Debian
Wifi 無法在具有 RTL8723de 驅動程序的 debian 8.9 中工作（10ec:d72310和C:d72310ec:d723)
請幫我讓我的wifi正常工作。過去兩週我一直在研究這個問題，並嘗試了許多解決方法。現在我重新安裝了 Debian 並準備從頭開始。以下是系統網路的詳細資訊。

更新
要安裝
rtl8723de驅動程序，您的核心版本應該 >=4.11。簡單的方法是安裝 Debian Stretch，然後從 backports 升級您的核心版本（核心
4.13可用）要
rtl8723de在 Debian Jessie 上安裝，你應該編譯你的核心 >4.11安裝過程：
驅動程序可以安裝如下：
git clone https://github.com/smlinux/rtl8723de.git cd rtl8723de make make install適用於 Linux 核心版本 5 的 Realtek RTL8723DE 模組：
git clone https://github.com/smlinux/rtl8723de.git -b current dkms add ./rtl8723de dkms install rtl8723de/5.1.1.8_21285.20171026_COEX20170111-1414 depmod -a reboot更新Debian 10
該驅動程序在lwfinger/rtw88上可用：
注意：1）只要發行版沒有修改任何核心 API，此程式碼將建構在任何核心 4.19 和更高版本上。
- 此儲存庫包括以下卡的驅動程序：
RTL8822BE、RTL8822CE、RTL8821CE 和 RTL8723DE
sudo apt-get update sudo apt-get install make gcc linux-headers-$(uname -r) build-essential git git clone https://github.com/lwfinger/rtw88.git cd rtw88 make sudo make install sudo modprobe -rv rtw_8723de sudo modprobe -v rtw_8723de
這裡的非官方 Linux 驅動程序：https ://github.com/smlinux/rtl8723de
請注意，我不是上述驅動程序的作者或貢獻者。我在訂閱 lwfinger 的 rtlwifi-new git 項目頁面時了解了使用者“smlinux”執行的這個項目。
我有一台帶有 RTL8727DE 無線模組的 HP 15-BS576TX 筆記型電腦，該驅動程序執行良好。編譯很簡單；您可以使用 git 複製原始碼，也可以從上面的連結以 zip 格式下載原始碼。
然後，在源目錄（rtl8723de）中打開一個終端並執行以下命令，將 8723de.ko 核心模組安裝到模組目錄中。
make sudo make install && sync; sudo modprobe 8723de就是這樣。擁有這台筆記型電腦幾個月後，終於 Wifi 工作了！不過，社區必須意識到，在 Linux 核心中為該模組提供此驅動程序或其他驅動程序的正式住宿可能需要一些時間。此外，請查看https://github.com/lwfinger/rtlwifi_new以獲取由上述 WiFi 模組製造商 Realtek 提供的任何可用更新驅動程序。
