Yes can't wait for it😅

Go strict after this tutorial and everything should work. I think there goes something wrong when you flash you Wifi Dev Board kzbin.info/www/bejne/o5OVYWtup9J5q7cfeature=shared

No, that's not what this is

It's like you kick everyone out of the WI-FI Network

it is possible when you select target type in ''all'' instead of the wifi number

5ghz is a tough one, especially with dual band. Even with Kali Linux people are struggling. WiFi5 and WiFi6 are impervious to deauth attacks unless you use a modded Void11 among other methods, even on a desktop environment it can be difficult. Lots of Kali boys even waiting for ESP-C5 to be released.

Get a laptop/desktop, a dual band network adapter, see if you can send packets. The target you're trying to attack probably is a dual-band network, which means you'll need an WiFi adapter that supports dual-band. If you have one and can send your packets to network and it still won't struggle, this network is not vulnerable to deauth attacks. If its not dual band, and the 2.5 isnt struggling with the laptop, then its simply not venerable to deauth. same test can be done with just the 2.5ghz, if it doesn't struggle then it wont work. If it struggles, the ESP8266 isnt good enough, if you are using an ESP32 try an ESP8266.
