有一種淘寶上賣的樹莓派免驅的無線網卡，芯片是 RTL8188CUS。php

下面是樹莓派 1 代的操做。html

鏈接無線網卡

1 代好像插上 USB 會致使設備重啓，那就等等。linux

首先檢查設備：vim

$ lsusb
Bus 001 Device 004: ID 0bda:8176 Realtek Semiconductor Corp. RTL8188CUS 802.11n WLAN Adapter
Bus 001 Device 003: ID 0424:ec00 Standard Microsystems Corp. SMSC9512/9514 Fast Ethernet Adapter
Bus 001 Device 002: ID 0424:9512 Standard Microsystems Corp. LAN9500 Ethernet 10/100 Adapter / SMSC9512/9514 Hub
Bus 001 Device 001: ID 1d6b:0002 Linux Foundation 2.0 root hub

能夠看到裏面出現了 RTL8188CUS 802.11n WLAN Adapter。網絡

查看無線鏈接

這時候能夠用 ifconfig 看看有沒有 wlan0 出現。less

$ ifconfig
...
wlan0     Link encap:Ethernet  HWaddr e8:4e:06:25:xx:xx
...

能夠查看一下無線網卡可以搜索到的網絡：ide

$ iwlist wlan0 scan

設置無線鏈接

分別兩個文件，大概像下面這樣：工具

$ sudo vim /etc/network/interfaces

# interfaces(5) file used by ifup(8) and ifdown(8)

# Please note that this file is written to be used with dhcpcd
# For static IP, consult /etc/dhcpcd.conf and 'man dhcpcd.conf'

# Include files from /etc/network/interfaces.d:
source-directory /etc/network/interfaces.d

auto lo
iface lo inet loopback

auto eth0
iface eth0 inet dhcp

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

$ sudo vim /etc/wpa_supplicant/wpa_supplicant.conf

ctrl_interface=DIR=/var/run/wpa_supplicant GROUP=netdev
update_config=1

network={
    ssid="your_ssid"
    psk="your_password"
}

重啓無線網絡並檢查

再從新 ifconfig，看看是否是有 IP 地址了。oop

$ ifconfig wlan0
wlan0     Link encap:Ethernet  HWaddr e8:4e:06:25:xx:xx
          inet addr:192.168.1.11  Bcast:192.168.1.255  Mask:255.255.255.0
...

到這裏應該就完成設置了。以後重啓都會自動去鏈接那個 WiFi。學習
