I tried to set up my 2TB. It suggested that I do my initial back up attached with a Ethernet Cable. I did that and over night it backed up my Macbook. I then tried to do a follow up back up (while still attached) when I woke up and it did that very quickly, as expected. I then unattached the cable and tried to do it over wifi and my macbook could not find the time capsule. Now I do not have the TC attached to my router, should it be? I would prefer to have the TC in the office and the router is is the living room. What am I missing? Also, I have a 500g hard drive on my Macbook but the TC said that I have only 1.77TB left for space on the TC, what is taking up the other 233g?
