I haven't found a clear solution to this. I have a wireless netgear router in my living room. My iMac in my bedroom is connected to the wifi network fine. I got a time capsule 1TB. All I really want is to use it to backup my computer to it wirelessly. I would like for it to join the existing wireless network if possible though. I can not replace my netgear router with the TC or even connect the two via Ethernet. The time capsule is staying in my room! I tried using airport utility to join the TC wirelessly to the wifi network. I chose the network and entered the wep. After it restarted the TC after configuration, the airport utility couldn't find the TC and the light flashes amber. What do I do? If the network thing is out of the question, How do I just wirelessly back up my comp????
