I have just had a BT broadband line installed and I set up a network so that it linked to my Mac, it's visible in the Airport window. I then installed a new Time Capsule and it asked me to set up a network and name it. Under the Airport icon in the top bar I can see both networks along with other nearby wifi networks in the high street.

Is this normal as the other local businesses only seem to have one visible network in the public domain?

    Yes, it's normal, especially if you keep the cursor hovering around the AirPort icon in the top bar (but even if you do not).


    When you hover around the AirPort icon, you should see "Looking for Networks .." appear.

    thanks, my query really is whether or not I can just have one network showing because at the moment both are visible to anyone within maybe a 100m radius? I would prefer to have just one publicly visible.

    If Apple's AirPort Utility recognizes your router, then here's how to do what you want:


    Open AirPort Utility (in your Applications > Utilities folder).  Click the "Wireless" tab on top, then the "Wireless Options" button.


    Finally, when the one you want to hide is displayed, check the "Create hidden network" box.

    Thanks, I'll give it a try when I get to my office later

    Hi, I'm at my office now, I've opened Airport Utility and it shows the attached pop out windows, the second one is the result of clicking on the red button. It doesn't offer the option that you mentioned though as far as I can see, I dont see a wireless tab. Screen Shot 2013-08-09 at 08.24.25.pngScreen Shot 2013-08-09 at 08.24.11.png

    Click the "Edit" button:

    ...and then on "Wireless Options...".

    Thanks I have done that now, both networks show in my wifi drop down but presumably anyone else won't now be able to see the hidden one?

    I assume that your  BT broadband modem is "Also" a WiFi router


    AND that your Time Capsule is attached to the BT router via an ethernet cable, where the ethernet cable attaches to the Time Capsule's WAN port.  Since your Time Capsule has a 192.168.x.x address, I think this is correct.


    If my assumptions are correct, then you should configure the Time Capsule for "Bridge" mode.  That is to say you do NOT want to create a "New" network, you want to bridge the existing network through the Time Capsule.


    Next, you want to give the Time Capsule the same network name (that is to stay the same WiFi SSID name) as the BT network, AND this is very important, the exact same WiFi Password.


    This will create a "Roaming" network, which is what companies use to give WiFi coverage over a very large area via multiple WIFi access points.


    Next assign your Time Capsule to different WiFi channels than what the BT WiFi router is using.  For the 2.4GHz 802.11g radio you want to be at least 5 channels away from what the BT WiFi 2.4GHz 802.11g radio is using to avoid any interferences.  In the U.S. we are restricted to 2.4GHz channels 1-11 (not sure if the UK is just 1-11 or if they allow 1-13).  And when assigning 2.4GHz channels, look at the channels your neighbors are using and try to stay 5 channels away from the neighbors that have strong signals (which would be the one that live closes to you).  You can get utilities to see the other WiFi routers in your neighborhood and their assigned channels, such as iStumbler from someplace like <http://MacUpdate.com>


    You could also try (from a Terminal session)

    /System/Library/PrivateFrameworks/Apple80211.framework/Versions/Current/Resources/airport -s


    If you do not need a roaming network, then still put your Time Capsule into "Bridge" mode, but now see if you can turn off the WiFi radios  of either the BT WiFi and use your Time Capsule for WiFi, or see if there is an option to turn off the Time Capsule radios and use only the BT WiFi.

    ok I'll look into this and report back, thanks Bob
