Help, I think I changed the settings in itunes and caused it to...

Question

delete all my songs. I think I have it set up to not sync automatically. I do not want it to sync up all the time because I have been working on correcting names of songs and albums on the itunes and was charging and syncing slows down my pc. Anyway, I downloaded all of my music (last night) so I could listen to ipod while at work today and this morning I had finished correcting titles and genres and such plus added a cd and connected the ipod so that it would update everything. I'm pretty sure that I checked and everything was ok, and then disconnected (said was ok to disconnect), then I plugged ipod back in...to charge only. As I was leaving for work (battery was not fully charged) and I ejected the ipod. Got outside and all music was gone.
Any ideas what settings might have done that or what did I do wrong?
Now currently re-downloading all my songs...getting comfy for next few hours.
Second question is, say I add only one album to itunes and update the pod, will this take a long time everytime or go quicker as it is not so many song...meaning does it go through all the songs again or just the changed ones?

Answer 1

Double NAT appears when there are two devices both acting as routers on a network, so your modem/router is acting as one router on the network and the Time Capsule is also doing the same thing. This may....or may not....lead to some unforeseen problems.
The solution is set up the Time Capsule correctly in Bridge Mode....as your previous AirPort Extreme was set up.
The downside to doing this though, is that the Guest Network will not function correctly when the Time Capsule is setup in Bridge Mode.
The reason for this is that Apple assumes that you will be using a simple modem......not a modem/router.....with the Time Capsule.
If everything seems to be working OK despite the Double NAT message, then you might want to try simply ignoring that message, and by choosing to do in AirPort Utillity, the status light on the Time Capsule will turn to green.
Another potential solution would be to ask your Internet Service Provider to supply you with a simple modem......not a modem/router.
It is also possible that your modem/router might be able to be reconfigured to act as a simple modem....but that is a more complicated approach, which will likely require assistance from your Internet Service Provider.
