evo vam dio mog maila koji sam poslala njihovom help-desku
ako neko ima slican problem ili zna nesto o ovome, zamolila bih vas da mi pomognete
"Skoro svaki put kada zelim da se konektujem javi mi neki problem (ili moram disable/enable mreznu karticu - modem je preko mrezne i ima zasebno strujno napajenje) ili nesto slicno. Nakon sto su vasi ljudi kreirali konekciju, utvrdjeno je da se desava neki konflikt s mreznom karticom, nakon cega sam ja kreirala jos jednu dodatnu ali sam instalirala RASPPPoE (winXP navodno vec ima ovo) i tek nakon toga sam bez problema pristupila internetu. Danas uopste nisam bila u mogucnosti ostvariti konekciju jer mi javlja neku gresku koju ja ocito ne znam otkloniti. Mislim da se takvo nesto ne bi smjelo desavati."
juce je radilo bez problema...danas ne radi
a win XP objasnjava gresku kao:
Error 678
