Problem with sky booster , no connection light, since a power cut

[Bonsai1]

Tried resetting, power green light on, Wi-Fi green light on, connected light not on

Reboot the main hub and see if re connects the booster. If not then reset the booster by pressing the rear reset button for 20 seconds, then re sync it with the hub by pressing the wps button on the hub and then the wps button on the booster.

Thanks for your help, all sorted, didn't know there was a reboot button on the booster. Thanks again 👍
