I must say that I am quite computer savvy but I don't really know much about networking. I picked up a new dual-band after my modem exploded and fried the ethernet port on my old router (AND THE ONE ON MY i5 iMAC! ) and don't know much about it. I've read that 5GHz is better for streaming music and such and so I have my iMac and Apple TV connected to the 5GHz band. Are those facts true or no? Also, I've found that since it's technically a seperate SSID that my iPhone won't be able to interact with the Apple TV. Can you explain the differences to me and advise me if I should just connect everything to the 2.4 band. Thanks. -Dale PS. For what it's worth, this is the router I picked up (only $70 at Walmart).
