Problem - Readynas pro rndp600e + netgear GS-Serie Switch

Thanks again for these answers and some very nice and regular trace. They all helped me to definitely find out where the problem was coming from.

The graphs were showing problems when data were being read from my computer, or written to the readynas. I took one very high bitrate video (bitrate : 50mb) and had it read on the network by an xtreamer. Result :

Readynas pro --> gs105e --> xtreamer = OK
Computer with win7 --> gs105e --> xtreamer = Choppy
It was in line with what the graphs were suggesting, the Data transmission coming out from the PC was not stable.

Checked with the driver, uninstalled the network card, reinstalled, nothing solved and then, i found this :

Repairing TCP/IP Winsock Catalog Corruption
1/ Click on Start button.
2/ Type Cmd in the Start Search text box.
3/ Press Ctrl-Shift-Enter keyboard shortcut to run Command Prompt as Administrator. Allow elevation request.
4/Type netsh winsock reset in the Command Prompt shell, and then press the Enter key.
5/ Restart the computer.

I tried again netmeter:


The results are not 100% perfect because at the time of the trace, i was transmitting files from a very active hd (OS + P2P) to see what could have been the worst case. And the video file suddenly could be read without any problem.

Thanks again to this forum and its community for this help, it was precious.
One point : Netgear's email support. Sincerely, 3 days after having been proposed to change my switch to a gs105e, i had as an answer : "I disactivate your case, as i think i've given you the solution and/or answered your question".
I don't know if the readynas website include a FAQ on that kind of technical problem, but i wish Netgear could have proposed me this solution. It would have saved them 2 switches that may have been 100% fine.
