菜鸟你别烦 高手为你解析重装系统后不能上网原因

更新时间：2026-08-18 20:55:37 | 编辑：囚人 | 信息来源：互联网

　　说到重装系统，那是每个网民都要定期经历的一件异常痛苦的事情。从XP到WIN7系统升级，要重装;一个系统用的时间久了，系统不堪重负，启动慢，运行慢，崩溃了;系统不正常，也不知道是啥原因，也不会弄;莫名其妙中了病毒，而且很顽固，杀不了，系统文件随之感染，彻底瘫痪……都是要重装,哈哈,大家还以为今天要讲解的是重装方面的问题,no,no,今天为大家详解的是电脑重装了一次系统后，却发现不能上网了.

　　许多电脑用户碰到过类似的情况，把自己的电脑重装了一次系统后，却发现不能上网了。这就难坏了电脑用户们，是什么原因造成的呢?如何解决呢?一起来看一下有关人员的对这个问题的总结：

　　1.首先要确定你成功安装网卡。新系统是要重新建立一个连接到Internet的连接,按提示来做就行了。

　　2.看网线连接是否正常，用无线的请忽略这条~

　　3.在本地连接 属性那里把连接后通知区域显示图标勾上，就能看到小电视机了。然后运行cmd ipconfig\renew。或者把TCP/IP设为自动获取，然后运行cmd ipconfig\renew。拨号。

　　4.再确认一下你的IP地址是否正确，尤其是首选DNS服务器，再试一下能否登QQ!能的 话应该就是你的IP问题了

　　5.数据都可以发送接收那是你的网关设置正确是自动的获取的话先用下ipconfig/flushdns再用nslookup看可以解析某个网站

　　6.还有可能是路由器的原因：输入路由IP进入,重设帐号密码,连接.连接不上,有可能是帐号密码不对.拔掉路由,直接连猫拔号试一下
