解决办法
1、右击网络图标，点击“网络和Internet设置”，在弹出窗口点击“以太网”，然后在窗口选择“更改适配器选项”，进入 “网络连接”。

2、右击网络图标，打开【属性】窗口

3、在项目中选择“Microsoft网络客户端”，然后击上面的【配置】按钮；

4、在弹出的Realtek PCLe FE Family Controller属性窗口中，点击【高级】选项，在属性栏中选择“IPV4硬件校验和”，将又侧的值选择关闭。然后点击确定，电脑系统会重新识别网络，识别完成后，系统会显示已连接。

5、如果担心给CPU增加负担，再返回把值改回“开启”即可，如果改回开启后不能使用的话，可以一直关闭。
备注：硬件校验和（Checksum Offload），默认是Rx & Tx 开启的 ，这是启用网卡的硬件校验数据包功能， 分担处理器的处理任务， 减少高速传输数据时CPU的占用率，所以从这一点考虑，我们还是开启的好，但有些程序会因为网卡开了硬件校验和造成问题，不过关掉这个功能会给CPU增加负担，如果遇到了问题，或者CPU很好，那就关吧。
