为什么 UbuntuMATE 中的驱动程序未认领我的 WiFi 卡？

Question

我的 Realtek 802.11n WiFi 卡未被驱动程序认领这里。我使用install.sh解压的tar.gz. UbuntuMATE 在 Raspberry Pi 2 上运行。

*-usb:4 UNCLAIMED
             description: Generic USB device
             product: 802.11n NIC
             vendor: Realtek
             physical id: 5
             bus info: usb@1:1.5
             version: 2.00
             serial: 00e04c000001
             capabilities: usb-2.10
             configuration: maxpower=500mA speed=480Mbit/s

上图是终端的结果sudo lshw，显示了无人认领的USB设备，即WiFi卡。

运行lspci（我什至不确定这是否相关）给出：

pcilib: Cannot open /proc/bus/pci
lspci: Cannot find any working access method

运行install.sh出现错误：

由于我总体上是 Linux 新手，所以我不知道从这里到哪里去，所以我将不胜感激任何帮助。如果您需要更多信息，请询问，我会发布。

我刚刚发现你的芯片实际上是rtl8192eu.据我所知，Ubuntu 的仓库中没有它的驱动程序。然而，正如 v0yAgEr 在 OSMC 论坛上提到的，该芯片有适用于内核版本 3.18 的驱动程序在 GitHub 上。我将 v0yAgEr 的教程修改为希望对您有用的方式：

1. 安装build-essential：

   • 从可以访问 Internet 的计算机，转到Ubuntu 软件包，下载build-essential，其依赖项及其依赖项的依赖项到名为的文件夹bldessen
   • 将该文件夹复制到您的 Pi，然后安装所有 debssudo cd bldessen && dkpg --install *.deb

2. 从 GitHub 下载驱动程序（单击下载邮编按钮），复制到你的 Pi，然后解压：unzip rtl8192eu-master.zip

3. 编译你的驱动程序：

   cd rtl8192eu-master
   make ARCH=arm
   sudo make ARCH=arm  install
   sudo bash -c 'echo "options 8192eu rtw_power_mgnt=0 rtw_enusbss=0">/etc/modprobe.d/8192eu.conf'
   

4. 测试驱动是否加载：

   modprobe 8192eu
   modinfo 8192eu
