Poštovanje i pozdrav!
Evo borim se kod kuće s brzinom dsl-a i pizdim. Imam hr.duo i trenutno mi se vrti brzina na 512/192 i to kad mi ograniče brzinu na 512. sad sam tražio da mi dignu na 1mbit i sad je stanje 448/192. ok, kužim, imam lošu liniju, ali stvar koja me zaintrigirala je da susjed preko puta ima čak i malo lošiju liniju, ali njemu se spaja na 1mbit bez problema.
evo podataka

Jedino stvar koja se bitno razlikuje je SN margina. Malo sam istražival po netu i piše da
niža SN Margina daje bolje brzina, ali i nestabilniju vezu, tj. viša margina daje stabilniju vezu.
E sad jel zna netko o čemu ovisi margina? Kak ju sniziti? Kome treba popušiti i platiti za 1mbit?
e da, vidim da se modulacije također razlikuju. jel to do modema ili isp-a?
