I have a RE603X that is connected to my network and to the internet. I can connect to the 2.4G and 5G extended networks with a Dell XPS laptop running Windows 10 but not with an iPhone 12 Pro or a most recent model iPad Air. Both Apple devices are updated to the latest OS and both can see the extended networks but they never connect. I just get the "spinning wheel" with every attempt.
Both Apple devices are supposed to support WiFi 6. Any suggestions?
