Dual band N supposed to use two frequencies, A (5 GHz) and B/G (2.4 GHz). The 5 GHz channels do not overlap like the 2.4 GHz channels do. Getting full speed on N in the 2.4 GHz band requires 4 channels and multiple antennas. Having G devices will slow it down but the N devices should work faster than the G.
