you haven't mentioned Promethium ore (1 piece), which is also required for this quest. I believe you have it? if not you'll also need Mining laser MKII and unlocked Outer belt since you can't buy this ore. Though I think there is a chance that a 'ship in distress' event could have it.
then you can visit T'Ris at the bridge any time (I think) before 18:00 (end of her shift), and then she tells you to meet everyone at 19:00 in Maintenance cell on 2nd floor.
and the Uplink has to be just above 75%, no need to set it on 100% - full three lines with one AI Core will be enough.
