>HI,
>
>I have an ADSL line with BT. Were about 3 miles from the exchange, in a
>fairly remote house out in the country.
>
>Ive recently gone from a 512Kbps service to an up to 8Mb and after the
>initial test fortnight got a princely speed increase to... 576kbps.
>
>Ive changed the old Belkin modem for a Netgear DG834 which is supposed
>to be good with noisy lines, and incidentally allows me to monitor the
>line noise stats.
>
>After watching it for a week or so, its obvious that the noise margin is
>cyclic and much worse during the hours of darkness: I get around 14dB
>margin +/- 2dB between 7:00 and about 15:30 then it drops off to 4dB
>+/-6dB(!) for the rest of the time.
>
>I know about extra noise during daylight hours due to the sun heating
>things up, but I hadnt come across this one.
>
>Any ideas on the cause, and even better a solution?
