Eu tenho um Beaglebone rodando o Ubuntu 12.04.1 LTS com um dongle USB 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
Eu consigo me conectar muito bem ao meu Netgear R6300 com o seguinte arquivo / etc / network / interfaces:
auto lo
iface lo inet loopback
# WiFi Example
auto wlan1
iface wlan1 inet dhcp
wpa-ssid "FalkorSystems"
wpa-psk "<omitted>"
No entanto, estou tentando conectar-me ao meu dispositivo Verizon MiFi "Jetpack 4260L", e não estou tendo sorte. Consigo me conectar bem com o MiFi do meu Mac. O MiFi é configurado com WPA2, assim como o Netgear R6300
auto lo
iface lo inet loopback
# WiFi Example
auto wlan1
iface wlan1 inet dhcp
wpa-ssid "FalkorMifi"
wpa-psk "<omitted>"
Eu também tentei configurar o MiFi com uma rede aberta e usei:
auto lo
iface lo inet loopback
# WiFi Example
auto wlan1
iface wlan1 inet dhcp
wireless-ssid "FalkorMifi"
Eu também criei um ponto de acesso no meu Mac usando as instruções aqui:
e eu criei sem criptografia e não consegui me conectar.
Eu faria:
> ifdown wlan1
> ifup wlan1
e o comando ifup seria interrompido.
Eu também tentei reiniciar em vez de fazer ifdown / ifup.
o dmesg me diria, quando se conecta com sucesso ao meu Netgear:
