My kids have apple phones and for the last few days I'm having to transfer data ro them I have checked the WiFi booster and it's  not showing connected I did the rest the button but the green light not showing connected still?

So what to do next I can't keep transferring data to them ??

Have you tried factory resetting the router & booster?

Also if your booster has an ethernet port you can often re-link them by temporarily connecting the booster via ethernet to your hub
