Hi guys, this may seem like a really strange situation and question but my I am helping a friend set up a Airport Express to join his either Time Capsule or Virgin Media Superhub 2 (depending what hes decided to be using when I get there) to extend the wireless signal of his already established network. Currently he has Time Capsule 3rd revision and a new Superhub 2 (beta tester) so they run 2.4 and 5Ghz simultaneously. Now the strange part comes is that he wants the range of the network extended but only for one wireless device to be able to connect to it. Is this possible? I was thinking that if only the 5Ghz signal could be extended and not the 2.4 that would help as the device he wants to access the extension is an iPhone 5 possibly his iPad 4. Now the normal network he still wants all wireless devices currently able to connect to still do so. Can this physically be done? He has bought an Apple Airport Express which is on it way. Thanks and I am sorry for the crazy scenario.
