突然一直断wifi, troubleshoot 诊断 default gate way has changed

ELFofWAR

我的电脑是hp pavilion g4-2027tx ,今天上网的时候
突然发神经
一直断线（那个wifi右下角有个黄色感叹号)
已经确定不是rounter问题， 我troubleshoot后 它显示 default gate way has changed
修好后过一下下然后又断
我快疯了怎么办啊=3=我google了发现类似问题并不多，我照着一些setting调了还是无效

p.s. 我有用迅雷精简版下载东西，可是后来没打开迅雷也是会断线
我用火狐，antivirus是avira free
windows 7 home premium

确定不是router问题？假如 connect to 其它的 wifi network 呢？

ELFofWAR

确定。
其他device没影响
而且我去其他地方上网也是一样==

disable 然后 enable过  或者repair ，setting放 automatically obtain就可以了

还不能就是network adapter有问题了。

要是你是用lan 会有问题吗？

ELFofWAR

lan??你是指wired connection吗？
wired connection没有影响，还能正常使用

然后我的wifi发神经的时候，连周围其他wifi的存在都detect不到==

RalphLim

LZ之前我的电脑也是同样情形。。。但我过后用了这方法已经解决掉了。。。请查询电脑Device Manager...
1. Click View > show hidden devices from Device Manager Windows
2. expand network adapter (如果network adapter里面有很多6to4 Adapter or Microsoft 6to4 Adapter,那么就要把它清除掉）

这网站有指导怎么清除6to4 remove steps

希望可以帮到你

叫起他人不要连接你的wifi，让你的电脑先连接。

junglk

去 open shred network===> manage wireless network===> 将你的SSID删除。再从新连接。

感谢各位网友的帮忙，问题解决了
朋友教我reset internet protocol 就解决了


自从windows update之后我的电脑就发神经了
上网一直断，开火狐一直提示set default【明明已经set了】，warcraft3 游戏 单人模式的user name关了就重设，就连touchpad的synaptic在开机的时候也不会自己开，要重装
