    I fixed my WAG354G with my new ADSL connection it was working okay for few days, but time to time I found my ADSL connection drops. From yesterday onwards, my browsing is very very slow and some times very difficult to connect.

    I don't have any ADSL filter, is it very important to have a filter?

    Sure !
    It separates low frequency used by old phone sets (under 20 kHz) and high frequency used by DSL communication...

    Is it filter or Microfilter. How to fix it between teh phone and line or model and line?

    I have 2 phones in the house parellary connected.

    You have to put a filter on each phone plug used (by phone, fax or modem)...

    See here and there !

    Thanks for the reply and informtion.

    So I have to put microfilter to every phone, fax and PC modem and not to the line between the wall and ADSL modem?

    ADSL modem is a modem, obviously a filter is required !

    You "can" put a filter on your other devices...if they seem to need it. I do not install them unless needed. Regular phone handsets often don't need the DSL filters, I only put them on in the cases where you hear the high pitch sound. Cordless phones can interfere with the DSL, so they often require one..else you'll notice the DSL may drop when someone uses the cordless phone. Fax machines usually don't get along well with the high signal of DSL....and they'll act up unless you put a filter on them. Any old dial up modems used for payroll or bank deposits...will often require one.

    I try not to use filters..unless needed.

    But your DSL unit..the bridge...no, you don't filter those. You wan't to run those bare naked.

    I have two normal telephone sets, and one computer connected parallely. So I assume that I put only a filter to the computer modem?

    sorry guyz but ADSL filters are simple low-pass filters, and you dont have better performance if you use it. The plug named "ADSL" of a filter simply take the signal coming from the wireline without modifing it. Inside all modem there is a high-pass filter that filters the signal in the right way.
    If you experience problems with your ADSL connection first of all take a look at the Status - DSL page of your router and check if the signal margin and attenuation are ok. Then try to unplug all the phones in your home and test your router to see any changes. For help feel free to ask!

    Sorry Guy !
    The problem is not to have a better performance with, but to don't have a poor performance without ! :p

    that's exactly the same thing!
    Performances DO NOT degrade without an adsl filter, as it filters only the phone signal. Open your filter and check what's inside if you dont believe me!!!

    My conexion drops to very low speed without a microfilter on mu phone as it takes lots of ADSL signal withoout it.

    Therefore you have to splitt signals, or filter them with microfilters on your phones.

    Yes, and me I'm the Queen of the UK ! :grin:

    I dont think it should be possible, as surely the old queen of UK has more knowledge of adsl than you...

    They are there to stop the other devices i.e. phone, fax machine, etc. interfering with the signal for the ADSL. They do make a difference which is why ISP's and router manufacturers supply them and every guide tells you to install them. I've gone to sites where people have had flakey internet connections and it was purely down to the lack of microfilters.
