可能会降低路由器速度,导致 ping 时请求超时



环境:

1 router
Multiple LAN servers
192.168.1.1 (HTTP server)
192.168.1.2 (FTP server)
192.168.1.3 (MYSQL server)
...
Multiple wireless devices
Total connected devices more than 50.

当ping到192.168.1.1(不具体(时,这是我得到的

该问题并非特定于 192.168.1.1。我尝试过其他主机,例如ftp服务器,mysql服务器。出现同样的问题。我得到中间请求超时。

然而,192.168.1.1(HTTP服务器(获得最多的请求超时(38.8%的数据包丢失(,而192.168.1.2(FTP服务器(只有2.7%的数据包丢失。

我怀疑路由器的速度导致了丢失一些数据包的问题。如何验证这是路由器的问题,而不是其他问题?

您是否尝试使用其他设备或路由器(如果有的话(?

由于其他主机上没有请求超时问题,因此导致超时的原因似乎与路由器无关。

尝试查看目标主机网络配置(如 iptable(,并将该文件与其他正在运行的主机进行比较。
