Follow these steps how to reset the WiFi connection and reconnect the Smile P1 to WiFi:
1 - Delete the network settings (optional)
Press the black button on the Smile P1 for 5 seconds: the middle (STATUS) light flashes 5 times, the top light (WLAN) then flashes quickly. The network settings are deleted. Wait until the Smile P1 has restarted; the middle (STATUS) and top (WLAN) lights blink regularly.

The fastest way to connect the gateway to the internet is WPS (if the router supports it), as also explained in the instruction video above.
First you activate WPS on the router, and shortly afterwards you activate WPS on the Smile P1, by pressing the black button for 2s. The gateway will be automatically connected to the wifi. As soon as the gateway is connected, the WiFi LED will flash (communicate) irregularly fast, then the gateway will automatically restart once.
