What is the expected behavior?

connect to wifi smoothly.

What is the actual behavior?

It takes a long time(usually a few minutes) or even impossible to connect to wifi from my router while it can smoothly connect to my hotspot or ap from another esp board.
I wonder what might caused this.

Hi @mushsoooup ,

Could you please share logs with debug-level enabled, sniffer capture, and AP model/configuration to help debug the issue further?

Thanks in advance!
