我买了一台不错的新 Ideapad 310，但我遇到了 wifi 问题。我知道这不是卡本身的问题，因为它在 Windows 下运行良好。
一些控制台输出：

我怀疑“直接固件加载失败”是问题的一部分！我也尝试过从 github repo 安装驱动程序，但无济于事。
如果我拔掉网线，让 wifi 接管，它就能看到周围的各种网络，并尝试连接，然后再次显示密码对话框（是的，我仔细检查过密码是否正确！）。更烦人的是，如果我这样做，然后重新插入以太网电缆，它不会切换回有线，我最终不得不重新启动。
如果我这样做的话，dmesg 中的内容如下：

任何想法或建议都非常感谢。根据这次讨论错误消息可能表示驱动程序无法找到要上传的固件。是否可以增加日志级别，以便打印尝试加载的位置？
编辑：可能只是成为已知错误。是时候用便宜的 USB 加密狗来渡过难关了。
