Please help in improving the network speed/File access..

[sansub]

Hi,

I have a windows vista (32bit) PC with an E-SATA port. An external harddrive is connected (SATA HD - 5200rpm) to the esata port. When I transfer files to the external drive, I get the write speed of 40-50 MBytes/sec. PC has integrated Intel gigabit Ethernet.

I recently bought Trendnet TPL-401E2K 500mbps powerline adapter (after reading review here) and Dlink gigabit switch. Now the PC and the powerline adapter is connected to the the gigabit switch.

When I tried the other end of the powerline adapter to a laptop (fast Ethernet), I see the link @120-150mbps on the utility. Using filezilla, I got the throughput of 8 MB/s. But, if I unhook the laptop and hook the powerline adapter to my media player (Oplay - 100mbps network), all I get is around 3-4MB/s transfer rate only.

With my settings, I am not sure where the problem is (if any) and how to improve the connection speed (file access) from my PC - media player.

1. Since I was able to write 50MB/s to the drive, it is not the problem with the drive.
2. Windows to windows is 64mbps and windows to linux is 25mbps max.

I tried to disable to the autotuneup on the vista machine but still the same problem.

Could someone please tell me if there is anything that I can do on the windows PC or in Linux to improve the connectivity speed?

Appreciate any pointers.

And what do you measure if you connect the media player to the switch instead of via powerline?

thiggins, Thanks for the response.

If I connect the player directly to one of the port in the switch, I get the sustained ftp throughput of 5.5MB/sec. The player reports the max. file access speed of 45mbps (when directly connected to switch).

So the speed limit is your media player, not your network.

Thanks for the response thiggins.

I posted this question in the player forums but didn't get any response. I wanted to make sure it is not my network issue. I will see whether I can get response from the media player forum. Thanks again.
