Sonoff switches won't connect

I've upgraded my router, and discovered that none of my devices will now connect to the new one, in Quick pairing mode it won't discover them, and in AP mode, it will discover the devices, but they won't connect, how do I get around this?

Just out of curiosity, is yours a mesh network?

Nope, it isn't

Turn on airplane mode and connect using quick pairing mode (touch).

I can't connect the sonoffs switchs to Wi-Fi. I verified the "10 Solutions to Failed to Connect to the WiFi Router" but the problem persist. I used de pairing proccess and de devices are defined but the status is off line. Do you sugest me another process?

If you cannot connect your device this is due to old first generation hardware that doesn’t work properly with new internet devices because of SSID and PWD combination.

This worked for me with my Android phone in combination with an ASUS RT-AC87U

Create guest network  and name SSID: 12345678 with PWD: abcabcab

Press button on socket 2x 7 seconds in order to let it blink every second.

Pair the device (don’t use compatible AP). After connection update firmware.

Leave the device on for 5 minutes and unplug the socket.

Remove the guest network with SSID: 12345678 and connect with your phone to you own network again. Plug the socket back to the wall plug and press the button on the socket 1x for 7 seconds until it blinks every 3 seconds. On the app select now Compatible Pairing Mode AP.

Now you will see that the device has been recognized as second generation.


Took some time to figure it out but it worked.
