The next device would be the Linksys. Via ethernet.
I cannot provide hands on advice with Linksys, but can tell you from working with their products in the past that you will need to get in touch with Linksys support to ask them how to configure (and if it is possible) to set up the Linksys device as a Wireless Access Point, or WAP, as it is known.
Connect an Ethernet cable from one of the three LAN <--> ports on the Time Capsule to the WAN port on the Linksys.
The Linksys would be set up to provide a wireless network with the same wireless network name, same wireless security and same password as the Time Capsule network.
I was looking to see what my screens should say as they do not look like the screens shown in the instructional page.
Sorry, not sure what document that you are referring to here.
If you are looking at an Apple support document that is linked at the top of this thread, it will indicate how to connect the TC to other Apple routers......but not a 3rd party product like Linksys. Since the TC is already set up, and you are not connecting another Apple router.....an Apple document.....if that is what you are looking at......will really not be relevant to the Linkys router.
If you are looking at a Linksys support document, I would not be familiar with that, but will take a look if you have a link to the article.
