I'm looking for a new modem but I don't know which one is better between the three I have picked out. One is a motorola SB5120 it has 38Mbps download stream and 30 Mbps upload stream. The other is the linksys BEFCMU10 it has 30Mbps 64QAM and 43 Mbps 256QAM. The last is the d-link DCM-202 and that has 42.88 downstream and 10.24 upstream. I'm not that great in the networking area so if somebody could help me thatd be nice.
