Ubuntu 16.04：内核更新后无法连接到 wifi（4.4.0-116-generic）

  • 772

将内核从 112 升级到 116 后，我的无线出现问题。我尝试重新安装 bcmwl-kernel-source 并将 gcc 更新到 5.4.1，但无济于事。即使重新启动到 112，我也失去了无线（以前重新安装 bcmwl-kernel-source 对我有用）

似乎 bcmwl-kernel-source 的重新安装运行良好，直到我收到此错误的 modprobe 阶段：

modprobe: ERROR: could not insert 'wl': Exec format error

我可以通过以下命令复制它：

sudo modprobe wl

我认为 wl 模块存在问题，并且 dmesg 中 wl 的 grep 显示：

wl: version magic '4.4.0-116-generic SMP mod_unload modversions ' should be '4.4.0-116-generic SMP mod_unload modversions retpoline '

我对 ubuntu 相当陌生，不知道如何解决这个问题，所以我绝对可以使用一些帮助。

这是 lshw -C 网络的输出

wl:
Running module version sanity check.

Good news! Module version  for wl.ko
exactly matches what is already found in kernel 4.4.0-116-generic.
DKMS will not replace this module.
You may override by specifying --force.

depmod....

这是modinfo：

modinfo wl | grep vermagic

    通过以太网、系留或任何可能的方式建立临时工作互联网连接，打开终端并执行以下操作：

    sudo apt-get install --reinstall bcmwl-kernel-source

    重新启动并让我们知道结果。
