Title: Transfer rate unstable
Post by: tetedecon on December 10, 2012, 09:52:09 AM

Hi all,

On a my DNS-325 1.03 firmware, i have a strange problem. I am now downloading files from DNS to my laptop over Wi-Fi ( DNS plugged on Switch ). Files are such .iso from 600MBytes up to 3 Gbytes.

During transfer, rate drops down to O Kbytes/s on my laptop and i clearly see the white HDD led activaty stops flashing until it blinks again and rate reach arround 8Mbytes/s. Rate waved until end of download.

Is it a standard behaviour? I could understand this with some Ko files, but strange with big files.

Same problem with direct cable connection laptop to DNS.

DNS setting(s)?

Thanks,

Is this a recent symptom or something that's always happened with your DNS-325? Do you have another PC (other than your laptop) that you can test data throughput?

To be honnest the last time i made the uploading, laptop to DNS, i let the copy gone all night long. Didn't check if everything was ok, because estimated time was more than 1 day  ;D

I just tested same 2.5 Gbytes file from my DNS-323, rate is lower but stable.

27 Gbytes left before download ends, i'll make furthers test later and tell you here.

Thanks for your answer.

FYI - upload throughput (PC > ShareCenter) will be lower than download throughput (ShareCenter > PC).

I made some test. Hard to define where this drop comes from.

What i'am sure about, identical downloaded files from DNS-323 do not show any drops. I both Wifi/LAN connection.

Test made under W8 Pro on two different computers. I will check donwloads with dedicated software such as SyncBack.

I use an application called DU Meter installed on all my client PCs to measure download/upload throughput.  www.dumeter.com.

Humm,

I had same problem from an external USB hard drive disk.

Rate drops.

Copy manager from Windows 8 Pro involved? I will test with a third application copy and see what happen.
