So...... that means Chromecast won't work with an Airport Express at all? Is that the end of the story? I kindof figured omething like that because I couldn't find any detail that made the distinction in settings. Maybe I'm taking you too literally, but is it possible to isolate to 2.4 GHz on the main network if not the guest?
Disappointing to say the least, and nobody at Google seems to know that. At least I guess they don't get enough input to make it a known issue. They DO show a known issue with "first generation" Airports (mine's a second gen, so I was hoping) but indicate that it's a matter of selecting the band............. which is wishful thinking I guess.
is there anything else on the market to stream something like Netflix from a laptop to a TV............... that doesn't have a monthly fee? I believe Roku will do it but that we'd have to have a separate paid Netflix account for it and can't use our son's account on which we're a guest.
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.
AirPort Utility > Edit > Wireless Tab > Wireless Options > 5 GHz Name
Sorry, I don't have an answer for you on your other streaming question.
I really do thank you for your response, and I may be just under the pay grade for some of this, so please bear with me.
The Airport Utility screen I get to, following your lead to separately name the 2.4 and 5.O channels, is different from your screen shot. 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. No obvious way to split the channel to two names.
Tried converting a screen capture to an uploadable format but that seems to be above my pay grade as well.
Seems like we're getting closer and closer to returning the Chromecast. Just seems silly for a device that's supposed to be so simple.
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)
