无法使用我的 TL-WN725N

我正在使用 Ubuntu 13.04 3.8.0-27-generic，但无法使用 TL-725N nano 无线适配器。

我安装了这个：https://code.google.com/p/realtek-8188cus-wireless-drivers-3444749-ubuntu-1304/ 但即使重启后也没有发生任何事情。我仍然无法在网络管理器中看到该设备。

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

答案1

我下载并安装了该驱动程序（来自 zip 文件）：https://github.com/lwfinger/rtl8188eu 而且它确实有效。

答案2

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*

它在 13.04 中默认包含。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，请在这里寻找线索：

dmesg | grep r87

如果简单加载就能让你的设备工作，请添加要自动加载的模块：

sudo -i
echo r8712u >> /etc/modules
exit
