Raspberry Pi не подключается к скрытому SSID WIFI

У меня проблема с edimax ew-7811un на моем Raspberry Pi. Я пытаюсь подключиться к скрытому SSID, назовем его «hiddenssid» с личным паролем WPA2 «hiddenpassword». Я могу увидеть WiFi ключ в iwconfig. Я создал PSK-версию своего пароля:

$ wpa_passphrase "<Your Wifi SSID>" "<Your Wifi PASSWORD>"

вот мой /etc/network/interfaces:

auto lo

iface lo inet loopback
iface eth0 inet dhcp

auto wlan0
allow-hotplug wlan0
iface wlan0 inet dhcp
   wpa-scan-ssid 1
   wpa-ap-scan 1
   wpa-key-mgmt WPA-PSK
   wpa-proto RSN WPA
   wpa-pairwise CCMP TKIP
   wpa-group CCMP TKIP
   wpa-ssid "hiddenssid"
   wpa-psk pskpassword

iface default inet dhcp

Вот что я получаю, когда набираю sudo ifup --force wlan0:

Не могли бы вы мне помочь?

К сожалению, после sudo ifup --force wlan0, я получаю:
