ReadyNAS pro 6 - drops packets when connected to network - direct to PC works fine

Hello,

 

My ReadyNAS pro 6 is dropping packets (ping timeouts, mapped drive disconnects, ssh stops intermittently) when connected to netwrok either directly to router or via switch.

 

Direct connection to PC works fine with no packet loss or dropped connection. Used the same ethernet cable; so that should not be an issue.

 

Please help troubleshoot.

 

Thanks!

Neeraj

    Sounds like a switch/router issue.

     

    Is the PC connected to the same switch?

      The issue persists when both ReadyNas and laptop are connected to same router or same switch.

      When NAS is directly connected to PC, it works fine.

        What MTU are you using?

         

        One thing you can try is to gather the ethernet stats on both the laptop and the NAS before and after a transfer test.  Then you could see how many packets are discarded or errored.

         

        On the NAS you can download the log zip file and look in network_settings.log. 

         

        On the PC (assuming windows), run netstat -e or netstat -es in the command box.  Direct output to a file, so you can get the delta
