You have shown only a portion of your /e/n/i. Back it up anyway and
write a new one having only the lo and eth0 interfaces.

Purge wpa_supplicant, ifplugd and guessnet. Reinstall wpa_supplicant.

Add

   allow-hotplug wlan0
   iface wlan0 inet manual
  	   wpa-roam /etc/wpa_supplicant/wpa-roam.conf

to /e/n/i.

In /etc/wpa_supplicant/wpa-roam.conf have

   ctrl_interface=/var/run/wpa_supplicant
   ctrl_interface_group=netdev

   network={
	   ssid="xxxxx"
	   psk="zzzzz"
}

Quotes for the psk only if it is ASCII.

Test.

Reinstall ifplugd. Configure and test.

Reinstall guessnet. Configure (id_str in wpa-roam.conf) and test.
