I have a new Google Chromecast that I've been trying to install to cast Netflix from a laptop PC to our Samsung TV. After several conversations with Google (and also the Best Buy geek squad) it seems that the problem may be that the Chromecast has to connect to the internet via 2.4GHZ band only. Seems like 5.0GHZ is the default connection in AE.

 

The equipment configuration off all this is: cable company modem>Airport Express 802.1 (v 7.6.4)> NetGear network extender> laptop PC>Samsumg TV

 

Question: how can I get Airport Utility to set my guest network to use ONLY the 2.4GHz band (or should the Chromecast select it automatically)? The Google support guy said that the band selection is probably the reason that Chromecast will not connect to the internet even though it IS apparently connected to my home wifi network. If the band selection is automatic, I'm even more confused.

 

In Airport Utility I have set my guest network to allow other devices to connect with each other, but that doesn't seem to have solved the problem.

 

Any and all input or source references greatly appreciated.

    Unfortunately, you cannot select which Wi-Fi radio (2.4 or 5 GHz) the Guest network uses as it uses both simultaneously.

    but is it possible to isolate to 2.4 GHz on the main network if not the guest?

    It is possible to assign a different name to the 5 GHz network on the "main" network....but not on the "guest" network, which is the original question that you asked.

     

    So, the 2.4 GHz and 5 GHz bands on the "main" network would have different names and you could "point" devices to only connect to a specific band.

    Sorry, I don't have an answer for you on your other streaming question.

    The internet options screen I get to doesn't have the two boxes for 2.4 and 5.0 GHz at the bottom. It has a check box for the 5.0 network name only.

    The 2.4 GHz and 5 GHz listings have nothing to do with assigning a separate name to the 5 GHz network.

     

    Your screenshot might look like this if you are using AirPort Utility version 5.x:

    So, enter a check mark in the box next to 5 GHz Name.

     

    Example......your network might now be named something like Macallanswireless.  So, both the 2.4 GHz and 5 Ghz bands are using the same name.

     

    Enter a check mark in the box next to 5 GHz Name

     

    Now, the 5 GHz network will be named Macallanswireless (5 GHz).

     

    So, now your 2.4 GHz network is still named Macallanswireless

     

    and your 5 GHz network is now named Macallanswireless (5 GHz).

     

    Your 2.4 GHz capable devices will automatically connect to the 2.4 GHz network named Macallanswireless.

     

    Any 5 GHz capable devices can be directed to connect to the 5 GHz network named Macallanswireless (5 GHz)
