Deauth attack won't work

If you see 0 pkts/s on the website then you've made a mistake. Check that you have followed the the installation steps correctly and that the right SDK installed, it must be version 2.0.0! If it can send packets but your target doesn't loose its connection, then the Wi-Fi router either uses 802.11w and it's protected against such attacks, or it communicates on the 5GHz band, which the ESP8266 doesn't support because of its 2.4GHz antenna.

If you have other questions or problems with the ESP8266 you can also check out the official community forum.
