One example... I have a Motorola SBG6580 that I use as both my cable modem and wireless router [0]. Although it claims to support dual band 802.11n, it really only supports one or the other, not both simultaneously. This means that if I have any wireless device in the house that doesn't support 802.11n, and specifically the 5 GHz band, then I'm forced to tell my router to fall back to 2.4 GHz unless I want to buy additional hardware.
