Recentemente, reinstalei meu sistema operacional e esqueci de fazer backup do arquivo /etc/wpa_supplicant/wpa_supplicant.conf , por isso passei o dia imaginando como me conectar ao Wi-Fi.
Eu posso me conectar a uma rede pública com SSID CUGuest , então acho que meus drivers estão bem, e não há problema com dhcpcd . Em computadores que não são meu laptop, posso fazer logon em uma rede WiFi segura chamada CUWireless usando minha ID de escola JDR74731 e senha ***** ... nenhum arquivo de certificado é necessário.
Eu tenho mexido com arquivos de configuração do formulário
/etc/wpa_supplicant/wpa_supplicant.conf
---------------------------------------
network={
ssid="CUWireless"
key_mgmt=WPA-EAP WPA-PSK IEEE8021X
identity="[email protected]"
password="*****"
disabled=0
}
Eu tento conectar-me ao WiFi usando um comando como
$ sudo wpa_supplicant -B -dd -iwlp3s0 -c/etc/wpa_supplicant/wpa_supplicant.conf -Dnl80211
Depois, eu verifico usando iw dev wlp3s0 link para ver se algo excitante aconteceu ou não, e quando ainda não consigo acessar a rede, eu verifico a saída do comando wpa_supplicant (coloco sua saída em um arquivo de log especificado com o -f flag):
wpa_supplicant v2.6

Isso é o máximo que eu consegui. Mesmo se você não tem idéia do que o problema pode ser, eu adoraria qualquer conselho de depuração sobre isso! Acabei de mexer com wpa_supplicant.conf e espero que, eventualmente, as coisas funcionem, mas estou ficando exausto.

Meu sistema veio com uma cópia do netctl instalado, mas eu o removi. Eu não acho que quaisquer outros conjuntos de redes estejam interferindo com wpa_supplicant . Eu me certifico de sudo killall wpa_supplicant entre todos os meus testes.
