Dear all, thank you for all your great work!

I'm aware that esp8266 is 2.4GHz band only. I don't understand though what prevents esp8266 from connecting to a dual-band router. I'm seeing my other 2.4GHz-only devices successfully being connected to the same ssid. So why does not it work for esp8266 exactly? Is it a hardware limitation or maybe a logical issue in the esp wifi software published here?

They electricity is maybe low so that the router is connect with the capacity of electricity

Try forcing the ESP to use only 802.11g and not 802.11n Some router/access points try to steer clients to another band (literally called band steering) by shortly disconnecting the client. It seems like routers might not do this when a device only claims to support 802.11g as this band steering feature is unknown to devices not supporting 802.11n
