What extension/microfilter set-up do I need...?

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

The first filter in the hall is filtering out your adsl signal. Just get rid of it and plug your extension lead straight into the downstairs socket.

Double phone adapter in the hall socket.
one side has a filter into which you plug your hall telephone. The extension lead plugs into the other half of the adapter. Fit another filter for your pc and phone at the other end of your extension lead.

I've tried that setup Motto but it doesn't seem to be working so was thinking maybe I'd just connect a RJ11 to RJ11 Cable (ADSL Extension lead) such as this one...

directly into the ADSLpart of the microfilter in the hall and have this travelling upstairs and going directly into the modem.

Follow these instructions; I have the use of a modem/router, a dial-up modem and a telephone, connected with a 15 metre BT extension lead. It all works just fine.

DOWNSTAIRS
- Doubler in BT Master socket.
- ADSL microfilter in one side of doubler.
- Telephone in telephone socket of ADSL microfilter, The ADSL side left empty.
- BT extension lead in other side of doubler going upstairs.

UPSTAIRS (or other rooms)
- ADSL microfilter plugged into end of BT extension lead.
- Broadband modem/router plugged into ADSL side of ADSL microfilter.
- Telephone plugged into telephone socket of ADSL microfilter. (With the use of another doubler I also have a dial-up modem connected into this socket)

IMPORTANT microfilters must be fitted to all telephone extension points in use.

I use the soap-on-a-rope type of ADSL microfilters. XF-1e Professional ADSL2/2+ Microfilter is my choice for top quality! The very cheap microfilters can let you down. (Read the reviews)

ADSL Nation XF-1e Professional ADSL2/2+ Microfilters, the lowest prices I have seen.

That would work, but you really shouldn't need to. E7er's post is saying the same thing. If you have a downstairs phone as well as upstairs, use their method. If not use mine.

As long as your extension cable is not plugged into a filter your adsl signal should travel upstairs without the need for a second line. Unless, of course, you've got a faulty line or filter.

DSLZoneuk used to have a little digram to help, but their site's borked atm.

Think we need to start at the beginning and check your ADSL works downstairs. It wouldn't be the first time BT enabled the wrong line.

Thanks E7er - I've just tried that setup which you described, and yes it is now linking to the homepage so I have some connection...but it is quite slow and when I click on a link it won't connect to any other page...

Hi Anon, providing you have all the correct modem/router settings from your ISP, I would think you need to sort your MTU settings as below:

I prefer to find the MTU this way,
Finding the largest MTU by EXPERIMENT version 2

First reset windows with Dr TCP to MTU 1500.
Then reset modem/router to MTU 1500 save it, reboot PC and modem/router.

Next from windows, go to Start/Run and type in, cmd (click OK)
At the MSDOS-PROMPT type,

ping -f -l 1472 www.bbc.co.uk

Then reduce 1472 by 10 until you no longer get the "packet needs to be fragmented" error message or

Thank E7er

err....I'm not too much of a techie...you said to first reset windows with Dr TCP to MTU 1500

I'm don't actually know what Dr TCP or MTU 1500 is or how I locate/use it...?

- becc

I don't mean this unkindly, but if you need to ask you won't understand the answer. Do you know anyone who might be able to help?

unfortunately no, but I'd certainly give it a try...

Someone was telling me that although my pc appeared to connect to the homepage it may have been that the homepage was just cached and so I may not have connected at all, as it was not possible to link to other pages...

- becc

That is possible. Hitting the refresh/reload button in your browser would tell you immediately.

Firstly, if you haven't already tried it, follow my original suggestion. Plug your extension lead straight into the socket downstairs, no filter, no adapter, nothing. Check your phone works ok upstairs, if so plug the modem into the adsl socket of your extension and see what happens.

If you get nowhere, there seem to me to be three possible problems

1) There is something wrong with, or complete lack of, adsl on your line

2) There is something wrong with your extension lead/filter

3) There is something wrong with your modem/software

I'd say 2) is the least likely, if your phone's working. 1) you could probably get your ISP to check for you. Also there is at least one site which can tell you whether there's an adsl marker on your line or not, but I can't put my finger on it. 3) probably needs someone with a bit of knowledge. Someone on the forums here might be able to do it for you, otherwise you may just have to get a man in.

Sorry I can't be of more help.

You need to hold down Ctrl while you refresh or you'll be reading from the cache again.

I've figured out some of what E7er meant about Dr TCP.

I've downloaded the top ZIP file here...
http://www.dslreports.com/drtcp

This has brought up a little box entitled "Dr. TCP (Windows 2000/XP). In the bottom right corner of the box I have entered the numbers 1500. I think this means I have now changed the MTU to 1500 as I have saved this change.

How do I now reset the modem to MTU 1500?

The modem is shown here at the bottom of the page...

If you can't get a connection then messing around with the MTU, which may (but probably won't) give you a slightly higher speed once you have a connection, is a waste of time.

a marker only comes into play when an order for broadband is trying to be placed, not after the broadband has been provisioned!!

I was wondering who'd be the first to spot that.

I'm not sure what you mean...what do you mean by "a marker"?

I would think, your best bet is to get help from Talk Talk support, send them an email and ask them for the correct settings for your router and see what response you get.
