Does anyone know if I need one of these for the actual broadband modem/router? I know I need one for the phone (which is downstairs) and was wondering if I need another one for the modem as well or can I just plug it straight into the socket as I have a cable with a BT plug on it?

cheers

NO You definitely do not need one, you can just connect the broadband modem / router using a standard modem cable direct to the phone socket. Put one on the actual broadband router / modem and it most likely won't work.

I believe the filter is exactly that - it filters out the frequencies used by ADSL from whatever its connected to, try plugging a phone in without a filter and you can hear a high pitched noise while the ADSL is connected. Some filters have 2 connections, an unfiltered one marked for data and a filtered one marked for the phone, but the data connection of those sorts of filter doesn't actually do anything.

You will need a microfilter (looks like a socket doubler) for every phone socket in your house. Otherwise, if you try using the phone when the PC is on, you'll get static varying from irritating to impossible. IIRC DABS do them for £4.00 each - or just do a search for 'ADSL microfilter'.

Check out the ones from Dabs.com

Don't go for the cheaper generic branded ones, they whistle. The Fujitsu ones for about £7 work a treat.

whack a filter on every phone you have, but don't put a filter on your BB connection.

I've had MANY line drops in the past due to phone calls...

Beleive me, they're annoying!

btw, it's late and I've been drinking, if this doesn't make sense, let me know!

SolWise do some great DSL kit... including very cheap (but quality) mutil-packs of filters...

I would recommend you do use a filter. Although it was mentioned above that the ADSL port on a filter does nothing, I am afraid this is not true.

The ADSL port itself (at least on the good filters) is itself filtered to prevent the telephone equipment interfering with the modem. It prevents harmonics and other electrical interference on the telephone network getting through to the modem.

It is worth spending a little extra on the filters. Some of the cheaper ones do not conform to the BT spec and can cause all sorts of problems.

For more in depth information, look here: www.adslnation.co.uk/support/filters.php

Cheers for all the replies everyone

I've decided to get another one just to be on the safe side. For the sake of a few extra quid I went for the Fujitsu one, after all there's no point in have a cheap one if it doesn't work

KITT - I've got 2 spare in my loft. If you want one, mail me your address. They came with my wireless router which the company paid for, so you're welcome to have one!

Correct but you do need a filter for every socket in the house for a good data circuit - according to the nice BT man who came to the house. Bought the D-link ones from DABS

Of course...it depends how your phone sockets are wired. My upstairs extension is a simple DIY job that just plugs into a socket doubler downstairs. So I use the microfilter downstairs and effectively filter the entire upstairs extension for A/DSL.

Still, for the sake of 3-7 quid who cares?

In fact, why am I even writing this ?

Thanks for the offer Miniman but alas I've already ordered one! I'm sure someone else will take you up on that offer though
