树莓派配置USB无线网卡

1、lsusb或者ifconfig -a查看网卡是否识别wlan0

root@raspberrypi:/etc/network# lsusb
Bus 001 Device 004: ID 0bda:8179 Realtek Semiconductor Corp. RTL8188EUS 802.11n Wireless Network Adapter
Bus 001 Device 003: ID 0424:ec00 Microchip Technology, Inc. (formerly SMSC) SMSC9512/9514 Fast Ethernet Adapter
Bus 001 Device 002: ID 0424:9514 Microchip Technology, Inc. (formerly SMSC) SMC9514 Hub
Bus 001 Device 001: ID 1d6b:0002 Linux Foundation 2.0 root hub

　　

2、配置/etc/network/interfaces，添加以下内容

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

　　

3、生成无线网络认证信息

root@raspberrypi:/etc/network# wpa_passphrase WANG wangwang


network={
ssid="WANG"
#psk="wangwang"
psk=4310d6982d9a5fb811d6341ef0c697e8ce0978e036a8d12f557f3a0633d92fef
}

　　

上边生成信息填写到 nano /etc/wpa_supplicant/wpa_supplicant.conf

4、配置静态IP，需编辑nano /etc/dhcpcd.conf ，填写如下内容

interface wlan0
static ip_address=192.168.100.88/24
static routers=192.168.100.1
static domain_name_servers=116.116.116.116 223.5.5.5
