频繁掉线,路由器日志内详,求分析
ADSL 路由器共享上网,总是断网,一般重启猫后恢复正常,有时候重启猫也不行

C/C++ code

------解决方案--------------------
只能先替换法排除线路还是设备本身的故障
------解决方案--------------------
先排除是路由还是猫的问题,

直接adsl单机拨号测试先,没有问题,在接路由器测试
------解决方案--------------------
摘掉路由器试试,如果还是断线就请电信公司的给你查一下是线路还是猫的事。
------解决方案--------------------
我之前也遇到过 D-LINK DIR600M 在局域网用PPPOE拨号
一分钟重新连接一次,QQ上下线不停的切换。
建议你换个网络环境,看看是不是路由器的问题。
------解决方案--------------------
最近天气太热,如果设备发热量大的话也会出现这种怪问题。
