Hello
I am to use my ESP32s (NodeMCU32s) as an excess point, I want to connect my ESP32s to my home Wifi Router to get the internet to my ESP32s. Finally I want to connect my Laptop to the AP of ESP32s and use the internet.

I have tried your code (esp32_series_AP+StationMode.ino) from here BUT I get no internet access on my Laptop.

Please help me out ...

Thank you

@MolGupta This code snippet is only for running access point and station mode simultaneously on ESP32, ESP32 will be connected to your wifi router and get the connection and can send data (you have to write code for that for http or mqtt).
there is no bridging done so if you connect your laptop to ESP32 access point you won't get internet on your laptop.
i don't things so this type of bridging is possible in ESP32 but it is possible with the raspberry pi. if you are trying to make your own wifi router use raspberry pi instead.

I was thinking that some simple bridging could be possible (with only one client on ESP32) where ESP32 picks the infor and sents out to the main router since it is already logged on for internet use. Similarly when packets are received from the internet by ESP32 it sends them to the connected client. A simple code in the loop() can keep polling for all these .... (maybe).
