What extension/microfilter set-up needed if telephone socket downstairs and PC isn't?

Becca

The telephone socket is in the ground-floor hall. The PC and *also* the telephone is located on the first floor, so I have placed a microfilter adapter into the telephone socket in the hall and I have *one* extension telephone cable running from the hall socket up to the first floor.

Into the telephone socket, which is at the end of the extension telephone cable on the first floor, I then have another microfilter here in this. I then have the telephone plugged into this in the “phone” socket of the microfilter, and the modem plugged into the “modem” socket of the same microfilter.

I haven’t been able to get the broadband connection working, but maybe what I should have done is to plug a cable into the “ADSL” socket of the microfilter in the *hall* and bring this own separate cable straight up to the modem on the first floor and plug this directly into the modem…

Which would mean there would be two cables travelling from the hall socket upstairs. One going directly from the microfilter in the hall up to the telephone and the other going from the same microfilter and up directly to the modem.

I wonder if this is what’s wrong…?
:huh:

I don't think it matters which way you do it, but you only need 1 microfilter, i.e put the microfilter in the end of your extension.

Thanks derrick, I was told by the broadband supplier that I would need a microfilter for every socket/connection in the extension both at the main telephone socket in the hall and also at the end of the extension cable.

If you put a filter into the hall socket and then plug the extension to upstairs into this, you will be preventing the ADSL signal from getting upstairs to your modem.

Thanks, yes this is what I was thinking might happen. The broadband supplier just said I should have a microfilter in the hall and also at the end of the extension, but as you say if I do this and place a microfilter in the hall then the signal will not get upstairs to the modem.

So if I did put a microfilter in the hall then I definitely would need a separate cable from the ADSL part of the microfilter in the hall and going upstairs *directly* into the modem...

To make it clear for anyone, every device must be plugged into the correct side of a microfilter.
You should only have one filter between each device and the BT line.
(You can have two or more phones into one filter using an adaptor)
Don't forget that most Sky boxes need a filter, too, and they go into the telephone side.

edit - Yes, Becca, you're right, so don't, just put a filter in upstairs

Yes if you need a filter downstairs in the hall to enable you to use a phone there, you could then use an ADSL extension cable like this to get the ADSL signal upstairs to your modem/router.

Becca

Thanks for the link, yes that's just what I would need.

I wonder if the setup would also work if I had the telephone extension cable coming from the telephone socket in the hall (with *no* microfilter in the hall), travelling upstairs and then only at the end of this extension cable having a microfilter plugged in here. With the telephone plugged into the phone part of the microfilter and the modem plugged directly into the ADSL part of the microfilter...?

derrick

Yes that it what I suggested in my first reply

Yes that should work OK as long as the quality of the extension cable is good enough. Ideally twisted pair telecoms cable should be used for best results and extension cables can cause problems with ADSL max sometimes depending on how far you are from the exchange. Using a proper ADSL extension cable may give you better results but the other way should work.

Becca

Just tried my suggestion as above, but unfortunately it doesn't seem to be working. Maybe the extension isn't good enough as it's just a regular telephone extension cable.

I'll purchase one of the ADSL extension cables which you linked to above and try this...
