Re: Connection and reconnection frequency

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???

imjolly · ‎05-05-2021

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?

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

I believe this is filtered already?

pippincp · ‎07-05-2021

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

imjolly · ‎07-05-2021

Which master socket do you have

Hi,

I have socket number 7.

Keith_Beddoe · ‎09-05-2021

@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.
