How do I set up a guest wireless network on a Time Capsule, running Mountain Lion.  I see no option for setting up a guest network.


iMac, OS X Mountain Lion (10.8.2)

    By the way, the Time Capsule is not in Bridge mode, and the modem from the ISP is a simple modem.  I previously had a Belkin router which easily had a guest network setup.  All I've done is pull the ethernet and modem cables from the Belkin (and unplugged the Belkin), and plugged all the ethernets and modem into the time capsule.  I have the main network working fine.

    Launch AirPort Utility and select Help > AirPort Utility Help from the menu bar. Enter "guest network" (without the quotes) in the search field. Read the page titled "Set up a guest network."

    I have done this (go to Airport Utility Help), and the option indicated (to enable guest network) does not exist for me.

    There are more details here:

     

    About the Guest network feature of AirPort Extreme (3rd Generation or later), Time Capsule (2nd Generation or later), and AirPort Express 802.11n (2nd Generation)

     

    If you've followed the instructions, and your AirPort firmware is up to date, then you must have an older Time Capsule that doesn't support the feature.

    This is a brand-new time capsule, ordered last week!

     

    I had no problem setting up a guest network on my Belkin router.  All I've done is swap out the Belkin for the Time Capsule.

    The device is under warranty. I suggest you call AppleCare. If they give you a better answer, please update this thread so others can benefit from your experience.

    Is it possible that you are somehow not locating the setting, despite telling us that it is not there?  Click the Wireless tab in AirPort Utility and the window will look like this if your modem is compatible with the Time Capsule.

    The window looks exactly like this, except the "Enable Guest Network" section is missing.

    Possibilities:

     

    1)  The Time Capsule is not compatible with your particular modem for this feature

     

    2)  The Time Capsule is defective

     

    3)  Although "new", you somehow received an older version of the Time Capsule.

     

    That is why we have been asking for the model number on the bottom of the device

    We can close all three threads.  Here is the summary of my experience with Apple Support:

     

    Apple requested that I obtain the serial number of the Time Capsule (I was not at my computer at the time), and scheduled a call-back at 7PM.  While doing that through Airport Utility, I browsed the Airport help page.  In this way, I found that the Time Capsule was in bridge mode (which had been suggested in the forums, but I didn't realize bridge mode is the default for Time Capsule).  When I set it to DHCP mode, the guest network became available.  But I got a warning that made it sound like it was a bad idea if my ISP was providing dynamic addressing (which it is).  If I set it to DHCP/NAT mode, I did not get the warning, the guest network became available, but the Time Capsule had an error indicating double NATs (and the Time Capsule status started blinking amber).  At seven PM, I promptly got a call from Apple.  I just read him the iMac serial number, and the rep understood and confirmed it as valid.  I explained the problem I was having with the guest network, and the double NAT error message.  The rep quickly explained that the Time Capsule is unable to determine if the upstream modem is a simple modem or a modem/router.  So the double NAT is not an error message, but only a warning that there could be two NATs if I have a modem/router and not a simple modem.  He told me I could just click on the double NAT indicator and have Airport ignore the message.  Which I did, and the message went away and the Time Capsule status indicator went to solid green.  Time elapsed with Apple, not more then ten minutes!  As opposed with my experience with Microsoft: after migration, MS Office requested my product key.  Even though I had a valid key, it was unrecognized.  Took me about a hour and half to get through MS support and get a valid key!

    You don't need or want double NAT. Configure the modem in bridge mode so that it passes through your public IP address to the TC. I can't tell you how to do that.
