@Wayne-TP Thanks for your answer. Light was orange. After I disconnect the Ethernet wire, resumes the WiFi connection for some hours, but sooner or later turns out to orange. Wifi Signal is the best...

@Wayne-TP Can I downgrade to previous firmware?

@Wayne-TP My hub have been working really well until this update. After that, keeps disconnecting from my 2.4Ghz wifi network. Once I connect the ethernet wire, hub got connected again.
