I have no other equipment connected to the phone line.
Can anyone suggest a course of action.
Thanks

I've just carried out some testing on your line I've not been able to spot anything remotely. Does the crackling only start once the router is powered up or is it still there when there's just a phone connected?

The noise on the line does not start when the router is powered up but when it is connecting to the DSL line and with the DSL line flashing. (Sorry if I wasn't clear on this)

Is the phone DECT or wired?
Is the phone using the same socket / filter as the router? If separate, both phone and router must be plugged into filters.
Are the two (or more) filters identical? Have they both been used previously? Note they could both / all be defective.
I sometimes can hear very faint modem noises on the phone line, but not something matching what you describe.

I have tried both a DECT phone and a wired phone into the main socket with the same result.
Phone and router are both plugged into the same filter/socket.
I have substituted a new Belkin filter for 2 other unbranded filters with the same result

Out of curiosity, I have just tried a broadband speed test and found it to be very slow, <1Mb. I used to get close to 6Mb. Is this related?

I had already tried a different RJ11 cable.
I bought a new Belkin filter to replace the unbranded one.
I have also double filtered the phone.
None of these actions has had any effect.
Do you think that the router disconnection(s) and slow broadband simply coincidental?

Can you please gather the information requested in the speed issues thread at the top of the broadband forum?
