首先，我们看到的是这样的：

/etc/modprobe.d/iwlwifi.conf 第 1 行：忽略以“option”开头的错误行

该文件现内容如下：

选项 iwlwifi 11n_disable=1

该文件被错误地覆盖。它应该是：

# /etc/modprobe.d/iwlwifi.conf
# iwlwifi will dyamically load either iwldvm or iwlmvm depending on the
# microcode file installed on the system.  When removing iwlwifi, first
# remove the iwl?vm module and then iwlwifi.
remove iwlwifi \
(/sbin/lsmod | grep -o -e ^iwlmvm -e ^iwldvm -e ^iwlwifi | xargs /sbin/rmmod) \
&& /sbin/modprobe -r mac80211
options iwlwifi 11n_disable=1

请恢复已删除的内容，然后确定该术语选项带有 s。

接下来，正如您所发现的，当您启动到较早的内核版本时，以太网和无线（我假设）会按预期工作。让我们尝试重新安装 -32 版本。

sudo apt install --reinstall linux-image-4.13.0-32-generic 
sudo apt install --reinstall linux-headers-4.13.0-32-generic

重启。现在一切正常了吗？
