Yes, good point, thank you. I do use separate SSIDs for the two RF bands, just so I can keep track of them. At the moment, that was not the problem. Later, I powered off the Chromecast and restarted it. THAT got it to show up on the Available Device list.
Hey there mayitogl,
I'm just checking up on this thread, do you have any more questions or need any additional help?
Thank you for helping out on this thread, Bigg1 and Ashepherdson!
