ESP8266 does not detect wi-fi home SSID

[rugg773@gmail.com]

Hallo, my ESP8266 does not detect the SSID of my home wi-fi. I tryed to switch on my iphone hot spot and I can see and connect properly (I also suceed in connecting to MQTT). Instead no way to see my home wi-fi.
I have a TIM HUB gateway Technicolor AGHP sw version AGTHP_2.2.0. I have active a 2.4 GHz and a 5 GHz band (same SSID and pwd) and a guest 2.4 GHz band (different SSID from previous and different pwd). SSID broadcasting is activated, crittography is WPA2 PSK, channel amplitude 20/40 Auto, standard 802.11b/g/n, channel 1 for both 2.4 GHz.
With the scan I see also the wifi from my neighbours but not mine!
Can you help me?
Thx a lot.

I wanted to reply, Just so you know someone has actually read your post. Can you put your startup code here. I had an issue back when I upgraded from 2.1.0 where some new Wifi features were added along with calibration which may be the cause. I am not certain but taking a peak will help.
