2.4 Ghz sucks for wireless period. I have 68 networks in my area which is a overlapping mess. I just got a new iPod Touch and even just streaming music on 2.4 Ghz it would drop out or even disconnect Now with WiFi on 5 Ghz is so much better.
Anything that has a Ethernet port is hardwired and the only thing on 2.4 Ghz is my printer.
