為什麼我的 WiFi 卡沒有被 UbuntuMATE 中的驅動程序認領？

我的 Realtek 802.11n WiFi 卡沒有被這裡的驅動程序認領。install.sh我使用解壓文件中給出的腳本安裝了驅動程序tar.gz。UbuntuMATE 在樹莓派 2 上執行。

*-usb:4 UNCLAIMED
            description: Generic USB device
            product: 802.11n NIC

上面是sudo lshwin終端的結果，顯示了無人認領的USB設備，WiFi卡。

執行lsusb：

執行lspci（我什至不確定這是否相關）給出：

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

執行install.sh給出錯誤：

由於我一般是 Linux 新手，所以我不知道從這裡去哪裡，所以我很感激任何幫助。如果您需要更多資訊，請詢問，我會發布。

我剛剛發現你的晶片實際上是rtl8192eu. 據我所知，Ubuntu 的 repo 中沒有它的驅動程序。但是，正如 v0yAgEr 在 OSMC 論壇上提到的那樣，該晶片的驅動程序適用於 GitHub 上的核心版本 3.18 。我修改了 v0yAgEr 的教程，希望對你有用：

1. 安裝build-essential：

• 從可以訪問 Internet 的電腦上，轉到Ubuntu Packages，將build-essential其依賴項及其依賴項的依賴項下載到一個名為bldessen
• 將該文件夾複製到您的 Pi，然後通過以下方式安裝所有 debsudo cd bldessen && dkpg --install *.deb

2. 從 GitHub 下載驅動程序（點擊下載 Zip按鈕），複製到您的 Pi，然後將其解壓縮：unzip rtl8192eu-master.zip
3. 編譯你的驅動程序：

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. 測試是否載入了驅動程序：

modprobe 8192eu
modinfo 8192eu
