Connection and reconnection frequency

dbr — Tue, 04 May 2021 20:11:12 GMT

Hi,

I've been looking through my router logs and have come across the following where the DSL line keeps dropping and reconnecting quite reguarly - many times per day. Is this normal to do this?

That is not normal and there is a problem with that many resets

Try quiet line test dial 17070 option 2 should be silent and best with corded phone preferably from test socket

Hi @dbr and welcome back.

It's been a while but it's great to see you again. Can you try the quiet line test mentioned by @imjolly and let us know how it goes?

Cheers

David

Hello guys,

Thanks for your replies.

The first time I did the test, I got something about a entering a mobile number to receive SMS results from and did not do anything so I hung up.

The second time I tried it I got a quiet line apart from the periodic voice over telling me this was a quiet line test so I guess all is well there???

Re: Connection and reconnection frequency

imjolly — Wed, 05 May 2021 20:27:31 GMT

As long as quiet line test was totally silent apart from announcement - no hiss, crackle, etch

Have you tried using the test socket with a filter to see if that helps the hub stability?

Re: Connection and reconnection frequency

I have a Master Socket 5C which the router is plugged in to.

I believe this is filtered already?

Re: Connection and reconnection frequency

pippincp — Fri, 07 May 2021 19:02:03 GMT

Yes, the master socket is prefiltered but the test socket isn't.

Re: Connection and reconnection frequency

imjolly — Fri, 07 May 2021 20:54:37 GMT

Which master socket do you have

Re: Connection and reconnection frequency

dbr — Sun, 09 May 2021 18:05:06 GMT

Hi,

I have socket number 7.

Re: Connection and reconnection frequency

Keith_Beddoe — Sun, 09 May 2021 18:42:49 GMT

@dbr

That master socket is known to give problems, and is most likely the cause of your disconnections.

As mentioned https://community.bt.com/t5/Landline/2019-Master-Socket-kit-loose/m-p/1985566#M6775

You need to connect things up as shown below, and see if you still get disconnections. Leave it like that for a few days.

NTE 5C Test socket check

Re: Connection and reconnection frequency

dbr — Tue, 25 May 2021 20:12:24 GMT

Ok, so may have had some success, maybe???

I did as @Keith_Beddoe suggested by adding a micro filter to the master test socket on 14th May and until today, the logs look like there were no reconnection events until today:

03:58:10 25 May. DSL Link Up: Down Rate=113897kbps
03:58:02 25 May. WAN Auto-sensing detected port DSL WAN
03:56:17 25 May. WAN Auto-sensing last connection port: DSL WAN

00:29:00 30 Apr. DSL Link Up: Down Rate=128376kbps
00:28:52 30 Apr. WAN Auto-sensing detected port DSL WAN
00:27:18 30 Apr. DSL Link Down: duration was 106176 seconds
18:57:50 28 Apr. DSL Link Up: Down Rate=118439kbps
18:57:43 28 Apr. WAN Auto-sensing detected port DSL WAN
18:55:57 28 Apr. WAN Auto-sensing last connection port: DSL WAN
01:08:55 28 Apr. DSL Link Up: Down Rate=121860kbps

not sure how many or what frequency this is supposed to happen? You might well consider that it would try to renegotiate a higher speed periodically or refresh the connection maybe but for whatever reason is this plausible to happen periodically (albeit not at the frequency it was happening)???

If by adding the micro filter as indicated has solved the problem, do I get myself another one of these master sockets or is there a better alternative?

Thanks

imjolly — Tue, 25 May 2021 20:19:39 GMT

As disconnections appear to have reduced by using a filter then that suggests either a problem with master faceplate or internal wiring or both. You could replace master faceplate and disconnect and internal extension wiring
