon you may be looking at a pairs change matey.  😉

 

Looks and sounds like an HR line fault to me, and even the Openreach guys will admit they;re not easy to find.

 

You might get lucky with a pairs change though .....

Re: Frequent disconnections

Cheers Roger.

The IP Profile is up and down as well.

Down to 1700 yesterday as I would expect with all the dropouts.

Back up to 3500 today, not what I'd expect with all the dropouts.

Latest speed test result below.

The assured rate test looks a bit odd.

 

 

Test1 comprises of two tests

1. Best Effort Test: -provides background information.

 For your connection, the acceptable range of speeds is 600-7150 Kbps.
 Additional Information:
 Your DSL Connection Rate :4384 Kbps(DOWN-STREAM), 448 Kbps(UP-STREAM)
 IP Profile for your line is - 3500 Kbps

2. Assured Rate Test: -provides background information.

Re: Frequent disconnections

Go to solution

As a matter of interest, have you got another router to try?

 

(not that it'd make much difference where line faults are concerned, but it would discount the old router firmware)

 

I did wonder whether "your fixed settings" had been over-ridden by dslam/msan software upgrades, to do with changes in the network (21cn and stuff).

 

(Deep thoughts only, no evidence to support, thinking out loud really )

Re: Frequent disconnections

Have already tried 2 Bt Homehubs. Both V2 type A but they both kept disconnecting.

I know there not great but there the only other routers I've got.

 

My exchange as no date for 21cn.

Re: Frequent disconnections

Plugged the router back into the test socket. Will monitor overnight and feed back. Don't look good though as it dropped the connection within 10 mins.
