ADSL Connection and cable problems.

[xxxPeanutxxx]

Hi Guys, I really hope you can help as I'm a little stumped with this one.

Background: For the past year or so whenever the house phone rings there's a chance it cuts us off. It never used to happen, but now there's a lot of noise on the housephone line (crackling) and it's just got steadily worse. At first it was only if the house phone was answered. Now it's if it rings at all, whether answered or not. It doesn't cut off every time, but at least half the time. (also disconnects for no apparent reason where it used to be quite stable.)

House Wiring: Now the master socket is not just a single phone socket with a microfilter plugged in. It has a microfilter built in. phone socket on one side, RJ45 connection on the other. (EDIT: Reading another thread, this seems to be a Filtered Faceplate.) The RJ45 cable plugged in runs upstairs and ends in a wallsocket with an rj11 connection, which the router plugs into. And when I say it ends in wallsocket I don't mean it's plugged into it, I mean on the end of the cable, rather than an rj45 connector or rj11 connecter it actually has a wallsocket on the end which is attached to the wall.

Still with me I hope. We keep ringing BT to sort it out but they say we need to change the microfilter before they do anything, but we can't as it's attached to the wall. Unscrewing the whole wallsocket leaves a single phone socket there, but when we plug a microfilter into it, the microfilter only has an RJ11 socket for the internet. Where as the cable that runs upstairs needs to plug into an RJ45. Now you can't seem to buy rj45 to rj11 adapters as one is normally analogue and the other digital, but it somehow doesn't make sense to me as you can buy cables that have RJ11 on one end and RJ45 on the other. But nowhere sells adapters that I can find.

Sorry, for the large walls of text but I want you to have all the info you need.

Now, what's the best thing to do? Do I need an engineer to come in and rewire everything which may cost a fortune which I don't have?

Is there something else I can do? Do you need more info?

The router ideally needs to be upstairs as that's where my PC is. Only the laptop is used downstairs and that connects wirelessly. My PC is hardwired to it.

I live in the UK, the router is a vigor2800g, I have 8mb adsl2, though I barely get 2mb speed on it normally, and speed tests show I have a maximum of 3 which living in the middle of a major city seems a little low? Then again that could be normal, I'm not sure.

right, firstly, that filtered faceplate sounds a bit didgy to me, as it should have an rj11 socket on it for broadband, not rj45!

if this was the case, then you wouldnt be having problems.

i suggest that you move the router to the phone socket so you can test it with another filter as you described.
