Boosters suddenly cut out

[SuzeR7]

My WiFi and phone cut out briefly yesterday. The phone came back on and the WiFi did after I'd restarted the router. But the two boosters aren't working now - the middle "connected " button is now no longer green. I've tried resetting and moving them nearer to the router, but stil not working

You may need to factory reset both the router & boosters. You can do this by holding the reset button on the Sky hub & Boosters for a minimum of 30 seconds.
