ESP8266 Can't connect to WIFI network and can't work as access point

### Problem Description
I used the WiFiAccessPoint example and I couldn't find the network using both laptop and mobile phone.

I tried to run the WiFiScan example to check if the hardware is working or not. The ESP couldn't find my wifi, phone hotspot. But it only finds mobile hotspot created from laptop. I checked the router and confirmed that the router is working on 2.4 GHz not 5 GHz.

I tried the HelloServer example with my wifi network name (which is couldn't be found in the Scan example) and the status is WL_DISCONNECTED for sometime and then WL_NO_SSID_AVAIL.

I tried the HelloServer example with hotspot created from the laptop (which is found in the Scan example) and the status is WL_DISCONNECTED for sometime and then WL_CONNECT_FAILED.

What is the issue and how to fix it ? Or how o debug this kind of issues ?

Note:
I'm using Core version 3.0.2, Nodemcu with ESP8266 and Arduino IDE.
I also tested 3.0.0, 2.7.2, 2.4.2 and all of them not working too.
