Do your WiFi SSID and/or key contain any special characters or spaces? If they do, modify them and try again.  
Security? What do you mean?

So do you have an idea or recommendations. To keep all my ewelink devices on line I have to turn off 5G and disable the wifi security?

I don’t know what this specific case is on your side. I haven’t come across anything like that personally and I haven’t heard of anyone who had something similar.

Sonoff devices work normally with WPA2-PSK and a 5Ghz radio on the router.

Reset the routers to factory settings and configure everything again, because you seem to have some strange conflict. Maybe you should also think about OpenWrt…
