Using apple time capsule as wireless backup on existing network
I just acquired an Apple Time Capsule, 3rd generation (A1355). I have a mac and a PC in my household. My goal in getting this device was to be able to backup both computers on the existing wireless network, but as I've explored setting this up, it seems like it may not be possible.
I'd like to have the Time capsule join my existing wireless network to serve as a remote hard drive for automatic backups. But, as I was setting up the device, it seems that I can only "wirelessly extend" an airport network. My network is run off of a D-Link wifi router. The goal here is to have the time capsule in a location that is removed from both my computers and the wi fi router. Right now my computers and the wifi router are all in the same place. If I added the time capsule to that location through a wired connection, it defeats the purpose of having the backup. My main reason for having a backup is in case someone breaks into the house and steals the computers (which has happened once before). Therefore, it's important that the time capsule is in a different location in a different room of the house, ideally located in a cabinet or drawer that would not be a target for a thief.
From all that I've read, it seems like the only way to add the time capsule to a 3rd party router is to do this through an ethernet cable. Has anyone figured out how to do this wirelessly? For a backup device, seems like keeping it connected to the router through a wired connection sort of defeats the whole purpose of a backup because the backup is right near the equipment that it's backing up.
Of course, I could replace the d-link router with the time capsule serving as the wifi router, but I'd have the same problem - that location is right by the computer and would be a prime target for a thief.
Any suggestions? I purchased this time capsule because it received good reviews, but am surprised that what would seem to be a pretty basic backup requirement is missing on this machine. Any help would be much appreciated.
Thanks,
Brian
