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

?

1 2 3 4 5

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

?

1 2 3

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

?

1 2 3 4 5 6 7 8

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

?

1 2 3 4

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
