Bionic Beaver 无法识别 wifi 适配器

我已经在型号为 15-da0012dx 的 HP 笔记本电脑上安装了 Ubuntu 18.04.2 LTS。Ubuntu 无法识别内部 wifi 适配器。设置显示“未找到 Wi-Fi 适配器”。

这款产品确实有一个内置 wifi 适配器；我以前在预装操作系统时使用它。HP 将其描述为“802.11b/g/n (1x1) Wi-Fi® 和 Bluetooth® 4.2 组合”。（完整制造商规格请访问https://support.hp.com/gb-en/document/c05997533

行动： lspci -v | grep -i 网络

预期的： 所有网络适配器列表，包括 wifi

答案1

这个解决方案对我有用：
1.按照以下说明从 rtlwifi_new git 安装驱动程序https://askubuntu.com/a/1018851/300665。2
. 关闭 Ubuntu，进入 UEFI BIOS 配置页面，并禁用安全启动，如评论中所建议。3
. 启动 Ubuntu 并测试 wifi。效果很好。

前：

sudo lshw -C network
    ...
  *-network UNCLAIMED
       description: Network controller

       vendor: Realtek Semiconductor Co., Ltd.

       version: 00

       capabilities: pm msi pciexpress cap_list
       configuration: latency=0
       resources: ioport:3000(size=256) memory:b1000000-b100ffff

后：

sudo lshw -C network
    ...
      *-network
       description: Wireless interface
       product: Realtek Semiconductor Co., Ltd.
       vendor: Realtek Semiconductor Co., Ltd.

       capabilities: pm msi pciexpress bus_master cap_list ethernet physical wireless
       configuration: broadcast=yes driver=rtl8723de driverversion=4.18.0-25-generic firmware=N/A latency=0 link=no multicast=yes wireless=IEEE 802.11
       resources: irq:130 ioport:3000(size=256) memory:b1000000-b100ffff
   ...

这似乎不是一个最佳的解决方案，因为我必须禁用安全启动。
