Connecting TC To Existing Wireless Network

Here is where you need to go in Airport Util. You want to extend the network.

Here is the deal though, for this to work the landlord's wifi router will need to support WDS, and it might not. Then even if it does, often using WDS between different brands just does not work well.

 

Yes, you can do that. Just set it up as a normal wireless network (not extended). The amber light will flash because there is not Internet access, but you will still be able to login to the TC wirelessly and backup. I believe you can click on the amber light in Airport Util and tell it to ignore the error and stop the light flashing.

But you will have to jump back and forth between the landlord's wifi for Internet and your TC wifi for backup. It will work though.

 

Excellent!

Do you have any data on the TC that you can't lose? I would start Airport Util erase the TC disk, then start a fresh backup.

 

Make sure Time Machine is off on your computer, then try a reboot of the TC and try to erase the disk again from Airport Util.

Also do a restart of your computer.
