I have a new Apple AirPort Extreme (whatever the latest version is, with gigabit ports and dual band 2.4Ghz/5Ghz) and also have the newest version of the AirPort Express. I originally was using the Express for iTunes music streaming exclusively, however with my recent findings of how poor the 5Ghz range is, I would REALLY like to extend the network using the Express if possible. I DO have them hard-wired, so I am hoping that I won't have any wireless bandwidth sacrifice. I have a couple of questions about this type of setup outlined below and any help would be GREATLY appreciated. Is the express even capable of 5Ghz, and furthermore, is it capable of extending 5Ghz? Will all devices whether they are hard wired, on a/b/g/n (2.4Ghz) or n(5Ghz) be able to still stream music to the Express? Will there be any sacrifice of wireless bandwidth or anything else if I set them up in this manner (hard-wired)? Is it literally as simple as telling it to extend my unique 5Ghz wireless network name and it will just "work"? Is there anything else that I need to know or tips that any of you may have on doing this type of a setup? I have looked through TONS of documentation and searches about this and cannot find anything specific to what I would like to accomplish. All of Apple's documentation on this just talks about 802.11n but in the case of extending, I don't see anything anywhere about the 5Ghz band and none of the info I can find on the Express has anything about it one way or the other, just that it's 802.11n. Thank you again, I truly appreciate the help.
