sudo modprobe r8712u什么也没做，这是iwconfig的结果：

谢谢
我下载并安装了这个驱动程序（来自zip）： https ： //github.com/lwfinger/rtl8188eu它工作正常。
您的设备的正确驱动程序不是您安装的驱动程序，而是r8712u：
modinfo r8712u | grep 3300 alias: usb:v07D1p3300d*dc*dsc*dp*ic*isc*ip*in*
它默认包含在13.04中。 请尝试加载它：
sudo modprobe r8712u
有任何错误或警告吗？ 是否创建了无线接口？
iwconfig
如果没有，请在此处查看线索：
dmesg | grep r87
如果只是加载它会使您的设备工作，添加要自动加载的模块：
sudo -i echo r8712u >> /etc/modules exit
