What Ethernet example do you use? If you want to have Ethernet and Wifi, you need to initialize Ethernet and Wifi. Ethernet examples initializes only Ethernet.

Hii ESP_ondreg,
thanks for support i used eth2AP example which given in the ethernet ,its working fine i select DP83848 and gpio change ,but
insufficient TX buffer size and WiFi send packet failed,
i enlarge buffer size than also sometime this error will come.

Yes, this can happen since Ethernet has greater throughput (is faster interface) than WIFI. You did the right thing, it will help you to buffer peaks but cannot solve issues with constant heavy traffic. You can also check other tips here: https://github.com/espressif/esp-idf/tr ... leshooting

I am sorry but I don't follow... Could you please try to split it to multiple bullets what connections are expected where? Or providing a figure with expected topology would be even better. Thanks.
