Dual-Band Wireless Router Question in Hardware Posted June 20, 2011 · Report reply I just purchased and installed a Netgear WNDR3700 Dual-Band wireless router (2.4GHz and 5GHz). This is the first dual band router I've owned, and I'm not really sure how they're supposed to operate. What's puzzling me is that I never see any "activity" on the 2.4GHz band ? it all seems to be on the 5GHz band. Is this how it's supposed to work ? or are both bands supposed to be working simultaneously? Maybe I need to adjust some settings, but not sure what to change.
