    Smile ADSL filters.....

    My new sky broadbean is about to go live....soonish.

    Since I am new to the whole ADSL thing I don't know much about filters.

    Basically I am in a new build house that has a BT master socket + 4 extensions throughout the house. There are 2 phones using a socket each throughout the house.

    My question is: Do I need to purchase a filter for all the extensions in the house, or just for the ones that are in use?

    If I do indeed need to get 5 (well 3 assuming the sky router comes with 2) filters, where should I get them from ? - do the £2 ones from ebuyer do the same job as the £8.99 ADSLNation ones?

    Thanks!

    Just the ones in use.

    You get what u pay for with filters so if ur a long way from the exchange the adslnations ones will be better

    Re: ADSL filters.....

    The more expensive filters are impedance matched on both outputs, so give better performance. Every phone. answerphone, fax or anything connected to the phone line needs a filter. In theory you don't need to filter the router, but in practice, using a proper matched filter will improve performance.

    Alternatively you can replace the front of the master socket with a filtered one, so all the extensions running from that master socket will be filtered at source. The downside is that the router can onlty be plugged into the ADSL socket at the master socket, which may be restricting.

    Re: ADSL filters.....

    The better the filter the better the noise level on the ADSL line, Ive had dodgy filters which would cause the line to drop and replacing them fixed it.

    Re: ADSL filters.....

    The £2 ones from Ebuyer are bad - just removed one the other day strangely enough. A very good friend is having serious issues with his line currently (3 engineers in a week ), and getting one of the BT filter faceplates put on raised his SNR from 8 to 12 at the same speed.

    Probably not as much difference if you're close to the exchange, but for something thats going to be brought once and left in the wall for years, its hardly a costly investment.

    Re: ADSL filters.....

    Didn't realize there was a difference in these filters. My neighbour has the cheapo's. I wonder if that's why he only gets 2.5mb when it says up to 8mb.

    It might be a contributory factor, but thereare lots of reasons why sppeds may vary - overall linre condition and distance from the exchange are two main factors. However a better filter won't do any harm, and might improve things a little.

    I'd recommend getting some good filtered faceplates, much easier.
