The problem is not specific for 192.168.1.1. I have tried other hosts e.g. ftp server, mysql server. Same problem occurs. I get intermediate Request timeout.
However said, 192.168.1.1 (HTTP server) get most Request timeout (38.8% packet loss), compared to 192.168.1.2 (FTP server) only 2.7% packet loss.
I suspecting the speed of the router is causing the problem where it lost some packets. How can I verify it is the problem of the router but not others?
As there is no request timeout problems on other hosts, the reason for causing time-out does not seems to related to the router.
Try review the target host network configuration such as iptable and compare the file with other running hosts.
