Tools like airgeddon , wifiphisher and other that perform deauthentication attack does not succeed anymore . Note that if I try to do a manual deauthentication attack using aireplay -ng it works fine . The think is that with these tools I don’t an error or something . Deauth seems to be performed . However it does not succeed . I tried in many different network and with many internet cards . It’s not my internet card’s problem . Please investigate a bit on it
