就是从输入ping命令后的一系列做法.谢谢!!1
行得通后给你加分.

Answer 1

首先ping 127.0.0.1，看看是否有如下回应：
Pinging 127.0.0.1 with 32 bytes of data:

Reply from 127.0.0.1: bytes=32 time<1ms TTL=128
Reply from 127.0.0.1: bytes=32 time<1ms TTL=128
Reply from 127.0.0.1: bytes=32 time<1ms TTL=128
Reply from 127.0.0.1: bytes=32 time<1ms TTL=128

Ping statistics for 127.0.0.1:
Packets: Sent = 4, Received = 4, Lost = 0 (0% loss),
Approximate round trip times in milli-seconds:
Minimum = 0ms, Maximum = 0ms, Average = 0ms

如果是，说明自己的网卡没有问题，否则你的网卡是坏的

然后ping www.baidu.com，如果出现：
Pinging www.a.shifen.com [202.108.22.5] with 32 bytes of data:

Reply from 202.108.22.5: bytes=32 time=352ms TTL=50
Reply from 202.108.22.5: bytes=32 time=348ms TTL=50
Reply from 202.108.22.5: bytes=32 time=345ms TTL=50
Reply from 202.108.22.5: bytes=32 time=346ms TTL=50

Ping statistics for 202.108.22.5:
Packets: Sent = 4, Received = 4, Lost = 0 (0% loss),
Approximate round trip times in milli-seconds:
Minimum = 345ms, Maximum = 352ms, Average = 347ms
说明你可以正常浏览网页，如果是如下的结果：
Ping request could not find host www.baidu.com Please check the name and try again.
那么说明你的DNS解析出现问题，或者你不能上网。
如果是这个结果的话，那么你需要继续判断到底是不是DNS解析的问题：
ping 202.108.22.5
如果返回如下结果，说明就是DNS解析出错，
Pinging 202.108.22.5 with 32 bytes of data:

Reply from 202.108.22.5: bytes=32 time=375ms TTL=50
Reply from 202.108.22.5: bytes=32 time=376ms TTL=50
Reply from 202.108.22.5: bytes=32 time=375ms TTL=50
Reply from 202.108.22.5: bytes=32 time=374ms TTL=50

Ping statistics for 202.108.22.5:
Packets: Sent = 4, Received = 4, Lost = 0 (0% loss),
Approximate round trip times in milli-seconds:
Minimum = 374ms, Maximum = 376ms, Average = 375ms
否则，那是你还没有连接到网络上。
