有时,我的 wifi 连接与家用 wifi 调制解调器之间的互联网连接会断开。
我的 Lenovo IdeaPad 310 笔记本电脑上安装了一个 Linux LMDE 操作系统,因此我经常会遇到以下情况:
so@notebook:~$ uname -a
Linux notebook 4.9.0-9-amd64 #1 SMP Debian 4.9.168-1 (2019-04-12) x86_64 GNU/Linux
so@notebook:~$ ifconfig

但是当我的 wifi 互联网断开连接时,我会出现以下情况:
so@notebook:~$ ifconfig
wlp2s0: flags=4163<UP,BROADCAST,RUNNING,MULTICAST> mtu 1500
inet6 fe80::59dc:548c:4eb2:a3e5 prefixlen 64 scopeid 0x20<link>

更新: 根据我的评论:
so@notebook:~$ lspci -knn | grep Net -A3

那么为什么会发生这种情况呢?
