Issues with AirPort wifi to iPhone/iPads. MacBook Pro OK.

I read carefully, but I cannot find anywhere in your posts where you first reset the Time Capsule back to factory default settings, and then set it up again. Did you do this?

This type of reset is critical whenever you are changing your Internet Service Provider (ISP), or you change the modem to which the Time Capsule connects. You have changed both your provider and the modem.

That being the case, we can likely help, but you will need to be willing to start all over again with a factory default reset on the Time Capsule and then move forward one step at a time. This will require a lot of patience. You will be changing network names and passwords, something that you might not want to do.

So, you may want to wait for other advice from other users.

If you decide to try our advice, we will first need the make and model number of the new cable modem that you have received before we can proceed.

I'll ask Tesserax to go over this with you since you reference his instructions.

It looks like Tesserax may not be online at this time, so we'll go ahead and get started.

First, power down the Motorola modem completely by pulling the power cord from the back of the device or from the wall AC jack, whichever is easier. Leave the modem powered off for at least 30 minutes. Disconnect the Ethernet cable from the modem as well.

Next, we will do the default reset on the Time Capsule. This is tricky.....you almost need to have 3 hands.

Power off the Time Capsule by pulling the power cord from the back of the decide and disconnect the Ethernet cable that is current connected to the Time Capsule

Leave the Time Capsule powered off for a full minute

Then, hold in the reset button on the Time Capsule firmly...and keep holding it in.....for an additional 10 seconds while you simultaneously plug the power back into the Time Capsule

Release the reset button after the hold period and allow a full minute for the Time Capsule to restart to a slow, blinking amber light status

Power off the Time Capsule again

After the modem has been powered off for at least 30 minutes....longer will not hurt...connect the Ethernet cable from the modem to the WAN "O" port on the back of the Time Capsule.

Power up the modem and let it run for 5-10 minutes....longer will not hurt.

Now power up the Time Capsule and let it run for 5-10 minutes....longer will not hurt.

Click the WiFi icon at the top of your Mac's screen

Look for a listing of New AirPort Base Station

Just below that, click on Time Capsule

The illustration below shows an AirPort Extreme. You will see Time Capsule on your screen

When you click on Time Capsule, that will start up the setup wizard to walk you through the installation to create a new network. The window will look similar to this, except that you will see a picture of the Time Capsule

Click Next

Use a short, simple name for your wireless network....something like pdvdp would be fine. Do NOT use the name that Apple suggests, which will be something silly like Patty's Red Apple Wireless Network.

Use a short simple name to call the Time Capsule......mine is TC, for example

Enter the password that will be used for both the wireless network and your TC device and Verify

Click Next

Follow the prompts. When you are done, the TC should be providing a wireless network with the new name that you assigned. Check on your Mac first to make sure that you can connect.

Then, try to get one iPhone to connect to the new network. If it works, then configure the next, etc.

However, do not proceed to the next device until you have the previous device working correctly. Keep setting up devices until all of your wireless device are working

Post back on your progress

Unfortunately, it appears that your Time Capsule is not resetting correctly. Leaving it off overnight will not help. You only need to power it off for a few minutes between reset tries.

Rather than a default reset, I would like you to try a Hard Reset. This is a bit different.

Power up the Time Capsule for a few minutes

Hold in the reset button on the back of the Time Capsule for 10 seconds, and then release

Allow a full minute for the Time Capsule to restart to a slow, blinking amber light status

See if that will allow you to set up the Time Capsule again

Also check with iPhone or iPad as follows:

On the home screen, tap Settings

Tap WiFi

Look for a setting of Set Up a New Base Station

Tap on Time Capsule to get the same setup sequence going

You do not want the setup utility "gathering information" for more than a minute or two. If it has not displayed the next window after a minute or two, it never will. More action is needed.

Are you using a Mac or an iPhone / iPad for the setup?

When you have a moment, check some settings on the laptop.

Open System Preferences (gear icon on the dock)

Open Network

Click on WiFi on the left to highlight it

Click Advanced at the lower right of the window

Click the TCP/IP tab

Make sure that the setting for Configure IPv6 is set to Link Local Only

Click OK, then click Apply in the next window

Then, go back and click Ethernet to highlight it and perform the same sequence as above

Restart the Mac

Then repeat the entire process for other Macs that you might have

You can delete the old network and any other networks that might appear there that you no longer need.

Nice work! You are welcome!
