升级到 Ubuntu 22.04.3LTS 时安装 WiFi 驱动程序时出错

我的 HP-ab516tx 笔记本电脑上的 WiFi 与 Ubuntu 18.04 配合得很好。然后我更新到 20.04，我的 WiFi 却无法使用。我的可见网络列表是空的。我在 Github 上找到了现在已删除的 rtlwifi_new 驱动程序，适用于我的 rtl8723be这里。它安装得很好，我的 WiFi 又能用了。当我升级到 22.04 并尝试再次安装它以恢复我的 WiFi 时，我收到一个错误。以下是 的输出make。我该如何修复此错误以及是什么原因造成的？

这是lspci输出。

答案1

您的无线信息报告中有几项令人担忧。首先，模块参数有两个相互竞争且可能不必要的声明。我建议将它们全部删除。

sudo rm /etc/modprobe.d/50-rtl8723be.conf
sudo rm /etc/modprobe.d/rtl8723be.conf

接下来，netplan 设置不正确。

sudo nano /etc/netplan/01-network-manager-all.yaml

添加以下行：

# Let NetworkManager manage all devices on this system
network:
  version: 2
  renderer: NetworkManager

Netplan 对间距和缩进非常严格，因此请仔细校对两遍。保存（Ctrl+o 后按 Enter）并退出（Ctrl+x）文本编辑器。然后执行以下操作：

sudo netplan generate
sudo netplan apply

resolv.conf 设置不正确。

sudo rm /etc/resolv.conf
sudo ln -s /run/systemd/resolve/stub-resolv.conf  /etc/resolv.conf

您没有 8192eu 设备，因此让我们删除它的声明：

sudo nano /etc/modules

删除 8192eu 行。按上述方法保存并退出 nano。

重新启动，断开 USB 以太网，看看网络管理器是否接管无线。无论如何，让我们看看：

sudo dmesg | grep rtl

编辑：您可能需要驱动程序参数。请执行以下操作：

sudo modprobe -r rtl8723be
sudo modprobe rtl8723be ant_sel=1

有改善吗？如果没有，请用 重试该序列ant_sel=2。告诉我们哪些方法可以改善信号强度，我们将写入一个文件以使其持久。
