I am looking into either a new wireless router (draft-N) and a NAS system, or the Time Capsule as an alternative. Both are roughly similarly priced, so it depends on other criteria. What I was wondering now is if the TC offers the same degree of customisation as a regular router, e.g. DHCP with fixed addresses based on MAC address, port forwarding, etc. Is it possible to run 5GHz and 2.4GHz bands simultaneously to support older devices? If yes, is this only accessible from a configuration utility on the Mac or via a web interface from other computers (PCs for example) as well? Apparently (according to the manual on Apple's site) there is only a program for Windows & Mac, what about other OSes, are they left out in the rain? Thanks for helping! Helge.
