Raspbian版本 2014-01-07-wheezy-raspbian.img 下载地址为http://cdn.lyq.wiki/res/8188eu-20140616.tar.gz 首先固网链接树莓派，通过SSH登录 wget http://cdn.lyq.wiki/res/8188eu_31024_614.zip unzip 8188eu_31024_614.zip sudo mv 8188eu.ko /lib/modules/`uname -r`/kernel/drivers/net/wireless sudo chown root:root /lib/modules/`uname -r`/kernel/drivers/net/wireless/8188eu.ko sudo mv rtl8188eufw.bin /lib/firmware/rtlwifi/ sudo chown root:root /lib/firmware/rtlwifi/rtl8188eufw.bin sudo depmod -a sudo modprobe 8188eu 然后编辑/etc/netwok/interfaces，添加以下内容 allow-hotplug wlan0 auto wlan0 iface wlan0 inet manual wpa-roam /etc/mywpa.conf iface default inet dhcp 新建mywpa.conf写入链接配置vi /etc/mywpa.conf network={ ssid="YOUR SSID" proto=RSN key_mgmt=WPA-PSK pairwise=CCMP TKIP group=CCMP TKIP psk="YOUR PASSWORD" } 重启系统
