Wi-Fi sky max hub keep dropping

[JAMBOBRA2011]

Every so often my hub powers off and I lose Wi-Fi this happens many times a day. Sometimes the hub stays on and the Wi-Fi siginal

drops. This can be seen when I'm running the service checker. It is currently configured to use 5ghz only.

@JAMBOBRA2011 Why have you only got the 5Ghz turned on, where you having a signal device problem where the preferred band was 2.4Ghz. About the lights below, and the HUB should not be switching itself off.
