Using the Google Home app on my Galaxy S9+, I cannot find my 5G network setting up Chromecast Audio. I enter it manually but get Retry message. But when I give up and start reconnecting to 2.4 I seem to be connected to 5G.

Afaik CCAudio can use either network so I don't understand why the 5G doesn't appear as an available choice. It certainly does on both my laptops and for my Googletv.

5G or 5Ghz Wi-Fi ? These are 2 very different technologies

Pardon my shorthand. Thought the clue might be there in my ref. to 2.4.

Of course I know the difference.

Pretty clear from the context.

It may depend on the authentication you're using for your wifi. Try setting up a new SSID only using 5Ghz radio, with open authentication, and see if it connects. Then try securing it and reconnect. If that all works then your original SSID settings might not be right for the device to connect (e.g. WPA version, device isolation, etc).

Which is actually fine. I have several distinct networks at home. One dedicated to 5ghz, one dedicated to 2.4ghz (generally for IoT), and one that covers both so guests can connect when they visit.

Something weird going on. Always told that Casting device has to be on the same wifi network as source but currently playing Tidal from my phone which is on 5G to Chromecast Audio which(according to Home app) is on 2.4??????????????

Check which channel you are on and its not a DFS one as those suck for IOT things which dont have all the compliance stuff done to use them.

Same network, not the same wifi. Its usually dumbed down to same wifi to allow for a reason to tell people that insist on using wifi extenders that is why its not working rather than having to explain to them that they have 2 networks.

It will also work between networks if you have a router that does mDNS between the networks. I have even had it group playing when one was on my iot network and one was on the main network when I had everything allowed between them.

Same network can have multiple frequencies, that is what I described earlier. It also sounds now like you may have a frequency prioritisation setting you need to enable. If you want 5ghz capable devices to always connect at 5ghz on a network that is both 2.4/5ghz, then there is sometimes a setting in the router to force that to happen. Otherwise, do what I said earlier and set up a separate 5ghz only network, and have all your 5ghz devices connect to that. You'll get other issues though, like if you are down the other end of the house your 5ghz signal will suffer, 2.4ghz has better range in a typical home.

Thanks for the enlightenment.

As mentioned, ensure the devices are on the same network (it doesn't matter if one is on 5 GHz band and another on 2.4 GHz). Also important is to make sure your router is not set for Network Isolation, which will block devices on Wi-Fi from seeing each other.
