First try rebooting the main Q box and then when this is completely back up and running reboot the minis. To reboot press Standby on your Sky Q remote (if the box responds to the remote), and then switch off and unplug at the mains. Wait at least 30 secs and then Plug back in and switch your Sky Q box back on at the mains. Wait for the on screen instructions to disappear and the front led to turn Amber. Then wait for 30 secs before you press Home on your Sky Q remote or if this is not working press the standby button on the front of the Q box (Amber led)
note: some features may take up to 5 minutes to return.
Reboot the minis as above. If a mini still does not connect reliably try a Network Reset on the minis. Start with the one nearest to the main Q box Network Reset found in mini Home - Settings - Setup - Network. Highlight Status and then select Reset on the right hand side. Follow instructions to WPS with main Q box. You will be asked to press the WPS button on the main Q box (not the mini as the Network reset will start the mini WPS automatically).
If you are on Sky Broadband and the Router is nearer to the mini than the main box then you can try pressing WPS on the router instead of the main Q box. If you do this make sure you press the Sky router WPS button and not the router reset button. If you get the first mini connected then for other minis use WPS on the nearest Q device (main Q box or Sky Router if on Sky Broadband or previously connected mini).
Failing all of the above you may need a Sky Q WiFi Booster to position midway between your main Q box and the mini and you will need to contact Sky directly.
3 ) I have rebooted the whole system.: still nothing.
To clarify; switch off both the main box and the Minis at the plug. Wait a minute before restarting the main box, and then wait,until it has fully restarted before turning on the Minis.
