以前的自己算是一个不折腾会死星人，但自从学校毕业出来，慢慢的也越来越懒得折腾这些了。
万年不折腾的电脑，今日很奇怪的自己的上不了网了。原以为又是路由器掉线，测试了好几次，其它设备都可以正常连接上网，才确定是自己电脑的问题。
用安装的火绒软件检测下是DNS的问题，麻烦的是用防护软件自动修复也修复不了。
按我以往的的方式得搬出系统重装的大法了，可是这估计得花好几个钟，现在懒得折腾，只能采用Google大法，一番检索检查之后，原因九成九就是所在地区的DNS服务器的IP改了。
直接用CMD命令行试试。
ipconfig /all
ipconfig /release
ipconfig /renew
ipconfig /flushdns
更新了下DNS资源，问题解决了。
