Wifi для Ubuntu 12.04.1 на Beaglebone

У меня Beaglebone, на котором работает Ubuntu 12.04.1 LTS с USB-ключом Realtek Wifi:

ubuntu@arm:~$ lsusb
Bus 001 Device 001: ID 1d6b:0002 Linux Foundation 2.0 root hub
Bus 001 Device 002: ID 0bda:8176 Realtek Semiconductor Corp. RTL8188CUS 802.11n WLAN
Bus 002 Device 001: ID 1d6b:0002 Linux Foundation 2.0 root hub

Я могу нормально подключиться к своему Netgear R6300 с помощью следующего файла / etc / network / interfaces :

auto lo
iface lo inet loopback

# WiFi Example
auto wlan1
iface wlan1 inet dhcp
    wpa-ssid "FalkorSystems"
    wpa-psk  "<omitted>"

Однако я пытаюсь подключиться к своему устройству Verizon MiFi "Jetpack 4260L", и мне не повезло. Я могу нормально подключиться к MiFi с моего Mac. MiFi настроен с WPA2, точно так же как Netgear R6300

auto lo
iface lo inet loopback

# WiFi Example
auto wlan1
iface wlan1 inet dhcp
       wpa-ssid "FalkorMifi"
       wpa-psk  "<omitted>"

Я также пытался настроить MiFi с открытой сетью, и я использовал:

auto lo
iface lo inet loopback

# WiFi Example
auto wlan1
iface wlan1 inet dhcp
       wireless-ssid "FalkorMifi"

У меня также есть создал точку доступа на моем Mac, используя инструкции здесь:

http://www.dummies.com/how-to/content/how-to-make-your-mac-a-wifi -access-point.html

, и я создал его без какого-либо шифрования, и я не смог подключиться.

Я бы сделал:

> ifdown wlan1
> ifup wlan1

и команда ifup зависнет.

Я также пытался перезагрузиться, а не делать ifdown / ifup.

dmesg сообщит мне, когда он успешно подключится к моему Netgear:
