我是 Linux 新手。立即遇到了 wifi 信号非常弱的问题，而我在 Windows 上没有遇到过这个问题。我已经看到了 HP 笔记本电脑的解决方案，但对我来说都不起作用。也尝试过更改内核（我听说 5.15 版本在这种情况下有点问题），但仍然没有用。我得到了以下lshw -C network命令的输出：

我以为更新 WiFi 驱动程序会有所帮助，但遗憾的是没有我可以更新的版本。
如果有人能帮助我将非常感激
更新 1。
终端命令的结果nmcli device wifi list如下。Androidha 是我的手机，我打开了热点，我直接把手机放在笔记本电脑上，但信号仍然远没有达到“强信号”，手机本身连接到了其他 WiFi 之一。另外两个路由器在相邻的房间里。
