不可一日無煙卷

樹莓派使用usb無線適配器

wireless adapter必須是樹莓派支持的,可以到官方或者 http://shumeipai.net 查看硬件列表 兩種方案,一種不行換另一種 # 方案一 ## 配置網絡接口 sudo nano /etc/network/interfaces 文件內容默認如下: auto lo iface lo inet loopback iface eth0 inet dhcp allow-hotplug wlan0 iface wlan0 inet manual wpa-roam /etc/wpa_supplicant/wpa_supplicant.conf iface default inet dhcp 修改如下: DHCP配置: auto lo iface lo inet loopback iface eth0 inet dhcp allow-hotplug wlan0 auto wlan0 iface wlan0 inet dhcp wpa-roam /etc/wpa_supplicant/wpa_supplicant.conf STATIC配置: auto lo iface lo inet loopback iface eth0 inet dhcp allow-hotplug wlan0 iface wlan0 inet manual address 192.168.0.100 netmask 255.255.255.0 gateway 192.168.0.1 wpa-roam /etc/wpa_supplicant/wpa_supplicant.conf ## 設置WPA認證 sudo nano /etc/wpa_supplicant/wpa_supplicant.conf 修改如下: network={ ssid="SSID名稱" proto=RSN key_mgmt=WPA-PSK pairwise=CCMP TKIP group=CCMP TKIP psk="密碼" } ## 重啟,wlan0會自動開啟 # 方案二 ## wpa認證文件 sudo nano /etc/wpa_supplicant/wpa_supplicant.conf 修改內容如下 ctrl_interface=DIR=/var/run/wpa_supplicant GROUP=netdev update_config=1 network={ ssid="SSID名稱" proto=RSN scan_ssid=1 key_mgmt=WPA-PSK pairwise=CCMP auth_alg=OPEN psk="密碼" } ## 修改interfaces配置 sudo nano /etc/network/interfaces DHCP配置: auto lo iface lo inet loopback iface eth0 inet dhcp allow-hotplug wlan0 auto wlan0 iface wlan0 inet manual wpa-roam /etc/wpa_supplicant/wpa_supplicant.conf iface default inet dhcp STATIC配置: auto lo iface lo inet loopback iface eth0 inet dhcp allow-hotplug wlan0 iface wlan0 inet manual address 192.168.0.100 netmask 255.255.255.0 gateway 192.168.0.1 wpa-roam /etc/wpa_supplicant/wpa_supplicant.conf iface default inet dhcp ## 重啟 默認會自動連上可以運行 `sudo iwconfig` 查看配置或者`sudo ifconfig`查看狀態
