I apologize in advance if this is a silly question/ Our family owns an iMac, 2 Airs, iPod, 3 iPhones and 2 iPads. We have a Netgear dual band N wifi. The Airs and iPhones can only detect the 2.4 ghz band while the iMac and iPads can detect both 2.5 and 5 ghz. I want to replace our old printer with a wifi airprint enabled printer (looking at the Canon MX890). Here's the question: Do all our devices need to be connected to the exact same band as the printer in order to print wirelessly? In other words, if I set up the printer on the 5 ghz connection will our Airs and iPhones not see the printer since they can only detect 2.4 ghz? And likewise, if I set up the printer on the 2.4 ghz connection yet our ipads and iMac are always on the 5 ghz connection will i need to toggle them over to the 2.4 band every time we want to print? Again sorry if this too basic and a stupid question, I just want to understand this aspect before purchasing. Best Buy sales just had a blank look on their face and mumbled it didn't matter but I wasn't too confident they really knew.
