最近的局域网总是断线。这结果说明什么？高手能否帮忙解释：
C:\Documents and Settings\Administrator>arp -a

不知道你的是一台机器掉线，还是多台同时掉线，分析有点麻烦
看以上数据，你的电脑的IP应该是192.168.0.123，你局域网另一台电脑的IP应该是192.168.0.42
ping 192.168.0.42

说明你的电脑和另一台电脑之间是无连接，是不通的；
你可以试着用自己的电脑和另一台电脑分别 ping 192.168.0.1 -t
如果还是显示Request timed out. 说明局域网内的机器和路由器都不通
如果持续显示：
Reply from 192.168.0.1: bytes=32 time<1ms TTL=64
Reply from 192.168.0.1: bytes=32 time<1ms TTL=64
说明局域网没有问题，看一下路由器设置和你的外网吧
如果多台电脑同时掉线，而且外网没有问题、电压正常，最大的可能就是路由器坏了，换一个路由器试一下吧，有ADSL的话也可能是ADSL的问题，
连默认网关都出不了，就更别谈上网啦。你自己机子设置是否有错，修复下
