I would say it's safe to assume Reva can connect to most mundane computing equipment wirelessly using her rig; perhaps Lyssiah offers to try linking her computer to Reva's, and using its extra processing power to help clean up the signal enough to make out words which Valerie can maybe translate. I don't think just lending the computer to Reva will help (she's already using one), but passing DC 10 for Aid Another in this way should be automatic.
