Couldn’t connect via wireless today

[HobGoblyn]

Woke up this morning, wired connections all fine, unable to connect via wireless on any device.

Rebooted router, exactly the same.

Its a Hub 3.0

Logged into the router and under Wireless Signal, Smart Wi-Fi was enabled and everything under 5 GHz was greyed out.

I disabled Smart Wi-Fi (Disable Channel Optimisation) and the 5G settings were no longer greyed out and all the wireless devices connected fine.

So problems fixed for now, just wondered why I needed to do this?

thanks

We have a Hub 3 and for comparison below are our Wireless Settings which give a stable service  :
