Mt7688an is pretty cheap.

Thank you for your information.
Actually we didn't need router function, we just want extend wifi signal from ethernet port.
Is there any other more simply solution?

Well you still have to do L2 frame translation. Why do you want to use an IOT chipset to do this instead of an AP/router chipset?

because the cost. Wifi router chipset is too expensive.

Thank you for schedule.

"As for packet switching, you will probably have to implement this by enabling routing between interfaces in LwIP."
I think we may not need involve in LwIP.
We just need transparent transport the 802.11 frame from wifi port to 802.3 frame of ethernet port.

Thanks for reply.
So could you please give us the detail schedule about Ethernet driver and Wifi AP switch?

Hi All,
ESP32 has both wifi AP function and Ethernet interface.
Does anyone has a ESP32 solution for wifi AP device, with Ethernet interface to plug in a RJ45 port?
It act like a layer two switch, which transparent deliver between wifi/Ethernet, and convert 802.3 to 802.11 frame.
Note, it not ...
