use time capsule only for backups

How do I or can I use Time Capsule only as a backup disk on it's own network

You probably don't really want to use the Time Capsule on its own network. It won't be able to function on the Netgear network if you do.

That being said, it is possible to set up the Time Capsule on its own network if you want, but then you will have to manually switch from the Netgear network to the Time Capsule network whenever you want to back up your Mac(s) and then manually switch back over to the Netgear network for normal network and Internet service.

Best option would be to connect the Time Capsule using an Ethernet cable to the Netgear router, set up the Time Capsule in Bridge Mode and then turn off the WiFi on the Time Capsule. That way, the Time Capsule will be on the same network as the Netgear router and you will be able to back up your Macs to the Time Capsule over the Netgear WiFi network.

Another way to say the same thing.......the Time Capsule will function as a back up hard drive only for the Netgear network. Things will be tons easier this way.

Post back if you need more tips on how to set things up.

Turning off the WiFi is the last step that you would perform. You have to get things working.....before....you turn off the Time Capsule WiFi.

Take a look at this other current thread for step by step instructions. The other user is doing the same thing that you want to do......and his Time Capsule is now set up and working correctly using the information that I provided.

Now, we're working on getting the backups going again.

Can I set up my Time Capsule to be just a back up disk?

Did you perform a Hard Reset on the Time Capsule to erase the old network settings and then set it up again so that it would pick up the new settings that it needs from your new router?

Once the Time Capsule is set up again, you then need to turn off the WiFi on the Time Capsule using AirPort Utility.

Update......Everything is working correctly for the other user who wanted to do the same thing that you asked about.
