New Hub Firmware v103

How to upgrade the firmware? I can’t find a link to download.
My hub is NOT coming online after initial setup…
My SKY is also offline.
Both air and sky were detected by the app and added, but air is online and sky is offline.

I see my hub connected to my wifi router… I can see the IP inside the admin gui. And even TX rates from hub to wifi are non-zero… So it is connected and communicating… But the app display the hub is offline.
