jduffy they have this temporary 2.4Ghz WiFi for 10 min in order to make possible to you configure the 2.4 devices. In previous updates, when I activate this, my phone would lose connection then return on a same-mane-WiFi 2.4, making possible for set your appliances to your WiFi. But now the phone lose connection and don't reconnect automatically because your 2.4 WiFi has a new name, a no-name-2.4-temporary-WiFi. If I click on this blank-10min-WiFi (as on the pic of the question), it would ask me a password. If I input my dual band wifi password, it will enter. But I can't set the other devices, because they don't find it. And even if they would, I think they wouldn't be able to reconnect when the WiFi changes to your dual band name because they would have been set to a "no-name-WiFi", not no your named WiFi (eg. "Apt1234").

Rbagwill when you temporary pause your 5.0, your 2.4 keeps the same name? If keeps, I really don't know why it's not working for you. If it's happening the same that it's happening with me, then I still don't know what to do. I'm planning on buying a robot for my cat and another for cleaning my house. If they don't fix this till there (and I saw that there are things here that they don't fix even in 4y), I think that the solution would be buying another router.

mikegoldnj what happened was that I called Frontier, they didn't find a solution, so they changed my eero modem for a new one (eero as well). Now thighs are working fine!
