如何查看电脑到网关的线路是否连通

查看电脑到网关的线路是否连通的方法：
1Ping本机IP
例如本机IP地址为：22231191211。则执行命令Ping 22231191211。如果网卡安装配置没有问题，则应有类似下列显示：
C:\>ping 22231191211
Pinging 22231191211 with 32 bytes ofdata:
Reply from 22231191211: bytes=32time<1ms TTL=128
Reply from 22231191211: bytes=32time<1ms TTL=128
Reply from 22231191211: bytes=32time<1ms TTL=128
Reply from 22231191211: bytes=32time<1ms TTL=128
Ping statistics for 22231191211:
Packets: Sent = 4, Received = 4, Lost = 0(0% loss),
Approximate round trip times inmilli-seconds:
Minimum = 0ms, Maximum = 0ms, Average = 0ms
如果在MS-DOS方式下执行此命令显示内容为：Request timed out，则表明网卡安装或配置有问题。将网线断开再次执行此命令，如果显示正常，则说明本机使用的IP地址可能与另一台正在使用的机器IP地址重复了。如果仍然不正常，则表明本机网卡安装或配置有问题，需继续检查相关网络配置。
2Ping网关IP
假定网关IP为：22231191110，则执行命令“Ping 22231191110”。在MS-DOS方式下执行此命令，如果显示类似以下信息：
Pinging 22231191110 with 32 bytes ofdata:
Reply from 22231191110: bytes=32time<1ms TTL=255
Reply from 22231191110: bytes=32time<1ms TTL=255
Reply from 22231191110: bytes=32time<1ms TTL=255
Reply from 22231191110: bytes=32time<1ms TTL=255
Ping statistics for 22231191110:
Packets: Sent = 4, Received = 4, Lost = 0(0% loss),
Approximate round trip times inmilli-seconds:
Minimum = 0ms, Maximum = 0ms, Average = 0ms
则表明局域网中的网关路由器正在正常运行。反之，则说明网关设置有问题，请检查IP，网关等信息是否设置正确。
3Ping远程IP
这一命令可以检测本机能否正常访问Internet。比如林大主页的IP地址为：20220411268。在MS-DOS方式下执行命令：“Ping 20220411268”，如果屏幕显示：
Pinging 20220411268 with 32 bytes ofdata:
Reply from 20220411268: bytes=32time<1ms TTL=63
Reply from 20220411268: bytes=32time<1ms TTL=63
Reply from 20220411268: bytes=32time<1ms TTL=63
Reply from 20220411268: bytes=32time<1ms TTL=63
Ping statistics for 20220411268:
Packets: Sent = 4, Received = 4, Lost = 0(0% loss),
Approximate round trip times inmilli-seconds:
Minimum = 0ms, Maximum = 0ms, Average = 0ms
则表明运行正常，能够正常接入内部网。反之，则表明网络设置存在问题或IP绑定不正确。
4Ping DNS IP
这一命令用于检查内部网的DNS是否工作正常，如果您可以正常联网，但是输入域名却无法解析时请尝试该命令“ping20220411266”，如果显示
Pinging 20220411266 with 32 bytes ofdata:
Reply from 20220411266: bytes=32time<1ms TTL=63
Reply from 20220411266: bytes=32time<1ms TTL=63
Reply from 20220411266: bytes=32time<1ms TTL=63
Reply from 20220411266: bytes=32time<1ms TTL=63
Ping statistics for 20220411266:
Packets: Sent = 4, Received = 4, Lost = 0(0% loss),
Approximate round trip times inmilli-seconds:
Minimum = 0ms, Maximum = 0ms, Average = 0ms
则表明DNS服务器工作正常，如果显示“Request timed out”请马上联系信息中心。
