那么，这是否意味着驱动程序安装成功？但 iwconfig 再次没有给出 wlan0 的信息。请帮帮我，不要再回到 Windows 了……
答案1
您已正确安装 rtl8192cu 驱动程序，但未创建无线接口，因为 rtl8192cu 不适合您设备。请获取临时有线以太网连接并执行以下操作：
sudo apt-get install git
git clone https://github.com/purchae/rtl8188eu.git
cd rtl8188eu
make
sudo make install
sudo modprobe -r rtl8192cu
sudo modprobe 8188eu
当更新管理器安装了更高版本的内核时，在需要重新启动后，重新编译：
cd rtl8188eu
make clean
make
sudo make install
sudo modprobe 8188eu
答案2
我有相同的 D-Link DWA-125 rev.D1，但是
lsusb
印刷
...
Bus 001 Device 005: ID 2001:3310 D-Link Corp.
...
（注意身份证号）
为了使其工作，我更改了文件rtl8188eu/os_dep/usb_intf.c
- {USB_DEVICE(0x2001, 0x330F)}, /* DLink DWA-125 REV D1 */
为了：
+ {USB_DEVICE(0x2001, 0x3310)}, /* DLink DWA-125 REV D1 */
保存
sudo make
sudo make install
sudo modprobe -r 8188eu
sudo modprobe 8188eu
现在驱动程序可以帮我工作了 :)
答案3
非常感谢你。驱动程序终于安装好了。唯一的问题是加密狗不能正常工作：经过 7-10 秒的下载-无任何内容或互联网上无任何内容后，托盘中的图标显示“无信号”，ping 值无限大。

我只是在个例中提到，如果我开始下载一些非常大的东西，只要下载过程持续，我的好网络就存在。我做错了什么？顺便说一句，在 Windows 上它运行完美。
