Create Guest Network on Time Capsule

Welcome to the discussions, wharfinger!

Please open AirPort Utility and click Manual Setup

You'll see a row of tabs below the row of icons. If your Time Capsule can be configured to use the Guest Network, you'll see a Guest Network tab.

If you don't see this tab, you may have an earlier generation Time Capsule that did not include this capability, or your current network configuration on the Time Capsule will not permit this setting to be enabled.

You can check your Time Capsule as follows:

Close AirPort Utility if it is still open
Now open AirPort Utility again and
Your Time Capsule will appear on the left
On the right side of the window....you'll see a message.

That message must read AirPort Utility has found a Time Capsule (Simultaneous Dual Band). If you don't see this, you have an earlier generation Time Capsule that does not provide the Guest Network option.

This information indicates that your Time Capsule is in Bridge Mode because AirPort Utility detected that you may have another router or gateway ahead of the Time Capsule on your network.

This would be a device that is a combination modem and router, usually with 3-4 ethernet ports on the back although some devices have only one port.

I would recommend that you leave the Time Capsule set where it is if everything else seems to be working correctly on your network. Unfortunately, the Guest Network is not available when the Time Capsule is configured in Bridge Mode.

If you want to try another setting *+that may or may not work.+*..

Open AirPort Utility and click Manual Setup

Click the Internet icon

Change the setting for Connection Sharing to "Share a public IP address"

Update to save changes. AirPort Utility may or may not let you do this. If it does, you'll need to click "ignore" when you see the error messages about a Double NAT on your network.

Double NAT means that you will have two devices both trying to act as routers on your network, which can cause conflicts and improper network operation. I'm not recommending that you do this, but some users can get away with it.

No guarantees here. Up to you.
