Údaje z ADSL modemu - jak kvalitní je moje linka?

Tomas J. (27.5.2012 14:40:00)

Zdravím, chtěl bych se zeptat někoho zkušeného, jestli pozná z výpisu z modemu, jak kvalitní je moje linka ADSL. Downstream Upstream SNR Margin (dB): 16.3 31.0 Attenuation (dB): 17.0 12.5 Output Power (dBm): 12.7 13.2 Attainable Rate (Kbps): 8704 1348 Rate (Kbps): 6144 384 Mám problémy s ADSL od O2 - pomalé, upload blokuje download, padá...snažím se kontaktovat O2, ale také bych si o tom něco rád zjistil sám. Má cenu investovat do lepšího modemu? Třeba Cisco apod. Teď mám ASUS AM200G. Díky za pomoc!

Attenuation pak cca 40 a níže.
