Filters are the sort of thing you just fit and forget.

To some extent yes, but they aren't all created equal. Many moons ago
I did the research on what was (then) the "best" face plate ADSL
filter. Bought the one that had the most consistent good reviews,
fitted it. Yep during the day if allowed good speeds maybe 500Â* to
1000 kbps faster than the fliter I was using. But at night it
couldn't sustain that rate and the modem would retrain to below the
rate the other filter could sustain day or night. The modem wouldn't
retrain back up at dawn either so you were "stuck" at the lower rate.

might that not be caused by the overloading of the local network?

Nope. training speed is a measure of signal to noise. AM radio after
dark is the killer.

Filters should do NOTHING to the line-router - they only affect line-
telephone.

Well that's rubbish.

The filter is there to stop the phone altering the line characteristics
and causing the modem to have to retrain when someone makes a call.

They aren't there to stop the DSL "interfering" with the phone as the
phone should be rejecting the frequencies DSL uses.


If you have no phone you need no filter at all.



Got that bit right as long as you don't have a FAX or an answering
machine, etc.
