  <p>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 <strong><em>intermediate</em></strong> Request timeout.</p>
  
  <p><strong>However said</strong>, 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.</p>
  
  <p>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?</p>
