Ring flood, indoor cams + Mesh network

Good morning. I added an ASUS WiFi 6 mesh router and mesh nodes to our network, replacing our old router and WiFi. When I went to go bring my Ring cameras up on the network, only my Ringo Pro doorbell would join. I could not get either of the indoor stick up cameras to join, nor the Ring flood. During setup it gets to the point where it asks you to join the specified Ring setup signal, but it won’t allow me to join that network on any of the three devices. I saw somewhere where it said that Ring devices won’t join a 5G network, so I specified a 2.4 network and it wouldn’t not join. I did some reading and it said to create a guest network to avoid the firewall issues and I did that, but still wasn’t able to join. I’m not super tech savvy, but I’ve done all the troubleshooting I can find. Any advice on what I may be doing wrong?
