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

Question:
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…?

Answers:
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...

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 to get the ADSL signal upstairs to your modem/router.
Answers:
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...?

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.
Answers:
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
Answers:
Yes that it what I suggested in my first reply
Answers:
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...
Answers:
Have you tried it with no extension lead? i.e. modem into master socket.
Answers:
No unfortunately I haven't tried this. I'd have to move the PC downstairs to try this as there's no phone socket upstairs. Though if I was using the ADSL extension cable (which you linked to above) then this would mean I would be connecting the modem direct to the master socket
Answers:
The reason that I asked is because you are having problems, do you know that the line is actually ADSL enabled?
Answers:
I just typed my telephone number and postcode into and it states that the line is ADSL enabled.
Answers:
I just tried it again, with the extension cable plugged directly into the hall socket (no microfilter), then at the end of the extension there is a microfilter and the modem plugged into the ADSL/modem part of the microfilter.
This time it did actually connect to the homepage so there is some connection! But unfortunately when I clicked on any links it would not connect to these, or when I typed an address in to the address bar it would not connect either. Maybe this is because the telephone extension cable is not good quality...
Also the microfilter is this type...
and not the more expensive "soap on a rope" style...

Answers:
after you have connected, post the results of a
start, run, cmd
ipconfig /all> c:\1.txt
notepad c:\1.txt
to check whether your dns servers are ok.
also try ping
and
ping 64.233.183.99
if both pings say reply from ... , then you are connected to the net.
Answers:
Yes I have TalkTalk broadband
I checked the new link, typed in my telephone number and it states..."This line has ADSL fully installed on it. There are no open orders currently on this line."
I have just went to: start, run, cmd, and typed in...
typed in ping 64.233.183.99
it states..."Destination net unreachable"
Answers:
It may be that your homepage was cached (your computer had a copy of it stored, so it appeared to load), but you didn't have an actual connection.
When you say you typed your number in the broadband checker, have you actually got in touch with a broadband ISP and ordered broadband? Sometimes its the first steps that can get missed. If you haven't done this part its like complaining you don't get water out your tap when its been turned off at the mains.
Usually after ordering it takes about 10 days to set up your broadband (BT have to go out and activate it, the checker just ensures that BT have equipment capable of broadband at your exchange, not that they have got it running).

This may be a better one..
