I'm trying to get my 2009-era Time Capsule to extend my home wireless network (broadcast by a non-Apple router). I reset the Time Capsule and AirPort Utility can see it on both my iPad mini (iOS 6.1.3) and my Mac Mini (OSX 10.8.2). In both cases, AirPort Utility will happily allow me to set up the Time Capsule and have it join my existing network. When I go back and tell AirPort Utility to have it extend my wireless network, the Time Capsule tries to update itself and then just fails. It tells me "An error occurred during the update", and then AirPort Express can no longer see the Time Capsule:

annoying as heck!

At this point, I restore the Time Capsule using the tiny button on the back and lather, rinse, repeat.

The Time Capsule hadn't been used in a few months, so I tried this both before and after updating the firmware. There has been no change in the result.

Where do I even begin to troubleshoot?

Ok, I think I understand what you're trying to do, because I've done the same. The answers listed aren't 100% accurate. If what you're saying you're wanting to do is say receive the "internet connection signal" (i.e. dsl, cable, fiber optic) from it's respective carrier & then direct it through the Time Capsule in hopes to solely extend their signal then the answers above are essentially accurate. I say essentially because based on some carriers newer router-modem combos, you CAN set up the Time Capsule in bridge mode and allow it to work as a repeater (or extend your network.) Often, with the older Time Capsules and many carriers it just becomes a pain & simply doesn't play nice all the time if you do get it to work.

It seemed to me though that wasn't exactly what you were asking to do. It seemed/sounded like you just wanted to take the signal, bounce it to the TC then to the Express. If that's the case it can be done, without any extra purchases. Certainly without any addition of a wireless jack extension, which no offense to the individual recommending it, but would be a really silly option in this scenario.

  1. Place the Time Capsule next to the carrier's (i.e. I have my Uverse fiber optic modem next to my 2011 Time Capsule.)
  2. Then connect the 2 via an ethernet port. At that time what you'll want to go through your carrier's step to disable the carrier's wireless signal.
  3. Then allow your Time Capsule to serve as your Wireless router. You may want to go through the Air-Port Utility Set up.
  4. Then connect your Airport Express & it will allow me you to then "extend" the network from the Time Capsule.

The great thing is the Airport Express offers you incredible flexibility due its portability. I know with mine I get a pretty good signal without it but with it, I can put it out on the back patio and enjoy streaming music. I have a friend who enjoys doing a movie night once a month in the summer & uses the same set-up to stream movies from their Apple TV to their projector in the driveway on to the garage. It's really cool. All the kids in the neighborhood and families get together for an old fashion block-party of sorts in drive-in movie style. All thanks to a well set up network. I hope that helps answer your question.

If you are trying to extend a wireless network that is not an Apple Airport base station it cannot be done. You can join a network but this will not increase the range of your wireless network.

Unless you have a firmware that supports WDS on your 3rd party wireless router.

    Thanks for this answer. It was very hard to find anyone giving advice on this. – djangofan May 10 '15 at 16:41

The Time Capsule can only "extend" a wireless signal....using wireless only....from another AirPort Extreme, Time Capsule, or AirPort Express.

Apple is doing this in a proprietary way and non Apple hardware is not supported.

In any case WiFi extension is generally flaky and to be avoided. I strongly recommend you look into using Powerline plugs like these to reliably get network connections into distant rooms:

  • Powerline plugs are an interesting solution, but the devices I need connected in my back room aren't ethernet-ready, unfortunately. – hairboat Aug 13 '13 at 13:49
