WiFi 问题:安装 Ubuntu 14.04 后 /var/log/syslog 和 kern.log 太大

WiFi 问题:安装 Ubuntu 14.04 后 /var/log/syslog 和 kern.log 太大

上周刚安装完 Ubuntu 14.04,WiFi 无法使用。我尝试使用 WiFi,但没有成功,于是我开始使用 LAN 作为工作解决方法。

今天我注意到 syslog* 超过了 50G,而 kern.log 有 15G。kern.log 充满了:

kernel: [32263.171249] iwl3945 0000:10:00.0: Radio disabled by HW RF Kill switch

系统日志充满了:

我已在系统设置中禁用 WiFi,日志已停止。如何停用/删除有问题的 WiFi 驱动程序?

任何帮助,将不胜感激。

听起来你的无线网卡在笔记本电脑的硬件开关处被禁用了。通常有一个功能键可以重新启用无线网卡(对我来说是 Fn+F2),或者设备上的某个物理开关。

如果你在安装 Ubuntu 后更换了无线硬件,这也可能是硬件地址问题,可以通过修改 udev 规则来解决。不过,这听起来更像是硬件开关被关闭了。
