I have recently downloaded Kali 2020.1 on my machine (usb persistence).
Now though I am able to use Wi-Fi but whenever I want to use monitor mode I am not able to discover any APs while there are many.

I was able to use monitor mode and airodump-ng on previous versions.

I tried many solutions but still no luck

I use airmon-ng for monitor mode
and airodump-ng for capturing packets
