我购买了 dlink dwa-131 无线 USB 适配器。但我无法启动它。我在支持的硬件列表中看到，这是 Ubuntu 上的即插即用设备。
我看到了无线故障诊断程序并获取了日志。我已将其粘贴在日志下方。我还看到 lsusb 中列出了 dlink。但它未出现在下面的日志中。板载 Intel pro 芯片组无法正常工作。因此我买了这个加密狗。
我无法粘贴日志，因为出现错误，我需要 10 点声誉才能发布超过 2 个链接。因此，我删除了日志中的链接。

答案1
你可以读一下文章然后尝试：
sudo modprobe rtl8192cu swenc=1
echo "2001 330D" | sudo tee /sys/bus/usb/drivers/rtl8192cu/new_id
答案2
我的 D-link Wifi 加密狗具有以下规格：
- D-Link 无线 N300 Nano USB 适配器
- 型号：DWA-131
- 硬件版本：E1
- 固件版本：5.00
这是我在网上搜索了很长时间之后所做的：
1）前往http://support.dlink.com.au/Download/download.aspx?product=DWA-131并在“版本 E”部分（位于页面顶部）下载文件“DWA-131 Linux 驱动程序 v4.3.1.1.zip (5.88 MB)”。2) 将文件移动到您选择的目录，解压并切换到您刚刚解压的目录。这是（在您选择的目录中）：
- tar -zxvf 20140812_rtl8192EU_linux_v4.3.1.1_11320.tar.gz
- cd 20140812_rtl8192EU_linux_v4.3.1.1_11320/
3）输入以下命令：
- 制作
- su（需要输入密码）
- 进行安装
你甚至不需要重启电脑。就我而言，它立即就起作用了。
我希望这个信息对您有所帮助。

您是否尝试过按下电源按钮左侧的按钮，看看它是否启用了 wifi，它是图片中的 #2。如果它按设计工作，它至少应该切换硬阻止rfkill list all
