Debian jessie 8.5 未检测到无线

我完成了Debian Jessie 8.5的安装，但系统没有检测到无线。我的无线网络是隐藏的，密码为 wpa psk/wpa2 psk，并且我使用的是 Xfce 桌面环境。

你需要安装firmware-realtek

Realtek 有线和无线网络适配器的二进制固件

该软件包包含一些以太网适配器的二进制固件，这些适配器具有 r8169 驱动程序支持的 RTL8111/RTL8168 芯片；以及带有 r8192_pci、r8192s_usb、r8712u、rtl8188eu、rtl8192ce、rtl8192cu、rtl8192de、rtl8192se、rtl8723ae 支持的 RTL8188、RTL8192、RTL8712、RTL8723 和 RTL8821 芯片的无线网卡3au,rtl8723be和 rtl8821ae 驱动程序。

所需的驱动程序是：rtl8723be

1）通过以太网连接

将存储库添加non-free到您的sources.list：

nano /etc/apt/sources.list

然后添加以下行：

deb http://ftp.debian.org/debian/ jessie main contrib non-free
deb-src http://ftp.debian.org/debian/ jessie main contrib non-free

更新并安装 Realtek 驱动程序

apt-get update && apt-get install firmware-realtek

如果您的连接不断断开，请键入以下命令：

echo "options rtl8723be fwlps=0" | sudo tee /etc/modprobe.d/rtl8723be.conf

2) 没有互联网连接：

下载firmware-realtek_0.43_all.deb，使用您的存档管理器将其提取rtl8723befw.bin并/lib/firmware/rtlwifi/rtl8723befw.bin复制到/lib/firmware/rtlwifi：

cp rtl8723befw.bin /lib/firmware/rtlwifi/

重新加载驱动程序：

modprobe -rv rtl8723be
modprobe -v rtl8723be
