um ganun talaga yun KAHIT SAANG BANSA, UP TO means the max theoretical speed you can hit is capped at 3mbps, and there is no guarantee, nasa contract/terms and conditions yun , a lot of factors can affect your speed such as Data Traffic, number of users connected to the port youre connected, maintenance/upgrades they may be doing without telling subscribers
di mo rin pwede sabihin na under 1mbps ka or unsable kasi they can PING your modem and see what your actual speed is
dasal na lang ang pagasa mo so always have the optimal speed
