In above output, I want to configure "ra0, Ralink STA".  the command 
modinfo mt7601Usta
gives no error.  The driver has been installed in "/etc/Wireless/..."

Gracias de antemano por cualquier ayuda, consejo.

Utilice el wpa_supplicantcomando.

sudo wpa_supplicant -B -i wlan0 -c /etc/wpa_supplicant.conf 

Nota:Noproporcione -D wext/nl80211/cfg80211, ya que el conductor lo toma automáticamente.

Edite /etc/wpa_supplicant.confpara proporcionar su ESSID WiFi y clave de acceso:

ctrl_interface=/var/run/wpa_supplicant
update_config=1

network={
    ssid="YOUR-WIFI-ESSID"
    psk="your-wifi-password"
}
