VISTA上不了网的问题~

[深海下的珊瑚]

我的电脑最近突然上不了网了~ 经检查~ 电脑无异常（futureshop检查的）~ 网线无异常~ router无异常~ cable无异常（没有欠费断网）~
同局域网的XP系统电脑可以上网~VISTA的只能用局域网~不能浏览internet~

在百度搜过~ 有的说是网卡驱动问题~ 不明白~ 应该怎么办啊？

可以上QQ之类的聊天软件吗？还是只是不能浏览网页。你看一下开INTERNET 连接共享 有没有取消。

楼主不是第一个有这个问题的 看起来这是一个跟Vista SP1,主板BIOS休眠设置和网卡(Nvidia)驱动都相关的问题。如果楼主的情况符合其中任何一个，小心，上不了网只是早晚的问题；如果有了两个以上，恭喜你加入我们受害者的阵营

废话少说，昨天我也在电脑前花了至少3个小时试图修复我的电脑，还好我的电脑还有一个Wireless网卡。我的问题是由SP1+休眠唤醒造成的，网卡始终拿不到正确的DHCP地址，同网络的其他电脑一切正常。最后我修复这个问题的步骤是，关机，拔掉电源线，等待2分钟，重新通电，开机，一切恢复正常。

如果楼主的问题更加严重，可以试着清除CMOS设置，主板说明书上会有具体的步骤。

请注意，简单的卸载SP1不会解决问题。

hi, cable4sale, if you can ping other computer in your LAN, that means your computer got a valid IP from DHCP server; then can you ping your router?

So you got a valid IP from your router through DHCP, you can ping your router and other computer in your LAN, but you could not browse Internet. Is it correct?

If so, can you ping www.google.ca from your computer?

Hi, Cable4sale, if you can ping google, then it basically means your Internet is working. Did you ping google by name or by IP? If you ping by name, then everything should be working. If you just can't browse Internet in IE, then it is an IE problem. It is a differnt problem than this thread, but I can try to help you

I would suggest you give Firefox a try. If Fox works, then you probably want to do something on your IE.

Hi, Cable4sale, please clarify your problem. The link you gave above is completely different problem. In that case, the user didn't get a valid DHCP IP, it only got a 169.xx.xx.xx, which was when the computer can't talk to your DHCP server(your router in this case) the default IP it assumes.

But you said you could get a valid IP(what was it just in case?) and you could even ping google. The user in that case could not go anywhere, not even ping google.

If you don't know the problem, that is a big problem. Both of us could end up wasting whole lot of time here and still going to nowhere. I would suggest you find out what is the problem first, then start from there

By the way, just for your reference(for the link you gave me), you probably don't want to hot swap cable on a cable modem. Always power off cable modem first and then plug new device into it.

Sounds you are

Here is what you need to do: identify what is your computer problem(i.e, did you get a valid IP or not? Is it a network problem or a IE problem? etc.), make it very clear, then start ask question.

Good luck!
