End of 2012 I treated the house to a brand new landline. Didn't fix the problem.
I was also moved to EE Broadband (from Orange) but this didn't make any difference.
Over the last few weeks the problem's been getting particularly bad - just dropping out once every two hours or so. Picking up the phone, dialling 17070 #2 and fiddling with the wires around the master box seemed to get a connection back for a while, then it'd drop out again. There would sometimes be very bad noise on the line, othertimes not, and sometimes when I picked up the phone, I could very faintly hear that siren noise you get if you leave your phone off the hook for a minute or two. Is this intrusion from a neighbour's line????
Anyway I got sick of this so I purchased a brand new Asus DSL-N55U router to replace my Belkin one which wasn't supported any more and would occasionally lock up. Didn't fix the problem.
So I purchased 15 metres of brand new RJ11 cable and ran it from the master socket (along with the new filter that came with the ASUS) up the stairs and into the new router.
...in that it's not dropped out one single time over a week. This doesn't sound like a very long time to give it but I'd have had a dozen drop-outs by now with my old setup. I think that the old cabling was too long (it went outside the house, up through into the attic, through an extension socket and then down into the bedroom and went through a long coil at some point so it must have been at least 30 metres long), or just poorly somewhere along the line. I had visually inspected what I could of it and it looked ok. Perhaps it wasn't.
Anyway hopefully it's sorted now...!
PS Even though it appears to be sorted, sometimes when I answer a call on the landline there's very loud crackling on the line. Wonder what this is?
