Answer 3

1. Try the SSID network name in Latin.
2. DNS was not changed to any "non-advertising" ones?
3. Connect your phone and PC to the network and try to ping them with each other. Is there a package pass?
4. Drop the router to default settings.
Read the instructions for Sonoff in case of emergency. You may be making mistakes. On the off site, the instructions are ancient. According to ewelink, it fits.
