我在 2014 年 Macbook pro 上使用 Debian。我从以下位置安装了 Broadcom 无线驱动程序官方 Debian 维基。
我时不时地会收到此错误，即我的笔记本电脑与 wifi 断开连接，然后无法重新连接。
这是我的 dmesg 日志

我不知道如何解决这个问题，可以采取什么措施来解决这个问题？
答案1
对于大多数人来说，似乎是在暂停/休眠后发生的？我还没有找到明确的答案，但这可能会让你更接近：
看起来可能是类似的东西。
如果我暂停然后恢复，我的无线卡就会停止工作，我必须编写一个小脚本来/etc/pm/sleep.d/删除wl模块然后重新加载它。希望这能以某种方式帮助您！
** 编辑 **
您的系统将卡型号报告为：
[5.372637] wlan0：Broadcom BCM43a0 802.11 混合无线控制器 6.30.223.248 (r487574)
显然，您使用的“wl”驱动程序很容易出现这些随机错误。我找到了具有相同 Broadcom 品牌的其他人，通过卸载“wl”驱动程序并直接安装从 Broadcom 下载的驱动程序解决了问题：（页面为法语，翻译为英语）
祝你好运，请告诉我这是否有效。
答案2
电源管理可能是问题所在。您是否尝试过您在问题中引用的 Wiki 中提供的解决方案：iwconfig wlan0 power off？
