今天早上一来, 就发现skype没办法登录了, 不过平时习惯于使用firefox, 发现网页还是能正常看的, 但是使用IE时发现IE也是上不了网的, QQ自然也是登录不了的, 总体的症状总结是:

firefox可以浏览网页, 但是不可以下载;

IE无法上网;

QQ, Skype等软件不可以上;

FTP无法登录;

网络连接正常;

ping可以ping通.

找了半天终于在国外一个网站上找到了解决方法, 命令行下输入:

[code]netsh winsock reset catalog

[/code]

然后重起电脑, 就一切正常了. 英文原文的解释是:

This issue may occur if the Winsock registry keys are damaged or corrupted. Try this: Open the command prompt and type –

[code]

netsh winsock reset catalog

[/code]

This command resets the Winsock catalog to the default configuration.

This can be useful if a malformed LSP is installed that results in loss of network connectivity.

While use of this command can restore network connectivity, it should be used with care because any previously-installed LSPs will need to be re-installed.

出现这个问题, 应该是昨天晚上使用一个软件让我的电脑变成无线基站的原因, 见我前一篇博客:让Windows 7变无线WiFi基站或无线热点.
